sadly NO unless the GC is different than the Durango-
I played around in my Durango with an amp meter-
Wireless and/or USB phone charging
short version is front is like 1.5 ish and rears (while apparently 2 different circuits) are about 1.0 each.
And more importantly you need the "right" cable to max them out. Basically from my understanding of USB if you use a data/sync cable then the device will attempt to negotiate with the host. The host will supply 0.5 amps as the default amount and then depending on what USB version it can provide other higher increments. I used an amp meter with a data cable and my android phone and NONE of the 3 ports are smart enough to do the proper negotiation to get the phone anything beyond 0.50 amps.
this cable will draw every last bit for an android phone:
the same manufacturer has an adapter on amazon that will apparently do the same for apple products.
If you want the full 2 amps then a cigarette lighter adapter or a 110 wall wort is what you'll need.
