How Long Will the EcoFlow Delta 3 Max Run a Circular Saw?
Updated 2026-10-17 · Yes
About 1.2 hours. The EcoFlow Delta 3 Max stores 2048Wh, and a circular saw averages about 1400W. That’s enough for about 4 typical 15-minute uses.
The numbers
| Battery capacity | 2048Wh (LFP) |
|---|---|
| Usable energy | 1741Wh (85% via AC outlets) |
| Continuous AC output | 2400W |
| Surge rating | 3600W |
| Circular saw running watts | 1400W |
| Startup watts | 2600W |
| Average draw | 1400W |
| Estimated runtime | 1.2 hours |
| Energy per day of typical use | 350Wh |
2048Wh × 0.85 = 1741Wh usable ÷ 1400W average = 1.2 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 circular saw uses about 350Wh a day at 0.25 hours of use, so with enough panels and good sun the EcoFlow Delta 3 Max can run it indefinitely.
Tips
- Corded 7¼-inch saws pull a big inrush when the blade spins up. That surge, not total energy, decides whether it works.
- You’ll still have about 1000W 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.
