EF ECOFLOW WAVE 3 Portable Air Conditioner, 1800W/6100 BTU Cooling and 2000W/6800 BTU Heating, 1000W Fast Charging in 75 mins, 8H Wireless Running, APP Control, for Camping, Vanlife, RVs

The Ecoflow Wave 3 has thus far been impressive. It was nicely packed, and came with the appropriate cords, a duct template, a drainage hose, and an upgraded duct tubes with insulation. The installation was simple and straightforward. I opted not to purchase the extra battery (for now) to see if I could get away with just using my Deltas to power it up. I tested heating up my small room from 72F and brought it up to 81F in half an hour with an average of 360w-400w on my Delta 2 Max, which is impressive given my space heater uses 1.4kw. A must have accessory is the Wave 2/3 bag. It fits snugly with room for most of the accessories. Unfortunately it didn’t fit the hoses, but you could carry the Wave 3 itself, duct template, and cords. Not to mention it was only $25. I will be using this primarily to heat up or cool down my small room when I’m at home, or camping with my Overlandish tent or take it with me in my travel trailer. It’s light weight and versatile enough to do any. If it goes on sale later on down the road I may purchase another.

I recently purchased the Wave 3 and have been using it for a few weeks now. It has really exceeded my expectations. I own other EcoFlow devices as well and went ahead and bought the EcoFlow Extra Battery Cable and am using the EcoFlow Delta Max to power it and it is working perfectly. This setup has really changed the way I manage off-grid cooling for my small shop. The cooling performance is phenomenal for a portable unit. The Wave 3 drops the temperature impressively fast and maintains it without loud noise or clunky operation. I am very happy with it! The integration is also very nice and monitoring power consumption through the EcoFlow app is super convenient. This combo has been a huge win for me when it comes to portable cooling. The Wave 3 is a solid backup for unexpected heat waves. I’d definitely recommend it to anyone looking for a reliable, off-grid cooling solution for smaller spaces.

March 14, 2022 - After watching Will Prowse's two YouTube videos about the EcoFlow 600 (i.e., the River), both videos made about a year ago, I decided to buy 3 of them and three of the River Extra Batteries to go with them. However, just in case I discovered a problem, I initially ordered one River and one extra battery. It was good that I did because when I added the extra battery to the River it failed miserably. I had the same problems that Prowse encountered and he solved (to some degree) by a firmware update which was done via the EcoFlow App which he had downloaded to his phone. He had difficulty with the EcoFlow App in making that update, it took hours, but eventually he succeeded. I never crossed my mind that EcoFlow, knowing that a firmware update was necessary in order for the River to function properly with its extra battery, would send the River out without the update and, thus, in a defective condition. That would leave all of its buyers with a headache to have to deal with immediately after installation of the extra battery. Pretty inconsiderate thing for EoFlow to do. Here is what happened to me. I received the River and it seemed to work properly. I did not check to DC input (e.g., solar panel input) to verify its maximums as I figured it would be best to do that after I had received and installed the extra battery. I downloaded the EcoFlow app onto an Android phone using version 7.1.2. The app didn’t work. It recognized the River but would not connect to the internet which it had to do in order to effect any upgrade / update to the River. I viewed various YouTube videos on how to make such a connection but they were out-of-date. Nothing I tried worked. So the next morning, as soon as EcoFlow’ Customer Support Line was available (9am Eastern), I called. However, they were late manning their stations so I go a voice mail prompt. I did as it asked… left my name, my email address and my telephone number. The battery arrived a few days thereafter. I installed it and charged it up. Next I turned on the inverter, which had worked properly beforehand (as far as providing me with the UPS function, and that is when the problems began. The row of LED lights turned red and the River turned off the inverter. I went through a series of repeated tests, unplugging and replugging, turning the River off and then back on, and more but nothing helped. It was the same problem Prowse had encountered… the UPS function (power flow-through) would not work with the added extra battery. And there was no way I could update the firmware because the EcoFlow app did not work either. To make matters worse, the River would not recharge. After all of my testing the charge had dropped to 95% and it would not recharge. I used the River until the charge dropped to 92% but, still, it would not recharge. Again a series of tests but it simply would not recharge. It had been 5 days since I initially called EcoFlow and no one had contacted me. Again, I attempted to reach them by phone and this time I got a nice lady who asked me a series of questions in, what appeared to be, an attempt to diagnosis the problem. However, unless she had just begun to work at EcoFlow, she should have already known what the problem was. Prowse had informed them of it a year ago. Namely, the UPS function did not work with the added battery. She should have acknowledged an awareness of the problem and had a solution ready for me. She did not. So I ended the call before wasting any more time. I then separated the extra battery from the River and guess what. The River still would not recharge. Everything went back into its original boxes, I made a video tape to prove that all parts were being returned, then sent everything back to Amazon for a full refund. Conclusion: As I have already stated, there is evidence that EcoFLow is aware of the UPS problem and yet, apparently, they sold these devices in that defective condition anyway. They also know about the problem with their app (Version 2.7.0, Requires Android 5.0 and up) as it is complained about in many places (see the 2.0 rating out of 5.0 at Google Play). Consequently, because I smell unethical individuals at the top of the EcoFlow heap, I will not have any future dealings with them and suggest that others consider doing the same.

