What is usb to 12v?

USB to 12V is an electronic adapter that can convert the power output from a USB port (usually 5V) to 12V DC. It is commonly used to power devices that require 12V DC, such as car DVD players, cameras, and routers.

USB to 12V adapters are available in different sizes and shapes, and with varying voltage outputs. Some adapters have fixed voltage outputs, while others can be adjusted to different voltage levels. The power output capability of USB to 12V adapters also varies, with some models capable of delivering up to 5 amps or more of power.

When selecting a USB to 12V adapter, it is important to ensure that the voltage and amperage output are compatible with the device to be powered. Some adapters may also come with additional features, such as overcurrent protection, short circuit protection, and overvoltage protection, to safeguard the device against damage.
