EcoFlow WAVE 2
Idéal pour : Idéal pour le camping en tente ou un petit van bien isolé, avec une installation à deux gaines correctement évacuées.
En bref : Le consensus Reddit décrit un climatiseur compact capable d'apporter un vrai soulagement dans une tente ou un petit volume bien isolé. Sa puissance limitée hors de ce cadre, la fiabilité majoritairement mal évaluée et la gestion des condensats imposent toutefois de fortes réserves.
Au-delà de ce modèle, la marque EcoFlow (toutes gammes) recueille 22 % d'avis positifs sur 279 utilisateurs Reddit. Ce signal marque ne compte pas dans la note du modèle ci-dessus.
Points forts
- Refroidissement convaincant en tente et dans certains petits volumes
- Format compact apprécié pour le camping et les déplacements
- Consommation jugée modérée par plusieurs utilisateurs en mode éco
- Pilotage par smartphone et mode sommeil utiles lorsqu'ils fonctionnent normalement
Points faibles
- Puissance souvent insuffisante pour une grande pièce ou un van très chaud
- Pannes, problèmes de pompe et bruits anormaux fréquemment signalés
- Rapport prix-refroidissement jugé défavorable hors promotion
| Critère | Note /10 | Ce qu'en dit le consensus |
|---|---|---|
| installation | 3.1 | Les utilisateurs Reddit conseillent deux gaines évacuées dehors, une gaine chaude isolée et des flux bien séparés pour éviter une forte perte de rendement. |
| refroidissement | 3.0 | Les retours Reddit sont favorables en tente et dans les petits volumes isolés, mais souvent décevants dans les espaces grands, vitrés ou très chauds. |
| bruit | 3.5 | Le mode sommeil convient à certains utilisateurs, tandis que d'autres rapportent un niveau sonore élevé, des vibrations ou des sifflements liés à la vidange. |
| fiabilite | 1.4 | Le consensus Reddit est majoritairement négatif en raison des erreurs et pannes récurrentes, malgré un témoignage positif après deux ans d'usage. |
| consommation | 2.3 | Le mode éco et l'alimentation directe sont appréciés, mais l'autonomie sur batterie reste courte lorsque la demande de froid augmente. |
| prix | 2.1 | Le tarif neuf est souvent jugé trop élevé pour la puissance disponible, alors que les offres reconditionnées ou d'occasion sont mieux accueillies. |
| commandes | 1.7 | Le contrôle mobile et le mode sommeil sont appréciés, mais les capteurs, le micrologiciel et la connexion au service distant suscitent aussi de nombreuses critiques. |
| condensats | 2.2 | Les avis mentionnent une production d'eau parfois importante et des pannes de pompe, le drainage continu ou par gravité résolvant certains cas. |
| mobilite | 8.6 | Le petit format facilite le transport, même si les gaines et l'isolation ajoutées réduisent la simplicité nomade. |

Man I’m sorry you’re in this situation. I would almost suggest return the Waze 2 and using the month for something else or paying off the loan. Unemployment and homeless, idk if a “luxury” item like the Waze 2 is ideal. I know you’re scrambling to keep you and your dogs safe. I’ve stopped by some of the subs for people really down on their luck living on the streets or in the car, and I can’t imagine buying the wave 2 being an idea. Sorry I can’t offer any good advice but I do hope things get better asap.

IntelligentDeal9721 🇬🇧r/Ecoflow_community · EcoFlow Wave 2 Portable AC Review: Overhyped, Underperforming, and Not Worth It →
I think a lot of people have no idea what the capacity of the Wave 2 is. It's about 1500W. It's not going to handle a large space, a poorly insulated space, or magically cool something in 5 minutes. Physics dictates otherwise because of the power limits needed to run it off batteries. The standard battery for it is also NCM so not only really expensive but also only 800 or so cycles. Our wave cools and heats a somewhat bigger than 10m2 room that's in an awkward spot to cover with the other heatpumps just fine, but it's passably insulated (18" stone) and nobody expects it to magically do the job in 5 minutes. More of a problem for general as opposed to camping type use though is that it's not really able to operate dual hose below 4C or at very high temperatures. For our bit of Europe that is fine but for a lot of places that is not. As a 1500W heatpump/aircon it's fine IMHO - but it's hyped up to be a lot of things it is not.

Zpoc9 🇬🇧r/Ecoflow_community · Wave 2 at Burning Man inlet question →
What you are doing is "single hose" setup. You are using the air within the yurt to absorb waste heat, and then you expel that air out of the yurt. That missing air then is refilled by outside hot air being sucked into the yurt through gaps, thereby heating up your yurt. After you run the wave2 in such a setup for a while, the yurt remains the same temperature as the outside, the only cool area to be right in front of the blower. If you are very worried about dust, you can periodically take off the rear shroud and clean it, or maybe set up a filter box similar to a Corsi-Rosenthal box.

