Respironics Universal Portable CPAP Battery Pack and Charger

After initial charging at home, used this for a 3 day tent camping trip. It worked great! I turned off the humidifier as others suggested to minimized battery use, and it worked great. I now plan on trying a backpacking trip. Thank You!!!

Haven't used it yet except to see if it actually works with my machine, but it did. I trust it will provide the needed power should my electricity go out.

Battery pack for wife's AVAPS machine so far works great and makes going places or used during power outages much easier.

I used the portable battery pack for a hunting trip to Colorado high country in freezing temperature. I worked fine for 6 nights getting minor recharge from a small solar panel during the day. The pack was completely recharged and operated for another 3 nights without being charged. The pack was used to run REMstar Auto w/CFlex without the humidifier. The unit did what i needed great pack.

We lost power for six hours on Jan-31 and I got to thinking, what if something really bad happened. So I ordered this battery, and sure enough we got hit by one of the big snow storms, and lost power for 58 hours, and this battery performed like a champ, I have a Remstar M series CPAP @ 12, normally using a humidifier. 3 nights ~21 hours (w/o humidifier) and it still had power to run my grandsons nebulizer for his asthma.
