EcoFlow - EcoFlow WAVE 3 Portable Air Conditioner

If you need a more compact unit, the Eco Flow Wave 2 or Wave 3 are fantastic. Two summers/winters on my Wave two. It heats at 6100 BTUS and cools at 5100 BTUs. Expensive, yes. However, they can run off of their own battery for 8 hours and can be recharged via solar or car charging.

Is this [the one you are talking about](https://www.diagnostic-expertise.com/3-in-1-portable-air-conditioner)? If yes, I can confirm you do not need to use an exhaustion tube.

The Wave 3 has a few minor advantages that a cheapo unit is unlikely to have: the means to use a battery without an external inverter (waste of money if you can have guaranteed shore power), hose connection(s) to easily route cold/exhaust air, and a heat pump for instances where you want warmth (probably not applicable in FL summer).

We have the same thing happening with ours that we just got two weeks ago. Did you figure it out? :(

Thank you for the honest reply! I mailed ours back today--we need ones for our doggies in the van and no way was that cutting it. We had bought a 12V rooftop AC unit but I was hesitant to have to completely rehaul our van to install it and get a proper battery bank (We power everything off of our Goal Zero right now), but looks like we are going to go that way now. Will be a big van project for this year! Thanks again!!

I tested it in my bedroom, which might as well be a sauna in the summer, and within 20 minutes it went from 'I’m melting' to 'oh hey, this is actually comfortable.' It’s not going to turn your place into an igloo, but for something this small, I was shocked at how well it handled the heat. What really sold me was the battery life. I ran it for a full movie night (yes, all three _Lord of the Rings_ extended editions, don’t judge me) and it still had juice left. And it’s so easy to move around—I carried it to a friend’s garage hangout when their AC died, and suddenly I was the hero of the night. On eco mode, it’s quiet enough that I could sleep without feeling like I was next to a jet engine. That said, it’s not perfect. The app is kind of a mess—it keeps forgetting my settings, and half the time I have to restart it to get it to connect. And if you crank it up to max, it does get a little loud, like a window AC unit on medium. Not unbearable, but noticeable if you’re trying to have a conversation. Still, after returning three other portable ACs this summer, I’m keeping this one. It’s not magic, but it’s the closest thing I’ve found to beating the heat without installing a permanent unit. If you’re on the fence, just go for it—worst case, you join the club of people who finally stopped sweating through their sheets every night

No air con runs off 8 A (thats what your cig port output is). The "best" portable air con is EcoFlow Wave, however that requires AC, but you can get a big power station that can be charged via DC to power it. The "best" installed air con thats DC (i.e., 12 or 24 V) is Cruise N Comfort. Neither are cheap, both require a lot of amps. Anything smaller is probably not worthwhile. I have personal experience with both in my van

Only use a two hose air con with the hoses properly insulated and exhausted. I'd strongly recommend the EcoFlow Wave 3 if you want to go with a portable option but for a cheap option an RV air con installed in the roof is the way to go, I would recommend at least 8K BTU and an extraction fan. If you're staying in Las Vegas neither of those will be sufficient, you'd need 'real' air con, which is undermounted and very expensive. Source: used to use the Wave 2 now have an 11K BTU undermounted system

I used Ecoflow Wave 2 for a whole summer. Works pretty decently. The Wave 3 is even better

I tested it, and it's only really good for a specific set of people, like folks who want an easy, all-in-one off-grid heating/cooling solution and can afford it. Feel free to check out my serious, no-BS review if you want more details: [https://www.youtube.com/watch?v=f0SSbIZn45s](https://www.youtube.com/watch?v=f0SSbIZn45s)

I got mine a few weeks ago and I am struggling to see its worth, and very much contemplating returning it. It is set in a 2500 Sprinter Van, and I've got the vents connected, and it runs of the EcoFlow 5kw battery via the power hub, all that is fine. It just doesn't cool anything. I am testing it as we speak, it's been 1h, and the temperature inside the van is HOTTER than the temp outside (81F in the van, while it's about 70F outside). Wave 3 exhaust pipe is SO hot, I think it's solely responsible for heating up the space around it more than it's cooling it off. I am worried that if I take it anywhere actually hot, it won't do a thing. Maybe EcoFlow support can chime in?

Glad I could help. EcoFlow makes it nearly impossible to find this on their own website, but this what I use in the van. [https://us.ecoflow.com/products/power-kits-5kva-48v-power-system](https://us.ecoflow.com/products/power-kits-5kva-48v-power-system) We started with a 5kw battery, and while we used for 2-3 years, I thought it was not enough. I wanted second battery, just didn't want to spend the money, and didn't have enough space inside. However, once I connected the Alternator Charger cable, it is plenty of charge for us now. For reference, I have solar panels on the roof, doing about 200 watts per hour while we don't move. Alternator adds about 500 watts per hour while driving. You can crank up the current through the alternator to do about 800 watts, but I don't need it atm. We have a Starlink that consumes maybe 100-150 watts in peak performance, and a power hungry fridge that does another 50 to 200, depending on how hot it is. Between solar and driving our battery stays charged almost always. The only downside is cold nights; I have a diesel heater, but I prefer a quiet electric oil heater. Those can drain the battery 50% overnight easily. That's when I either drive around to recharger, or find a plugin site. All this to say that if you get only one 5kw battery, you will probably have enough, as long as you plan accordingly, and definitely use the alternator cord. The cord, by the way, connects to your van's 12V battery, and NOT to the alternator. The power kit then regulates current to make sure it all works together. Okay, hope that helps. p.s. I forgot to mention the obvious. Now that I am running a household AC in the van, it pulls a lot. 1kw at peak times, and then slows down. I also use it for the dog, when we leave her in the van. While it does drain the battery, the compromise seems fine to me. When I need the AC the most, the van stays in the sun, pulling solar, so at least part of the AC demand gets cancelled by the incoming charge.

