    Standardized 12 volt DC automobile plugs are defined in the United States by UL Standard 2089 regarding vehicle battery adapters. This standard covers plugs and cord sets that insert into cigarette lighter receptacles. In Europe, 12 volt plugs and sockets are not specially regulated and do not require approvals for the CE mark.

  3. DC connector - Wikipedia

    en.wikipedia.org/wiki/DC_connector

    Some common DC power connectors. A DC connector (or DC plug, for one common type) is an electrical connector that supplies direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable. The dimensions and arrangement of DC connectors can be chosen to prevent ...

    en.wikipedia.org/wiki/AC_adapter

    An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.

    Both side of the proximity circuit can optionally support 12V power-over-prox (see SAE 3068/2). SAE J3068, references SAE J3400 for DC power transfer with the appropriate adjustments for the coupler proximity circuit. Depending on the topology of the vehicle on-board charger, it may be possible to charge from a J1772 EVSE using an adapter.

    Many pieces of amateur radio equipment run on 12-volt DC automotive voltage, which is also called 13.8-volt DC. The voltage delivered by a lead–acid battery with six-cells used as an automotive battery will vary depending on various electrical loads in a vehicle. Without loads the battery will float from 11.7 to 12.8 volts, and while charging ...

  7. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...
