to be used in the input IC charger as well. With the usage of the inductor in input‚ charging time of the battery can be improved. Our inductor is also able to sustain the magnetic field from the current flowing through providing extra energy capacity and stability in current discharge. Usage for inductor in P.Charger - Based on teardown for Romoss powerbank design‚ there are 2 area that our inductors can be used. 1) Output‚ step up regulator (Low DCR-type inductor) 2) Input‚ IC charger (Typical

These components include input devices‚ output devices‚ a system unit‚ and storage devices. An input device is any hardware component that allows you to enter data and instructions into a computer. Five widely used input devices are the keyboard‚ mouse‚ microphone‚ scanner‚ and Web cam. * Keyboard- A keyboard is used mainly for typing text into your computer. *

became the main input device for computers. A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However‚ to produce some symbols requires pressing and holding several keys simultaneously or in sequence. While most keyboard keys produce letters‚ numbers or signs (characters)‚ other keys or simultaneous key presses can produce actions or computer commands. Despite the development of alternative input devices‚ such
