A 12-volt outlet is any electrical outlet that produces 12 volts and can be used to refer to: The most well-known example is the cigar lighter receptacle. The Molex connection is used to connect hard drives and optical drives, as well as to power flash memory surrogate hard drive modules in some cases. It can also be found on some scooters and motorcycles that use an electrics motor.
Cigar lighter plugs come in two varieties: a simple round plug and a three-pronged plug. The round plug is suitable for use with a simple switch or rocker light, while the three-pronged plug is required for lights that have a transformer and separate metal housing for each bulb. Some types of connectors use special shapes instead; these include the flat blade connector and the L-shaped connector. These are used mainly for computer cables.
The term "12-volt" may also be applied to other voltage levels, such as 7-35 volts or even lower. For example, some battery-powered tools operate at 9 volts, which is considered a "high voltage", but they can be plugged into a normal household outlet that provides electricity at 120 volts. The phrase "12-volt equipment" is generally used to describe industrial or commercial machinery or devices that require maintenance or repairs performed by a qualified technician using appropriate safety precautions. Such equipment often uses specialized connectors or ports for input and output, such as serial ports for communication with remote systems.
The 12V socket, commonly known as a car cigarette lighter or a 12V auxiliary power outlet, is the principal means for powering portable gadgets in automobiles, trucks, recreational vehicles, boats, and a few other places. It can also be used to start some older cars with electric windows or clocks. A battery charger can be plugged into this outlet to keep batteries charged while driving.
In addition to cars, most modern light trucks and minivans are equipped with a 12V DC outlet for connecting small appliances such as cell phones, cameras, MP3 players, etc. This type of outlet differs from a house wall outlet in that it requires a special adapter plug to connect it to a vehicle's electrical system. Also, many of these vehicles' outlets will only handle a maximum current of 2.1A (20W), whereas a household outlet can carry up to 15A (150W).
Some airplanes and some large commercial vehicles have separate 12V DC power outlets for use by pilots and passengers. These outlets tend to be much more powerful than those found in cars; they can deliver up to 100W each.
Finally, some industrial machinery and equipment use 12V DC as an external power source. This type of outlet is usually heavy-duty and capable of delivering high currents.
A 120-volt outlet with built-in safety covers. The 120-volt power outlet is the most common electrical outlet found in North American houses. These outlets have been in use since the early 1950s in their current shape. They are made by several manufacturers including Eaton, GE, Siemens, and Tripplite.
In addition to supplying electricity, these outlets are also designed to protect people from electric shock. If someone were to touch one of the pins inside the outlet or try to plug a metal object into it, the circuit would be broken before any damage could be done.
These outlets need to be hardwired to a house's wiring system. It is not possible to wire them up in a modular fashion with multiple circuits running through each outlet. Doing so would risk either overloading or underloading certain parts of the network.
The presence of a 120-volt grounded outlet does not guarantee that a house is wired for electricity. In fact, many old houses were built without these outlets because they were too expensive at the time. However, this type of outlet is necessary if you want to be sure that you won't get hurt by an electrical hazard such as an overloaded circuit or short circuit.
You should check all the house wires for damage every time you do major work on your house.
