EcoFlow WAVE 3 Portable Air Conditioner Add-on Battery

The EcoFlow WAVE 3 Add-on Battery extends your WAVE 3 portable air conditioner's runtime for true off-grid comfort, with up to 8 hours of wireless cooling or heating in Eco mode. This 1024Wh LFP battery clicks directly into the base of the WAVE 3 for cordless operation, with no wall outlet or generator required. Built on lithium iron phosphate cells, it holds 80% capacity after 4000 cycles, close to a decade of seasonal use. Recharge is fast and flexible: a full charge in around 75 minutes using combined AC and XT60 input, plus support for solar (up to 400W) and car charging. An IP65-rated enclosure resists dust and water for rugged outdoor use, while built-in USB-A and USB-C ports charge your devices on the go. Monitor charge level and battery health any time through the EcoFlow app. Ideal for camping, caravans, four-wheel driving and blackout backup.
