Weaknesses
- 300 W output: not enough for microwaves, kettles or heaters
Strengths and weaknesses are calculated against current stations from half to double its capacity.
What can the RIVER 2 run?
Estimated time running one device on its own, at 85% usable capacity and with 10% power headroom. To combine devices, use the runtime calculator.
“Borderline” means the station’s rating is within 10% of what the device needs, so it depends on your exact appliance.

Questions
How long will the EcoFlow RIVER 2 run a refrigerator?
It can’t reliably start a typical full-size refrigerator. The compressor’s start-up surge (about 1,200 W) exceeds its 600 W peak output.
Can the EcoFlow RIVER 2 run a microwave?
No. A 1,000 W microwave draws around 1,500 W from the outlet, more than its 300 W continuous output.
How long does the EcoFlow RIVER 2 take to charge?
About 60 minutes from a wall outlet (manufacturer figure). With solar at its 110 W maximum input, a full charge takes about 2.3 hours of full sun, or about 3.3 hours at typical real-world panel output.
What battery does the EcoFlow RIVER 2 use and how long will it last?
It uses LiFePO4 cells rated for 3,000 charge cycles, about 768 kWh of total delivered energy. LiFePO4 is the most durable common chemistry for power stations.
