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 desktop computer with monitor uses about 1.2 kWh 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

  • An office desktop plus a 27-inch monitor averages about 150W during normal work.
  • You’ll still have about 350W 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.
