The differences that matter
- Continuous output: 300 W vs 600 W → the RIVER 3 Plus runs several appliances together, the AC2A only a light load.
- Noise level: 45 dB vs 30 dB (manufacturer-rated) → the AC2A is more audible when its fan kicks in.
- Switchover time: 20 ms vs 10 ms → the RIVER 3 Plus covers a blackout with a shorter interruption.
- Maximum charge power: 0.27 kW vs 0.38 kW → the RIVER 3 Plus recharges faster from mains.
Which one to choose
Choose BLUETTI AC2A if…
The AC2A holds a continuous load up to 300 W, enough for light use, and needs no app for first power-on. The trade-off is a more noticeable fan, manufacturer-rated at 45 dB against the RIVER 3 Plus's 30 dB.
Choose EcoFlow RIVER 3 Plus if…
The RIVER 3 Plus holds a continuous load up to 600 W, double the AC2A, with a faster switchover time during a blackout, 10 ms against 20 ms. In exchange it's a quieter unit built for more demanding use.
