Pavilion x2 12-b020nr External Battery

Hi, I am searching for a compatible external battery for my Pavilion x2 12. However, I am discouraged by this thread :http://forum.tabletpcreview.com/threads/hps-usb-c-charger-lock-crisis-explained.69523/

 

Looks like HP locked down the USB type-C charging port which only accept HP charger. However, there are times when I am not near a power outlet and on the go. I need an external battery. This also prevented users from passing though power when using USB docks, which is bad.

 

It seems that there is no external battery available for Pavilion x2 12, am I right? Or is there any BIOS setting that allow me to turn off the charging DRM?

It seems downgrading BIOS to F.05 Rev A can disable the charging DRM from the forum thread I linked.

 

Is it true?
