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 $3340 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro 3 holds 700% more energy (4096Wh vs 512Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro 3 has 6000W more surge headroom (8000W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 96.7 lb lighter (16.3 lb vs 113 lb).
EcoFlow DELTA Pro 3
The most complete large unit here. 4096Wh, 4000W, 8000W surge and 2600W of solar — it does everything the F3800 does with less weight.
Best for: Whole-home backup buyers who want maximum solar recharge speed.
Where it falls short:
- $3,699 is a serious investment
- Overkill unless you're backing up a whole home
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
