If a device doesn't have its own supply of power, it likely has to use an AC adapter get power from the AC of a building. An AC Adapter is a type of power supply — a device that provides power to another device. Such power supplies are used with cell phone chargers or the power cords for gaming systems. The large block that plugs into the wall is the power supply that converts AC power to the appropriate form for the device. Other names for this type of AC Adapter include a plug pack or a wall.
Another place one may find the power supply is in laptop charger. In order to keep the power supply from taking up space on a wall and blocking others, some AC Adapters have their power supplies in on the floor. This may-in-line configuration allows for the actual plug to be a normal size to allow more room at the wall outlet.
Having an AC Adapter to power a device allows for several advantages to the device and its manufacturer. All he needs to do is include or sell the correct adapter for the country in which the device is being sold or used. One of the drawbacks to an AC adapter is that they oftentimes can be difficult to replace. If the adapter from a laptop is misplaced, for instance, an adapter from another type of laptop generally cannot be used to replace it. To offset this difficulty, some manufacturers have developed universal AC adapters. These adapters come with a switch so a person can choose the appropriate voltage as well as interchangeable tips so he can choose the correct one for his device.
