This battery is pricey enough to be an investment, but well worth it in my opinion. I was running my Respironics System One machine on it for two nights at around eight hours a night and it still had juice left. It's pretty heavy to be toting around in a backpack, but that isn't a concern to me. I would have given it five stars, but it is pretty slow to charge. By Dave A, Jackson, MS
I slept like a baby camping
I was sceptical that a battery would work. I could not be more pleased. While it is heavy, it works perfectly. I used it for 3 nights without recharging or problems. Very nice product. By Kevin K, Bermuda Dunes, CA
Long life battery
The battery pack works great during a weekend camping trip. Now my wife can enjoy camping/sleeping better. By Gary K, Lakewood, Co
Long Life Battery Pack
This product is very large and heavy (11 pounds). I was expecting something that would fit into a suitcase and run my CPAP for a couple of nights without power. This looks like it could start my car. By David B, Richmond, VA
Works great! Wow and Fantastic customer service from Cpapxchange!
Hello, We had some troubles with this battery pack at first. But Cpapxchange customer service was great at helping us learn about the airplane mode for my wife's ICON cpap machine. When running in airplane mode the battery last 9+ hours. Fantastic! Very happy now with this product and we're back to enjoying camping trips just like we used to. Thanks Cpapxchange!!!!

I successfully used this battery camping last summer and expected the same good performance camping this summer. Charged the battery until the light turned green on the charger and set off for the mountains.
Sadly, I neglected to notice on the website that the battery needed to be recharged every few months; mine sat in the closet for a year unattended. The battery failed to work, giving me a miserable 14 nights sleeping at camp.
If the battery was not accepting a charge, the indicator light should not still show green. I accept the responsibility for not charging it as I was supposed to, but Respironics should modify the light display so it remains orange if the battery does not charge. The one-year warranty has already expired so I have no recourse but to buy another battery. By Unhappy camper, Upstate New York
effective backup in a crises situation.
Product does what it says it will. However while the instructions don't specify this, you really should FIRST fully charge the battery for 4 to 8 hours PAST the point when the green light comes on indicating a fully charged situation. This gives you the most usable backup power. Doing this and running my machine at 10.5 CM pressure the power lasts about 10 hours. Wish I could get longer but that seems to be the maximum and will at least get me through a long night. I recommend this product. By Pizagno, Buckingham, Pa
Long Life Battery Pack
Small enough to be carried easily, yet powerful enough to supply my high-pressure CPAP for more than a long night. A bit too heavy for travel purposes, but my purpose in buying it was to enable me to sleep through power outages, and it more than does the job. By Gene, Gaithersburg
