UGREEN PowerRoam 1200 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 $550 less. Whether that gap is worth closing depends on what you need to run.
- UGREEN PowerRoam 1200 holds 300% more energy (1024Wh vs 256Wh), so it runs the same load proportionally longer.
- UGREEN PowerRoam 1200 has 2200W more surge headroom (2500W vs 300W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 521 PowerHouse is 18.3 lb lighter (8.2 lb vs 26.5 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.
A well-rounded 1kWh with an unusually high 1,000W solar input for its price — it recharges off panels faster than most rivals in the class.
Best for: Off-grid campers who prioritise fast solar recharging at 1kWh.
Where it falls short:
- 1,200W output trails the 1,800W class leaders
- Not expandable
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
