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
Oukitel P2001 costs $1400 less. Whether that gap is worth closing depends on what you need to run.
- Allpowers R4000 holds 73% more energy (3456Wh vs 2000Wh), so it runs the same load proportionally longer.
- Allpowers R4000 has 2000W more surge headroom (6000W vs 4000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Oukitel P2001 is 57.0 lb lighter (49 lb vs 106 lb).
Allpowers R4000
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
Oukitel P2001
An older Oukitel 2kWh, still sold cheap. Solid on paper with 2,000W and expandability, but the 500W solar input is a real limit off-grid.
Best for: Budget buyers who recharge mainly from the wall, not panels.
Where it falls short:
- 500W solar input is low for 2kWh
- Smaller support network
