How Long Will the EcoFlow River 2 Max Run a Slow Cooker?

Updated 2026-10-17 · Yes

About 3.6 hours. The EcoFlow River 2 Max stores 512Wh, and a slow cooker averages about 120W because it cycles on roughly 60% of the time. That covers about 45% of a typical 8-hour day.

Recharging with solar

The EcoFlow River 2 Max 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’t fully keep up. A slow cooker uses about 960Wh a day at 8 hours of use, more than the EcoFlow River 2 Max’s best-case solar harvest. Solar will stretch the runtime but not sustain it.

Tips

  • On low, a slow cooker cycles to hold temperature, averaging around 120W.
  • You’ll still have about 300W of AC capacity left for other devices at the same time, though they’ll share the same battery.
  • The EcoFlow River 2 Max uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
