How long will the Bluetti Apex 300 run a phone charge?

Will the Bluetti Apex 300 run a phone charge?

Yes — the Apex 300 runs a phone charge comfortably

Its 3840W continuous output easily covers the 10W draw.

Estimated runtime
about 8.3 days (~200 hours)
on a single full charge
Est. usable (AC): 1,997 Wh
Appliance draw: 10 W
Continuous output: 3840 W

How we calculated this

We start from the Bluetti Apex 300's 1,997 Wh of estimated usable energy at the outlet — its 2,764 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the phone charge's 10W draw:

1,997 Wh ÷ 10 W ≈ 199.7 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.
