USB charging is shrouded in mystery -- which is a bit ironic, given that almost all of us rely on USB charging of our smartphones and tablets on a daily basis.

We will also be taking a look at a new device, called the Practical Meter, which finally gives us insight into the arcane world of USB charging.
