DJI Power 500 vs EcoFlow DELTA 1300
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 $640 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 1300 holds 146% more energy (1260Wh vs 512Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 1300 has 1300W more surge headroom (3300W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 14.6 lb lighter (16.3 lb vs 30.9 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 1300. 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
The original DELTA that put EcoFlow on the map. Fast-charging and high-surge for its day, but the NMC battery and lack of USB-C now show its age.
Best for: Bargain hunters who find it heavily discounted.
Where it falls short:
- NMC — ~800 cycles
- No USB-C PD
- 2-year warranty
