Yes, the Kensington charger I linked to above supports this, with the "M15" tip, which you have to order separately. One caveat: Though it charges my Motorola RAZR phone, it turns the phone on and leaves the backlight on the whole time while charging. It also prevents the phone from ringing while charging. Kensington is aware of the problem and working on a better tip. Allegedly the tip works fine with other mini-USB devices such as the blackberry.
