With the rapid growth of the cellular phone industry, there has been an exponential growth in cellular accessories that are available for the automobile. These cellular accessories can include chargers for auxiliary outlets, phone holders and holsters, and a wide range of Bluetooth devices.
Most mobile phone chargers are not really chargers, only power adapters that provide a power source for the charging circuitry which is almost always contained within the mobile phone. The battery in a car has a higher voltage power source, 12 volts, while a phone battery has a voltage of 3 to 4 volts. This means that the electrochemical energy is flowing from a higher energy state to a lower energy state. Cell phone chargers have their own circuitry that “steps down” the car battery voltage from 12V to the appropriate voltage required by the specific cell phone battery being charged. This is the reason cell phone chargers are rarely universal.
Many phone holders offer a variety of mount locations for each vehicle and a variety of holder styles for each device such as standard holders or passive holders, charging holders or active holders with car charger or cigarette lighter adapter, charging holders or active holders for fixed installation or hard wiring, Holders with pass-through connectors, skin case holders adjustable to accommodate the width of the device etc. Phone holders provide safer driving by allowing you to keep your device securely on a vehicle dashboard within easy reach from the driver seat.
A Bluetooth profile is a specification regarding an aspect of Bluetooth-based wireless communication between devices. In order to use Bluetooth technology, a device must be compatible with the subset of Bluetooth profiles necessary to use the desired services. This is commonly used to allow hands-free kits to communicate with mobile phones in the car.
