This new system accepts various national power plugs and most laptop chargers will function properly at 120 V 60 Hz AC even if sold in 230 V 50 Hz AC markets. Apple offered an EmPower MagSafe power adapter for their MacBook , MacBook Pro , and MacBook Air lines of notebooks, and also included a cigarette lighter socket adapter.
An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
No load power consumption is the electric power consumed by a battery charger when it is plugged into a wall socket but without the mobile phone or other battery device being connected. Contrary to standby power , which is a low power mode of devices such as TVs to maintain system functions such as responding to remote control , true no-load ...
IEC 60417-5008, [7] the power-off symbol (circle) on a button or toggle, indicates that using the control will disconnect power to the device. (0 or means off.) IEC 60417-5009, [8] the standby symbol (line partially within a broken circle), indicates a sleep mode or low power state. The switch does not fully disconnect the device from its power ...
A simple charger typically does not alter its output based on charging time or the charge on the battery. This simplicity means that a simple charger is inexpensive, but there are tradeoffs. Typically, a carefully designed simple charger takes longer to charge a battery because it is set to use a lower (i.e., safer) charging rate.

(No swapping occurs if the accessory identification chip is connected to the ID0 pin.) Lightning is a proprietary computer bus and power connector, created and designed by Apple Inc. It was introduced on September 12, 2012, in conjunction with the iPhone 5 , to replace its predecessor, the 30-pin dock connector .
The adapter typically supplies power to the device through a thin electrical cord which terminates in a coaxial power connector often referred to as a "barrel plug" (so-named because of its cylindrical shape). The polarity of the adapter cord and plug must match the polarity of the device, meaning that the positive contact of the plug must mate ...
