Common questions
How long will the EcoFlow River 2 Pro run a full-size fridge?
About 0.4 days on a full charge, using our planning figures (85% of rated capacity usable, fridge at 1,500Wh per day). Real runtime depends on the fridge’s duty cycle and ambient temperature.
How many nights will it run a CPAP?
About 1.4 nights at 480Wh per night (60W for 8 hours, humidifier on). Turning the humidifier and heated tube off stretches that considerably.
Can its capacity be expanded?
No — the EcoFlow River 2 Pro is a fixed-capacity design at 768Wh. If you expect to outgrow it, look at the expandable models in the comparison chart.
Does it work as a UPS?
Its published switchover is ≤ 30 ms, fast enough for most electronics to ride through an outage without rebooting.
