My wife and I were able to run both our resmed airminis three and one half nights on a full charge. We have now used it on two camping trips, the first we started at full charge and ran two CPAPs for two nights without re-charging...It is expensive, but this is now the forth battery I have purchased in an effort to find a battery that would work for our needs, this one worked perfectly for what we wanted (being able to run at least two nights running two cpaps without recharging.) I wish I would have just bought this one first.

I had purchased some batteries in the past and I wasn't too happy with them. I decided to give it one more shot and I bought this one. This battery is amazing! It lasts a while and doesn't take that long to fully charge. My machine works perfectly while it is plugged in and I can use it for about 2 nights before I need to charge it. I'm so happy I finally found a battery I like.

I live in Florida so I wanted to buy a battery to use in case of a hurricane. I looked around and finally decided on this one. I charged it once I received it and hooked it up to my machine to see how it would work. My machine worked the whole night without interruptions and I was even able to hook up my machine to it the next night as well. This battery is definitely worth the price!

Really, it is so nice. I looked at a lot of options, and so many of them either didn't hold a charge very long, or took way too long to recharge, or were so heavy that they weren't practical for me, or you couldn't use them with a solar panel. I mostly boondock, and I had very specific requirements...So, I am one happy person to have this battery....I really had no idea how I was going to be able to travel and camp with sleep apnea and a CPAP.

Do you have a battery backup for your CPAP?

In the event of a power outage or other unexpected situations, EXP PRO batteries are equipped with advanced "Pass Through" technology to ensure uninterrupted power. Should there be a power failure at your home, the EXP PRO battery automatically takes over, seamlessly switching to battery power without any disruption to your device's operation. This reliable backup system ensures that your CPAP machine remains powered and functional, no matter the circumstances.

We also offer a 60 watt solar panel that can easily be unfolded and placed outside during the day to top off your battery charge. This is useful to have in the case of extended power outages.
