EcoFlow RIVER 3 Plus 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
Bluetti EB3A costs $90 less. Whether that gap is worth closing depends on what you need to run.
- EcoFlow RIVER 3 Plus holds 7% more energy (286Wh vs 268Wh), so it runs the same load proportionally longer.
- EcoFlow RIVER 3 Plus is 0.2 lb lighter (9.9 lb vs 10.1 lb).
- EcoFlow RIVER 3 Plus 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.
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 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
