We always recommend you check with your airline before travel on what restrictions they might have in place.

      • Using a heated humidifier with your battery pack is not possible. Please disconnect the H5i Humidifier from your Airsense10 whilst using the CPAP battery
      • Always use the power supply provided to recharge your battery pack. Using a non-approved recharger may damage your battery.
      • Always use the proper DC cord for your CPAP/BiPAP machine. Consult your CPAP/BiPAP machine manual for specifications.
      • If you wish to charge the C-150 from a DC source such as a 12V car socket you will need to purchase the DC Charger from our store.

  1. 17 Hours over 2 nights with no worries! Now able to handle multiple flights on a single charge. review by The Aussie Viking on 5/23/2017

    I have flights coming up Perth-Brisbane (7 1/2Hrs) then Brisbane-Vancouver (13 1/2Hrs) where the standard battery would be flat if I was not able to recharge it at the Brisbane stop. To test it's capacity I did 8hrs sleep in aircraft mode (humidifier & tube heating turned off), then 9 Hours on the second night. Although the battery was down to 1 Bar from the fully charged 4 bars, it still had reserve in it, as it wasn't down the final Red square.
    An absolute must for long flights to distant destinations, as I don't want to fight jetlag whilst waiting for a battery to re-charge. It's certainly up to the task!

  2. Very good battery review by lonely traveller on 4/7/2016

    This battery pack is unlike anything on the market! You know you have a good product when there is a wait to get one haha. Luckily got it just in time before our camping trip. The battery i must say is brilliant. It's very small which makes it great for travel as it fits in the bag. Get one!

  3. Kick Ass battery! review by Lonely planet on 10/13/2015

    If you are looking for a great battery system for your CPAP machine then look no further! This battery is very light and yet it runs my machine for two nights before i need to recharge it. I also purchased the DC charger so i can charge it up whilst driving in my RV. The battery works straight out of the bag so you don't need to go and buy all that other rubbish that other companies tell you you need. The products are pricey but what in the CPAP world isn't. I love this product
