The SY001 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.
SY001 is simple to use, just follow these steps:
1. Load a single AA battery into the SY001 and a small, red light will begin flashing.
2. Connect your phone-specific connector to the flashing unit.
3. Connect your phone to the connector.
4. Your phone indicates that it is charging.
