ECOFLOW WAVE 2 Portable Air Conditioner, 5100BTUs of Cooling, 6100BTUs of Heating, Add-On Battery, Control with App, No Drainage Required, for Outdoor Camping/RVs or Home Use(Battery Not Included)

Product Information

Both of these ports will run without the WAVE 2 connected, giving you the option of charging up and toting around a 1KW monster battery for keeping your laptop and phone topped up even when you don’t need heating or cooling. It is also rated for dust and water resistance at IP65, though the Wave 2 itself only has an IPX4 rating, meaning it can withstand splashes but is not waterproof, so you need to be careful using it outside.

To be clear I’m completely ignoring the relatively cheap, single-hose AC units that are readily available in the UK. This is- I’m told- not the most efficient way to run the AC, but even on Eco it managed to make things liveable. and raise 10°C from 20°C in 5 minutes for 10m³ with 1,800W (6100 BTU/hrs) of heating in optimal running performance. I did have trouble charging a 2016 MacBook Pro and a 2022 MacBook Air, however, with them entering a constant loop of charging/stopping. Just before 12:00 I angled the hose up slightly to circulate air again, and the ambient temperature dropped to around 19c.

I’m going to preface this entire review with one simple caveat: I am only testing the WAVE 2’s cooling potential.

Charge fast, at home or on the go: WAVE 2—the ultimate air conditioner and heater that comes with a swappable battery! With its upgraded LFP battery chemistry, DELTA 2 Max has a lifespan of 3000 complete cycles until it reduces to 80% capacity.You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. EocFlow’s documentation claims it will take around 3000 cycles to drop to 80% capacity and the battery itself – perhaps unsurprisingly since it doesn’t have any fans, inlets or outlets – has a slightly better ingress protection rating than WAVE 2, citing IP65. Simply unbox, follow the step-by-step instructions in the user manual (which takes less than ten minutes), and enjoy the refreshing coolness or comforting warmth. Draining the unit with the battery attached is tricky, since it brings the total weight from a modest 14kg up to over 20kg, and separating the two without unleashing the water is similarly difficult. It wasn’t until the battery ran flat and I turned the AC off – bear in mind my office is quite small and not well insulated – that I saw that this temperature range was a fair slice out of the day’s high.

If you’re travelling it’s a different story- the WAVE 2’s add-on battery is super compact and luggable compared to its larger, power-station counterparts- but if you don’t need maximum portability (constant use in an RV for example) you would probably be better off with a standalone power station. If portability is a must, and you can afford it, then the versatile Wave 2 should be on your short list. Indeed if you want to vent out of a window it’s not just blocking up the open window area you’ll need to take into account, but how you’ll block out the enduring daylight of summer too. EcoFlow's tailor-made compressor enables WAVE 2 to provide 1,495W (5100 BTU/hrs) of cooling and 1,800W (6100 BTU/hrs) of heating.If you have larger rooms or those that get much hotter, you’ll need to up the BTU count on a unit and get something larger, such as a more traditional portable unit. Once you arrive at your destination, simply unfold it and use it as a kickstand to get your sun exposure just right. No drainage is needed in cooling mode when humidity is below 70%, but it is still needed in heating mode.
