USB to 12V Adapter Function Converts 5V USB power to a 12V DC output through a 12V female socket, enabling devices such as DVRs to be powered from a USB source. Stable performance Uses larger shielding inductance and Schottky diodes to provide a stable and reliable power supply for connected devices. Durable construction Thick copper wire core minimizes resistance and enhances durability for long term use. Specifications Input: 5V, 1A; Output: 12V, 1A. Designed to meet common power needs efficiently. Compatibility and practicality Suitable for devices that require 12V up to 1A, powered from standard USB chargers or power banks. Use scenarios 1) Power a DVR or security camera from a USB power bank or USB wall adapter. 2) Provide 12V power to small displays or other 12V devices that accept a USBpowered source. 3) Temporary 12V power for prototyping or experiments when only USB power is available.
