12 V 1.5 A desktop power adapter

This 12 V 1.5 A power adapter from Shenzhen Kaifa Technology is built for devices that require a steady 12-volt supply. It accepts a universal 100-240 V input at 50-60 Hz, making it suitable for worldwide mains voltages. The unit delivers up to 18 W of continuous power for compatible hardware.

The adapter terminates in a 5.5 mm outer-diameter, 2.1 mm inner-diameter barrel plug that mates with matching DC jacks on routers, small displays or embedded boards. Its 0.7 A input draw keeps mains loading low, freeing capacity on shared power strips. No additional cables or gender changers are required for a direct connection.
