Features: USB C input port: This USB TYPE C to female cable with highly compatible USB C input port, built-in voltage display, and real-time monitoring of output voltage. High conversion efficiency: High conversion efficiency. The larger the input current, the larger the output current, up to 12V-1.5A, ensuring efficient power supply for your devices. Wide application: It is very suitable for car devices such as driving recorders, electronic speed detectors, the 12V car socket not exceed 18W. Small and portable: The converter cable is available in 30cm and 1m lengths, making it easy to carry and use, and a reliable supplement to automotive parts. Output up to 18W: The output power can reach 18W (12V/1.5A), and the output power depends on the input power. If the input power is 5V2A (10W), the converter can boost to about 90% of the input, up to 9W. As the input current increases, the output also increases, reaching up to 18W.
