    Is there a difference with the output for the two USB ports? I feel like the USB port closest to the driver charges my iPhone 6S+ very slow. I haven't done any times tests yet. Does anyone know the specs of the USB ports?

    Here you go: Tesla Model S Fast Charging USB Port Hack - TESLARATI.com

    Summary

    I confirmed that both ports on my Model S charge at a rate of 1 amp, and not the 2.1/1 amp that some forum members (myself included) have previously reported. Actual measurements indicate that the PortaPow device is useless in the Model S. Skip it.
    My recommendation is to get a good USB car charger that’s capable of charging at the maximum 2.1A rate. You can pick up a decent charger for under $20 that will actually do the job.

    Any info on charging rate from the phone mount USB port in the center console? My phone thinks it is charging but it seems to me like the rate might be 0 or even negative.
