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 $740 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Max holds 300% more energy (2048Wh vs 512Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Max has 2800W more surge headroom (4800W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 38.8 lb lighter (16.3 lb vs 55.1 lb).
EcoFlow DELTA 3 Max
The value leader in the 2kWh class. Same 4800W surge as the DELTA 2 Max at $500 less, with 1000 more cycles.
Best for: Home backup buyers who want compressor-starting surge without paying flagship prices.
Where it falls short:
- 55 lb is a two-hand lift
- Only marginally lighter than heavier rivals
DJI Power 500
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
