9V 1A DC Power Supply (for Arduino)

A 9V 1A DC power supply is a device that converts AC power from a wall outlet into 9V DC power at a maximum current of 1 amp. It is commonly used as a power source for electronic devices, such as the Arduino microcontroller. This type of power supply is also known as a "wall adapter" or "wall wart."   Use this standard 9V 1A DC Power Supply directly with your Arduino to power the Arduino and components that need more current than what the Arduino can provide. This is the perfect power supply for a project that requires power from a standard wall plug directly. Use it to charge your device's battery or leave it on full time, this module is designed for both scenarios.
