Dual Charger anyone??

Hi all, I am wondering if sdome company has thought of this already. i am looking for a dual charger for my storm where the one end has the micro usb and the other end having both a usb connector and the wall outlet plug. I like to charge my storm on my PC exclusively. My cradle is on my desk and it's all good. The problem comes when I turn off my PC at night and I forget to remove the BB from the cradle. In the morning my battery is dead, deader than dead.... so I'm looking to have my cake and eat it too. I would like to have one spot to charge my storm.... and backup and get data as needed... by my PC but I would like it to xcharge with my PC off... any ideas? lol.

I really think that the only way to do what you want with the tools as hand today is to jumper your mobo (if possible) to allow USB power even when the machine is off. Most modern machine still deliver 5v power as long as they are connected to the wall. I am actually shocked that the cradle only has the one plug. I will keep my eyes open...
