Itis important to use the correct volts when choosing the adapter as a device can only run on the rated voltage. The most common are 18V, 12V, 9V, 6V, 5V and 3V. Checking the (A)mps. Acar battery at full charge is 12.65 volts. And the battery at 12.25 volts open circuit voltage is down around 25% charge which is basically dead, so if you have a 12 volt power supply that puts out only 12 volts, then it would not work. Then you mention the power supply actually puts out 13.2 volts- if that is the case then it could work Orfastest delivery Mon, Oct 2. 12W 3V 4.5V 5V 6V 7.5V 9V 12V Adjustable Voltage Universal AC/DC Adapter Power Supply for Household Electronics,Micro USB - 1A Max.
