usb C charging??

[Crazybutlazy]

Anyone have experience with buying a USB C wall wart for charging their laptops? I have a Dell XPS 15 9560 and would like to keep a compact wall wart to keep in my bag, as the regular charger is a little bit cumbersome. Does anyone have any recommendations?

USB C ports will only charge/power a laptop if the port is configured to accept input power.  Also, the USB C power adapter needs to be rated for however many watts the normal adapter puts out if the USB C port meets the previous requirement.

 

Also, AFAIK, USB C maxes out at 100w.  Most laptops with a dGPU need 130w+.

My work laptop runs off a dock thats connected with a single usb c connection. I would imagine all computers with usb c should be able to accept power?

XPS15 requires the Dell dock for the USBC charging

This is not the case.  I have two laptops that will not accept power over USB-C.