DependentSky8800 🇬🇧r/Ecoflow_community · Wave 2 is dangerously terrible. →
I’m sorry but this isn’t a “dangerously terrible” product. I have two of them and you have to understand what they are designed for. At the end of the day this is a 5100 BTU air conditioner. It isn’t remotely powerful enough to keep a car cool on a sunny 90-100 degree day. Cars are poorly insulated sealed metal boxes that regularly get to 120°+ in the sun turned off. At best you’ll get a 20° difference in air temperature out of this air conditioner which still puts you at 100° range. Where this air conditioner will shine is at night when it doesn’t have to fight against thousands of BTUs worth of heat from the sun. I regularly use mine while camping in central Florida, it makes zero difference during the day but at night in my tent it makes a massive difference. As for your tough times, I thoroughly feel bad for you and wish you nothing but the best in getting a job and getting back on your feet. My advice? Return the financed Wave 2, save the money on gas to idle your car & use its air conditioning system when absolutely necessary. Reach out to friends, family, trusted colleagues, anyone who may be able to lend you a hand.

ViciousXUSMC 🇬🇧r/Ecoflow_community · Planning on getting EcoFlow Wave 3 to replace a portable AC in my apartment, is it worth it? →
Absolutely not (IMO) it's expensive and low powered. I have the Wave 2 and it's not as good but at least gives me similar real life experiences. It's design hinges on maximum portability and independent power, both of those not important for an apartment. So you pay a ton extra for those features while still falling short on what matters (performance and reliability) Get a portable AC heat pump unit with dual hoses or a window unit if your allowed to use one. Midea makes really solid inverter units that are very quiet and energy efficient.

tricid 🇬🇧r/Ecoflow_community · Question. Is Wave 2 better than Wave 3 or something?? This product seems to fit what Im looking for, but the amount of negative posts/comments arent reassuring →
I'm going to offer a slightly different perspective than the one other comment (so far). When I bought my first ecoflow products, this subreddit was mostly positive. I think their new products are having issues/quality is going down/support....well that one I don't know. It seems like support always kinda sucked. With an asterisk. I bought two wave 3's. One broke on its first use. Support was slow and tedious, but they did ultimately replace it outright. So it was worrisome getting there but in the end they did make it right. That seems like a common story with ecoflow. Then there seem to be some more rare outliers that struggle to even get that. Do with that info what you will. Now that I have two functional ones, I like them a lot. They do what they're supposed to do. They're portable, they cool well (on normal and max). I feel like they've elevated my camping experience quite a bit. I am concerned that a lot of the posts have very similar failures related to the 110v input port with the wave 3. It's how one of mine died almost out of the box. But its replacement and the other one are going strong so far. It's also concerning (annoying) that you can't seem to buy/replace some of the accessories that come with them that are necessary for use. Such as the duct adapters. Good luck if you break one. Then it seems as if once they launch a new version of a product, all support for the prior version immediately stops. But I have seen posts where dead units still within warranty get replaced with the newer version. And finally, where I just agree with the other poster, I do think they just missed the mark a bit. Now that I have them I think I would have been happier with the wave 2. I think I would have traded fewer btu's of cooling power for the lower power draw of the wave 2.

its_an_armoire 🇬🇧r/Ecoflow_community · Wave 2 is dangerously terrible. →
This is only a temporary solution, but the only way the Wave 2 is going to be useful to you right now is if you can find public parking with some shade, keep the unit on your trunk with the output tube going into the car, and find new parking if you get told to leave. Not ideal, I know. Hoping for the best for you and your dogs.

Complex_Solutions_20 🇬🇧r/Ecoflow_community · Wave 2 is dangerously terrible. →
I do agree, the marketing (let's be real - Ecoflow and most other small similar units) is quite misleading. The battery power station marketing isn't much better how they imply a small unit can run an entire house for days or weeks. With sufficient insulation, it could likely keep a van at an acceptable temp for living. Stock...I doubt it.

