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 10A,such as 2A, 5A,8A,10A. 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 2.5mm or 2.1mm. 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 PS’s current is equal to or higher than original one’s, then our PS will work with your device.
