Electronic devices sold in the EU must have USB-C charging ports by 2024

In that case, I suppose that a USB-C plug would be able to charge a laptop. Initially, I found that hard to believe. After all, most laptops are charged by 19 volts DC or thereabouts, not 5 volts, so a switch to USB would mean more current, and a need for thicker wires.
My work laptop can charge fine with the current spec USB-C PD that supplies up to 65W. Macbooks have had this benefit for many years now as mentioned by another poster. As I said, it just needs better cable labelling because they are not all equal.

I'm more worried about counterfeit cables. Even companies with the highest level of quality control release defective products. 240watts is just too much power. They raise the voltage because it can't handle the amps. Higher voltage means increase chance of sparks. All you need is for some ***** to use a gas station cable to power a laptop. Also, what's wrong with barrel connectors? I use barrel connectors on all my home electronics projects.
FYI, higher voltage is safer than higher ampage. I was taught this at high school level physics. https://www.thespruce.com/amperage-not-voltage-kills-1152476

Yes but devices need higher amps to actually charge and run at the same time. The reason you'd want to keep voltage down is to keep the risk of an electrical arc down as much as possible.

Imagine taking your USB-C cable out and it arcs to a data pin, completely destroying the USB controller on the motherboard or worse.

Yes, I went to high-school, too. As I said, higher voltage increases the risk of arcing. You either get heat from amps or arcs from voltage. USB-c is great for small, portable devices but I don't see people taking out there laptops 100 times a day to check their Facebook.

As much as I loathe apple, their mag safe connectors is one of the best connectors ever made. There is no objective way to say USB-c is better than magsafe. Create a separate universal standard for laptops to reduce e-waste. USB-c isn't the end all be all of connectors.
