A 5V 4Amp power supply is an electronic device that provides a constant 5 volts of DC (direct current) power with a current capacity of up to 4 amps. It is commonly used to power electronic devices that require 5V input voltage and higher current capacity, such as LED strips, CCTV cameras, and microcontrollers. The power supply can convert AC (alternating current) voltage from a wall outlet into a constant 5 volts of DC power to keep the device running.
