12V 2A Switching Power Supply (25W)

A 12V 2A switching power supply is a compact and efficient device that converts 110V or 220V AC into 12 volts DC with a maximum current output of 2 amps, providing a total power output of 24–25 watts. It is commonly used to power small electronic devices such as:

• Wi-Fi routers

• Mini amplifiers

• Portable LED lights

• Arduino or embedded systems

• Low-power CCTV cameras

Internally, it uses switching regulators to control and stabilize the voltage, ensuring that the 12V output remains constant even with fluctuations in the input or load. The high-frequency switching process allows the unit to be small, lightweight, and energy-efficient, with minimal heat generation. Most models come with built-in protections such as over-voltage, over-current, and short-circuit protection, making them safe and reliable for everyday electronics.
