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 $390 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow DELTA 3 Plus holds 100% more energy (1024Wh vs 512Wh), so it runs the same load proportionally longer.
- EcoFlow DELTA 3 Plus has 1600W more surge headroom (3600W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 12.4 lb lighter (16.3 lb vs 28.7 lb).
EcoFlow DELTA 3 Plus
The DELTA 3 with a $100 premium for smart-home integration and faster UPS switching. Same battery, same surge.

Where it falls short:
- $100 more for features many buyers never use

Where it falls short:
- 512Wh is a single-day capacity
- No expansion
