Estimated runtime

about 2.3 days (~55 hours)

on a single full charge

Est. usable (AC): 2,178 Wh

Appliance draw: 40 W

Continuous output: 2400 W

How we calculated this

We start from the Bluetti Elite 300's 2,178 Wh of estimated usable energy at the outlet — its 3,014 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the cpap machine's 40W draw:

2,178 Wh ÷ 40 W ≈ 54.5 hours

Heads up: a cpap machine is a motor/compressor load that spikes 2–3× on startup. The Bluetti Elite 300's 2400W continuous / 4800W surge output has plenty of headroom for that spike.

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