The FreeCharge 12V Personal Energy Source is a lightweight,
durable and efficient power supply for mobile phones and
other electronic devices, powered by winding a hand crank,
it is independent of conventional power supplies and batteries,
enabling the user to make and receive calls at any time,
even with a flat phone battery.
The FreeCharge consists of a generic base unit and interfaces
to the handset through a cigarette lighter socket. The
charging protocols are matched to individual handsets
by plugging a cigarette lighter charger specific to each
phone (not supplied). With a comfortable and sustainable
winding effort, the FreeCharge will adapt its output to
match the requirements of the recipient device via the
cigarette charger.
Regulated to deliver the same voltage output as an automobile
while cranking, the FreeCharge 12V provides a portable
power supply for a wide range of applications using up
to 12 volts.
FreeCharge is equipped with an LED charge level indicator
that illuminates when the crank handle is turned at an
optimum speed, however charge and talk times will vary
between phones and cigarette chargers.
Internall mechanical components are specified to industrial
standards for repeated use and long life.
