The FreeCharge 12V Personal energy Source is a lightweight, durable and efficient power source 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 12V consists of a generic base unit and interfaces to the handset through a cigarette lighter socket (phone to lighter socket cable not supplied).

FreeCharge 12V 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.

Typical Performance:
360 turns (approx. 3 min wind) = 9 - 11 min talk time
Talk time: 60 second wind = 2 - 4 min talk time

For mobile phone applications talk time performance from the FreeCharge 12V is influenced by several factors. These include phone make and model, signal strength, battery condition, duration of winding effort and the charging characteristics of the cigarette charger used.

Most mobile phones have low voltage cut-out circuitry in order to protect the battery and retain stored memory data when the battery is flat. In order that this circuitry does not impact on repeatable talk time performance it is recommended that a minimum of 3 minutes winding be applied.
