Anker SOLIX F3800 vs UGREEN PowerRoam 2000
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 2000 costs $2700 less. Whether that gap is worth closing depends on what you need to run.
- Anker SOLIX F3800 holds 88% more energy (3840Wh vs 2048Wh), so it runs the same load proportionally longer.
- Anker SOLIX F3800 has 5400W more surge headroom (9000W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- UGREEN PowerRoam 2000 is 77.3 lb lighter (55 lb vs 132.3 lb).
- Anker SOLIX F3800 is rated for 4,000 cycles vs 3,000 — meaningful if you cycle it daily.
This is where portable power stops being portable and starts replacing a standby generator. The 240V split-phase output is the headline feature.
Best for: Whole-home backup where you need 240V loads and can't run a gas generator.
Where it falls short:
- 132 lb — this is a wheeled appliance, not something you carry
- $3,999 puts it against real standby generators
UGREEN's 2kWh option covers full-day home backup at a competitive price, though it isn't expandable like the majors' modular systems.
Best for: Buyers who want a self-contained 2kWh backup without building a modular system.
Where it falls short:
- 55 lb
- Not expandable
