My cable that came with my Tour will charge and synch just fine when connected to a PC/Laptop.
I have an adapter that plugs into the car socket and then has a USB port. (5V@1000mA) When I use my USB cable that came with the phone, it doesn't charge. But when I use the cable that came with my Jawbone, it charges the phone just fine.
What gives? Can't be a current issue since it works with one cable, but not the other. Unless the charge+sync cable is wired differently than that charge only cable that came with the Jawbone.
I know my phone will charge on less than the USB spec (5v@500ma) as I have a wall charger than came with my old Samsung bluetooth that is 5V@250ma and that charges my phone just fine - albeit a bit slower.
I think BB's are tempermental when it comes to charging.
