Car Charger Question with Touch Pro

[thestick00]

I had purchased a car charger from one of the members on this site and it no longer works with the Touch Pro. Oddly enough it will charge other devices like my moto s9 BT headset. My question is can I use the OEM charger from my Moto S9 BT Headset to charge the HTC Touch Pro. I checked on ebay and there are a huge number of cheap chargers that all list being able to charge BOTH items, and a host of others. I tried connecting it and sure enough it will charge. My question is is charging with the OEM car charger off the Motorola S9 BT Headset safe, and will it not damage my TP or the battery? I realize I could buy another charger, but this one seems to be of very good build quality and if I could use it with no risk on both my Bluetooth Headset and my HTC Touch Pro, that would be a wonderful way to cut back on cords. Please, anyone with info, let me know.

MOT/RIM (on the cord)
