How to determine whether this adapter is suitable for your device:
1. Please find the spec label of your device and check the working voltage. It should be 12V 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 2A, such as 0.5A,1A, 2A. 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. Inner core polarity should be"+", exterior polarity should be" - ".Please confirm whether the listed DC interface size includes the power input interface size of your device.
4. If you have a power supply for reference, their output voltage, plug size, polarity should be the same .If our ac adapter current is equal to or higher than original one’s, then it will work with your device.
