A DC power supply 12v is an electronic circuit that turns an ac voltage to dc voltage. Power Adapter basically consists of the following elements: transformer, rectifier, filter, and regulator circuits.
A power supply is an electrical device to supply electric power to an electrical load. DC power supply 12v primary power supply can convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes called electric power converters. Some power supplies are individual standalone pieces of equipment, while others are formed into the load appliances that they power
Power supplies are categorized in numerous ways that include functional features. For example, a regulated power supply can maintain continuous output voltage or current despite differences in load current or input voltage. Conversely, the output of an unregulated power supply can vary significantly when its input voltage or load current varies.

Firstly, the input should be observed on the label of the power adapter, mostly the 100-240v one that has wide use. In addition, the type of input voltage changes from country to country. The plug-in also varies based on the country.
The second aspect is the output voltage and current. You may wonder if two led adapters both have the same nominal voltage and different output currents, can you use them on the same laptop? The basic principle is that a Power supply adapter that has a large nominal current can take place of a power supply with a small nominal current. The current depends on the load under the same voltage.
At last, a suitable power adapter manufacturer should protect the products from short circuits, overload over temperature. The products should have safety certification. A power adapter manufacturer can generate a power supply adapter with safety certification to protect the safety of the person in order to prevent electric shock, fire, and other dangers.
