DJI Power 500 vs Anker 555 PowerHouse
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 $340 less. Whether that gap is worth closing depends on what you need to run.
- Anker 555 PowerHouse holds 100% more energy (1024Wh vs 512Wh), so it runs the same load proportionally longer.
- DJI Power 500 has 500W more surge headroom (2000W vs 1500W) — that decides whether a fridge, pump or AC compressor will actually start.
- DJI Power 500 is 13.6 lb lighter (16.3 lb vs 29.9 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.
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
A 1kWh unit whose 1,000W output and slow charging show its age — the newer, cheaper Anker C1000 beats it on nearly every axis.
Best for: Only worth it steeply discounted against the C1000.
Where it falls short:
- 1,500W surge is low
- 200W solar input and a slow 138-minute recharge
