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. A Wi-Fi router and modem uses about 480Wh a day at 24 hours of use, so with enough panels and good sun the EcoFlow River 2 Pro can run it indefinitely.

Tips

  • Keeping internet up during an outage costs very little power, as long as your ISP's equipment down the street still has power too.
  • Running it from the EcoFlow River 2 Pro’s DC port instead of the AC outlet avoids inverter losses: about 54Wh more usable energy.
  • 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.