That vent hose adds a lot of heat to your space. The trick is to find a way to get the AC as close to the vent window as possible, so you can keep the exhaust hose run as short as possible. If you can't do that, then insulate the exhaust hose by putting a blanket around it.

dark79 🇬🇧r/Ecoflow_community · Wave 3 are totally unreliable, 2 units have died in under a year →
My Wave 2 was a dud and Ecoflow replaced it and battery with a Wave 3 and battery and I'm super grateful for it. The Wave 3 was barely just released at the time and my Wave 2 was from their eBay return store. So IMO, they went above and beyond. That said, I use it in a pretty unconventional way: to keep a large grow tent I have (2) resin 3D printers in at a stable temp during Midwest, US summers. The grow tent is in an unattached, uninsulated garage, so it's a challenge outside of ear spring and fall to actually print things. Wave 3 has been doing a solid job for me. It runs for around 6 hours a day with the evenings and early mornings not needing cooling. I've been using it since it launched with no major issues outside of MPPT error when I have too much solar trying to go into the battery. All that said, I'm not really convinced that it the usage it's actually designed for (cars and camping) that it's a very good product. I mean, if you're in a shady area, maybe? Bit overall the cooling and especially heating seem very underpowered.

PVPicker 🇬🇧r/Ecoflow_community · Squealing noise from Wave 3? →
I have the wave 2. It's done that one or twice. Seems to be the auto-drain pump thinking there's water when there isn't. Usually toggling drain to manual and then back fixes it. Also just purging anything in there helps.

Mik3-Wazowski 🇬🇧r/Ecoflow_community · Brand new Wave 3 - horrendous sound from water drain pump →
Solution: (CAVEAT: Before the pump eats itself) Had this EXACT problem with my wave 2 and dreaded the thought of warranty and time turn around. Grabbed a few bottles of drinking water and poured in the front and rear to flood the sump. (To the point of water running out over the sump to help remove debris) Unit triggered an alert for overfull and cut cooling briefly while it pumped out the excess, and it really spat out a good stream of water. Suddenly noise free and returned to silent operating. Threw a few more bottles through because why not. Upon inspecting with a light, there are rusty screw heads in the sump (despite always draining it after use) and figure some debris was trapped in the pump. Free it up with a whole lotta flow and back to normal operating.

OppositeDowntown5149 🇬🇧r/Ecoflow_community · Trying to decide if the Wave 2 or 3 can fit my camping needs.(mostly looking for similar experience but helpful advice is welcome) →
If you're just looking to make sleeping in the tent more comfortable, rather than trying to air-condition the whole thing like a hotel room, the Wave 2 is probably enough. And the sleep mode does help, it won't be running flat out all night, so the noise is a lot less noticeable when you're trying to sleep.

Driveformer 🇬🇧r/Ecoflow_community · Question. Is Wave 2 better than Wave 3 or something?? This product seems to fit what Im looking for, but the amount of negative posts/comments arent reassuring →
1. It’s just human nature that pissed off people post more than pleased people. 2. Wave 3 is fine, so is the 2. I have both. For a small van a 2 with an insulated hose is probably plenty. 3. People hate the wave because of the price and the higher wattage in the same footprint. Ecoflow just missed the mark; either make it cheaper, make it smaller, or make it more efficient. It did none of those things. Now, the drainage system is way better and it has some nice extra features and for my needs in the back of a small trailer hooked up to a pro 3 I love having the extra output. But I’m a minority on the use case, if I didn’t rearrange the trailer constantly for different jobs or completely empty it to put vehicles in I’d be stupid to not use a mini split over a wave 3.

CaterpillarKey6288 🇬🇧r/Ecoflow_community · is it worth upgrading from wave 2 to wave 3? →
They are both under powered. 2 is 5100btu the 3 is 6100 btu. If you don't need the battery get a portable ac instead. From most test neither one has much cooling power. Most test I've seen on a camper they only cool a few degrees after hours of use.

I have a Wave 2, I wish I would have bought it with the battery. It's stupid the cost of just the battery by itself. Anyways, make sure you vent it properly or it won't work that well. It sounds like you have 600AH of batteries plus the Wave battery. Are you using solar or charging off the vehicle? If you don't have something like a DC to DC charger already Renogy makes a cool 40amp one that will pull direct from your alternator and also has solar hookups.

maydisturb 🇬🇧r/Ecoflow_community · Wave 2 has a defective drainage and can't be fixed →
Sorry you got bit by these - I did too. I've been completely turned off of EcoFlow after the experiences I've had with the Wave 2 and their nonexistent QC for refurbished products (Delta 2 Pro). On the Wave 2, they made the drainage hole so small that the water can't get through it. The only way to actually fix it is to expand the hole so that the surface tension of the water can't prevent it from flowing. But even then, the drain pan itself is not sealed and doesn't have high edges, so any tilt will cause the excess water to drain out the bottom onto the battery. It's a shit design and the only way to use this thing is to leave it half-tilted over a 5 gallon bucket to catch the runoff. Definitely gonna be looking for a sailboat AC or something similar when this thing kicks the bucket.

