Tech Nerds-think this battery setup will work for Transcend Micro?

Post by johnbrain » Wed Mar 27, 2024 1:14 pm

Hi. New to forum and relatively new to CPA use. Especially traveling.
Using my Transcend Micro in my Sprinter off the inverter really drains my house batteries and there isn't a 12V DC adapter available for it. I may have shopped differently had I factored in 12V use but it works great in hotels around the world. The limited battery options are very expensive or not compact or both.

Running this by you.

The Transcend Micro Poweraway battery outputs as follows:

Rated Output: DC 14.8V, 2.7A


Would a 14V USB-C to Barrel trigger cable (currently marketed for the Transcend Micro) running off a 24000mAh Anker PD battery with following specs work even for just a few hours? Charging the battery isn't an issue

USB-C1= 9V ⎓ 3A / 15V ⎓ 3A / 20V ⎓ 3.25A / 3.3V~16V ⎓3A

Comment from one of the really expensive CPAP battery backup makers.

"Q: Is the DC output port a fully functional usb-c pd port? In other words can it provide voltages between 5 and 24 volts depending on the cable used?

A: Yes, it is. But please be advised that the DC out port is only designed to provide power on CPAP/BiPAP Machines. You may consider using the USB out port to power or charge other devices"

Thanks in advance. Really trying to solve this riddle without spending a lot for a singular use item.

from my research online i need this solution as well. i'm trying to get a battery that will do 7 or 8 nights of sleep. i think you're on the right track though from what i'm researching. the "trigger" cable is key. i didn't even know what they were til today. but that trigger feature (for those that don't know) allow a device to be powered by any of those usb-c power banks. without it, the power bank doesn't know it's compatible and won't send power.

I use this as my backup battery for my cpap which is a resmed. The inverter is for the fridge if I loose power for a long time. It runs my resmed for 30 hours with the heated tank and tube on. In my case the resmed PSU is a car 12v power outlet. Depends on what you need output exactly it can be direct to the battery, loose the current shunt and.monitor.

Cor my cpap I need 270ish watt hours per 10hr night. My battery has 1280watt hours in it. My draw is about 2.5 to 7 amps as it cycles the heaters off and on.

The whole thing fits into an old sewing box I got at a thrift shop for $2. Except the charger is outside the box. Total weight minus the inverter is about 25lbs or about 1/3rd the weight of a car battery.

All of the parts except for the inverter cost $498

Battery life of the type used is about 15 years if used nightly and charged daily.
