- Unplug the AC adapter from the wall outlet.
- Connect another device on the wall outlet to verify if the wall outlet is working correctly.
- Connect the AC adapter to a known-good wall outlet.
- Plug the AC adapter directly into the wall outlet.
What is an AC adapter used for?
An AC adapter is an external power supply that converts alternating current (AC) from a wall outlet to a direct current (DC) needed by an electronic device. Therefore, it is an AC/DC converter. When it supplies power to a battery-powered device, it is also accurate to describe it as a charger.
How does an AC to DC power supply work?
The AC power moves into a transformer to change the voltage. After the power supply attains the correct voltage, the electricity travels to the rectifier where it converts back to DC power. As with AC-DC power supplies, DC-DC models may require regulators to smooth out the signal.
What is AC to AC power supply?
Type AC Power

Definition The standard type of electricity supplied from the electrical grid to homes and businesses.
Electric current Waveform
Advantage An excellent way to deliver electricity over long distances and is suitable for distribution via a mains grid system.
Can you use AC to power DC?
Direct current can come from multiple sources, including batteries, solar cells, fuel cells, and some modified alternators. DC power can also be "made" from AC power by using a rectifier that converts AC to DC. ... Not all electrical devices use DC power, though.19 mar 2020
Can you use an AC plug on a DC device?
In many instances, yes. The central function of AC adapters is the conversion of mains current from AC to DC for electronic devices with a rechargeable battery.
How do I know if I have AC DC adapter?
One way to determine if you have an AC-DC power supply or a DC-DC model is to look at the device itself. Often, the input and output information will appear somewhere on the surface. If the input is AC, you have an AC-DC power supply, and you have a DC-DC model if the input and output both are DC.
