If it says .5V (point five, or half a volt) then it is not much use for anything. Sorry.

Regarding the radio, some hand-cranked radios are indeed designed to do what you suggest. Have a good look for a small socket on the radio which might indicate it could be used as a phone charger. Sometimes there is a socket for an external charger to top-up the radio's batteries. Sometimes there are two sockets- top-up and power output.

Alternatively please post the model number, or Google for it.
