How long does the Wave 3 run on its battery?

EcoFlow rates the 1024Wh add-on battery for up to several hours of runtime in battery mode. Actual time depends on cooling or heating mode, fan speed and ambient temperature, so expect the shortest runs in high heat.

How large a space can the Wave 3 cool?

The listed maximum coverage is about 107 square feet, roughly a small bedroom, tent or van interior. It is not a substitute for a window or split unit in a large room.

Does the Wave 3 heat as well as cool?

Yes. It is a heat pump with 6,100 BTU cooling and 6,800 BTU heating, plus a sleep mode. That makes it usable in cold weather, not just summer.

What comes in the bundle?

The box includes the Wave 3 air conditioner, the Wave 3 add-on battery, a battery connection cable, charging cables and user documentation. You need both parts for cordless operation.

Is $1,369 a good price for the Wave 3 with battery?

It is the best new price among the three stores listing it as of November 8, 2026. Because the bundle is a niche product with few sellers, compare against the unit-only price plus a separate battery before deciding.

Can I use the Wave 3 while it charges?

Yes. The unit runs on mains power or on the add-on battery, so you can use it plugged in and switch to battery when power is unavailable.
