Hi, As for the crank, I have no idea, never even tried to turn it, the solar panel on the other hand worked, but I forgot the radio on the balcony for 4 days and when I came back the radio was charged. Maybe it's a matter of time. In any case, for an emergency situation I wouldn't rely on this radio: from the quality of the construction to that of the components, it's not worth more than 20-30 francs to be generous.

That's taken care of. It was there after all. Just a little small.

I don't know if stereo works because it says mono. But Bluetooth works without problems.
