Can the EcoFlow RIVER 2 Pro Run a 12V Camping 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 12V Portable Camping Fridge / Cooler (45L) for approximately 27.2 hrs (~1.1 days) 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.
- 12V Camping Fridge Duty Cycle: While active, a 12V Camping Fridge pulls 45W (with a 90W startup spike). Over a multi-hour period, its 35% duty cycle averages ~16W per hour (plus ~8W inverter standby overhead).
- Tip: Always plug your portable camping fridge into the **12V regulated DC cigarette lighter port** on your power station, NOT the 120V AC wall outlet! Using 12V DC avoids inverter conversion losses and extends runtime by 25%–30%.
