I think the AC unit is excellent . Cools and heats incredibly well and very small. The battery though, was very poorly optimized . When charging the battery, there is about a 20watt energy leak. In other words, if u have a 100 watt charger it's only gonna charge at 80 watts, the remaining 20w just disappears. This makes using solar charging extremely inefficient . You also can't charge the battery directly, it must be charged through the AC unit. I'm guessing my 20w is used to pass the power from the AC to the battery. Why not just charge the battery directly ???? Minus 2 stars because the battery isn't cheap at nearly 850 dollars I can buy a jackery bank to power the AC unit directly and solar charge the jackery battery... Edit: ecoflow contacted me and offered a refund for the battery. I will update this when the transaction has been completed . Edit: They offered a refund and as soon as I sent them the serial number they stopped replying. Edit: I had return issues on my end that prevented me from completing the return. Because the customer service was excellent Ill give 5 stars for being accomidating with all of my issues. And offering a return even past the return window. Thank you ecoflow . ... show more

    • Garbage, waste of money.

I've tried this thing in the heat to cool down, and it was useless. I also used the heater option in colder climates, it barley makes a difference in temperature. The battery lasts 4 hours on a full charge. What a waste of money.

    • A lot of cool with minimal noise
I have Wave1, EcoFlow Pro 2000 Max, River Pro 2 and Glacier Frig, i.e. I am invested in EcoFlow. My goal is transportable power: in my house for outages, in my RV and the frig/River sometimes in my Jeep. The Wave2 and extra battery work flawlessly for me. I have not tried heat but have been running the A/C in my home. It is cooling a 10 x 15 room as well as partially cooling and adjacent 10x10 via a helper fan. I am in NW MT so very low humidity. Today it hit 95 with 18% humidity so "feels like" is 92. In my house (older moderately insulated but new windows), I was able to held 68-72 max. Like all EF products, the app functionality is excellent. ... show more

