How to choose the correct adapter:
1. Please find the spec label of your device and check the working voltage. It should be 6V DC, not be AC 6V or lower/higher than 6V DC.
2. Check the max current your device will draw. It should be equal to or less than 1A, such as 1A 0.75A 0.6A 0.5A.
3. Check the power input port of your device. Its outer diameter should be 4.0mm; inner core diameter should be 1.7mm. Or match other DC connector sizes we offer,Inner core polarity should be"+", 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 ac adapter current is equal to or higher than original one’s, then will work with your device.
