For those who don't know, USB charging is a lot slower than A/C (wall outlet) charging. This thread goes into it well: http://androidforums.com/htc-evo-4g...-have-dramatic-difference-charging-times.html That said: anyone know a way to up the amps from a USB port? I'm especially interested for this in my car, where I have a USB port from my audio system, and would really like to charge my Incredible while I use it as a GPS. Any tips for this? I know "get a car adapter" is an easy solution, but I'd prefer avoid that if possible.