It's ok. Cons - Its heavy and not that easy to setup/takedown. 2000wh is barely enough battery to get through a night (but I like to sleep cold like 68°). Needs to be sitting flat so It doesn't leak, need to drain it before moving or it will spill. Doesn't come with vent hose adapters you have to make your own with the template. Also the vent hoses aren't insulated. Pros - blows hard and creates a lot of air movement. Has a dehumidifier function that works well and also a strong heater (other AC units don't have either). You can control or monitor remotely. Uses ~525 watts on Max cool Uses ~270 watts when on a set temp. I'm not bothered by how loud or quiet it is. Seems normal volume to me.

Dont buy. They will send you a broken one. It will not cool or heat your space. Dont buy. A lot of people are complaing about this Wave 3. It is inferior. I wish I never bought it.

Have you checked out the EcoFlow Wave3? I just got it and I can use it without windows. Pricey but it is a 3 in 1 portable air conditioner so it makes it worth it.

I used it in a 15m² room with two ducts and very good insulation. \- The duct attachments leak (plastic on plastic with no seal): hot air from the air conditioner is blown into the room. \- The room temperature doesn't drop due to the first point. \- Drains every 2 hours with 55/60% humidity in the room. \- Louder than a large portable air conditioner (the noise is also more unpleasant to the ear). \- You have to be in front of the unit's fan to feel cool, but the airflow at full cooling power is very unpleasant. One of the worst purchases I've ever made.

You know what, l also checked ecoflow 2. l think ecoflow 3’s definitely a solid upgrade compared to the 2. The LFP battery lasts way longer (4000 cycles vs. 800), and it cools a bigger area with more power. ecoflow 3 feels like a proper step up for me I think.

I use my wave 3's for camping, to keep a couple roof top tents cool in the summer (we go over 100F often during the day. even at night it's hot a f mid summer here). I've been impressed with their performance, really. I had one die after its first use but since getting it replaced both of them are running well. For the most part. My use case for them is "overnight". If I'm camping, mid day, I don't mind the heat as long as I have shade and a cold drink. I really do not like sleeping while I'm pouring sweat. One thing I didn't like is that its battery just isn't anywhere near enough to run it overnight. At least not at a setting that is going to make any difference. Eco mode is just not enough, and would still come up short. Not really a fault of the wave 3, physics is physics. I also didn't like running a generator overnight while camping. I grabbed two 12v 100AH LFP batteries, wired them in series for 24v, and ran a XT60i cable from them to the wave 3 battery. Very cost effective solution imo to get 9-10 hours of non stop run time out of it. Even more run time if the compressor cycles. I needed to bump it up to 24v so the unit could get enough watts out of those batteries to keep up with the run time. Even at 24v, it falls just a little short. But it can pull enough out of them at 24v that they'll be the first battery to die, so I can get every watt possible out of them. I might be pulling like 5% or so out of the wave 3's battery with the rest from those external ones up until they die. Don't quote my numbers lol. It did necessitate another charger for those batteries, and of course I need a way to charge them the next day. But that's where I don't mind the generator. After I wake up I can run it for a couple/few hours to top them up and be ready for the next night. Best I can recall this was: cheaper than extending the run time with more ecoflow products, I end up with extra 12v 100ah batteries I could use for other things when I don't need them for the wave 3, if the wave 3 dies and ends up abandoned these batteries are still useful for other things.

I use a Wave 3 powered by a Delta 2 via the DC cable. The space being conditioned is half of a travel trailer, keeping the door to the other half closed helps a lot. Roughly 8'x15' and insulated for all-season RV life. Lately this time of day it is about 100 in the shade outside and 82 in here, but parked in the airflow I am cozy, even a bit chilled. yay! I use the Delta 2 because I don't have a Wave 3 battery, I have a Wave 2 battery which doesn't have the solar input. The original Wave 2 was faulty and returned under warranty, Ecoflow was kind enough to send me a new Wave 3 as a replacement. So, good on them. I'm on grid at the moment but I still rigged up a solar panel and fiddled with the Delta settings to where the panel provides roughly 20% of the power used. The downside: My Wave 3 has some jank. Regardless of if I am powering it straight from grid or from the Delta setup, sometimes it just stops cooling. Fans run, app says all is well, but compressor doesn't run at all until I unplug it for a minute or so. The app is screwy too, if I don't back out to the main menu every time I leave it then it refuses to respond when I return. Most jank of all is the drainage. According to Ecoflow tech support the drain pump can handle an unobstructed lift of 110cm. Mine would handle about 6" up and out the window for a day or so then start complaining with error 55 that it can't drain and stops cooling. So I put a 5-gallon water tote next to it and a little below the unit, mounted the drain hose to where it drained into the open air inside the tote. Sorta solved that, now it only throws the error and stops working for no good reason every three days or so. On the whole I wish I'd installed a wall-mount heat pump. This device is pretty neat on paper but the hassle has turned me off the brand.
