Estimated runtime

about 6 hours

on a single full charge

Est. usable (AC): 220 Wh

Appliance draw: 40 W

Continuous output: 300 W

How we calculated this

We start from the Jackery Explorer 300 Plus's 220 Wh of estimated usable energy at the outlet — its 288 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the cpap machine's 40W draw:

220 Wh ÷ 40 W ≈ 5.5 hours

Heads up: a cpap machine is a motor/compressor load that spikes 2–3× on startup. The Jackery Explorer 300 Plus's 300W continuous / 600W 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.
