Recharging with solar
The EcoFlow River 3 accepts up to 110W of solar input. In real conditions that harvests about 413Wh on a sunny day (5 peak-sun hours).
Tips
- Portable ACs (10,000 BTU class) are less efficient than window units because they vent hot air through a hose.
- The EcoFlow River 3 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
