ANSWERS TO YOUR QUESTIONS
REGARDING CHARGING
How much operating time does hand cranking provide? Crank-
ing 120 times per minute, for 1 minute, plays the radio for about 4
minutes at low volume. Since volume is relative this may be higher or
lower depending on how loud the volume is.
How long does it take to fully charge the battery by hand
cranking? It is not practical to charge the battery via hand cranking.
Since the battery capacity is 600mAh (milliamp hours). Fully charging
it by cranking would take 3 hours at 120 turns per minute.
How do you switch from hand crank direct power to just
charging the battery? When in the OFF position, cranking or solar
cell is charging the cell phone or MP3; when the switch is at the other
3 positions, both the solar cell and cranking can charge the battery.
Can the solar cell power the radio on its own, or is it just
used to charge the battery? Yes, the solar cell can power the radio
on its own, and also charge the battery.
How long does it take the solar cell to charge the battery? It
will take 12-15 hours for the solar cell to charge the battery.
A fully charged battery will last about 6 hours at low volume when
receiving radio programs and about 5 hours at low volume when
receiving aircraft band.
