Transcend CPAP Batteries from Somnetics

Maximise your Transcend’s portability

To use your Transcend 3 CPAP Machine or Transcend II Series CPAP Machine on the move, combine it with a battery pack. If you are going camping, flying overnight, or simply away from mains power for any reason, then a battery is the essential companion to your Transcend 3 CPAP Machine.

There are two batteries to choose from. The P4 powers your Transcend for up to 8 hours, while the P8 has enough power for up to 16 hours. Figures are based on a pressure of 14cmH2O; higher pressures may not last as long and staying at high altitude may also reduce run time as the machine will need to work harder.

Save £50 when ordering at the same time as your Transcend machine

Purchase either Transcend Battery at the same time as your Transcend 3 CPAP Machine (any model) and you will get an automatic £50 discount at the checkout!

Both batteries are chargeable from a mains source or through DC power using the Transcend DC Mobile Power Adapter (available separately). Mains charging uses your Transcend’s power supply, and both batteries can power your machine at the same time as being charged. This offers the added benefit of a seamless trip-over in case of a power-cut. The machine will keep running off the battery so you can enjoy uninterrupted sleep.

The P4 is comparable in size to a large deck of playing cards. The larger P8 is twice as thick, but still incredibly small.

The dimensions of the Transcend P4 Battery are 104mm x 80mm x 23mm, while it weighs 0.28kg. It takes under five hours to charge when fully depleted, providing 7-9 hours of power at 14cmH2O. It has an output of 14.4V, with a capacity of 2.6Ah or 37Wh.

The dimensions of the Transcend P8 Battery are 110mm x 80mm x 42mm, while it weighs 0.5kg. It takes under eight hours to charge when fully depleted, providing 14-16 hours charge at 14cmH2O. It has an output of 14.4V, with a capacity of 5.2Ah or 75Wh.

Both batteries are only compatible with the Transcend CPAP Machine; they are not designed to work work with any other CPAP machine.

Both batteries have a warranty of 9 months. If storing a battery for longer periods, make sure it is charged up first, and consider topping up every few months.
