Lack of USB PD support is only a (small) part of the issue. The main bottleneck is the battery charge controller [configuration], unless that is addressed USB PD will do jack squat.

No,, I just spent an hour, with a slightly lower quality vernier,,
3.3 x 1.25
It is quite hard to find smaller wires to measure ID (of plug),,
for sure,,,1.3 will not go in, 1.2 slightly loose
(a selection of beehive nails,, frame nails)
More measurements, more verniers, not consistent
probably type H,,,,3.4 x1.3

I got regular cable from a random supplier 3,5mm x 1,35mm (type H).
Fits perfectly - and barrel port takes 2.8 amps with 50% battery.

And USB-C in pbp supports PD and Quickcharge --> https://wiki.pine64.org/index.php?title=...wer_Supply

To clarify, I believe PBP USB-C port only supports default USB 3.1 charging at 5V/3A (15W) it doesn't support negotiation of V (up to 20V is possible if PD is supported for 60W and up to 100W with a designated EMCA cable). PD, or power delivery is synonymous with quick charging but requires above the default 5V/3A -- which is not available as far as I know, with PBP.

And has been stated, barrel-jack power supply draws more A compared with USB-C -- when power is critical, barrel-jack > USB-C.

IMO there is a systemic design weakness in PBP (and PinePhone during convergence) on power consideration.

No doubt about it.

Power supply specs from the wiki  "USB-C 5V, 15W PD quickcharge" seems incorrect. If it's fixed at 5V then it's not "PD".  Dodgy

However the "quickcharge" functionality can be activated with the  "sudo shudown now"  command.   /s  Big Grin

Is charging noticeably faster? Does the device get hot it any other noticable differences?

Here's one method I use to help with the slow charge rate:

screen_off.desktop:

Code:
[Desktop Entry]
Comment[en_US]=
Comment=
Exec=sleep 2s && xset dpms force off
GenericName[en_US]=Use xset to blank the screen
GenericName=Use xset to blank the screen
Icon=composite-track-preview
MimeType=
Name[en_US]=Screen Off
Name=Screen Off
Path=
StartupNotify=true
Terminal=false
TerminalOptions=
Type=Application
X-DBUS-ServiceName=
X-DBUS-StartupType=


Put that file in your panel to kill the backlight when you don't need it on.  Smile

I think I just got the joke. I'm slow!

K, the first time I actually played along with this, the second time I just kept quiet, but now I'm actually getting a bit annoyed...

Without PD USB can deliver up to six unit loads for high power SuperSpeed devices, where the unit load is 150mA on USB 3.0 (SuperSpeed) and 250mA for multi-lane SuperSpeed. That means without PD USB can deliver up to 7.5W. USB PD was developed specifically to standardize the way to deliver more than 7.5W of power, and than includes 15W, the maximum power deliverable without increasing voltage. So technically 15W delivery in PBP is USB PD, compliant with revision 2 or 3 of the standard, though saying "quickcharge" is indeed a bit of a misnomer since that would imply a different proprietary technology by Qualcomm that predates USB PD standard and AFAIK is available only on their Snapdragon platform.

That said, IMNSHO 15W is barely adequate for PBP.
