Learn About Inverters & Converters

Power converters give you the freedom to use your machine anywhere. Inverters convert battery power into alternating current, just as the wall outlets in your home provide. We have a wide selection to accommodate every machine.

  • Inverters convert DC power to AC power

  • Certain CPAP batteries may need a special converter/inverter to be compatible with your machine

Battery Backup

The Freedom battery works as expected. No problems with powering my AirSense CPAP. Recharging is easy. The battery comes with a wall charger. Just note if your run the humidifier a single battery will last approximately 4 hours without running the humidifier 6-8 hrs. You can daisy chain two batteries to extend the run time. Having a battery option is cheaper than having to purchase a portable CPAP machine.

ResMed S9 DC Converter
ResMed S9 DC Converter

Breathing Good Again!

I ordered the 12 volt to 24 volt DC converter cable. My trailer had the 12 volt cigarette socket already installed. The ResMed cable plugged right in and worked flawlessly. The first night I hooked the converter cable up to a 12 volt, 220 CCA utility battery. That was enough power to run through the night. The ResMed S9 unit only pulls 3 amps at 90 watts with the heater on so power consumption is not a problem. Great solution for on the road travel. Also I asked for expedited shipping and it came right on time. Twelve dollar charge to guarantee 2-3 days shipping was not a problem for me.
