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 , amperes, 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

   en.wikipedia.org/wiki/Automobile_auxiliary_power...

   For the 12 volt systems, the center contact is the positive terminal and the shell is the negative terminal. Most automobiles connect the negative terminal to the frame of the vehicle (negative ground). 12 volt auto connectors are made to comply with a standard by Underwriters Laboratories for safety. UL2089 was developed to cover the ...

4. Float voltage - Wikipedia

   en.wikipedia.org/wiki/Float_voltage

   Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]

5. AC adapter - Wikipedia

   en.wikipedia.org/wiki/AC_adapter

   [15] Electric fans, lamps, alarms, coffee warmers, battery chargers, and even toys have been designed to tap power from a USB connector. Plug-in adapters equipped with USB receptacles are widely available to convert 120 VAC or 240 VAC power or 12 VDC automotive power to 5 VDC USB power (see photo at right).

6. Charge controller - Wikipedia

   en.wikipedia.org/wiki/Charge_controller

   Charging controller of a USB power bank. A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from electric batteries to protect against electrical overload, overcharging, and may protect against overvoltage.

7. Trickle charging - Wikipedia

   en.wikipedia.org/wiki/Trickle_charging

   Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, enabling the battery to remain at its fully charged level. This state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.
