USB vs 12V

So today I drove for about an hour to meet some family for an event. I had my IPhone plugged in via the USB port so I can access my music directly. But since I was using the GPS app, I'm not suje how well it was able to charge my phone. during the even my battery went down to 8 percent and I drove home with it plugged into usb and gps on and it was 11 percent when I got home.

My question is - is it better to use the 12v plug in with a usb connector or use the actual build in USB hub in the car? The car's hub doesn't seem like it provides that good of juice. But I haven't tested the 12v plug method on a long ride yet either.

I'm driving from PA to NY tomorrow and need my phone and gps working during the whole ride...any suggestions?
