BLUETTI AC2A vs EcoFlow RIVER 3 Plus Wireless
Technical comparison · Ultraportable
Two ultraportables of different output: the BLUETTI AC2A at 300 W and 3.6 kg, the EcoFlow RIVER 3 Plus Wireless at 600 W and 5.2 kg, going by manufacturer-declared figures. The question is whether 300 W is enough for the devices you want to power.

The differences that matter
- Continuous output, 300 W vs 600 W → a resistive appliance above 300 W trips the first and runs on the second.
- Capacity, 205 Wh vs 286 Wh → at a 100 W load, about 2 hours against nearly 3.
- Weight, 3.6 kg vs 5.2 kg → 1.6 kg more to carry every time you move it.
- Noise, 45 dB vs 30 dB → the first's fan is audible in a quiet room.
Which one to choose
Choose BLUETTI AC2A if…
you power a router, lights, phones and a laptop and want the lowest weight: 3.6 kg and 205 Wh, up to 200 W of solar input and a 5-year warranty. You accept a 300 W continuous limit (600 W peak) and a 45 dB fan.
Choose EcoFlow RIVER 3 Plus Wireless if…
you connect several devices at once: 600 W continuous with a 1200 W peak, three AC outlets, 286 Wh and 30 dB. You accept carrying 1.6 kg more; the warranty is 5 years, same as the other.
