A 12V 1A adapter is a power supply that provides a 12-volt output with a maximum current of 1 ampere (A). These adapters are commonly used to power various electronics and devices that require a 12V input.

Key Features of a 12V 1A Adapter:

1. Voltage (12V): The output voltage provided by the adapter is 12 volts. This is a common voltage level used by many devices.
2. Current (1A): The adapter can supply a maximum of 1 ampere of current. This means the total power output is 12V * 1A = 12 watts.
3. Power Rating: The adapter provides 12 watts of power, which is important to ensure that the device you are powering doesn't exceed this limit.
4. Connector Type: The connector type for these adapters can vary (e.g., barrel jack, USB, or other custom connectors), so it’s important to check that it matches your device.
5. AC Input: Most 12V 1A adapters are designed to convert AC (Alternating Current) from your wall outlet (e.g., 110V or 220V, depending on your region) to DC (Direct Current) at 12V.
