Bluetti EB3A vs EcoFlow RIVER 2 Max
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
Bluetti EB3A costs $60 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow RIVER 2 Max holds 91% more energy (512Wh vs 268Wh), so it runs the same load proportionally longer.
- Bluetti EB3A has 200W more surge headroom (1200W vs 1000W) — that decides whether a fridge, pump or AC compressor will actually start.
- Bluetti EB3A is 3.1 lb lighter (10.1 lb vs 13.2 lb).
- EcoFlow RIVER 2 Max is rated for 3,000 cycles vs 2,500 — meaningful if you cycle it daily.
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.
The budget veteran. 268Wh at $239 with a 30-minute recharge — still one of the fastest-charging small units you can buy.
Best for: Budget campers who value fast top-ups between trips.
Where it falls short:
- 2500 cycles is the lowest here
- 268Wh empties fast under real load
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
