How Long Will the EcoFlow River 2 Run a Projector?
Updated 2026-10-17 · Briefly
Only briefly: about 52 minutes. The EcoFlow River 2 stores 256Wh, and a projector averages about 250W. That covers about 29% of a typical 3-hour day.
The numbers
| Battery capacity | 256Wh (LFP) |
|---|---|
| Usable energy | 218Wh (85% via AC outlets) |
| Continuous AC output | 300W |
| Surge rating | 600W |
| Projector running watts | 250W |
| Startup watts | 250W |
| Average draw | 250W |
| Estimated runtime | 52 minutes |
| Energy per day of typical use | 750Wh |
256Wh × 0.85 = 218Wh usable ÷ 250W average = 0.9 hours

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 projector uses about 750Wh a day at 3 hours of use, more than the EcoFlow River 2’s best-case solar harvest. Solar will stretch the runtime but not sustain it.
Tips
- Lamp projectors draw 200–300W; LED and laser models are often under 150W.
- The EcoFlow River 2 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