I’ve already clean the drain plug and cleared the area of any rust. The pump is just not working anymore. The only way for the unit to drain automatically is to have it elevated and tilted with a recipient underneath which is particularly inconvenient… more over not to have any spare parts after only 3 years sucks. Welcome to planned obsolescence I guess

KokakGamer 🇬🇧r/VanLife · Van Aircon (ecoflow wave 2 + delta 3 extra battery + 12.8v 100ah lifepo4) very rough proof of concept →
Today is the first time I'm really testing it with the 12.8v battery. With just the ecoflow expansion battery alone it lasts 3 hours at max cooling. Assuming the AC takes 333 watts. (1024 / 333 = about 3 hours) The solar input of the Wave 2 is 13amps \* 12.8 volts = 166 watts. Effectively we're taking 166 watts from the ecoflow expansion battery. So ecoflow battery has 1024wh / 166 watts = 6+ hours theoretical. I'm going to say 5 hours it looks to be, but that's just limited by the voltage of the lifepo4 battery. I have a 25.6v 100ah that I'm charging right now and will swap the 12.8v next time. That would send 332.8 watts that would hopefully top the ecoflow battery nearly not losing any internal charge. Or at least only take maybe at most 30-40 watts. If that was the case, it should last quite a lot longer. Maybe 10 hours. I don't have real world data yet though, and its about to rain it looks like, so I have to take it down.

zulubravo80 🇬🇧r/Ecoflow_community · Wave 3 (Underperforming Wave 2) →
Honestly, after owning a wave 2 With battery for a couple of years now I’m convinced that it’s more effective to call it a dehumidifier than to be sold as a viable heater/AC unit. Especially in the context of camping where if you need a portable heater, it is far more cost-effective to buy a self-contained diesel heater which if you only use a couple of times will still leave money in your pocket. I’ve done a few tests in my small camper trailer employing multiple external sensors, and the results are laughable compared to a cheap Kmart element heater hooked up to one of the EcoFlow battery systems, at least one of the battery systems could be used for other applications beyond heating and cooling. Got me good!

vlad_1492 🇬🇧r/Ecoflow_community · Ecoflow wave 2 on constant heat mode. →
Seems to do the same, set it for always on 'MAX' mode and it cycles down frequently. Have not found a way to correct, override, or use an alternate temperature sensor so far. Heat output seems minimal when the air intake temperature is close to the lower limit of the design spec. Right now my intake is around 7C and the heated space doesn't get much past 14C but it will cycle down anyway. Interestingly mine frequently shows ambient as 'lower' than actual by quite a bit. It has only been in use for a week or so. Have a support ticket open. Probably going back.

hz55555 🇬🇧r/Ecoflow_community · Wave 2 (worth the gamble) vs Wave 3 →
Well if you want I'll ship you one :) Can get the unit + battery for around $850 + tax now. Actually I saw that combo go on sale for $799 but with the right codes and credits and luck I'm thinking it will be down to $700 again sometime soon. You have valid points, the point of the unit is to balance cooling & energy efficiency and I think they can probably push both with various incremental improvements (like even a better refrigerant). I think the form factor too can be pushed a bit too... larger a bit won't really make it less portable but you squeeze more performance. I'm honestly shocked that there isnt a portable ac that is a cube/horizontally wide shaped vs all the tall rectangles. LG or Hisense could just repackage one of their units in a different shape and that would work for a van imho

AnyoneButWe 🇬🇧r/Ecoflow_community · Wave 2 at sub zero →
Short circuiting the exhaust will make the exhaust temperature go down forever... It will shut down and do nothing at 40°F. So ... You would need to ensure the air coming into it is above that temperature. It is a heat pump. It is taking in "outside" air, extracts heat and exhausts colder air to the outside. It will block/freeze up if the outside air gets cooled down to below freezing.

The connector in picture should be able to handle what is specified in car charging in these specs, it is a yellow XT60 which will let the battery know to constrain it to car specs. The Orange XT60i which you don't have has a third lead that lets battery know to accept higher solar input although it appears your input watt limits are the same either/or. All good.

My Wave2 has been fantastic for the last two years. I have a family of four and we've used it countless times in the Texas summer heat to cool our tent during Overland camping trips. In fact we wouldn't have been able to camp at all due to the heat without it. It will work during the day but certainly is more efficient at night. I also bought the extended battery for it. Sorry to hear that it hasn't worked for the OP but my experiences have been great.

You’re right, it does. If you can get an old blanket you can cut it into strips and wrap them around the hoses. Even though the exhaust hose is hotter, insulate both of them. The only other suggestion I have is to position the Wave 2 so that the hoses are as short as possible.

