Battery Charger:


The Lightweight Battery Pack is compatible with machines from all major manufacturers including ResMed, DeVilbiss, Respironics, Fisher & Paykel, and more. And it really works providing average run times of 1-2 nights with most machines so you can take your CPAP on vacation, camping, on the road, or in the air!

At the heart of the Lightweight Battery Pack is an ultra-small, ultra-light (less than 1.5 pounds), ultra-powerful Lithium Ion battery like those found in many laptop computers. Lithium Ion batteries are small and powerful so you can expect to get hundreds of uses out of your battery pack if it is maintained properly. In addition each pack comes with a convenient Travel Bag and a Battery Recharger.

The Lightweight Battery Pack's specially designed AC Charger with Universal Power Supply effectively recharges the battery without overcharging it. To make things even easier a green light on the charger will let you know when the battery is fully recharged. Because the charger has a Universal Power Supply it can be used in most locations worldwide (a plug adapter may be needed for charging outside of North America).

Current FAA regulations allow CPAP Machines and Lithium Ion Batteries (like the one in this battery pack) to be carried onboard commercial flights; however it is always important to check with your airline prior to travel to determine exactly what requirements they have for carrying medical equipment on board.

The Lightweight Battery Pack is equipped with a DC Power Socket like the cigarette style power outlet found in most vehicles. To power your CPAP with the battery simply connect your machine to the pack using a manufacturer approved DC cord. We offer packages with DC Cords for Philips Respironics, ResMed, Fisher & Paykel, and DeVilbiss machines; but if you already own a DC cord for your machine there is no need to purchase another! The battery pack will work fine with any manufacturer approved DC Power Cord. Review your CPAP manual if you are unsure about whether your system has DC power capabilities.

The Lightweight Travel Battery Pack is designed to help you get a good night's sleep. The amount of time the pack will power your system between recharges will vary depending on your specific machine, pressure and setup. Follow these usage tips to get the most out of your battery pack:

  • For best results batteries should be fully depleted and recharged on a regular basis (every 4-6 weeks).
  • Using a heated humidifier and/or heated tubing with the battery pack will significantly reduce run times and may effect overall CPAP functionality. To help extend run times turn the heated humidifiers and heated tubing off when using a CPAP battery pack. Heated humidifiers can be used in passover -- non heated -- mode when using a battery pack.
  • If your CPAP machine is equipped with ECO, Power Saver, or Airplane Mode activate it to extend battery life between recharges.
  • Comfort features -- like C-Flex, A-Flex and EPR -- and leaks can increase power drain. To maximize battery run times reduce leaks and disable comfort features if possible.
  • When you receive your battery pack it may include a small charge. For best performance it should be fully charged prior to first use.
  • Always use the proper DC cord for your CPAP machine. Consult your CPAP machine manual for specifications.

  • not lightweight

    Worked fine, but not lightweight or compact - particularity when packing the charger unit. At my settings, lasted two nights - need a sationary source to recharge, which takes 8+ hours.

  • Pathetic

    The battery pack and it's charger would just fit in the small case provided - but the necessary Resmed S9 24volt connection is bulkier than those two items put together. Stuck with this stupid product, I decided to try it. The fully charged battery pack was tested with the S9 humidifier off. I was awoken after 5 hours due to zero pressure - flat battery! I am extremely annoyed with your product, the price is ridiculously high for what it is, it does not work for even one night's sleep!

  • Poor quality interrupts power frequently

    All through the redeye flight to Ireland the power would cut out. If I held the cables perfectly still I could get it flowing, but I couldn't rely on it staying perfectly oriented. I would drift into sleep, move my hands, the CPAP would shut off, and I'd wake up. I'd then spend several minutes getting the connection to work again. I will return this as soon as I get back to the states.

    The battery itself is compact and light, but the converters make the overall battery pack somewhat bulkier and heavier than I expected. I have not yet used it, so I cannot comment on how well it functions.

  • AWESOME!!!

    I purchased this setup plus an additional battery so that I would always have a backup because we go camping for about 10 days every year and I wanted to try and use my humidifier too. I liked the reviews so I was hoping it would be a good setup for me and it exceeded my expectations. The humidifier did drain the battery faster than just using the CPAP as mentioned, but I had my second battery so I just rotated them out charging one every day of our trip. Fantastic purchase at a price that actually makes it affordable.

  • Works as expected

    You will need a Triplite DC to AC converter if using the S8 Series CPAP.

  • Battery Pack for CPAP

    Just as expected. High quality and once charged I tried it. Ran silently for over 8 hours. I went to recharge it and it was still fully charged! Customer service is excellent and helped answer all my questions. Thank you from a satisfied customer.

  • Battery Pack

    Bought this for one of my patients who is on a bipap continuously. Her family was in heaven because they could take her outside, in the car, to the store, and to her benefit to raise funds for her terminal illness. It works very well and is easy to use!

  • Camping Experience

    The light weight battery pack for my ResMed CPAP machine was everything promised. It was used nightly on an extended camping trip for over a week and povided two nights worth of battery life before needing a recharge, when used without the humidifier.
