EcoFlow RIVER 2 Pro vs DJI Power 500
Side-by-side on the specs that decide it — surge, capacity, runtime and price.
Both models' specs verified against manufacturer listings · Last updated
The short answer
DJI Power 500 costs $240 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow RIVER 2 Pro holds 50% more energy (768Wh vs 512Wh), so it runs the same load proportionally longer.
- DJI Power 500 has 400W more surge headroom (2000W vs 1600W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 0.7 lb lighter (16.3 lb vs 17 lb).
- DJI Power 500 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
The one you actually carry. At 17 lb it is light enough for one hand, yet unlike the true pocket units it has the 800W of output needed to run small appliances rather than just charge devices.
Best for: Backpackers, photographers and festival-goers who care about weight above all.
Where it falls short:
- 800W output limits you to electronics and small loads
- 220W solar input means slow off-grid top-ups
The smaller DJI unit: 512Wh and 1,000W make it a capable weekend companion, with fast charging and low noise as the standouts.
Best for: Weekend campers and creators who want a light, fast-charging half-kWh unit.
Where it falls short:
- 512Wh is a single-day capacity
- No expansion
