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 case of a power outage or other unforeseen circumstances, EXP PRO batteries are designed to keep you powered up in any situation with "Pass Through" technology. If there's a power failure at home, the EXP PRO takes over AC power automatically.

In the event of an extended loss of power, we offer a 60 watt solar panel that can easily be unfolded and placed outside during the day to top off your battery charge.
