USB-C charging specifications
#1
If I buy the PineBook Pro, would like to be able to charge it over USB-C, so I can use the same charger I use to charge my smartphone. So what are the charging specs? Is it compatible with Qualcomm Quick Charge 5V/9V/12V? Is compatible with USB Power Delivery? In case I don’t have direct access to wall charger, would like to be able to use power banks, the same I use for android and iPad without having to charge with a barrel connector.

There are at least 5 versions of Quick Charge, which one does have the PineBook Pro? Specifically if it only supports 5v or supports further higher discrete values.

I'm sorry, i can't recall the specifics, but if the charger you have can supply 5V/3A you should be fine.

@zxorg, I've updated the Wiki to indicate that our Pinebook Pros charge from 5 volt USB-C.

And @tophneal is correct, 3 amps would be best. Some of my older USB Type A chargers only do 2.4 amps, so I keep that in mind if I ever have to use one of them.

@Arwen thanks for the Wiki update. Actually yes, 3A is quite high amperage for 5V, because high amperage generate lots of heat. Voltage drops along a lengthy cable can be more than noticeable, for example going from 5.3v to 4.6v if the cable is 1.5~3m and the copper section is not high. That's why laptops with PD only allow as a general rule 20v@3A, to reach maximum specs of 100W@20v@5A you need certified cables so there isn't any USB disconnect or self-ignition fire hazard. And GaN chargers are preferred due to more compact size.

For next PineBook Phone/laptop generations I strongly recommend accepting higher voltages in return for less amps. Sleepy

So, for the understanding of a non-technical guy, this would mean that using the USB-C power adapter of my Chromebook (nominally 45W) would not blow up my PBP?

I have used a 65W GaN charger without any problem with the PBP.
Under normal circumstances they do a "handshake".
Otherwise you could already have problems with voltages like 9V, 12V, 15V and even 20V.

Most compatibility issues I have heard involve Apple devices and chargers.
But it still shouldn't blow up the PBP, it just won't charge.

OK. I'll risk it. On your head it is....

Let us know if I can keep my head. ;-)
