Recharging with solar
The EcoFlow River 2 accepts up to 110W of solar input. In real conditions that harvests about 413Wh on a sunny day (5 peak-sun hours).
Solar can’t fully keep up. A slow cooker uses about 960Wh a day at 8 hours of use, more than the EcoFlow River 2’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- On low, a slow cooker cycles to hold temperature, averaging around 120W.
- You’ll still have about 100W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The EcoFlow River 2 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
