Just got this dedicated battery charger from eBay.

Charging up a battery now. I prefer to swap batteries and let one charge while using the other. I usually don't leave my Touch Pro plugged in that way.
This charger is quite convenient. It has folding power prongs, and a USB port for charging other things, like the Touch Pro directly. But, it does not charge the battery and the phone at the same time. When you plug into the USB port, it stops charging the battery in the charging slot. After you pull out from the USB port, it starts charging again.
