Are all DC plugs the same size?
James Bradley Are all DC plugs the same size?
Common sizes and interchangeability Generic plugs are often described by their inside diameter, such as 2.1 mm DC plugs and 2.5 mm DC (direct current) plugs. These 3.5 mm OD plugs are normally used for lower voltages and currents.
What does a DC Jack do?
A DC jack is a component used in many electronic devices that allows a steady power source to be plugged in. Therefore with most electronics, an AC adapter connected to a DC jack is necessary to supply power in a usable way.
What is polarity of DC power jack?
Usually (usually), the red one is positive and the black one is negative. The positive should go to the internal pin and the negative to the external surface. In doubt, have a look at the laptop, it should tell you the polarity of the DC power jack. Centre-positive is far more common, but by no means guaranteed.

Can I use 12V DC instead of 12V?
As long as the voltage of the “DC Appliance” is not less than the 12 Volt adapter then it will either work or won’t, all in all it’s a bad idea to experiment, actually it’s a bad idea just to even think about doing it, unless you know about what you are about to do, don’t.
