Rechargeable Lithium-ion Battery Pack is designed specifically to integrate with our Light bars, Flexible LED Lights, or 24V/12V/5V DC electronic device. The Lithium Ion Battery Pack can be recharged without limitations, as the battery is designed for a slow charge process (5 hours for full charge), which helps the battery pack last longer.

Review: Resmed airsense 10 engineering notes - The rated input voltage for the air 10 CPAP is 24 volts. This battery outputs anywhere between 20 and 29.4 volts. If you are concerned, like I was about the input voltage, there are a few solutions. You can buy two of the 12 volt batteries and hook them in series. This will give you a max voltage of about 25 or 26 volts instead of 29 volts. Another option is to use a DC to DC converter like I am doing. There is a converter made by Bix power specifically for the air sense 10 for about 59 bucks. You will need a few adapters and/or be able to solder to get it all hooked up right but in the end you will have a superior product for about half the price of most others. This will allow this battery to be used as a UPS backup power instead of just for camping etc. It will switch automatically if power is lost in the middle of the night. You will never know that power went out until you get up in the morning! Review: Airline Sized and Durable, Two-nights for Resmed Airsense 10 - Gave me two nights power for a Redmed Airsense 10 with no humidity or heat turned on. Fits in the Resmed case where the power adapter normally goes. I've tried a couple small camping batteries before. I'll use them for other things because this unit is perfect for the CPAP. I hadn't gotten the Resmed adapter yet so I used a 24v to car female then a car to Resmed 12-24v adapter.
