11.1v 10.4Ah Battery Pack For C115 CPAP Machine Wholesale

I needed something to power my CPAP machine while camping. With a full charge, I was able to get 20 hours of operation - 2 1/2 nights worth at 8hrs/night. Not a great option if you're planning to backpack for several days but it's great for a few nights or if you have access to power for recharging. The fact that you have to use your machine's power supply is a little cumbersome but I knew that from the reviews so I wasn't surprised.

Nothing but good things to say about this... I ordered this battery on very short notice due to last minute business plans in Asia. Though I opted for expedited delivery, their domestic warehouse was out of supplies. I was immediately contacted by a rep, who worked with me (and a different warehouse) to ship me a battery on time... With enough room to test the battery last night prior to my flight tomorrow. Great quality battery and construction, and very easy to use...

I am getting about 17 hours of use out of the battery. Not quite enough for the 3 night camping trip I purchased the battery for, Recharges quickly. Was a little disappointed that it did not come with its own charger - you use the power supply for your CPAP to charge.Appears to be very well made. Performs as promised. Recharges pretty fast and provides reliable power to my Phillips CPAP throughout the night (uses about 1/3 of stored power each night -- without humidifier/heater). I would recommend to anyone using a CPAP and looking for portability.

I am a little disappointed in the Battery's performance. It lasted about 14 hours. and the alarm sounded in the middle of the second night. This limits me to never being further away from my truck or an electric outlet for more than one night. On the bright side, it fits easily in my Kelty pack along with my ResMed CPAP.  Works great. Make sure all the power drainer of off, I left the warm up mode on auto but turned everything else off. Battery last 3 hours and an alarm woke me up. Thought the battery was defective but checked my cpap settings and tried again on the second night. I took it on a 4 night camping trip and it worked great, about a 50% drain on the battery so I'm pretty sure 2 nights would be ok. I also bought the Pilot 12v charger, it topped off the battery in an hour.
