FAQ:
Q: What is a 12V power outlet?
A: A 12-volt outlet is any electrical outlet that outputs 12 volts. Cigar lighter receptacle, the most famous example. Molex connector (also has a 5 volt rail), used for connecting hard drives and optical drives, and sometimes for powering flash memory surrogate hard drive modules. Trailer lighting connector, has multiple prongs with 12 volts.
Q: What is a 12V motor?
A: 12v Motor. 12v motors are a type of electric motor that operates based on 12 voltages, which are a unit of electrical force, of energy that they convert into mechanical energy to be utilized in the powering of various machinery or equipment.
Q: What is a 12 volt power adapter?
A: 12 Volt Adapter Power Supply. The 12 Volt Power Adapter, also known as a “Brick”, “Desk Wart” and “Floor” supply, provide a regulated 12 Volts DC output. A 12 Volt Adapter Power Supply is enclosed in a plastic protective case that comes with either an attached AC cord, or a mating socket for one of the 3 common IEC cordsets.
Q: What is 12 volt power?
A: A 12-volt electrical system operates on 12-volt current rather than the more typical 120-125 volts located in most homes and businesses. A 12-volt electrical system is common in recreational vehicles, camping trailers, cars and trucks.
