This is all about AMPS available on the port being used as ALL USB1 and 2 ports are 5V +/- 5% (since there is no such ting as a negative voltage drop
, 5.1V is best)
The basic USB port on your PC will supply
up to 500mA, then it shuts off. Some devices detect this port and switch to a "slow charge" mode to keep from tripping the over current device.
BTW I have lost track of how many I have. Ranges from .5 to 2.1A per port.
Car (12V), computer External powered USB Hubs, Outlet strips with charging ports, a couple of Samsung Tablet chargers, Phones*, BT Earpiece chargers*
* cord attached.
My Laptops take 19V. I even have a 12V cord in my road warrior bag
for when I need to charge that between stops
