How Long Will the EcoFlow Delta 3 Power Your Devices?
With a 1024Wh battery and 1800W output (2400W X-Boost, 3600W surge), the Delta 3 can run real household appliances — not just gadgets — through an extended power cut. Typical runtimes below are based on usable capacity after inverter losses:
| Device |
Typical Power Draw |
Estimated Runtime |
| Wi-Fi router / broadband modem |
10W |
Up to 3 days |
| Laptop + router (working from home) |
40–60W |
14–20 hours |
| Full-size fridge (cycling) |
80W average |
10–11 hours |
| 43" TV |
70W |
~12 hours |
| Pedestal fan |
30–40W |
22–28 hours |
| Smartphone recharges |
~15Wh per charge |
~50 full charges |
| Microwave (800W) |
800W while running |
~1 hour of cooking |
| Kettle boils (via X-Boost) |
~110Wh per boil |
~8 boils |
Runtimes are estimates based on approximately 870Wh usable capacity through the AC inverter. Actual results vary with device wattage, temperature and usage. Tip: charge laptops via the 100W USB-C ports for the longest runtime, as it avoids inverter losses. The <10ms UPS switchover keeps essentials running without interruption when the power goes out, and capacity is expandable to 5kWh with extra batteries.
