You might want to check out the Omnicharge https://www.omnicharge.co/ products. They have a DC out port that has configurable voltage. So you can set it to 15V and not need all the extra adapters. I just put together my own setup with Airmini and Omnicharge Omni 20 and will be taking it trekking (not at altitude yet) in a couple days.

Omnicharge is having a sale right now: https://www.omnicharge.co/summer-sale/? ... _sale_2019

I got a Omni 20 (2018) model, solar charger, and case for $220 USD shipped. I likely don't need the 120V on it, but at $100, it was hard to pass up.

I recently posted a battery solution for HDM Z1 cpap using battery power banks that output 15V via usb-c using a usb-c pd trigger cable. mech18's original post got me thinking and searching to see if recently technology improvements could reduce the number of parts needed.
