The Owner's Insights on the EcoFlow WAVE 3 Portable Air Conditioner
This is air conditioning you carry rather than install. No hole in your roof, no wiring, nothing bolted on. It's 15.3kg and 519 x 297 x 336mm, so it goes in the tent, the swag, the truck cab or the boat and comes out again.
The output is real: 1,800W of cooling and 2,000W of heating, which is 6,100 and 6,800 BTU. That's a small room, a tent or a cab, not a whole caravan. Size your expectations to the space you're actually cooling.
It runs on mains or DC, and with an add-on battery you get 2 to 8 hours off-grid depending on how hard it's working. Down at 44 dB on low it's quiet enough to sleep beside.
Why You'll Love the EcoFlow WAVE 3 Portable Air Conditioner
- 1,800W cooling, 2,000W heating. 6,100 and 6,800 BTU, so it works both ways.
- Carry it, don't install it. No roof hole, no wiring, no fitter needed.
- 15.3kg. One person moves it from the ute to the tent.
- 44 dB on low. Quiet enough to sleep next to in a tent.
- Runs on AC or DC. Mains, a power station, or your vehicle's alternator.
- 2 to 8 hours on a battery. With the add-on battery, off-grid without mains.
- Dehumidification mode. Takes the sting out of a muggy night up north.
- WiFi and Bluetooth app. Set it from your sleeping bag, not the floor.

What 6,100 BTU will and won't cool
Six thousand BTU is a small space: a tent, a swag, a truck cab, a boat cabin or a single room. It's not a caravan air conditioner and it won't cool a whole van on a 38 degree afternoon. Where it does work brilliantly is the thing a rooftop unit can't do, which is cooling a space that has no air conditioning at all and no way to fit one. Match it to the volume you're actually trying to cool and it'll do the job.
Why portable beats installed, sometimes
A rooftop unit means cutting your ceiling, 40-odd kilos up high and a fitter's bill. This means picking it up and putting it where you need it. In a tent this week, the boat next week, the shed after that. If you camp in a swag or a tent, or you want cooling in more than one place, there is no installed unit that competes. If you've got one van and it stays a van, an installed unit is more efficient and more permanent.
Running it off-grid
Rated cooling power is 690W on AC and 640W on DC. With EcoFlow's add-on battery you get 2 to 8 hours depending on the setting and the heat. Off a power station, you'll want something that holds 700W comfortably and has the capacity to back it: a 2,000Wh station running it at 640W gives you roughly three hours flat out. Have a look at the power station range if you're building that side of it.
Ducting matters more than people expect
Every portable air conditioner has to put the heat somewhere. That means running the exhaust duct out of the space you're cooling, whether that's a tent window, a vent or a cracked door. If the hot air stays in the room, you're heating it as fast as you're cooling it. Set the duct up properly the first time and this works. Skip it and you'll wonder why it isn't doing much.
Heating as well as cooling
It does 2,000W of heating, which is more than it cools, and that makes it genuinely useful in winter as well. A tent at 5am in the high country is exactly where a 2,000W heater earns its keep. It runs down to 5 degrees ambient, so alpine mornings are within range. That two-season use is what makes it worth carrying rather than a summer-only piece of kit.
What's Included
- EcoFlow WAVE 3 portable air conditioner
- Exhaust duct and adapters
- AC power cable
- DC power cable
What's Not Included
- The EcoFlow add-on battery
- A power station
- A tent or window kit for your specific setup
The ducting and both power cables come with it. The add-on battery is separate, and that's what turns it from a mains-powered unit into a genuinely off-grid one, so factor it in if that's how you'll use it.
Not Sure Which Portable Air Conditioner Suits You?
The WAVE 3 suits you if you want cooling in a tent, a cab, a boat or a room where nothing can be installed, and you don't mind running ducting. It's the wrong pick if you're cooling a whole caravan on a hot afternoon, where a rooftop unit has three times the capacity. Not sure it'll cool your space?
