look at the plate on your cpap to see how many watts and amps it draws. most of the battery packs are rated in amp hours and surge watts so you should be able to figure out if it will work.I recently became aware of these Jackerys. I need one to run a CPAP machine till they repair my nose. Recently found out all of my breaking my nose dozens of times has caught up with me.
You know about the Jackerys? Are they good and last?
