Y'all do know there's a second 12v power port in the console under the so-called armrest, right? Don't think I've ever used the USB port, honestly

 

That one is either for passengers or it doesn't get used. The one in the dash is being taken up by a dual port USB charger. It would be nice to make use of the USB port that's just sitting there, since I either listen to the radio or use Bluetooth.

 

One item to take into consideration... IF you are using an off-brand (ie cheap) micro thin cord for your USB connection... therein lies a problem. Elemental electronics. Many off brand cords use the minimal sized wiring, cost considerations and to make it attractive, in their cord construction. Now, I am not saying go out and get a USB cord that looks like an outdoor extension cord... but any cord smaller than 24AWG will not be able to give you the current flow necessary for a "fast charge."
