USB loads:




There are lots of "USB load testers" for sale. They vary all the way from two resistors and a switch on a board
with a USB-A port on it, all the way up to fins and fans and digital displays. But they're a good way to make
sure your USB port is working, and to verify operation (and capacity) of USB power banks.
