For longer battery use, we suggest using a deep-cycle marine battery to power the machine. A deep-cycle marine battery is heavier than the ordinary battery, but it has many advantages. The battery is easily found at auto shops and it provides power to the machine for an extended period of time. For example, a CPAP machine set at 10 cm H20 and charged on a deep-cycle marine battery will usually last three nights before it needs to be recharged.
There are small, portable battery packs that will operate a CPAP set at 10cm for at least one night, or about eight hours. CPAP.com sells full Battery Kits
that come with everything needed to run your machine off battery power including the correct cables needed for your machine and a battery. You can find the battery kit for your machine Here
. On each battery kit page, you can input your machine and pressure setting to see an estimate battery life for your machine.
Some machines have batteries created to be used specifically with them only. Here are some of the machines we carry with integrated or specialized battery options: Transcend EZEX miniCPAP™ Machine Z1 Travel CPAP Machine Transcend Auto miniCPAP™ Machine with EZEX Z1 Auto Travel CPAP Machine
