FOSDEM 19 Announcements Discussion

[CampGareth]

Thanks Robbie, but Quick Charge is Qualcomm's proprietary charging implementation; I'm talking specifically about the USB Power Delivery standard, as proposed by the USB Implementers Forum. Since its implementation, one of the problems with USB Type-C has been insufficient enforcement, which leads to compatibility issues.

This article outlines some of the pitfalls: It’s 2018 and USB Type-C is still a mess

Using a dedicated power port isn't necessarily a bad thing, but I can imagine a situation where I lose a charger with a proprietary barrel connector while travelling (DAMHIK) and using a USB Type-C charging cable would be a useful fallback. 

Google engineer Benson Leung has achieved some notoriety as a USB Type-C investigator — including destroying some of his devices in Type-C charging testing that went wrong. 
Here is the tl;dr version from Benson: USB Type-C™’s Configuration Channel

So, my questions are:

1. Can the Pinbook Pro's USB Type-C port be used for charging?
   
2. If yes, what charging voltage range is supported?
   

1) Yes the USB-C port can be used for charging
2) 5V, unsure about anything else.

My guesses would be that the barrel jack and power pins of the USB-C port are connected together, and that 5V 3A charging via USB-C (no negotiation required for that) will be the fastest charging we can do.

Anyway I'm super excited for this as it'd be nice to have an ARM daily driver laptop that is fast enough for a 1080p youtube video and has simple options for battery life extension. I just hope the keyboard's fairly good, I've asked a friend at FOSDEM to visit and check that aspect out!
