I have heard it mentioned that the current rating for a USB charger is dependent on the current rating of the USB port itself; ie a Type A connector has to be rated for 2A on a charger that says it supports 2A.
How true is this statement?
Looking on DigiKey, I am having trouble finding USB Type A connectors with a current rating of over 1.5A. There are some that list 1 to 1.5A; many have no current rating at all!
Where are these high current USB ports for charging and how can I find them?
