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.
Tips
- iPads and Android tablets hold 25–40Wh.
- Running it from the EcoFlow River 2 Max’s DC port instead of the AC outlet avoids inverter losses: about 36Wh more usable energy.
- 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.
