How Long Will the EcoFlow River 2 Pro Run a Projector?
Updated 2026-10-17 · Yes
About 2.6 hours. The EcoFlow River 2 Pro stores 768Wh, and a projector averages about 250W. That covers about 87% of a typical 3-hour day.
The numbers
| Battery capacity | 768Wh (LFP) |
|---|---|
| Usable energy | 653Wh (85% via AC outlets) |
| Continuous AC output | 800W |
| Surge rating | 1600W |
| Projector running watts | 250W |
| Startup watts | 250W |
| Average draw | 250W |
| Estimated runtime | 2.6 hours |
| Energy per day of typical use | 750Wh |
768Wh × 0.85 = 653Wh usable ÷ 250W average = 2.6 hours

Recharging with solar
The EcoFlow River 2 Pro accepts up to 220W of solar input. In real conditions that harvests about 825Wh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can keep up. A projector uses about 750Wh a day at 3 hours of use, so with enough panels and good sun the EcoFlow River 2 Pro can run it indefinitely.
Tips
- Lamp projectors draw 200–300W; LED and laser models are often under 150W.
- You’ll still have about 550W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The EcoFlow River 2 Pro uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
