The differences that matter
- 1000 vs 800 W continuous → 200 W more headroom on what runs together.
- 512 vs 768 Wh at 7.3 vs 7.8 kg → half a kilo more carries 256 Wh more.
- Maximum charging 0.54 vs 0.94 kW, solar 300 vs 220 W → the second accepts more charging power, the first more from a panel.
- UPS in 20 ms vs EPS in 30 ms → when the mains drops, the first switches to battery faster.
Which one to choose
Choose DJI Power 500 if…
you plug in a load up to 1000 W or a panel up to 300 W, and want UPS mode for the switch to battery (20 ms declared). With 512 Wh, at 1000 W the battery lasts in theory about half an hour. It is rated at 25 dB.
Choose EcoFlow RIVER 2 Pro if…
you want more energy at the same weight, 768 Wh, with loads up to 800 W and a 1600 W peak, and charging at up to 0.94 kW. You accept 220 W of solar and a 30 ms gap when switching to battery (EPS).
