I had a an old, powered mini-usb hub that stopped working with my webcam and USB scanner. I was about to toss it when I pondered if it still would would just send power to what ever was plugged in. Sure enough, I now have a wall wart endowed charger for my first gen iPod Shuffle. Handy!
I have a small power adapter to USB for my iPhone and it charges it about 2x as fast as my puter does. How’s this one?
Good question! I loaned my Shuffle and this charger set up to my mom so I’ll have to ask her.
