Hello,
I am designing a new USB charging hub for a customer. The customer wants it to charge the newest tablets and iPads @ 2.1amps per port. Charging only.. No data communication. I am struggling to find PCB Mount Standard-A USBReceptacles rated for 2.1amp charging currents. All models that I have found are either rated for 1amp or 1.5amps. I have also talked with Molex, Millmax and Keystone engineers who said that they dont have anything rated @2amps, but they will give me a sample of their 1.0/1.5amp model to try.
I am starting to think that "officially", for a given temperature rise, they are rated for 1 or 1.5amps....BUT.... people run them @ 2.1amps if you accept that it might run a little hotter....and then I should provide adequate PCB heatsinking.
Ooh, I just discovered several USB 3.0 connectors rated @ 1.8amps, but nothing over 2amps. To my surprise there is not much discussion about this. Any input would be great. Thanks!
