If you’re like me, you have dozens of USB-A and USB-C cables. There are all of various quality, but I have no idea the history of each one. A lot of them came with other products and are total unknown quantity anyway.

Is there a tool to quickly test how good each cable is? Either a software or a hardware tool. Ideally it’d be nice to see something that can measure the power as well. Some charging cables are capable of fast charging, and some are not.

    I wtf’d that you could do 100W w/ USB… Then I can see that new specs are to allow 240W.

      Yeah, that’s pretty recent. All my chargers are 100W or less. I think the 240W is achieved by increasing the voltage to 48v and keeping the current maximum to 5A.

      Well you can power things like egpus, monitors and gaming laptops soon. Very neat actually.
