Portable Outlet Universal CPAP Battery

I can't say how disappointed I am in this product. It worked for less than a year with only a few uses on camping trips. This was an expensive purchase to only work a few times. No warranty and CPAP.com won't refund. I won't likely buy expensive accessories anymore.

I participated in a Civil War reenactment that had me sleeping in a canvas A frame tent for the weekend. After 15 hours of use, I still had two blue lights on this battery at an average pressure of 8-10 during the nights.

I used it with my home CPAP and travel CPAP and the times were as claimed.

Hello, this is the truth, dream station, humidifier on 4, heated tube 0n 4, 3.8 hour battery dead. humidifier on 0, heated tube on 0. battery last 9.2 hours still at two bars strong. humidifier on 1, heated tube off 6.9 hours battery life. So you can see both the heated tube and the humidifier eat the battery up fast. I slept fine with humidifier, and heated tube off.. great power source I Highly Recommend. Camping here I come!

I have purchased products from CPAP.com for years. Because I live in the country with electricity outages that are common, I had to have a battery back up and the first one that I purchased was around 10-12 years ago. I have had a couple prior to this most recent purchase. CPAP.com was very helpful in finding the right set up each time I needed to replace it. This is a great product that can be used with any electronic device. I recently used it to keep my computer charging when I was away from home! I love that I have the emergency back up for my CPAP that is versatile to use for other purposes as well.

I purchased this battery for a weeklong houseboat trip. The first time I tried the battery at home after a full charge - it ran all night... no issues. The first day of using it on the houseboat it ran for 7 hours...then died. The most I've gotten from this battery after a full charge is 7 hours. Even tho the first charge...at home lasted over 8 hours and part of a second night. Way too expensive for the value and longevity of the battery.

Received promptly but went downhill from there. Charged pac for approximately 6 hours. Lights indicated it was fully charged. Got only four hours use before CPAP stopped. This is not even close to the 8-12 hours advertised. Very dissatisfied and disappointed.

After letting the battery charge fully I plugged it into the AC power cord for my CPAP machine and turned it on. The CPAP unit came up and operated normally, both the blower and humidifier seemed to be working as expected. If the power goes out I should have no problem getting a good night's sleep.

I have been looking for a product for when the power goes out that would allow me to use my CPAP through the night and this product does that. Based on the variables that the manufacture identifes which impact the batttery's ability to last through the night, such as pressure, humidifier on/off, and altitude, I was interesterd to see if the charge would last all night and if so how much power it used. For reference, I use a Resair APAP that varies the pressure as needed (from 8-18), I had the humidifier on my usual "1", I live at sea level, and used it for a little more than 7 hours. The charge level is represented by 4 lights with no specific percent indicated, so in the mornong one light had gone out which I am interpreting as roughly between 25% and 50% of the battery was used for the night. It took several hours to initially fully charge it and several hours to recharge it. I would recommend this product to anyone who is looking for a reliable power supply for thier CPAP during power outages. As a suggestion to other customers when writing your reviews, if possible, please share the above variables that you used so that other customers can compare to their variables which may help them get a better idea if the product is right for them.

I like the fact that this battery will run any cpap machine that has a wall outlet plug for the power supply. It will last at least 8 hours, maybe more because I still had 2 led lights after 8 hours.

So far it's just what I expected. I am leaving Friday for a weekend backpacking trip in the back country of the Sierra Mountains and decided to try this out so I wouldn't have to go without my CPAP machine. Currently I'm testing it in the comfort of my own house. Have used it for 3 nights on 1 single charge and it's still going. I sleep about 5 hours a night so I guess it's lasted 15 hours so far. I'm going to keep going until the batter charge is out so that I'll know how many days I could manage when backpacking. As for functionality, it's just as advertised.

Worked for 2 nights, 8 hours sleep each night, from full charge. I did not use the humidifier on the CPAP. I was so grateful to be able to go camping. The only issue was the charger for the battery was not in the box, but customer service sent out a replacement battery that day, and I was able to order a charger off of amazon so I could still go camping.
