2. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

3. Automobile auxiliary power outlet - Wikipedia

   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. [12]

4. Automotive battery - Wikipedia

   en.wikipedia.org/wiki/Automotive_battery

   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.

5. 42-volt electrical system - Wikipedia

   en.wikipedia.org/wiki/42-volt_electrical_system

   Literature on 42-volt electrical systems often refers to systems powered with a 6-cell lead-acid battery as nominally 14 volts. Depending on operating conditions, the vehicle electrical system voltage today can vary between 6.5 and 16 V, with a varying degree of ripple superimposed on this value.

6. AC adapter - Wikipedia

   en.wikipedia.org/wiki/AC_adapter

   A battery eliminator is an adapter intended to allow a device intended for battery operation, such as a radio, to be operated from an AC outlet. [15] All radios, except crystal sets, used inconvenient and messy vacuum tube batteries until the mid- to late-1920s. Battery eliminators that plugged into light sockets became very popular. [16]

7. North American Charging System - Wikipedia

   en.wikipedia.org/wiki/North_American_Charging_System

   The North American Charging System (NACS), standardized as SAE J3400, is an electric vehicle (EV) charging connector standard maintained by SAE International. [1] Developed by Tesla, Inc., it has been used by all North American market Tesla vehicles since 2021 and was opened for use by other manufacturers in November 2022.