    • Very disappointing performance, bulky and heavy. Can't even run well when plugged in. UPDATE BELOW
We purchased this as a heater/AC for overlanding. We decided to take it out for a test run last weekend, but thankfully I was cautious about bringing this as our only heat source during winter camping, and so we brought another small 750W space heater. We also decided to go to one of the few campgrounds in our state that have shore power available so we could plug in if needed. We initially tried to set this up in our iKamper Skycamp Annex which was attached to the rooftop tent on our Electric Vehicle (plugged in to shore power). The temp was about 41 degrees when we first fired it up. it could not heat the air at all, and wouldn't even blow any air output from the vent. I had read somewhere that since this was a heat exchanger, it wouldn't work once the temp was below 40F (already a serious limitation for overlanding, but whatever...). So I thought that perhaps if I blew warm air from the small 750W space heater into one of the air intakes, that might allow it to then get up to temp and start warming the air in the annex, and once that air began to warm, it should continue to recirculate and further warm the previously warmed air. I had the cool air side of the heat exchanger vented to outside the annex. So I hooked it all up, and low and behold, it worked! It started pumping out some heat and we thought our fears of a very cold night were about to be resolved. Never mind that we were using a plugged-in $18 Amazon-basics space heater to heat the air going into our $1482 fancy-pants Ecoflow Wave, we were just happy to have some heat! All was going well for about 2h until just before we retired up to the rooftop tent. My plan had been to direct the heat from the Ecoflow into the RTT with the included duct tubing. But before I could hook it up, I noticed the air from the heated vent beginning to cool. I checked the app, and sure enough the heat was falling precipitously, and within about 10 minutes it was pumping out air that was COLDER than the air intake, which I just don't understand. To ensure that we wouldn’t run out of juice in the middle of the night, we had previously plugged the Ecoflow into shore power since it was very rapidly depleting the attached battery (which, as an aside, makes this unit even heavier than it already is). We were very frustrated and disappointed by this point and decided we'd better get up into the rooftop tent and into our down bedding before the temp in the annex dropped even further. We 'carefully' brought the small electric space heater up with us as well, to take the chill of of the RTT before we called it light's out. We had to be very careful to keep all of the down bedding away from the heater (which is why we had purchased the dang Ecoflow in the first place!) The next morning (after a cold night with lots of condensation in the RTT) I had an epiphany that the heat exchanger must be icing up, leading it to stop warming after a period of time. I thought that perhaps if I put the Ecoflow Wave into my vehicle, and then warmed the vehicle, I could then run the Wave to pump air through the ducts and into my annex and ultimately the RTT. Since the vehicle is an EV, I could turn on the heaters and actually could keep the interior of the vehicle at 77 degrees. The Wave then really only had to warm it up a bit further and then pump that warm air out and into the tent spaces. Again, it worked initially, and my wife thought I was brilliant (even though we were now heating an entire vehicle to 70-80 degrees just to get our fancy pants heater to just warm the tent up to about 55 degrees...). But just as with the prior night, it only worked for a couple hours and then started blowing very cold air (colder than the in-vehicle temp). If I then shut it off for a few minutes and turned it back on, it would begin heating and would get the air output temp up to >120F. That would only last for a brief period of time, then it would again fall and pump out cold air. Our second night of camping, we had strong winds and snow, and I woke up about every 90min to 2h all night long to check the temp inside the vehicle, and to turn off and then turn back on the Wave to try to get it to actually generate heat. Overall, very miserable experience and terrible performance. And if that isn't bad enough, did I mention that this thing is super bulky, very fragile (so much so that I had to transport it in it's original box for fear of breaking it in the back of the SUV), and ridiculously heavy to move around. In addition, even though the weather was in no way cooperative enough to break out our solar panels, I noticed that there is no way to independently charge the Wave battery without it being attached to the Wave main device. What?!? This means you have to break down your whole vent tubing set up and lug this entire beast to whereever your solar panels happen to be in order to get reasonable sunshine. Completely ridiculous. Cmon, Ecoflow. I really thought you had this "ecosystem" figured out, which is what sold me on the Wave, the Delta 2, and the Glacier fridge. But after this experience, i wish I would have done more research and not trusted some of the initial reviews. I will post separate reviews for the Delta 2 (which I am pretty impressed with) as well as the Glacier Fridge (which I mostly like, except it has the same lame limitation as the Wave, in that you cannot charge the battery from solar panels when it is not in the fridge...again this means you have to lug the whole heavy fridge out to whereever the sun and solar panels are) Suffice to say, this might be an ok device in a home as a very expensive space heater, but it has no business anywhere else. UPDATE 1/22/24: While I stand behind the limitations described in the above review, I do feel that I should commend EcoFlow for reaching out to me after I posted it. They apologized for my poor experience and offered me a full refund for the Wave 2 and add-on battery. They sent prepaid shipping labels and I put everything back into the original packaging, added the labels, and called FedEx who picked the items up from my front door. Very seamless return experience. All that EcoFlow asked was that I hopefully give them a chance again in the future, which I most certainly will now. As I mentioned above, the Delta 2 and Glacier fridge that I purchased at the same time are both really nice, with seamless apps. Tried out the freezer side of the fridge last night by hauling 4 pints of icecream on a 2h road trip to the cabin, and the freezer was, amazingly, reading -2 degrees F interior temp! So EcoFlow, here is my request for the 'future' Wave 3: Smaller and lighter, somehow. Allow the add-on battery to be detached and independently charged (by 12v DC, solar, or regular 110v AC) without having to be connected to the Wave 3. Beef up the delicate air intake and output fins, as these seem highly likely to get broken on the current model. Please provide TWO of the smaller sized 'exhaust duct D" accordion vent tubings so that the cold and warm air can be independently diverted to the intended locations. The device really needs to function down to at least 20 degrees F to be worthwhile as a camping/overlanding product. The whole setup, with battery attached, and including ductwork, needs a padded, reinforced travel bag or case with handles to allow for protection during transport and setup in the back of an SUV or truck bed. Alternatively, a padded travel case for the Wave 3 and battery, with a separate case for accessories, could work. They just both need to provide some solid protection for this expensive investment. And of course most importantly, the Wave needs to be able to maintain heat output for as long as the battery holds, or indefinitely when hooked up to wall or shore power. Mine would briefly get up to almost 130 degrees F, which seemed like a bit of overkill. I wonder if it maxxed out at 100 degrees F, then it might not freeze up and shut down so much. Just a thought. Should you be looking for a beta tester for your next version, I'd be happy to provide you fair and objective feedback. Trust me, I want you to be successful with this product because I really want one! Thanks EcoFlow! ... show more

    • AC is not cold even in a small Scout Yoho truck bed camper.
I owned 2 of your products: 1) 2023 Ecoflow river 2: I bought it last month. This unit made a loud noise when connecting to a 100w/120v heater blanket (the unit is full charge and with the newest firmware). Called their customer service team (properly 1-2 members total in the team - keep talking to the same guy) to address the issue, the problem is still unsolved. 2) 2023 Ecoflow Wave 2 AC/heater with external battery pack: I use this unit for my little Scout camper (Yoho model).

    • A battery powered a/c that actually works!
Review Image by D. Loughran D. Loughran
When paired with the Ecoflow app, this a/c works great! You need a drain bucket (enable auto-drain in the app) to keep chilling, but with this feature on, it will keep you cool. Already having power outages in Texas, but the Ecoflow kept our bedroom cool during a five hour power loss; mine has the battery, essential if you ask me. Has the cooling ability of much larger units. I had previously purchased the Zero Breeze Mark I and II; there is no comparison! The Ecoflow is the one to get! The battery arrives in a separate delivery, so don’t worry if its not in the a/c delivery. ... show more
