I have USB b cables that I bought at a dollar store that have never had problems charging, syncing or tethering. I started using them on my Mogul and the TP2 seems to be no different.
I have a bunch of car cigerette lighter USB adapters too, I just use a standard USB B cable and plug it in if I need to charge in the car. I also have wall adapters for the cigarette adapters.
