12v Power Brick Views

• General Goods

The laptop computers that we use run off of direct current, generally 12 volt, but our house current is nearly universally alternating current or AC. When you are working on your laptop and you have it plugged in, you are using a 12V power supply. The big rectangle that bridges the two types of power cords you use, one from the computer to the 'brick' and the cord from the 'brick to the wall outlet carry the different currents to the desired places. The 'brick' changes the AC current that comes in from the wall to DC current that keeps the batteries charged in the computer and supplies the power to run the computer.