I have a 12v inline fan attached to a duct splitter with one hose going into my dogs crate and the other going to the living area. I can deff feel the difference with a/c and heat when I’m using the fan vs not using it. My wave 2 is on a semi permanent set up with the exhaust and intake being ducted through the wall of my van. It drains through the floor but sits inside of a pan with a water leak sensor in it just in case. The whole unit is under my bed where it isn’t easily accessible and I control the whole thing (including the additional fan) with my phone.

So that changes the situation. The cable can handle 300V voltage and so the European voltage of 230V is not a problem for it. The problem is in the cable end, where you have 120V indicated. And that is the weakest link. This end might not handle 230V. That is why you get different answers, someone reacts to the cable and someone reacts to the end. I recommend that you do not use a cable with a 120V end in Europe.

Relevant-Scarcity864 🇬🇧r/Ecoflow_community · Need help finding/replacing EcoFlow Wave 2 fan motor or FU6831Q controller →
I rarely comment on posts, but I felt I had to on this one. My Wave 2 developed what sounds like the exact same fault last week. In my case it happened immediately after updating the firmware, although I can't say for certain the two are related. I've been in contact with EcoFlow support, and unfortunately they've been unwilling to help me get it repaired. I wasn't asking for a free replacement—I jsut wanted a working unit without being out of pocket. Instead, the only option I was offered was a 5% discount on a brand new unit, which honestly isn't much of a solution. I've invested quite heavily in the EcoFlow ecosystem over the last few years because I've always rated their products. That's why this has been so disappointing. A product like this shouldn't become effectively disposable because a single fan motor fails, especially when customers are actively trying to repair it. To the OP: if you manage to find a supplier for the replacement motor or any more information on the part, I'd really appreciate it if you could update the thread. I'm in exactly the same position.

PhraseWeekly9631 🇬🇧r/Ecoflow_community · Question. Is Wave 2 better than Wave 3 or something?? This product seems to fit what Im looking for, but the amount of negative posts/comments arent reassuring →
We actually ran the Wave 3 through a pretty thorough test last summer in a van and awning setup so this is a question I can give you a real answer on. The Wave 3 has more cooling power, 6,100 BTU vs 5,100 on the Wave 2, and pushes significantly more airflow, 330 vs 250 cubic metres per hour. In a van that difference is noticeable on really hot days. The dehumidifier mode is also a genuine addition, not a gimmick, especially in a small space overnight. The battery is the biggest upgrade though. Wave 3 uses LFP chemistry which gives roughly 5x the lifespan of the Wave 2 battery. If you're using it regularly that alone justifies the price difference over time. If you already own a Wave 2 and it's working for your space, the upgrade is hard to justify. If you're buying new, the Wave 3 is the one to go for.

I'm not sure about the wave 3 but before it goes out of warranty I would go ahead and order a pack of those [sensors](https://a.co/d/0d0oCBS8). with any luck it will be the same one and you'll save a couple days waiting on them. If you are handy with a multimeter you can verify the sensor type by setting resistance and looking for the resistance to go opposite of the temperature change. if you are close to warranty expiring with this new unit I would advise taking it apart and checking the wire routing for all the sensors to eliminate any bending. If I remember right the old sensor actually had enough extra to build in a small loop to give room for the compressor to wiggle. Mine was pulled tight so it broke off right at the base of the sensor.

If you have made sure the unit is sitting on level surface, then most likely the water level sensor is not working correctly. I would reach out to Ecoflow. During the previous UK heatwave (30-34C), my unit (which is a Wave 2) can chill 25C ambient air to ~14C on max power. If your unit is new out of the box, it's possible it has been transported sideways or upside down. You'll have to let it sit the right way up for at least a couple of days to allow the lubricant oil to flow back before running it again.

NeatPack4269 🇬🇧r/VanLife · Ecoflow Wave 2 →
I don’t think your jackery will cut it. You can join the eco wave community to see setups. For one hour of operation in maximum cooling mode, you would need a battery with a capacity of roughly 430-590 watt-hours (Wh). So you’ll need to look at some math based on your battery and usage. I had the wave 1 with battery pack when it first came out, and just got the wave 2 this summer. Makes a lot of difference for me my pup (I have a Chevy conversion high top). But I have a 300aH battery system hooked to solar and also charges when I drive. The deltas that can power this are just as big if not bigger than the wave unit itself, so you’ll need to account for additional space. As for draining, there’s a self drain option.

