Everything you need to know about CPAP Batteries

Last updated on November 6th, 2024 at 08:34 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!

Summary:

Please note that this battery is only designed to work with the Transcend CPAP machines, meaning that they will not work with any other CPAP machine.

If you want to use your Transcend CPAP machine or Transcend Auto CPAP machine on the move, then you will need to purchase a Transcend CPAP Battery Pack. Also if you are going camping, on a long-haul flight, or simply away from the mains power, then the Transcend CPAP Battery is perfect for you.

There are two batteries to choose from.

Transcend P4 Overnight Battery for £199. This should power your machine for up to 8 hours.

Alternatively, if you want a longer-lasting battery, you should choose the Transcend P8 Multi-Night Battery for £269. This should power your machine for up to 16 hours.

Can you charge the Transcend Battery from a Mains Source?

Both batteries are chargeable from a mains source or alternatively through DC power using the Transcend DC Mobile Power Adapter. This can be purchased separately for £89.

Do they have a warranty?
