Bluetti AC500 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 $1640 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC500 holds 500% more energy (3072Wh vs 512Wh), so it runs the same load proportionally longer.
- Bluetti AC500 has 8000W more surge headroom (10000W vs 2000W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 49.8 lb lighter (16.3 lb vs 66.1 lb).
- DJI Power 500 is rated for 4,000 cycles vs 3,500 — meaningful if you cycle it daily.
Bluetti AC500
A modular home-backup system, not a portable unit — the AC500 has no internal battery at all until you add B300K packs.
Best for: Serious home-backup builds where you're designing a system, not buying an appliance.
Where it falls short:
- Requires separate battery packs to function at all — budget accordingly
- Total system cost climbs fast
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
