How Long Will the EcoFlow Delta 3 Max Run a Projector?
Updated 2026-10-17 · Yes
About 7 hours. The EcoFlow Delta 3 Max stores 2048Wh, and a projector averages about 250W. At 3 hours of use a day, one charge lasts about 2.3 days.
The numbers
| Battery capacity | 2048Wh (LFP) |
|---|---|
| Usable energy | 1741Wh (85% via AC outlets) |
| Continuous AC output | 2400W |
| Surge rating | 3600W |
| Projector running watts | 250W |
| Startup watts | 250W |
| Average draw | 250W |
| Estimated runtime | 7 hours |
| Energy per day of typical use | 750Wh |
2048Wh × 0.85 = 1741Wh usable ÷ 250W average = 7 hours

Recharging with solar
The EcoFlow Delta 3 Max accepts up to 500W of solar input. In real conditions that harvests about 1.9 kWh 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 Delta 3 Max can run it indefinitely.
Tips
- Lamp projectors draw 200–300W; LED and laser models are often under 150W.
- You’ll still have about 2150W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The EcoFlow Delta 3 Max uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
