BLUETTI AC50B vs EcoFlow RIVER 3 Plus
A starter comparison that keeps unknown fields visible and uses the same runtime assumptions for both stations.
EcoFlow RIVER 3 Plus
286 Wh, 600 W AC output.
Confidence: verified. Last verified: 2026-06-24.
Capacity
Capacity: AC50B is higher by 162 Wh.
AC Output
AC output: AC50B is higher by 100 W.
Solar Input
Solar input: RIVER 3 Plus is higher by 20 W.
The 60 W runtime estimate assumes AC output, 85% conversion efficiency, and 10% battery reserve. It is a sanity check, not a lab-tested result.
Runtime Examples
Same assumptions on both sides: AC output, 85% efficiency, 10% reserve, healthy battery, and steady load.

Planning Watch-Outs
These checks explain where the comparison is strong and where it still needs better source coverage.
- 5 of 5 high-impact comparison fields are filled on both sides.
- AC50B has the larger nominal battery capacity, but usable Wh still depends on reserve, efficiency, temperature, and battery age.
- RIVER 3 Plus is lighter in the tracked weight data, which matters if the station is moved often.
- RIVER 3 Plus has the higher tracked solar input, assuming compatible panels and charge-voltage limits.
