Why do people need to invent car charger ?

What is the design intention of the car cigarette lighter? The answer is simple, providing convenience for smoking. But now this function is often weakened (now smoking so hard), replaced by charging function.

The necessity of car charger for cigarette lighter

Now people are suffering from battery anxiety. Whether it's a cell phone or a car, as long as the electricity is less than a critical point (varies from person to person), it's enough to get you on pins and needles.

Therefore, the reasons for the need for car charging can be attributed to the basic human needs (from Maslow's point of view, charging in the minds of people already in the physical needs, is more basic needs).

The concept of using a cigarette lighter to recharge your cell phone is not new. We can see such products everywhere. A treasure on the product price ranging from dozens to hundreds, sales are good.

But once it's connected to electricity, safety is a top priority. Cigarette lighter output voltage is generally 12V, while electronic equipment, such as mobile phones, tablets and other input voltage is 5V. The car is charged with a transitional role in the process of conversion.

Therefore, accurate voltage control (to ensure device safety) is a prerequisite for charging a qualified cigarette lighter, which requires a very precise voltage control circuit design in the hardware.

Secondly, for the protection of vehicle battery is also necessary (flameout state, long time power supply automatically power-off), because the vehicle battery dry will affect the vehicle ignition.

Take the electric car charger from the cigarette lighter car 12V voltage 5V conversion process, through voltage regulator, rectifier, overload protection and so on a number of steps, if use is inferior to that of the original material and is prone to short-circuit, even in the case of spontaneous combustion. A car is broken, not tight, because if the car destroyed the phone, and even destroyed the car, it is really not worthwhile. Although the car charge is not what high-tech, but there are still true and false points.

Don't look at the car charger is a small object, when we buy or pay attention to buy equipment for voltage and current size, for example, portable handheld terminal product standard input voltage is 5V/700MA, and iPhone is 5V/1A. The output voltage on different cars is different. For example, the output voltage of the car is 12V, and the truck is 24V. Therefore, the universal car charger is suitable for the 12V sedan, while the on-board inverter type is suitable for truck use.