Hello! Thanks for your comment. I'm looking at the Wave 2 because I have been able to find some refurbished models for a good price online ($350-$500 with shipping). I'm looking to cool my un-insulated minivan at least 10 degrees F. I have a small jackery but assume I'll need a much larger battery bank to run the wave for the entire evening. I do have insulated window covers. My van has a flat center console that I was intending to park the Wave 2 on with a custom hose adapter for the front passenger or drivers side window. Drain hose, I have no ideas on currently but perhaps a plastic drain tub under the console would be good.

XYZVECTOR_AGD 🇬🇧r/Ecoflow_community · EcoFlow Wave 2 Portable AC Review: Overhyped, Underperforming, and Not Worth It →
Okay I have one of these devices and op says followed the instructions that is not really explaining how the unit was set up. If you don’t use the hoses to exhaust the condenser air this thing doesn’t work at all. Also you need to keep in mind this is designed to cool a tent at best a 10m2 room is 100m square and op doesn’t tell us how high the room is so let’s say it is 10m tall so that is 100m3 room. This is not powerful enough for that space. You need about 11,000 btus. Now EF doesn’t tell you in it’s marketing literature how big the area it is cooling in 5 minutes. However I would venture to say you will start feeling cold air in 5 minutes coming from the unit. It is a small air conditioner it will cool 1 cubic meter 6 deg F in 1 minute. However a 100 sq meter room no way, too small sorry op. You got suckered, you need a lot more cooling capacity than 5,000 Btu. You need at least 10,000 btus if you want 5 minutes your probably closer to 15-20k Btu but that would short cycle and waste a ton of energy. Also the unit works a little better if it is outside the room it is cooling. Anyways the wave2 works well if your cooling or heating load is less than 3,000 btus however 3,000 btus is not much and don’t expect miracles from this unit. You can get up to 5,000 btus if the outside air is not to extreme but I wouldn’t count on it. However op has severely undersized heat pump solution for the area trying to be conditioned.

I agree with OP. after 3 months of use last year I decided to shelf it and go with a 12v mini split as the Ecowave 2 was loud, a power hog for its power usage, and is horrible with managing water condensation such that I've spilled the lot multiple times or while running while sleeping overflowed a 40-50oz cup across multiple random nights. this thing is horrible with its water self evac. also if the internal water capacity gets high because it doesn't consistently expell through the exhaust, it'll shut off the air conditioning entirely. I've complained to ecoflow that the self expel function needs to keep the water pump on 100% but it doesn't, it cycles and does a horrible job doing so.

I was going to say that also. One of the canopies over it. That was actually my next step myself. I originally started off with the zero breeze mark 2. With the moving blanket stuff. An it worked. But I’m in south Louisiana. So it’s humid an hot. But I did that with that one I believe like April. No way could I later in the year. But it wasn’t no good until it got a little after 8pm it was able to make it comfortable. Like as far as not muggy sticky feeling or hot. It was just at the border of comfortable an doable. The wave 2 was a lot better. But run time it was more the power hog. But it definitely can be done. Least for me. I’m not sure if it could be done in mid summer. Not even sure ild try. It’s miserable. Hot an humid mid summer. So even if the tent would be cool an dry. Just trying to enjoy the outside would not be enjoyable enough. So I’ll be doing the pop up canopy next also. But what I believe I’ll end up doing. Is looking into the Crux Crua Tents. So you have a tent shell as normal. But it has a whole like quilted insulation that can be put in it. That insulates the floor walls ceiling everything. An I believe has ports for AC hoses to be run out. That’s the only one I found seems like would be just right. Theirs not to many AC insulated tents out there. Theirs AC ready tents with ports out there. But not insulated.

HeWhoQuestions 🇬🇧r/Ecoflow_community · EcoFlow Wave 2 Portable AC Review: Overhyped, Underperforming, and Not Worth It →
It sorta works - I've seen the same issues as OP though, plus I've already had one warranty replacement as it stop accepting AC power (an issue other have had) and without that you can't even start it up with DC power if the battery is fully dead. The new one has a different issue where the drainage phase randomly wakes me up with a shrill screaming noise. Driving it from DC is what's been the most disappointing - you cannot do so without the addon battery, no matter how powerful your DC source is (because it's assumed to be unstable solar or insufficient car 10A). So I sprung for the combo with the battery. But then had to get an XT60i cable, since with a standard XT60 cable it assumed my power station's consistent 12V must have been car power and limited itself to 8 amps. I then had to modify the XT60i cable to flip the jumper pin around to get it to assume solar and now it will pull up to 600ish watts... but never more, even though at max, the Wave needs like 800watts. The only way to give it max, without an EF power station specifically, is to plug it in to AC power. Reportedly, that is somehow also more efficient. The 600W limit is fine for a long time on Eco mode, but on anything above that the battery won't last, despite constantly being charged. So even though I have a constant source of unlimited DC power going in, as soon as the addon battery gets low the unit switches to "fan only" mode. It's then stuck there until you switch it back - it will never go back to Cool on its own and you might not notice for a while since you still hear it blowing. So unless you have a whole EF ecosystem already, or want to hook your solar up directly to the Wave and nothing else, you won't be able to sustain all functions on DC alone - just Eco mode. Eco mode doesn't try very hard, I often find it blowing out hot air.

