How long does the EcoFlow RIVER 3 run common devices?
Runtimes are calculated from the rated 245 Wh, not tested. Each row is one device, mode and power path. A row reads "Won't run" when the device needs more than the EcoFlow RIVER 3 can supply, with the reason.
12V fridges and coolers

What about electric blankets?
We show no runtimes for heated blankets. The Berkshire Blanket & Home Co. manual says not to use its blankets with generators, power converters or inverters, and a power station's AC outlet is an inverter. Read why.
