The numbers
| Battery capacity | 245Wh (LFP) |
|---|---|
| Usable energy | 208Wh (85% via AC outlets) |
| Continuous AC output | 300W |
| Surge rating | 600W |
| Ceiling fan running watts | 60W |
| Startup watts | 80W |
| Average draw | 60W |
| Estimated runtime | 3.5 hours |
| Energy per day of typical use | 480Wh |
245Wh × 0.85 = 208Wh usable ÷ 60W average = 3.5 hours

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’t fully keep up. A ceiling fan uses about 480Wh a day at 8 hours of use, more than the EcoFlow River 3’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- Ceiling fans are wired into the house, so you'd only run one from a station with a transfer switch or home backup kit.
- You’ll still have about 240W 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.
