Mention the power adapter may be a lot of people do not know what it is, if we say that the line laptop charging accessories rectangular or common mobile phone charger touches everyone, yes, that is the power adapter is a small power supply conversion equipment, and more for portable electronic devices or electronic appliances, such as our common consoles, music players, laptops, cell phones and so need it in our power adapter.

In simple terms, the role is the role of transformer power adapter, that the apparent high voltage AC power through the power adapter rectifier, transformer, converting low voltage DC power, such as input: 100-240VAC 50-60HZ Output: 12VDC 1A which is converted into a high-voltage 100-240V low voltage 12V. In general the power adapter has a nameplate label, below the power output of the input voltage and the amount of current and other targets, special areas to pay attention to the output voltage, which is the so-called "power adapter tour", if the mains voltage as long as when 100V country, this feature is very effective, and some exotic notebook computer is only the origin of trafficking, there is no such plan, or even just a single output voltage of 100V, 220V at our mains voltage plug on will be discarded.

It can be said, the adapter function is to convert the voltage and current functions. Crown Tak Shun Technology based on customer demand, the high voltage 100-240V voltage is converted into a voltage needed 3-120VDC guests can optionally by the customer.
