Growatt INFINITY 1500 vs UGREEN PowerRoam 600
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
UGREEN PowerRoam 600 costs $700 less. Whether that gap is worth closing depends on what you need to run.
- Growatt INFINITY 1500 holds 122% more energy (1512Wh vs 680Wh), so it runs the same load proportionally longer.
- Growatt INFINITY 1500 has 1500W more surge headroom (3000W vs 1500W) — that decides whether a fridge, pump or AC compressor will actually start.
- UGREEN PowerRoam 600 is 19.9 lb lighter (17.6 lb vs 37.5 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 capable mid-size that flies under the radar. Solid 2,000W output and fast charging, let down mainly by a shorter warranty than the big brands.
Best for: Value hunters who want 1.5kWh and don't need the longest warranty.
Where it falls short:
- 3,000W surge is modest for the output
- 3-year warranty vs 5 from the majors
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
