EcoFlow DELTA 2 Max 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 $1240 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 2 Max holds 300% more energy (2048Wh vs 512Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 2 Max has 2800W more surge headroom (4800W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 33.7 lb lighter (16.3 lb vs 50 lb).
- DJI Power 500 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
The surge sleeper. At 4800W it starts loads that stations twice its price can't — and most spec sheets bury that number behind the X-Boost figure.
Best for: Home backup where something with a compressor — fridge, freezer, window AC — has to start reliably.
Where it falls short:
- 50 lb is heavy for its capacity
- Marketing leads with the 3400W X-Boost number, which understates it
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
