Summary
The EcoFlow DELTA 2 pairs a 1,024Wh LFP battery with an 1,800W continuous output and fast 1,200W AC recharging (full in about 80 minutes). It supports one extra battery and connects to the EcoFlow app over Wi-Fi and Bluetooth. It is an older model; EcoFlow’s US store appears to have replaced its product page with the DELTA 3.
