Technical comparison · Compact
Same 0.512 kWh capacity, same LFP cells and same 100 W USB-C: what decides is how much power comes out at the same moment, 1000 W against 500 W. Power figures are manufacturer-declared values.

How we assign awards →No awards in this tier.
The differences that matter
- Continuous output: 1000 W against 500 W (1000 W peak) → beyond 500 W continuous the RIVER 2 Max overloads, the DJI Power 500 does not.
- Solar input: 300 W against 220 W → with the DJI Power 500 the sun fills the battery faster.
- Grid charging: 0.54 kW against 0.66 kW → the RIVER 2 Max is full again sooner from the wall.
- Backup: UPS in 20 ms against EPS in 30 ms → only the DJI Power 500 follows it without restarting the loads.
Which one to choose
Choose DJI Power 500 if…
you have loads between 500 and 1000 W to run, with up to 300 W of panels, and you want the 20 ms UPS switchover in a blackout not to shut down what is plugged in. At 1000 W the battery lasts half an hour at most. The trade-off: 7.3 kg against 6.1 and grid charging that stops at 0.54 kW.
Choose EcoFlow RIVER 2 Max if…
500 W continuous is enough for lights, a laptop and a router, with a 1000 W peak for short surges, and you want 1.2 kg less to carry and grid charging at 0.66 kW. You accept 220 W of solar at most and a backup switchover with a gap (EPS, 30 ms).
