DJI Power 500 vs EcoFlow DELTA mini
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 DELTA mini holds 72% more energy (882Wh vs 512Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA mini has 100W more surge headroom (2100W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 7.3 lb lighter (16.3 lb vs 23.6 lb).
- DJI Power 500 uses LiFePO4 while the other uses NMC — roughly double the usable cycle life.
- DJI Power 500 is rated for 4,000 cycles vs 800 — meaningful if you cycle it daily.
If you plan to cycle the battery daily, think twice about the EcoFlow DELTA mini. Its NMC cells are rated for 800 cycles against the LiFePO4 rival's longer life — over years of regular use that's the more expensive unit, whatever the sticker says.
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
A compact NMC unit with a surprisingly strong 1,400W output for its size — but the 800-cycle battery means it won't age like the LiFePO4 field.
Best for: Buyers who want strong output in a light unit and won’t cycle it daily.
Where it falls short:
- NMC — ~800 cycles
- 2-year warranty, 300W solar input
