How Long Will the EcoFlow River 2 Max Run an LED Light Bulb?

Updated 2026-10-17 · Yes

About 44 hours. The EcoFlow River 2 Max stores 512Wh, and an LED light bulb averages about 10W. At 6 hours of use a day, one charge lasts about 7.3 days.

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 keep up. An LED light bulb uses about 60Wh a day at 6 hours of use, so with enough panels and good sun the EcoFlow River 2 Max can run it indefinitely.

Tips

  • A 60W-equivalent LED bulb uses about 9–10W. Runtimes get very long, so battery self-discharge eventually becomes the limit.
  • You’ll still have about 490W 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.
