How Long Will the EcoFlow River 2 Pro Run a 12V Car Fridge?

Updated 2026-10-17 · Yes

About 39 hours. The EcoFlow River 2 Pro stores 768Wh, and a 12V car fridge averages about 18W because it cycles on roughly 40% of the time. That’s about 1.6 days of round-the-clock use.

Recharging with solar

The EcoFlow River 2 Pro accepts up to 220W of solar input. In real conditions that harvests about 825Wh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.

Solar can keep up. A 12V car fridge uses about 432Wh a day at 24 hours of use, so with enough panels and good sun the EcoFlow River 2 Pro can run it indefinitely.

Tips

  • Compressor coolers like Dometic, ICECO and BougeRV plug into the 12V car port, which skips inverter losses entirely.
  • Running it from the EcoFlow River 2 Pro’s DC port instead of the AC outlet avoids inverter losses: about 54Wh more usable energy.
  • The EcoFlow River 2 Pro uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
