How to display laptop charging speed

cn flag

I have a laptop that charges via USB-C and it can be charged by connecting it to the USB-C port of my desktop. But I would like to know at which wattage.

Is there a command to display at which wattage a laptop is charging? This might also be helpful when comparing different charging bricks and USB cables.

This isn't a full answer... but... usually the wattage is simply listed on the charging brick. E.g., my USB-C charger says 65W on the side, and that would be the max for the charger. This wouldn't be helpful to you, but is a reasonable general answer. As to getting the _current_ power draw in software, see [this question]( on Unix & Linux SE.

cocomac: My question was about charging via the usb-c port on my desktop, so it's not as obvious where to look it up as a charging brick. But even with a charging brick it's nice to be able to verify how much wattage actually goes through, since it also depends on the cable which normally doesn't have any label.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