Below freezing they stop heating and above 80-85+ they can’t keep up. Your room is way too big for this unit. With that said it CAN cool part of it. I have a 5,000 btu window until I use for my computer room to supplement my home AC. When blowing directly on me it gets very cold. The room itself only drops a few degrees.

idkmybffdee 🇬🇧r/AirConditioners · Is the EcoFlow WAVE 2 portable AC unit good? →
My only real issue with them is the price, they're only 5,000 BTU which isn't a whole heck of a lot of cooling for close to $800 us, a comparable 8,000 BTU portable AC that doesn't have a DC option is going to be about $400... Once you start adding in batteries and solar you can put something together much better for the price. You're also not going to be cooling a whole lot of space with 5,000 BTU, it's less powerful than what I would consider a pretty standard window unit. If you're not set on having the convenient battery and only going to use it on shore / generator power I'd save some money and grab an off the shelf portable AC.

DeeJayUND 🇬🇧r/Ecoflow_community · Wave 2 is 70% off. →
I set the unit to 73F and the van gets there within 20 mins in Houston summer. I’ve used it in an emergency, in my house, to cool my 400sq ft master bedroom during an outage, and it cooled the whole room down to 73F in about 30-40 mins. I didn’t time it though, so they’re approximations…

haj42966 🇬🇧r/Ecoflow_community · EcoFlow wave 2 massive condensation issue →
I’ve seen a lot of condensation as where I live the humidity is always very high. I would say that that is the case of where you are plus it may be higher in the tent versus outside because as we breathe in an enclosed small space we exhaust moisture into the air also. The only other option I can think of is to have a small cover or something to protect it from rain. r/Ecoflow_community any suggestions?

Pocket_Silver_slut 🇬🇧r/Ecoflow_community · EcoFlow wave 2 massive condensation issue →
I would be worried about sudden rainstorms running it outside. I took a picture of the amount of condensation after running the unit for about 10 minutes. It seems like an excessive amount to me and it’s also building up on the sides. My worry is that this amount of condensation is going to short something out and ruin the unit. https://preview.redd.it/furgic5rh6we1.jpeg?width=3024&format=pjpg&auto=webp&s=2826b61cff9b07e4f47bfefc5942589c31c657e3

I called them a few weeks ago asking if there would be more Wave 2 units available. The rep told me that the Wave 2 has been discontinued and will no longer be sold after the launch of the Wave 3. That being said, I have been seeing some amazing deals on the second hand market for W2’s… but you take on more risks with a used unit with possibly no warranty.

You're assuming the Wave 2 was built with enough overhead to handle the extra load. But most modern consumer electronics are engineered to hit the bare minimum, and there's rarely much headroom. Even something as simple as slightly thicker wiring, better heat dissipation, or improved insulation could be what allows the Wave 3 to run at higher wattage. That doesn't mean the Wave 3 is better. It may just be engineered to a slightly higher bare minimum. Without those changes, trying to push the Wave 2 further could lead to premature failure.

Agitated_Mess3117 🇬🇧r/Ecoflow_community · Wave 2 - Tips for cleaning playa dust out →
It did great for me luckily I had access to a 24 seven generator so I didn’t have to worry about the battery. I was very pleased with how well the heater worked when it got cold and the AC kept me cool. It wasn’t perfect, but it worked and I was happy. I think it would be difficult to keep it charged up if you’re running only on battery power so keep in mind. You need to have another power source or very clean solar panels to keep it charged up.

I am cooling a 16 cbm trailer (3,40 m long, 2m wide, 2 meters high) with it in summer. it is in the sun without shadow (Bavaria). I use a delta 2 max (2kwh) and 400 watts of solar without external electricity. There is enough solar to fully charge the battery and keep the wave 2 running so the temperature is at about 20 degrees celsius together with a fridge and other gadgets. i think this is a really useful device.

