I just figured USB-C would have been designed to beat out what I see at an older, 'inferior' device... guess not.
Rock N Roll, I'll use the barrel @ home and can lug around my USB-C battery pack thats also a 65W charger for on the go. Thanks for the deets, folks.
I don't know why USB-C on PBP takes less current than the barrel port, but as discussed in some other threads 15W is a limitation of how the battery charge controller is configured in PBP, possibly for heat management reasons. As to USB-C being designed "to beat out what I see as an older, 'inferior' device" - USB PD standard maxes out at 100W, every laptop manufactured after 2009 that I own (except PBP) can easily reach 120-150W+ power consumption, all use barrel plug on a 170W+ AC adapter. The main driving reason behind the use of USB-C as a power delivery mechanism is not providing more power than barrel plug, but the same as the reason for dropping analog audio port in the latest phones and using USB-C digital headphones instead - miniaturization, drive to reduce the number and size of ports to make the devices thinner, to dedicate more of their volume to battery and surface to screen. If you have any USB-C peripherals - be happy you have a barrel charger port on your PBP in addition to a single Type C port.
