UGREEN PowerRoam 1200 vs Anker 535 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 535 PowerHouse costs $370 less. Whether that gap is worth closing depends on what you need to run.
- UGREEN PowerRoam 1200 holds 100% more energy (1024Wh vs 512Wh), so it runs the same load proportionally longer.
- UGREEN PowerRoam 1200 has 1750W more surge headroom (2500W vs 750W) — that decides whether a fridge, pump or AC compressor will actually start.
- Anker 535 PowerHouse is 9.8 lb lighter (16.7 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 durable half-kWh unit for devices and light loads. Dependable, but the low output and slow charging make it a device-first companion.
Best for: Campers charging phones, laptops and lights, not appliances.
Where it falls short:
- 500W output is device-scale
- 120W solar input, slow recharge
