45W MagSafe Power is a Premium Quality Adapter for MacBook with a magnetic DC connector that ensures your power cable will disconnect if it is put under extreme strain and prevents fraying or weakening of the wires over time. Furthermore, the magnetic DC helps guide the plug into the device for a quick and secure connection. The lithium polymer battery is recharged by this power supply whether the computer is turned off, on, or in sleep mode. If you decide not to use a battery, it also provides the system's power. An LED at the top of the DC connector will light up when the connection is reliable; an amber light will indicate that your portable is charging, and a green light will indicate that you are fully charged. In addition to the AC wall adapter (also included), which makes traveling even simpler and more convenient, the adapter comes with an AC cord for maximum cord length. The adapter has been particularly created for MacBook Air and is the ideal travel companion. The DC wire may be neatly looped around the device thanks to a creative design, making cable storage simple. This Adapter is Compatible only with MacBook Air featuring MagSafe power port. The MaxGreen 45W MagSafe Power Adapter comes with a 01-year warranty.
