Products covered by the standard include cord assemblies of a plug that mates with the standard cigarette receptacle found in automobiles. The only way to know for certain is to check with your local dealer or the manufacturer.

The lighter is a metal or plastic cylinder containing a thin flat coil of nichrome metal strip, through which high current (≈10 amperes) passes when the device is activated, usually by pushing it into the socket as though it were a push-button. In some models, the cigarette lighter outlet is not powered when the ignition key is removed and charging is not possible. The service technician couples one or more signal leads to the vehicle's battery, alternator, or accessory receptacle (e.g.. [12], Equipment intended to be powered by the receptacle needs to account for intermittent contact, and voltages outside the nominal 12 V DC, such as maximum voltage 9–16 V continuously, or maximum voltage of 20 V lasting 1 hour, 24 V lasting 1 minute, and 40 V lasting 400 ms.[13] An example of protection component ratings tolerance is +50 to −60 V DC. → The smell of cigarette smoke clung to his clothes. Lone Star Aviation’s Power Adapter, (cigarette lighter receptacle) is a universal power accessory compatible with a multitude of consumer products. Sold & shipped by Poweradd. Standardized 12 volt DC automobile plugs are defined in the United States by UL Standard 2089 regarding vehicle battery adapters. UL2089 was developed to cover the requirements for portable adapters rated 24 V DC or less that are intended to be supplied from the battery powered electrical system of a vehicle. The De Facto 12V DC Power Socket", "Testing power from car cigarette lighter socket ? [10] When used, DC to DC converters will usually compensate for small fluctuations, but reliable power may not be available without an independent battery-powered uninterruptible power supply.
Signalez des exemples à modifier ou à retirer. Most cars nowadays are designed with a battery-negative earthing system and therefore have +12v positive power distribution. The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts during engine start due to the high temporary battery current usage. [2], In the United States, cigarette lighters started appearing as standard equipment in automobiles in 1925–1926. [14] Robust equipment must tolerate temperatures varying between −40 and +85 °C (−40 and 185 °F), plus possible high humidity and condensation of water. [4] In the reel-type lighters, the igniter unit was connected with a source of current by a cable which was wound on a spring drum so that the igniter unit and cable could be withdrawn from the socket and be used for lighting a cigar or cigarette.
