Why can't my computer keep my phone charged?

[AC Question]

I have a Galaxy S4. I have never had problems before but suddenly yesterday I realized my phone was not charging while connected to the computer. I tested the cord on the wall, and tested another cord on the wall. Both are fine. I'm really not sure if its a computer issue or a phone issue. Any ideas would be helpful. Thanks!

The port might be too weak try another port

It is possible for the ports of the PC to stop outputting almost all power. This happened to my old laptop.
