EcoFlow WAVE 3 Add-on Battery · 1024 Wh

Keep WAVE 3 mobile. This dedicated 1024 Wh LFP battery lets the compatible WAVE 3 air conditioner work away from a wall socket. It is a separate climate-control accessory, with USB charging available for smaller compatible devices.

Useful energy, clearly defined

• 1024 Wh LFP battery capacity.
• USB-C output up to 140 W and USB-A up to 18 W.
• Dedicated connection to the WAVE 3 unit, which is sold separately.

EcoFlow quotes approximately 2–8 hours for WAVE 3 operation with an add-on battery, depending on mode and conditions. This is not a promise of eight hours at full cooling power. Ambient temperature, room size and settings matter.

This is not a DELTA/RIVER expansion battery and does not provide standalone 230 V AC outlets for studio tools.
