How Long Will the EcoFlow Delta Pro 3 Run a Washing Machine?
Updated 2026-10-17 · Yes
About 9.9 hours. The EcoFlow Delta Pro 3 stores 4096Wh, and a washing machine averages about 350W because it cycles on roughly 70% of the time. At 1 hours of use a day, one charge lasts about 9.9 days.
The numbers
| Battery capacity | 4096Wh (LFP) |
|---|---|
| Usable energy | 3482Wh (85% via AC outlets) |
| Continuous AC output | 4000W |
| Surge rating | 8000W |
| Washing machine running watts | 500W |
| Startup watts | 1500W |
| Average draw | 350W |
| Estimated runtime | 9.9 hours |
| Energy per day of typical use | 350Wh |
4096Wh × 0.85 = 3482Wh usable ÷ 350W average = 9.9 hours

Recharging with solar
The EcoFlow Delta Pro 3 accepts up to 2600W of solar input. In real conditions that harvests about 9.8 kWh on a sunny day (5 peak-sun hours), or about 750Wh with one 200W panel.
Solar can keep up. A washing machine uses about 350Wh a day at 1 hours of use, so with enough panels and good sun the EcoFlow Delta Pro 3 can run it indefinitely.
Tips
- A cold-water wash uses about 0.3–0.5 kWh per load. Hot-water washes draw on your water heater, not the washer.
- You’ll still have about 3500W of AC capacity left for other devices at the same time, though they’ll share the same battery.
- The EcoFlow Delta Pro 3 uses LiFePO4 (LFP) cells, rated for thousands of cycles, so running it down daily won’t wear it out quickly.
