EcoFlow DELTA 3 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 $290 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 holds 100% more energy (1024Wh vs 512Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 has 1600W more surge headroom (3600W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 12.4 lb lighter (16.3 lb vs 28.7 lb).
EcoFlow DELTA 3
The 1kWh class got a serious upgrade here. 3600W surge at $649 beats the older DELTA 2 on every axis that matters.
Best for: Anyone about to buy a DELTA 2 — this is the same money for materially better specs.
Where it falls short:
- Still only 1024Wh
- Solar input unchanged at 500W
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
