AC adapters
An AC adapter, also known as an AC/DC adapter, AC converter, or charger, is an external power supply designed for devices that either operate on batteries or lack an alternative power source. These adapters serve the purpose of reducing the size of devices like laptop computers by eliminating the need for a standard-sized power supply. An AC adapter typically consists of two main components:
- Central Unit: This part of the adapter connects to an AC (alternating current) outlet to draw power. It then performs the crucial function of converting this AC power into DC (direct current), which is suitable for powering the computer or device.
- Cord: The second part of the adapter includes a cord that plugs into the device, such as a laptop, allowing it to receive the converted DC power.
In essence, the AC adapter ensures that devices receive the appropriate power they need to function, making them more portable and versatile.
What is an AC adapter used for?
An AC adapter, also referred to as a power adapter or charger, is a device utilized to convert alternating current (AC) from a wall outlet into direct current (DC). This converted DC power is then utilized by electronic devices like computers, laptops, and smartphones.
