Samsung Juke charger plug size

I just purchased one of these, a wind up cell phone charger for my Samsung Juke. Cool idea, considering that the phone only needs charging once every several days so I either lose the charger or forget to charge it until I’m just coming out the door. I even took the time to notice that one of the four or five plugs included looked very close to what I have for my Samsung Juke charger.

:smack:

Was just a bit too small… Definitely looks almost exact… But close doesn’t count.
Now I wonder… Is there an adapter I could build? I have two of the chargers… Just that I think the port for that isn’t just for power, its also for data… So I don’t know how well that would go.

Is there another adapter that I could get out there? Or even another wind up charger that would fit it with its own adapter?

Googling isn’t helping me… Just wondering what the size of that plug is.
