Transcend comes with a standard AC power connector and offers a battery and mobile power adaptor as options that are sold separately.

Yes! Transcend has a mobile power adaptor available that allows it to plug into the DC power outlet in your car, truck, RV, boat, camper, or wherever you choose to sleep. You can also use the mobile power adaptor to recharge the Transcend battery pack.

Yes, make sure the battery is fully charged before using it with Transcend for the first time.

Yes, the Transcend battery can be recharged with the AC power supply or mobile power adaptor while delivering therapy.

The Transcend P4 battery system provides sufficient power to operate the device for 7-9 hours at a pressure setting of 14 cmH2O. The Transcend P8 battery system provides power for 14-16 hours of use at the same setting. Both the P4 and P8 batteries are designed to accommodate at least 300 discharge/recharge cycles with standard use.

Yes. There are two battery options available. The P4 Overnight™ Battery System is about the size of a deck of cards and weighs about half a pound. The P4 battery is designed to provide one night’s CPAP operation (7-9 hours operation at 14 cmH2O).
The P8 Multi-Night™ Battery System covers the same footprint as the P4 battery, but is approximately twice the thickness. The P8 battery weighs just over one pound and is designed to provide two night’s CPAP operation (14-16 hours operation at 14 cmH2O).
Both the P4 and P8 batteries are lithium ion. From a dead charge, it takes approximately 5 hours to fully charge the P4 battery and 8 hours to charge the P8 battery using AC line power or DC power (using an optional Transcend Mobile Power Adaptor). Either battery should last a minimum of 300 charging cycles.
P4 and P8 batteries can also be charged using the Transcend Solar Battery Charger. Note, however, the charge time using the Transcend Solar Battery Charger will be longer and will depend on the availability of sunlight. From a dead charge, the Transcend Solar Battery Charger will charge the P4 battery in approximately 6 hours if the Charger is placed in direct sunlight, while 12 hours will be needed to charge the P8 battery.

Yes. The P4 and P8 batteries can be used in line with AC power (home wall power) or DC power (such as in a car, boat or RV). By doing so, the P4 or P8 battery will provide an uninterrupted power supply, just like a laptop computer battery. In the event of a storm or power outage, using the Transcend battery in line will guarantee power for the therapy you need for a good night’s sleep.
