Questions
How long will the EcoFlow RIVER 3 Plus run a refrigerator?
Possibly, but it’s borderline. A typical fridge compressor needs about 1,200 W for a moment to start, right at its 1,200 W peak rating, so it depends on your fridge.
Can the EcoFlow RIVER 3 Plus run a microwave?
No. A 1,000 W microwave draws around 1,500 W from the outlet, more than its 600 W continuous output.
How long does the EcoFlow RIVER 3 Plus take to charge?
With solar at its 220 W maximum input, a full charge takes about 1.3 hours of full sun, or about 1.9 hours at typical real-world panel output.
What battery does the EcoFlow RIVER 3 Plus use and how long will it last?
It uses LiFePO4 cells rated for 3,000 charge cycles, about 858 kWh of total delivered energy. LiFePO4 is the most durable common chemistry for power stations.
