Everything you need to know about CPAP Batteries

Last updated on August 1st, 2023 at 11:16 am

CPAP batteries are essential for when you go travelling with your CPAP machine. They are a great back up source of power, and ensure that you can continue to use your CPAP therapy wherever you go!

If you own a CPAP machine and are planning on travelling soon, then you might be considering ordering an additional battery pack.

A battery pack is a great solution for those uncertain of being able to access mains power while away. This might be because you are going on a long-haul flight, camping, or visiting a country with unreliable mains power. There a few battery packs available, so you have come to the right place to find out which battery would be most compatible with your CPAP.

You may need to purchase an additional DC cable or adaptor before these batteries can safely power your CPAP or BiPAP machine, if you do not own a DC cable already.

Unless you have a Transcend Machine, the Tracer 12V CPAP battery pack is most likely to be the greatest option for you, in terms of price and the way it works.

Universal batteries such as the Tracer battery, are designed to work with any device that corresponds with the voltage output, of 12V.

The Tracer Battery Pack is most likely to be the best battery option to power your 12V machine. It is one of the most convenient options in terms of cost, usage and performance abilities. It is also worth mentioning that with its lightweight design, weighing just 600g, it is the perfect travel companion.

Once combined with the correct DC cable for your machine, you will be able to get up to two nights sleep!
