EcoFlow RIVER 3 vs Bluetti EB3A
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
These two cost the same, so the decision comes down to what you're powering.
- Bluetti EB3A holds 9% more energy (268Wh vs 245Wh), so it runs the same load proportionally longer.
- Bluetti EB3A has 600W more surge headroom (1200W vs 600W) — that decides whether a fridge, pump or AC compressor will actually start.
- EcoFlow RIVER 3 is 2.3 lb lighter (7.8 lb vs 10.1 lb).
- EcoFlow RIVER 3 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.
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 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
