The Charge 2 Go™ series was designed to act as a charger from one primary or secondary cell to a portable device powered by a single-cell lithium battery. It was designed to work optimally with mobile phones and PDA’s.

The Charge 2 Go™ charger is the first truly wireless battery charger for mobile electronics. It is ideal for use as a travel charger, thus eliminating the need to carry to bulky device charger. It is also suitable for areas where AC power is not easily available.

The Charge 2 Go™ was developed using a proprietary IC as the main up-converter / charger. This charger was designed to maximize charging current and efficiency in order to deliver maximum charge to the battery. It starts up automatically when a device drawing current is connected at the output, enabling the immediate operation of the device even if the battery is fully depleted.

Operating Procedure

Primary Battery
The Charge 2 Go™ is intended for use with one standard 1.5 V AA primary or secondary cell. It can, however, be used with any 1.5 V primary battery of any standard size. Higher quality or premium batteries are recommended, as their lower internal resistance increases performance of the circuit. In order to optimize charging, the circuit decreases the charging current when the AA cell voltage falls below 1.1 V, and stops charging altogether when it falls below 0.6 V.

The Charge 2 Go™ was intended for use with cellular telephones and other similar devices that are powered by a one-cell lithium battery of any capacity.
Since each device model has different charging characteristics, it is possible that the circuit will function differently with some models. Such situations can be rectified by slight changes to the circuit.

Comparison to Existing Chargers
The following table shows how the Charge 2 Go™ external charger’s properties compare with those of Nokia’s standard wall chargers.
