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. String lights use about 100Wh a day at 5 hours of use, so with enough panels and good sun the EcoFlow River 2 Pro can run it indefinitely.

Tips

  • LED string lights for a campsite or patio use 5–25W per strand.
  • You’ll still have about 780W of AC capacity left for other devices at the same time, though they’ll share the same battery.
  • 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.
