Kindly note:
(1)Please find the spec label of your device and check the working voltage. It should be12V DC, not be AC 12V or lower/higher than 12V DC. Otherwise, your device will not work or be damaged.
(2) Check the max current your device will draw. It should be equal to or less than 1A,such as 550mA,0.65mA,0.8A,1A.Otherwise, your device won’t work well and the power supply will be damaged very soon.
(3)Check the power input port of your device. Its outer diameter should be 5.5mm; inner core diameter should be 2.1mm/2.5mm. Center Positive "+", exterior polarity should be" - ".
(4)If you have a power supply for reference, their output voltage, plug size, polarity should be the same .If our Adapter’s current is equal to or higher than original one’s, then our adapter will work with your device.
