EcoFlow RIVER 3 Plus vs EcoFlow RIVER 2
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 costs $130 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow RIVER 3 Plus holds 12% more energy (286Wh vs 256Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 3 Plus has 600W more surge headroom (1200W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 2 is 2.2 lb lighter (7.7 lb vs 9.9 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.
Doubles the River 3's output for $90 more, and adds an expansion battery port. The better buy of the two unless weight is everything.
Best for: Campers who want one unit that covers devices plus the occasional small appliance.
Where it falls short:
- 286Wh alone is a single evening of real use
- 220W solar input is modest
The cheapest way into LiFePO4. 256Wh is a device charger, but at under $200 with a 60-minute recharge it's hard to argue with.
Best for: Budget campers who just need to keep phones, cameras and a laptop alive.
Where it falls short:
- 300W output runs devices only
- 256Wh is a single evening of real use
