BLUETTI EB3A vs EcoFlow RIVER 3 Plus
BLUETTI EB3A and EcoFlow RIVER 3 Plus hold almost the same battery and sell to the same person, which means the decision comes down to the details around the pack rather than the pack itself.
Two machines aimed at the same buyer
EcoFlow RIVER 3 Plus holds a slim 7% more battery — 286Wh against 268Wh — and that is what decides how long either one lasts on the same load.
Both invert to 600W, 2 outlets, so the same appliances are on and off the table for either.
EcoFlow RIVER 3 Plus takes 220W of solar against 200W, which only matters if a panel is your way back to full — and matters a great deal if it is.
EcoFlow RIVER 3 Plus refills faster from the wall, accepting 380W against 350W.
Drawn from 7 specifications each maker publishes, of which 7 differ. We have not handled either machine — see our methodology.
Side by side
| Specification | BLUETTI EB3A | EcoFlow RIVER 3 Plus |
|---|---|---|
| Battery capacity | 268Wh | 286Whbetter |
| AC output | 600W, 2 outlets | 600W |
| Max solar input | 200W | 220Wbetter |
| AC input | 350W | 380Wbetter |
| Cell chemistry | LiFePO4 | LiFePO4 |
| Weight | 10.1 lbs | 10.4 lb |
| Dimensions | 10.0x7.1x7.2 in | 9.2×9.1×5.8 in |
What that capacity actually runs
Watt-hours are hard to picture, so here is each pack as runtime on the loads a machine this size is usually bought for. Both columns assume 85% inverter efficiency — the conservative end of what these are rated at — so read every figure as a floor.
| Load | BLUETTI EB3A | EcoFlow RIVER 3 Plus |
|---|---|---|
| Phone (10Wh per charge) | 22 charges | 24 charges |
| Laptop (60W) | 3.8 hours | 4.1 hours |
| CPAP, no humidifier (40W) | 5.7 hours | 6.1 hours |
| Camera batteries (15Wh each) | 15 charges | 16 charges |
| LED camp lights (10W) | 23 hours | 1.0 days |
From solar alone, at 70% of the panel input each maker quotes — a realistic day rather than a lab figure — the BLUETTI EB3A needs about 1.9 hours of good sun to refill , and the EcoFlow RIVER 3 Plus about 1.9 hours.
Published by only one of them
A figure missing from a spec sheet is not a zero — it is a number the maker chose not to state. These appear on one page and not the other, so they cannot be compared, only noted.
- BLUETTI EB3A — Cycle life: 2,500+ cycles to 80%
- BLUETTI EB3A — AC outlets: 2 x 120V/5A Outlets
- BLUETTI EB3A — USB-C output: 1 × 100W max
- BLUETTI EB3A — Warranty: 24 Months
Where this comparison stops
Everything above is what the makers publish, not what either machine did in front of us. We own neither, so there is no noise measurement, no thermal behaviour under sustained load, and no view on how either holds up after two years. Makers also measure differently — cycle life at 80% capacity is not the same test as cycle life at 70% — so figures that look comparable sometimes are not. Treat this as a way to build a shortlist quickly, and read the caveats on our methodology page before you let a number decide.

Neither figure above is a price. These two move independently and often, and whichever is discounted this week is usually the answer when the specifications are as close as they are here.
