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).
Solar can keep up. A 55-inch TV uses about 400Wh a day at 4 hours of use, so with enough panels and good sun the EcoFlow River 3 can run it indefinitely.
Tips
- A modern 55-inch LED TV draws 60–120W depending on brightness. OLED and large TVs can draw more.
- You’ll still have about 200W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The EcoFlow River 3 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