dracotrapnet 🇬🇧r/Ecoflow_community · EcoFlow Wave 2 Portable AC Review: Overhyped, Underperforming, and Not Worth It →
During hurricane Beryl when we had no power, I ran my wave2 off a generator before I got the battery. I knew it couldn't cool the whole house but I had very little options on placement. Kitchen table, out the window. I needed it up high enough I can drain it easily and man I was draining it often. I finally just pulled the plug and had the rear end hanging off the kitchen table over a bucket. It was at least dehumidifying the house a little. I had it running on a generator along with another portable 1800 btu in the office window. 5 days no power in a large house it was 85 F in July in Texas. It was barely bearable shirtless with fans mid-day. If someone needed some relief they could sit at the kitchen table and cool off or go to the office and sit in front of the other portable if it was running. The office portable kept failing, the button board was near the outlet and was getting condensation on it any time I shut it down to service the generator. It had to dry an hour before I could start it it back up. However the wave2 didn't have any issue like that. It just started back up after I restarted the generator after adding fuel no problem.

Kellic 🇬🇧r/Ecoflow_community · EcoFlow Wave 2 Portable AC Review: Overhyped, Underperforming, and Not Worth It →
Honestly? I was and am still considering a wave. However. Companies that try and be jack of all trades...well you know the rest. I'll probably buy something from a company who does exclusively AC / heat pumps. While I have central air the AC was last replaced in 2001. I get it serviced every year but.....That old of a unit I want a backup to use between failure and replacement. Murphy's law dictates it will go out in 100F/37.7C weather.

MrMagichands4life 🇬🇧r/Ecoflow_community · Wave 2 is 70% off. →
I think people had great luck with putting sweatpants on the hoses for cheap and easy insolation, then when it gets too cold to run the heat-pump you can use a cheap resistance heater / use gas, and wear the sweatpants! I wanted to buy a wave 2, but the price was not realistically economical, as I could do twice the cooling with a 12000btu air-conditioner for $400 and buying a few more solar panels and keep using natural gas for heat.

My Wave 2 started making this terrible noise. It seems to correlate to the water pump. When in drain free mode it makes this noise. If I switch it to external drain it continues to make the noise but after it discharges the water and the pump shuts off the sound stops.

Return it and pay back the loan . Start again looking for a new solution without that loan hanging over your head and nothing to show for it. Yes, I do recognize that you might not be able to pay the loan info because of interest charges or something similar , but you would still be better off. ( assuming the terms of the loan allow you to pay it off in quick succession)

It works normally, blowing air/heat, but as mentioned, it shuts off within a minute and shows the error message. the air duct is an optional attachment to help blow air into a specific spot, like into my tent when it worked for the ONE camping trip we used it for. Take a look at the EcoFlow website to see what its capabilities are. Happy to sell it to you, but prefer not to ship. I’m located in Cali.

I've also found something like this ....when I input a 12v car charger (to xt60i) into the wave - while also charging using the D2Max through both solar ports. I also got the impression that it was offsetting the energy input into the Wave (ie., using it but not reporting it). So, with the D2Max and Wave, you have 3 solar inputs - even without another battery attached to the Wave 2. It may only report 2 inputs though. That's been my experience so far.

> I currently own more than 10 EcoFlow products, so I genuinely like and trust the brand. What does EcoFlow put into their products to deserve this kind of customer loyalty? To answer OP's question Gemini brought up a great point. --- Firmware Constraints: Because the motor assembly features an embedded MCU (motor controller) rather than a simple 2-wire plug-and-play design, it may require specific EcoFlow control board firmware to operate correctly. You will have to find a donor replacement. Try eBay to see if you can find a broken Wave 2 that might have the spare parts you need.

Questions fréquentes
Le Wave 2 refroidit-il vraiment une tente ou un van ?
Les utilisateurs Reddit obtiennent souvent de bons résultats dans une tente ou un petit van isolé, surtout la nuit. Les retours deviennent nettement moins favorables dans un grand volume, un véhicule vitré ou un espace exposé au soleil.
Quelle autonomie attendre sur batterie ?
Le consensus Reddit évoque généralement quelques heures d'usage, avec plusieurs retours proches de trois heures selon le mode et les conditions. Le mode maximal et les fortes chaleurs accélèrent la décharge, tandis qu'une alimentation directe ou solaire adaptée peut prolonger le fonctionnement.
Faut-il installer les deux gaines ?
Les utilisateurs Reddit recommandent les deux gaines, avec l'air chaud rejeté dehors et les flux d'entrée et de sortie bien séparés. Isoler la gaine d'évacuation améliore aussi les résultats, car sa chaleur peut sinon revenir dans l'espace à refroidir.
Le Wave 2 est-il fiable ?
Le consensus Reddit est majoritairement négatif, avec de nombreux codes d'erreur, appareils défectueux, remplacements et pannes de pompe. Un témoignage positif fait état de deux années satisfaisantes, mais il reste minoritaire dans cet ensemble.
