Recharging with solar

The EcoFlow Delta 2 accepts up to 500W of solar input. In real conditions that harvests about 1.9 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.

Tips

  • Most phones hold 12–19Wh. Charge from a USB port rather than the AC outlet to skip inverter losses.
  • Running it from the EcoFlow Delta 2’s DC port instead of the AC outlet avoids inverter losses: about 72Wh more usable energy.
  • The EcoFlow Delta 2 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
