EcoFlow RIVER 2 Max vs Oukitel P2001
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
EcoFlow RIVER 2 Max costs $600 less. Whether that gap is worth closing depends on what you need to run.
- Oukitel P2001 holds 291% more energy (2000Wh vs 512Wh), so it runs the same load proportionally longer.
- Oukitel P2001 has 3000W more surge headroom (4000W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 Max is 35.8 lb lighter (13.2 lb vs 49 lb).
- Oukitel P2001 is rated for 3,500 cycles vs 3,000 — meaningful if you cycle it daily.
EcoFlow RIVER 2 Max
Double the River 2's capacity and output for $100 more. The sweet spot of EcoFlow's small line for anyone eyeing the occasional small appliance.
Best for: Campers who want headroom over a pure device charger without the size of a 1kWh unit.
Where it falls short:
- Still not enough output for heaters or compressors
- 220W solar input is modest
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
