How can Transcend get by using such small, compact, lightweight batteries? The answer is simple: Innovative electronics that don't need much power, FAA approved lithium ion batteries like those used in laptop computers, and no juice-guzzling humidifier heating element. With Transcend Batteries you get a full or multipl nights sleep anywhere you choose. It's the world’s smallest, lightest, and most portable CPAP battery connected to the world’s smallest, lightest, and most portable CPAP.

The Transcend Battery Pack plugs directly into the Transcend II CPAP for instant power whenever you need it when you're camping, flying, or sleeping anywhere away from home. But it's great for power outages too! If you experience power fluctuations or outages at home simply plug the Transcend Battery Pack in to the CPAP along with your usual AC (wall) power cord. If the Transcend machine detects a loss of external power, and the battery is attached, the battery pack will take over automatically so you won't miss a moment's sleep.

Each Transcend Battery Pack comes with an integrated charger that operates by connecting to the Transcend Universal AC Power Supply, the Transcend DC Mobile Power Adapter, or the Transcend Solar Charger. Whenever the battery is attached to an external power source, even if the CPAP is in use at the same time, the battery will recharge!

Two versions of the Transcend Battery Pack are available. The P4 Overnight battery is recommended for pressures up to 15CM and will last on average 7-9 hours between charges. The P8 Multi-Night Battery is recommended for pressures up to 19CM and will last on average 14-16 hours between charges.

The battery will recharge whenever attached to AC / DC power, regardless of whether the CPAP is operating or not. The length of run time of the Transcend Battery is dependent on environmental factors such as temperature, altitude, and pressure settings. The Transcend Battery is designed for use in temperatures of 32 to 113°F (0° to 45°C). High pressure settings will decrease run times. High leak rates will adversely effect performance. A very high leak rate may cause the machine to shut down and a moderate leak rate may cause the machine to work harder to compensate for the leak thereby reducing the run time. The Transcend Battery is not waterproof and caution should be taken to keep it dry.

  • Light and long lasting cpap battery

    The cpap extended battery for the Transcend Travel CPAP worked great. Lasted more than 3 nights of a 6 night sleep, and more than 2 nights when slept longer.

  • Ready, set, travel, and sleep

    Battery works like a charm. Not too heavy or bulky. Perfect to store guaranteed power for those nights when you find your next quarters without "juice"! Have used it in remote locations. Pricey, but if you like a good night's sleep... you'll think... amortize it!
