How long will the EcoFlow RIVER 3 Plus run a full-size fridge?

About 5.5 hours from a full charge. A full-size fridge averages about 45 W (150 W running, on about 30% of the time), and the 286 Wh battery gives about 243 Wh after inverter losses. That is 19% of the battery an hour.

Will the EcoFlow RIVER 3 Plus start a full-size fridge?

Yes. It needs about 1,000 W for a moment when the compressor starts, and the EcoFlow RIVER 3 Plus is rated for 1,200 W surge, 1.2 times that. Avoid starting other motors at the same moment.

How much of the battery does a full-size fridge use in a day?

About 1,080 Wh a day (45 W × 24 hours), more than the 243 Wh the EcoFlow RIVER 3 Plus can deliver, so plan to recharge every 5.5 hours.
