... sorry but a simple bridge alone doesn't make a 5Vdc stabilized output voltage !!!
I am not an expert on this but surely you dont need a stabilsed 5v output to charge a usb device. To get current to flow requires a potential difference so the charging voltage will be higher than the 5v usb spec otherwise charging would not occur.
