Allpowers R4000 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 $1000 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 69% more energy (3456Wh vs 2048Wh), so it runs the same load proportionally longer.
- Allpowers R4000 has 2400W more surge headroom (6000W vs 3600W) — that decides whether a fridge, pump or AC compressor will actually start.
- UGREEN PowerRoam 2000 is 51.0 lb lighter (55 lb vs 106 lb).
- Allpowers R4000 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
A large expandable unit that undercuts the EcoFlow Delta Pro 3 on price while matching its 4,000W output — the trade is a less established support network.
Best for: Whole-home backup buyers prioritising price per watt over brand.
Where it falls short:
- 106 lb
- Brand support and resale trail the big names
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
