I have found the X96Pro easy to set up, well functioning and surprisingly quiet!
I bought it so I can go camping and my initial run time is just over 34 hrs of CPAP use. I like the construction and small size. Glad I got it in case there are power outages due to storms. Love knowing I will be able to use my CPAP anywhere I end up.
This my 2nd Battery from EXPRO and the first lasted over 5 years. So I recently purchased the EXP96Pro and I am extremmly happy with the pass thru abilty for my CPAP. I am using that way so I have peace of mind that my therpy will not be interupted by power outages.
Fully charged, the EXP96PRO lasted for three nights camping with a mini-CPAP machine. It still had slightly under half a charge when I came home. Worked exactly like I wanted.
Have only used it on one trip so far, so I can't comment on long-term use, but it successfully ran my Resmed Airsense 10 as well as recharged two phones, two Apple Watches and a tablet for 3 nights. The adapter cable was fine, and the extra charging port on the adapter actually came in handy.
If you're going to be hanging multiple devices off the battery to recharge, I recommend getting a USB hub with a USB-C connector to the battery, instead of trying to use the USB-A ports.
The design of the neoprene carrying case could use some improvement. When the battery is in the neoprene case the carry handle on the battery itself can not be used; you can't easily tell if the emergency light has been accidentally turned on because the light is inside the case, and there are no ports or holes to allow you to check; and you have to pull the neoprene case down a little bit to see the status LEDs on the battery.
But otherwise, it has worked out great!
