I've had this hand
cranked radio since I got it at a post Y2K clearance sale.
It comes in handy for power
failures like on Monday. Just crank it 50 times and you've got
about 20 minutes of radio.
The solar cell needs direct
sun and does not charge a battery.
A bonus feature is a DC out
jack that allows something small and external to run off the powerful
spring winder.
