High-efficiency all-electric refrigerant compressors for air conditioning are starting to be used, especially in hybrid or all-electric vehicles. The cigarette lighter receptacle serves as a de facto standard for use of portable 12 volt equipment in or near an automobile, it is sometimes used with car charger to power devices with batteries.
Yuasa, a producer of 12-volt car batteries, says: “Cold temperatures directly affect the performance of car batteries. In fact, at zero degrees celsius a battery will lose about 30 per cent of ...
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.

A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle.. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
Conventional battery chargers use a one-, two-, or three-stage process to recharge the battery, with a switched-mode power supply including more stages in order to fill the battery more rapidly and completely. Common to almost all chargers, including non-switched models, is the middle stage, normally known as "absorption".
The device provides 100-volt outlets, converting the i-MiEV's direct current (DC) battery power into 100 volts alternating current (AC) to power up to 1,500 watts of small electrical equipment. Mitsubishi estimates that the i-MiEV total battery capacity is enough to provide power for between 5 and 6 hours, equivalent to one day of power ...
