Choosing a CPAP battery or power supply

Zopec Explore 4000 portable CPAP battery

A portable battery covers travel, camping and power cuts. A replacement power supply is the brick and cord that came with your machine. Make sure either one matches your machine before you order.

Getting more nights from a battery

Run time depends on your pressure and on how much heat the machine makes. Turning off the humidifier and heated tubing while you run on battery gives the longest run time. Check the battery listing for the cable your machine needs.

Oxygen concentrator batteries

The Inogen One G5 batteries listed here are for oxygen concentrators, not CPAP machines. See oxygen concentrator batteries.

Questions & answers

How long will a CPAP battery run my machine?

It depends on the battery capacity, your pressure and whether the humidifier is on. A machine uses far less power with the humidifier and heated tubing switched off, so most people turn them off on battery.

Which power supply fits my ResMed machine?

The AirSense 11 uses the 65W power supply. The AirSense 10 and AirCurve 10 use the 90W power supply. They are not interchangeable.

Can I take a CPAP battery on a plane?

Lithium batteries travel in carry-on bags, and airlines set their own limits on battery size. Confirm with your airline before you fly.

Will a Zopec battery work with my CPAP machine?

Zopec batteries work with most CPAP machines, but each machine needs the right output cable. Check the listing for your model before you order.

Do I need a prescription for these?

No. Replacement parts and supplies ship without a prescription. Only complete masks, CPAP and BiPAP machines and oxygen concentrators need one.

Can I return a part if it is the wrong one?

Yes, within 30 days of delivery if it is unused and still in its sealed original packaging. Approved returns are refunded minus a 20% restocking fee, or you can take store credit. Email returns@orderyoursupplies.com to start a return.
