Universal power adapter/converter
摘要:
A universal power adapter has an input for receiving an input voltage from a power source and an output for supplying an output voltage selected from amongst two or more preset voltages. A voltage converter circuit converts between the input voltage and the two or more preset voltages. A connector tip connectable with the output connects one of the two or more preset voltages to the output.
