Type of adapter
A power adapter is a device designed to convert electrical current from one form to another suitable for powering certain electronic equipment.
The main characteristics of power adapters are:
1.Input Voltage – The range of voltage applied to the adapter input (e.g., 100-240 VAC, 50/60 Hz).
2.Output Voltage – The voltage output by the adapter (e.g., 5 V, 12 V, 19 V, etc.).
3.Output Current – The maximum current the adapter can deliver (e.g., 1A, 2A, 3A, etc.).
4.Power (W) – measured in watts (W) and calculated as the product of the output voltage and the output current (e.g., 12V × 2A = 24W).
5.Connector type – can be male (DC connectors of different diameters), USB (Type-A, Type-C), magnetic (e.g., MagSafe), and others.
6.Type of construction – AC adapter (built into the socket), power supply with cable, switching or transformer power supply.
7.Additional features – protection against overheating, short circuits, power surges, support for fast charging (Quick Charge, Power Delivery, etc.).
Power adapters are used to charge mobile devices, laptops, cameras, LED strips, household appliances and other equipment.
