Bluetti AC70 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 $140 less. Whether that gap is worth closing depends on what you need to run.
- Bluetti AC70 holds 50% more energy (768Wh vs 512Wh), so it runs the same load proportionally longer.
- DJI Power 500 is 5.7 lb lighter (16.3 lb vs 22 lb).
- DJI Power 500 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
Neither of these will start a sump pump or well pump — both surge below the ~3,400W those motors need. If home backup with pumps is your use case, look at higher-surge models instead of either of these.
768Wh with 1000W output at $499 — it does what the EcoFlow River 2 Pro does, with more output and more weight.
Best for: Campers who need to run a small fridge, not just charge devices.
Where it falls short:
- 22 lb — 5 lb heavier than the River 2 Pro
- Not expandable
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
