The Lightweight CPAP Battery Pack is a brilliant power solution for people who need truly portable sleep therapy or a reliable backup for use during unexpected power outages. At its heart is an ultra-small, lightweight (less than 1.5 pounds), and powerful Lithium Ion battery like those found in many laptop computers. Providing average run times of 1-2 nights with most machines the Lightweight CPAP Battery Pack really works!

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
Written By: user, Clifton Park 7/31/2016
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.

really pleased
Written By: Hilton G, Iowa 5/10/2016
I bought this battery because we take trips to a deaf school in cameroon... there is often no electric and i need to use my cpap machine. I felt the price was good, really appreciated the free shipping and the speed in which it was delivered! The battery lasted far longer than advertised. Its portable and affordable. Really pleased with this purchase.

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
Written By: Dan J , Falls Church 10/15/2015
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.

I bought this item to use while traveling. Haven't used it yet on a trip, but I charged it and tested it out at home and it powered my CPAP fort three full nights (my pressure setting is seven). I'm very, very pleased. I also like the compact size/weight and the little carrying case. I would like to hear if anyone has had issues getting it through airport security.

Works Great
Written By: Thomas G, Bend 8/13/2015
Just came back from a three night fishing/camping trip. Battery lasted for 21 hours run time on pressure setting of 7 on my Cpap. Very happy with the purchase and very light weight.

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.

4 hours - that's it.
Written By: MR, U.S. 3/28/2015
I bought this battery for my REMStarPro M series. It is supposed to power that model for 12 hours at the settings I use. It has never powered it for more than 4 hours. The battery and charger have been replaced, but that has not resolved the problem.

small battery pack
Written By: JDF, TN 3/4/2015
It says it is lightweight and small, and it is. At first, I thought I did not get everything I paid for, but then realized that yes I did !

Nice Addition for Camping
Written By: Henry, Highpoint 2/4/2015
Our family likes to go camping but it was difficult with CPAP. My wife bought the battery pack for Christmas and we've already been camping this month. It worked great and hopefully will last for a long time!
