UGREEN PowerRoam 600 vs Anker 521 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
Anker 521 PowerHouse costs $150 less. Whether that gap is worth closing depends on what you need to run.
- UGREEN PowerRoam 600 holds 166% more energy (680Wh vs 256Wh), so it runs the same load proportionally longer.
- UGREEN PowerRoam 600 has 1200W more surge headroom (1500W vs 300W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 521 PowerHouse is 9.4 lb lighter (8.2 lb vs 17.6 lb).
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.
UGREEN's entry unit punches slightly above its output class thanks to a 1,500W surge, but 600W of continuous power keeps it in device-and-small-appliance territory.
Best for: Campers who want a fast-charging sub-1kWh unit from a mainstream electronics brand.
Where it falls short:
- 600W output rules out heaters and compressors
- 680Wh is weekend-scale
A pocket-scale LiFePO4 unit for keeping devices alive. 200W of output means it's a charger, not an appliance station.
Best for: Travelers and campers topping up phones, cameras and a laptop.
Where it falls short:
- 200W output runs devices only
- 256Wh is small
