The Transcend II CPAP machine is one of the few that has the best power options available. The P4 has been designed for use by the Transcend II CPAP machine only.
Because it weighs only 450 grams, it is a very light power option for a CPAP machine. Its weight also makes it easy to travel with. Aside from just being light, it is also small and compact. You can easily place it next to your bed, or even carry it around with you by placing it in a pouch around your arm or chest.
When used at a pressure of 14 cm H20, the batteries can last for up to 9 hours. They are easily rechargeable through the mains or through your car’s battery.
In case you live in an area that is prone to constant power outages, then you can choose to connect the batteries to the machine and then to the mains. This means that even if there is an abrupt power cut, you will still be able to power your machine.
