UGREEN PowerRoam 600 vs Growatt VITA 550
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
These two cost the same, so the decision comes down to what you're powering.
- UGREEN PowerRoam 600 holds 26% more energy (680Wh vs 538Wh), so it runs the same load proportionally longer.
- UGREEN PowerRoam 600 has 300W more surge headroom (1500W vs 1200W) — that decides whether a fridge, pump or AC compressor will actually start.
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 tidy half-kWh unit with fast charging and a 1,200W surge that lets it start small appliances a 600W rating wouldn't suggest.
Best for: Campers who want fast charging and a bit of surge headroom at half a kWh.
Where it falls short:
- 538Wh is weekend-scale
- 3-year warranty
