How long will the EcoFlow Delta Pro 3 run a e-bike battery charge?

Will the EcoFlow Delta Pro 3 run a e-bike battery charge?

Yes — the Delta Pro 3 runs a e-bike battery charge comfortably

Its 4000W continuous output easily covers the 150W draw.

Estimated runtime
about 21 hours
on a single full charge
Est. usable (AC): 3,133 Wh
Appliance draw: 150 W
Continuous output: 4000 W

How we calculated this

We start from the EcoFlow Delta Pro 3's 3,133 Wh of estimated usable energy at the outlet — its 4,096 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the e-bike battery charge's 150W draw:

3,133 Wh ÷ 150 W ≈ 20.9 hours

Real-world runtime varies with temperature, cable losses, and how hard the appliance actually cycles. Treat this as a solid estimate, not a guarantee.
