Power supply
For an electronic device like the micro spy camera and many others, power is a device or system that provides electrical energy through an output charge or a charging group. Power includes any type of energy-to-energy conversion, although the term power supply often refers to a power supply.
Power is evaluated based on the power it can provide, the time it can operate without the need for recharging, the stability of its voltage and the type of power it provides. There are several types of power, such as the electric battery, the fuel cell or any other form of energy storage such as the battery, solar energy and the electric generator. In fact, small devices such as the spy camera pen where camera glasses are powered by a lithium battery. The battery life provided by such a power supply depends on the capacity of the battery. In general, the latter offers a few hours of autonomy.
On the other hand, there is also a form of power specific to the PC type computer. The power supply is plugged into a power outlet and converts the electrical voltage into continuous voltage to power the various components of the computer.
