Input: 100V-240V 50/60Hz; output: 12V DC, 1A max; Works with device that draws less than 1A, such as 100ma 300ma 450ma 500ma 600ma 650ma 700ma 800ma 900ma 1000ma.
DC plug connector external diameter is 5.5mm, internal diameter is 2.1~2.5mm. Comes with a female DC barrel connector. You can easily screw wires on it without soldering.
Safety protection: automatically overload cut-off, over voltage cut-off, over temperature cut-off, short-circuit cut-off.
Sufficient 12W output power and stable 12V output voltage will protect your electronic devices from destruction.
It is perfect for 12V devices less than 12W, such as LED light strip, CCTV camera security system, Bluetooth speaker, keyboard, TV boxes, webcam router ,etc.
