Can the Jackery Explorer 300 Plus Run a CPAP Machine?
Yes. With 288Wh of LiFePO4 battery capacity (245Wh usable after 85% AC inverter conversion) and a 300W continuous / 600W surge pure sine wave inverter, the Jackery Explorer 300 Plus should run a CPAP / BiPAP Machine (Standard Mode) for approximately 4.6 hrs on a single charge.
- Usable Watt-Hours: The Jackery Explorer 300 Plus holds 288Wh, which yields about 245Wh of 120V AC power, assuming ~15% DC-to-AC inverter loss.
- CPAP Machine Duty Cycle: While active, a CPAP Machine pulls 45W (with a 60W startup spike). Over a multi-hour period, its 100% duty cycle averages ~45W per hour (plus ~8W inverter standby overhead).
- Tip: Look for a power station with UPS/EPS (<20ms Auto-Switchover) like the Jackery 1000 v2, Anker SOLIX C1000, or EcoFlow DELTA 2. You plug the power station into the wall and your CPAP into the power station—if the grid goes down at 2:00 AM, your CPAP stays on without skipping a breath.

Inexpensive Add-Ons for Running a CPAP Machine on Battery
Running a CPAP from the 12V/DC port skips inverter losses and can roughly double runtime.
Measures what your appliance actually draws, so you size from real numbers instead of estimates.
Lets the power station sit where it's convenient without voltage drop on motor loads.