Amazing little device. I was looking for something versatile to cover multiple scenarios: RV living, and single room conditioning in my home. Using the central HVAC was causing massive energy bills, so I was looking for a solution to lower the cost. Enter EcoFlow's Wave 3 portable air conditioner/heat pump. I tried it in my large master bedroom, and it was able to bring my room to unbearably cold temperatures. Of course, I won't normally turn it that low, but the increase to 6100 cooling BTU is a massive improvement from its predecessor, the Wave 2. The heat pump function is efficient too, maxing out at only around 500w (compared to 1-1.5kw on traditional space heaters). It added some toastiness to a cold room, and with powerful fans, it was able to circulate the heat well. A few bonus features that surprised me were the auto shut-off timer and new pet care mode that let's you keep the device operating within a certain temperature to keep pets comfortable and safe. The drainage problem of the previous Wave 2 seems to have been fixed as well, and the new insulated hoses (as opposed to non-insulated ones for the Wave 2) do a much better job of not radiating heat into the room when undesired. Controlling the unit from the EcoFlow app is intuitive and full-featured too. Incredibly useful! But the physical buttons on the unit itself offer the majority of the functions with a nice, bright LED screen. Finally, the upgrade to the new LFP battery is a much welcome addition. NCM (Wave 2) only has 800 cycles before dropping to 80% capacity, but the LFP has 4,000 cycles before that happens. The new battery also comes with a carry handle, so it's more convenient. However, a nice touch is that both the W2/W3 batteries work with both W2/W3.

Three stars because it's just the unboxing/initial review. Its easy to set up and quick to charge. It's a little on the heavy side with the battery installed, but still of decent size and weight, considering. The cord wrap is a little clunky, but the initial quality is good. I haven't used it off-grid yet; Using it in my house as a test, in a 12W x 12L x 8H room, it cooled from 78° to 72° in about an hour. With that in mind, I'm sure that in my 8W x 10L x 4H tear drop, cooling would faster. I'm also interested to see how the dehumification function works. I'll post an update when I'm able to use it off grid to rate hooking up the hoses and the battery. I'll also post any tips or tricks I find to make it more efficient.

I've written a review for the River600, this will be strictly on the extra battery. If 288wh isn't enough, you can double your capacity for $200 extra (there's currently a $50 coupon) for a total of 576wh. With the extra battery, I was able to charge my iphone X 4 times, Macbook Pro 4 times, and various small devices like bike lights, speakers, flashlights, and camping ambiance LEDs over the course of a week. Divide that by half and you'll get your capacity w/out the extra battery. I was also able to use a power drill, tire inflator, and 600w (on/off) full sized home carpet vacuum for an hour w/ the extra battery during testing. Quick math, divide by 2. Its a fantastic option to be able to add this extra battery when you need the power, and remove it when you dont. It weighs just a couple of pounds, but you can disconnect it if you dont want to carry around the extra weight. Removal takes just a couple minutes, but its not the smoothest. It requires 4 screws be removed, and a cover replaced - really easy but I would prefer a quick release. CONCLUSION Well worth the price for the flexibility of being able to bring along the extra power when you need, and leave home when you dont. Its easy enough to attach/detach but a quick release would have been appreciated. Overall, for $200 extra its one of the best mobile power stations on the market.

The EcoFlow Wave 3 packs a serious punch when it comes to portable climate control. Here are its standout features: • Dual Functionality: It’s both an air conditioner and a heater, delivering 6100 BTU of cooling and 6800 BTU of heating— enough to change the temperature by 15–17°F in just 15 minutes. • Multiple Power Options: You can run it via standard AC power, EcoFlow’s lithium battery, solar panels, or even your car’s power outlet, making it incredibly versatile for off-grid use. • Smart App Control: The EcoFlow app lets you control temperature, modes, and even get water drain alerts remotely. • Dehumidifier & Pet Care Modes: It includes a dehumidification function and a pet care mode that automatically cools when temps rise above a set threshold. • Quiet Operation: Sleep mode runs at just 44 dB—about as loud as a quiet conversation—so it won’t disturb your rest. • Long Runtime: With the optional 1024Wh battery, it can run wirelessly for up to 8 hours in Eco Mode. • Fast Charging: The optional battery can be fully recharged in about 77 minutes via AC current or 3 hours with solar. • With insulation it can cool about 120-180 sq.ft. room. This in my opinion is one of Ecoflow’s better implementation. It is expensive when compared to other window air conditioners/heater combinations, but it is light weight (about 40 lbs.) compared to other heavy air conditioners, and for tent camping, it is beneficial for a good night’s sleep when temperatures are in the high 80s or 90s.

Why did you pick this product vs others?: Researched heavily. I have worked in the HVAC industry. I am certified. I actually saw a utube where the guy took a wave 2 apart. It’s a mini Heat pump which means it can do heat or cool. This unit does what it’s supposed to do. I have seen complaints about cooking tents in 100 degree or more. Rule of thumb. No matter the situation an efficient system can only cool 20 degrees lower than ambient. That’s the best scenario is if it’s 90. Then maybe 70. But tents are not insulated. So it’s all about directed air to keep you comfortable. This machine is incredible. It cost a ton with the battery but the battery is LifePo4. Well worth it
