## Description

Please confirm your device voltage before you use this power bank. Low voltage devices can't be plugged into the high voltage output port. Talentcell power bank is designed specifically to integrate with our Light bars, Flexible LED Lights, or 24V/12V/5V DC electronic device. The power bank can be recharged without limitations, as the power bank is designed for a slow charge process (5 hours for full charge), which helps the battery pack last longer. Specification: Capacity: 3.7V/35000mAh 129.5WhInput: 29.4V/0.95A.Output: USB: 5V/2.4A Max. DC port: 24V（29.4V-21V）/5A Max. 12V/2.5A Max. Package content: 1x 24/12/5V power bank 1x Power Cable 1x AC charger NOTES Do not use the power bank in places with high humidity or where it may be exposed to wet. Do not modify or disassemble the power bank. Do not throw the power bank into fire or water. Do not place the power bank during charging on flammbable materials such as in the bed or carpets.

Review: Resmed airsense 10 engineering notes - The rated input voltage for the air 10 CPAP is 24 volts. This battery outputs anywhere between 20 and 29.4 volts. If you are concerned, like I was about the input voltage, there are a few solutions. You can buy two of the 12 volt batteries and hook them in series. This will give you a max voltage of about 25 or 26 volts instead of 29 volts. Another option is to use a DC to DC converter like I am doing. There is a converter made by Bix power specifically for the air sense 10 for about 59 bucks. You will need a few adapters and/or be able to solder to get it all hooked up right but in the end you will have a superior product for about half the price of most others. This will allow this battery to be used as a UPS backup power instead of just for camping etc. It will switch automatically if power is lost in the middle of the night. You will never know that power went out until you get up in the morning!
Review: Works well with ResMed AirMini - I bought a couple of these for some serious backpacking, and, as batteries go, I am impressed. With my ResMed AirMini, I got three 8 hour nights out of one battery on the first test with a full charge. (Your performance may vary depending upon your settings). I previously purchased a Medistrom Pilot-24 battery for travel, which cost about four times as much, and has an expected life of about half one of these. They use the same cable, so I didn't need to purchase anything else. The only thing that I was disappointed with was the recharge time, but still, after using it three nights in a row, I recharged it fully over the next night. I may get a faster charger if it is safe to do so, to enable a quick charge at a restaurant off the trail. I'm a happy camper!

### ⭐⭐⭐⭐⭐ Worked for me to have a battery backup power for CPAP machine.
*by L***T on October 2, 2025*

Bought this for a battery backup for a CPAP machine that requires 24-volt DC power. After finding the correct power cord that connected it to my RESMED Airsense 11. With tube heat and humidification shut off, the battery pack powered the machine for more than 24 hours. It is a much more cost-friendly solution, with the price of the battery pack and power cord, I was all in for just over $100.00.
