Here is a Pinebook Pro question to ask at FOSDEM:
Specs say it comes with a charger with a barrel connector, but it also has a USB Type-C port. Since USB Type-C can usually be used for charging, my question is does it require a 5V charger, or will it negotiate the USB Power Delivery spec to deliver the appropriate charging voltage? Even at 5V a 10000 mAh battery should charge fairly quickly, but if it can accept a higher voltage, charging would be faster. For example, I have a HP Chromebook 13 G1, which charges through the USB Type-C port @ ~14.5 V. Being able to use that charger with a Pinebook Pro would be very handy.

It would be nice to have an authoritative answer, as I wouldn't want to answer this question by trial and error.

A Texas Instruments tech sheet says:
Quote:The USB Power Delivery (PD) Specification describes a standard negotiation process for establishing all
PD power contracts. Although the USB Type-C standard allows for providing 5 V at up to 15 W of power,
following the PD protocol is critical for offering or receiving any voltage higher than 5 V. As a result, any
product that requires or delivers power from 5 to 20 V (15 to 100 W of power) must negotiate according to
a specific set of standardized rules.
