Comment on Is there any reason not to charge my laptop with a USB C phone charger?
ji59@hilariouschaos.com 2 days agoI think there should be written somewhere what the computer needs. For example 20V 3A ~ 60W. I don’t know how much voltage the super fast phone chargers have, but looking only at power isn’t enough. Just for curious readers: I noticed some annoyance with my laptop, it has 100W mode, but only with the original charger. So just plugging it into a dock with original charger attached limits the laptop to 65W only. And if I tried (mainly out of curiosity) charging with an insufficient phone charger, CPU switched to 300MHz and everything got very laggy. The same thing happened when I connected two of the USB ports together :D

The required input for the computer is usually inscribed on the chassis at the bottom. However, the text is usually faint and can be easily rubbed off after the computer has been used for some time. Mine says 20 V 2.25 A.

There are also supported outputs on a charger, and usually the maximum power output mode is the same as the optimal input for a laptop it came with.
