About this product

The EcoFlow DELTA 3 Max puts 2,048Wh of LiFePO4 capacity and 2,400W of 120V output in a package 13% lighter than EcoFlow's previous 2kWh model. With a sub-10 ms auto-switch, quiet operation and multiple ways to recharge, it is a dependable backup for refrigerators, medical devices, home offices and satellite communications gear, at home or on the road.
