EcoFlow RIVER 3 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 $40 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow RIVER 2 holds 4% more energy (256Wh vs 245Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 2 is 0.1 lb lighter (7.7 lb vs 7.8 lb).
We'd skip the EcoFlow RIVER 3 in this matchup. It costs $40 more than the EcoFlow RIVER 2 while matching or trailing it on capacity, surge and cycle life — there's no spec here that justifies the premium.
A glorified power bank with AC outlets — and that's fine if that's what you need. 245Wh runs devices, not appliances.
Best for: Weekend campers charging phones, cameras and a laptop.
Where it falls short:
- 300W output rules out anything with a heating element
- No expansion path
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
