What is wall mounted power adapter?

• Wall mounted power adapter, also called wall mounted ac adapter or plug-in ac power adapter, seems very simple.
• The wall mount power supply is a space-saving option because you only need to plug one end into the wall and the other into your device.
• You plug one end into the wall and the other end into your electronic device. Then it will convert AC to a lower DC voltage.

How to Choose the Right Power Adapter?

• You need to know the recommended charging voltage and current listed on the device you are going to power. The particular voltage and current requirements of the device are usually found written on the device itself.

1. It is important to know the correct VOLTAGE requirement.

• In the best of circumstance, if one uses a device with a lower voltage than specified, the device will not operate correctly in an obvious and immediate way. At other times the device might seem to be working correctly only to later fail under a particular circumstance.
• In other words, when you stray from the required specs, unexpected bad things may occur. Some devices can be damaged by too low a voltage for extended periods of time. If, for example, the device has a motor, it may not be able to develop enough torque to turn and just idles generating heat. It is also possible the device draws more current to compensate for the lower voltage. This higher than the intended current can cause damage to the device.
• Using higher than specified voltage also can have significant consequences since electrical components all have voltages above which they fail.

2. It is also important to know the correct CURRENT requirement.

• The load is determined by the device. That is, a device that uses 2 A of current will draw 2 A of current whether the power supply can only provide the 2A, or whether it could supply 3, 5, or any other A. The current rating of a supply is what it can deliver, not what it will always force through the load.
• As opposed to a voltage where higher than or lower voltage than needed can damage the device, the current rating of power supply must be at least what the device wants but there is no harm in it being higher.
• When replacing a previous power supply, consider that power supply’s rating to be the device’s requirements. For example, if the device does not have a visible label but the device was powered from a 12V and 1 A supply, you can replace it with a 12V and 1 or more-amp power supply.
