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 mini fridge uses about 816Wh a day at 24 hours of use, so with enough panels and good sun the EcoFlow River 2 Max can run it indefinitely.
Tips
- Compact dorm-style fridges run small compressors that cycle about 40% of the time.
- You’ll still have about 415W 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.
