Our take on the EF ECOFLOW Wave 2 Portable Air Conditioner With Add-on Battery
The EcoFlow Wave 2 is a portable air conditioner that runs on battery power as well as mains, so it can cool a tent, van or room without a fixed outlet. The add-on battery extends runtime well beyond a single charge and can be topped up from solar, a car or a wall socket. It cools and heats, which most portable AC rivals do not, but it is heavy and its cooling output suits a small space rather than a whole room. Owners like the off-grid flexibility and the app control; critics point to the weight, the fan noise and the need for the extra battery to get useful runtime.
- Runs on its own battery, not just a wall outlet
- Cools and heats in one unit
- Charges from solar, car or mains
- App and voice control
- Add-on battery extends runtime

Questions and answers
- Does the Wave 2 need the add-on battery to run?
- No. It runs from a wall outlet on its own. The add-on battery lets it run without mains power and extends runtime off-grid.
- Can it be charged from solar panels?
- Yes. EcoFlow supports solar charging through its solar input, as well as car and mains charging.
- Does it heat as well as cool?
- Yes. The Wave 2 has a heating mode in addition to cooling, which sets it apart from most portable AC units.
- How large a space can it cool?
- It is built for small spaces such as tents, vans and single rooms, not whole homes. Expect it to struggle in large or open areas.
- Does it need draining?
- In humid conditions it collects water and needs draining. EcoFlow offers a drainage option for continuous operation.
- Is the add-on battery worth it?
- If you plan to run it away from an outlet, yes. Without it, runtime on battery alone is short.
