Powering the P15 via USB Power Delivery

2020-09-15, 21:03 PM

The P53 platform specifications and P15 platform specifications have a curious difference in the port documentation. The P53 specifications say "Power Delivery only supports power-out for charging peripherals" while the P15 specs say nothing other than including the PD initials for a couple ports.


I know Power Delivery has a limit of 100W -- substantially less than the 170W+ the main P15 power supply provides -- but I'm curious if the P15 can use Power Delivery to charge and run lighter tasks. I like having Power Delivery chargers around my apartment as "universal" chargers that work with with our phones, current laptops (T580 and X1C Gen 7), and tablet/convertible computers (an old Pixel C and Pixelbook).


So, assuming I upgrade to Power Delivery chargers that can pump 100W, what can I expect for the P15?

Dear Customer,

unfortunately, ThinkPad P15 doesn't support battery charge via Tyep-c (Power Delivery) port which is the same as P53.

Please use 170W (or 230W) slim AC adapter.
