How Long Will the EcoFlow River 3 Run an LED Light Bulb?
Updated 2026-10-17 · Yes
About 21 hours. The EcoFlow River 3 stores 245Wh, and an LED light bulb averages about 10W. At 6 hours of use a day, one charge lasts about 3.5 days.
The numbers
| Battery capacity | 245Wh (LFP) |
|---|---|
| Usable energy | 208Wh (85% via AC outlets) |
| Continuous AC output | 300W |
| Surge rating | 600W |
| LED light bulb running watts | 10W |
| Startup watts | 10W |
| Average draw | 10W |
| Estimated runtime | 21 hours |
| Energy per day of typical use | 60Wh |
245Wh × 0.85 = 208Wh usable ÷ 10W average = 20.8 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 keep up. An LED light bulb uses about 60Wh a day at 6 hours of use, so with enough panels and good sun the EcoFlow River 3 can run it indefinitely.
Tips
- A 60W-equivalent LED bulb uses about 9–10W. Runtimes get very long, so battery self-discharge eventually becomes the limit.
- You’ll still have about 290W 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.
