Q: What is a 12V DC power supply?

A: A 12V socket is a cylindrical receptacle that provides direct current (DC) at 12 volts to a device plugged into it. The most commonly known 12V sockets are found in automobiles, and were originally provided as part of a system that heated a metal coil in a heat-proof holder to light cigars and cigarettes.

Q: What is switching adapter power supply?

A: A switched-mode power supply (SMPS) is an electronic circuit that converts power using switching devices that are turned on and off at high frequencies, and storage components such as inductors or capacitors to supply power when the switching device is in its non-conduction state.

Q: What is a 12V battery used for?

A: 12-volt batteries are commonly used as car batteries. Most car batteries are lead acid 12-volt batteries. Alternators charge a vehicle’s battery and supply its electrical system with power. Some boats use a 12-volt battery. A portable 12 volt battery is usually sealed in a waterproof case.
