We needed a 3A USB socket for charging mobile phones, GPS and iPad in the car. Wanted it to be hidden while easily accessible. If it would be of interest. This is the way I arranged it. 1. Bought a 12V to 5V (DC-DC) (3A) converter on eBay. 2. Connected the cables behind the 12V outlet in the glove compartment. Black (ground) to black and red (+) to red (light) on the 12V outlet. I want to be able to charge when I have the lights in the car on. 3. Glued converter and plug firmly under the glove compartment. See pictures.
