Background and Identification
1-Amp USB (Universal Serial Bus) car chargers are designed to charge electronic devices while in the car by plugging it into an automobile auxiliary power outlet. An automobile auxiliary power outlet (also called car outlet, automotive power socket, automobile outlet, vehicular outlet, and formerly known as a cigarette lighter receptacle or cigar lighter socket) is a de facto standard DC connector to supply electrical power for portable accessories directly from the vehicle’s electrical system. Car chargers plug into cigarette lighters in cards and act as a charging adapter. Generic 1A USB car chargers are generally made from cheap plastic and thin stamped metal. Most car chargers of this type feature slim profiles that protrude less than one inch from the cigarette lighter socket when installed. Car chargers will charge most smartphones, MP3 players, and some portable gaming devices. Many 1-Amp USB car chargers also include power-on indicator lights that tell the user when the device is charging.
Generally, 1-Amp USB car chargers have a DC output voltage of five Volts and an input voltage of 12 Volts (direct current). These chargers include USB ports that allow the use of a USB cable to connect a device to the car’s electrical power supply.
In newer cars, the cigarette lighter outlet is equipped with a plastic cover without the lighter heating element. These outlets usually have a plastic cap tethered to them and are usually labeled as being only for DC power. These outlets in newer cards are not intended to withstand the heat produced by an electrical cigarette lighter.
