About 8 hours from a full charge. A mini fridge averages about 30 W (100 W running, on about 30% of the time), and the 286 Wh battery gives about 243 Wh after inverter losses. That is 12% of the battery an hour.

Will the EcoFlow RIVER 3 Plus start a mini fridge?

Yes. It needs about 500 W for a moment when the compressor starts, and the EcoFlow RIVER 3 Plus is rated for 1,200 W surge, 2.4 times that. Avoid starting other motors at the same moment.

How much of the battery does a mini fridge use in a day?

About 720 Wh a day (30 W × 24 hours), more than the 243 Wh the EcoFlow RIVER 3 Plus can deliver, so plan to recharge every 8 hours.
