Can the EcoFlow RIVER 2 Pro Run a Full-Size Fridge?
Yes. With 768Wh of LiFePO4 battery capacity (653Wh usable after 85% AC inverter conversion) and a 800W continuous / 1600W surge pure sine wave inverter, the EcoFlow RIVER 2 Pro should run a Full-Size Kitchen Refrigerator (Energy Star) for approximately 9.5 hrs on a single charge.
- Usable Watt-Hours: The EcoFlow RIVER 2 Pro holds 768Wh, which yields about 653Wh of 120V AC power, assuming ~15% DC-to-AC inverter loss.
- Full-Size Fridge Duty Cycle: While active, a Full-Size Fridge pulls 160W (with a 650W startup spike). Over a multi-hour period, its 38% duty cycle averages ~61W per hour (plus ~8W inverter standby overhead).
- Tip: Never multiply a refrigerator's 160W sticker rating by 24 hours straight! Because the insulated cabinet holds cold air, the compressor only cycles on about 35%–40% of the time (~1,450Wh per 24 hours). However, your power station MUST handle the 600W–800W startup compressor surge.
