USB port not charging iPhone

Did a search but didn't see anything on this.

I have my iPhone plugged into the USB port in the center console. The iPhone is receiving power, as the "charging" indicator is displayed. However, even after a long drive, the phone's charge amount is only increased by maybe a percentage point or two. The USB port appears to give just enough power to keep the phone at its current level, but not really charge it.

Anyone else notice this?

USB isn't always the same for charging capabilities. I suspect that the Volt's USB port just doesn't supply a lot of extra power. I've noticed that some computers/laptops can charge my phone faster than others. And that charging from the wall adapter is almost always the fastest.

Edit: If charging speed is your only concern, you could try one of those USB adapters that go into your power port. I am willing to bet that'll charge faster for you.
