Frequently Asked Questions

How long will the EcoFlow Delta Pro run a Space Heater 1500W?

At 1500W, the EcoFlow Delta Pro runs a Space Heater 1500W for approximately 2.04 hours. This uses 3060Wh effective capacity.

Why is actual runtime sometimes shorter?

Cold temperatures, battery age, variable load, and inverter efficiency all reduce real-world runtime below the estimate.

Can I run a Space Heater 1500W overnight on the EcoFlow Delta Pro?

Unlikely at continuous load. The estimated 2.04h runtime at 1500W would not cover a full 8-hour night.
