FAQ:

Q: Can I use a 12V?

A: Use a 12 volt system when you intend to run appliances directly from batteries. This is a safer voltage for DC circuits as opposed to any higher operating voltages.

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.

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 a 12V DC motor?

A: While smaller DC motors are commonly used in the making of appliances, tools, toys, and automobile mechanisms, such as electric car seats, larger DC motors are used in hoists, elevators, and electric vehicles.
