EcoFlow DELTA 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 $2840 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA Pro holds 603% more energy (3600Wh vs 512Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA Pro has 5200W more surge headroom (7200W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 82.7 lb lighter (16.3 lb vs 99 lb).
- DJI Power 500 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
EcoFlow DELTA Pro
The previous-generation flagship, now mostly worth buying on discount. The Pro 3 beats it on nearly every axis.
Best for: Bargain hunters who find it steeply discounted against the Pro 3.
Where it falls short:
- 99 lb and 165-minute recharge — both beaten by the Pro 3
- Aging platform; expect it to be phased out
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
