In Europe, 12 volt plugs and sockets are not specially regulated and do not require approvals for the CE mark. [citation needed] The male plug is sometimes used to feed power into a vehicle to recharge its battery because it usually has no regulatory circuitry between the outlet and the car battery. For instance, portable solar battery ...
An alternative to jumper cables is a cable used to interconnect the 12 volt power outlets (cigarette lighter outlets) of two vehicles. This method slowly recharges the battery, not by providing the current needed for cranking, as the engine cranking motor current draw will greatly exceed the fuse rating in a cigarette lighter outlet.

A power bank is a portable device consisting of a battery, a charger to interface battery with charging power source and an output interface to provide desired output voltage. [10] Power banks are made in various sizes and typically based on lithium-ion batteries. A power bank contains battery cells and a voltage converter circuitry.
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.
