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. A nebulizer uses about 80Wh a day at 1 hours of use, so with enough panels and good sun the EcoFlow River 2 Max can run it indefinitely.

Tips

  • Compressor nebulizers use little energy because treatments last 10–15 minutes.
  • You’ll still have about 420W 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.
