There are generally several items on the label of the power adapter (hereinafter referred to as adapter) that need attention.
First, it is the model of the adapter. For example, the model of this adapter is SOY-1200100. It tells us a few pieces of information, including its manufacturer, wattage, etc. The beginning of SOY is generally ##Company code, 1200100 means this Adapter is 12W, 0500200 is 10W;
Second, it is the INPUT of the adapter, which is generally 100-240V~50-60Hz in China, which means that this adapter can work normally under the voltage of 100V-240V;
Third, it is the OUTPUT of the adapter. Two numbers can quickly calculate the wattage of the adapter. For example, for this adapter, voltage 12V*current 1A=12W (power), indicating that the power supply is a 12W adapter.
The power adapter of most notebook computers can be suitable for 100～240V alternating current (50/60Hz). Basically, most notebook computers have an external power supply, and use a power cord to connect to the mainframe, which can reduce the size and weight of the mainframe. Only a few models have the power supply built in the mainframe.
