Is there a way to test the data transfer speed of USB cables?

posted 4 months ago

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.
