EcoFlow WAVE 3 Add-On Battery

The EcoFlow WAVE 3 Add-On Battery gives you true wireless comfort wherever you set up. Designed to pair with the EcoFlow WAVE 3 portable air conditioner, this add-on battery unlocks cord-free cooling and heating for campers, vans, tents, cabins, boats, and mobile workspaces.

With 6100 BTU cooling and 6800 BTU heating, the WAVE 3 system keeps you comfortable year-round — whether you’re cooling down a van on a summer trip or taking the chill out of a workspace on a cold Irish morning. Fast performance means noticeable temperature drops in as little as 15 minutes.

Once connected, the add-on battery delivers up to 8 hours of wireless operation, so you’re not tied to mains power. Charging is flexible too, with multiple options available through the WAVE 3 system, making it easy to stay powered on the road or off-grid.

Setup is simple thanks to the insulated exhaust duct, designed to work across a wide range of outdoor and temporary setups. Control everything easily using the EcoFlow app, with one-tap adjustments straight from your phone.

Backed by a 2-year warranty, the EcoFlow WAVE 3 Add-On Battery is the finishing piece that turns WAVE 3 into a fully portable, all-season climate solution.

Note: EcoFlow WAVE 3 portable air conditioner sold separately.
