If you have more than one person in the car with you, that means that more than one person is going to want to charge their phone. But you're using your GPS and it's sucking your battery, and they want to play their music.
Solve all your problems by getting a mount that actually charges your phone. You can free up that USB space for things other than phone charging purposes by easily installing this guy into your air vents and letting it charge right up.

This is the best car mount/charger i’ve ever used, especially since it allows me to use my speaker cable and charge my phone at the same time. My husband and I now always fight over who gets to have their phone in the mount...LOL
