Inverter charger can convert DC12V / 24 v dc to AC110/220 v or higher ac, can products such as notebook computers, mobile phones, navigators, use more extensive.
It is obvious that in most cases, we only need to give a phone, tablet PC, digital products, such as charging, so gm car charger can meet the demand. And the car charger is safer and more secure than the 220V output.
Is it necessary to have a car charger?
Owners will also find that the car comes with a USB port and can charge the phone. But most of the USB ports in the car are designed to transmit data, the current is only 500mA, and the charging efficiency is very low. If you use your phone to navigate, it will not even be able to charge enough for navigation. Take our phones and tablets for example, the phone is commonly charged with a size of 5V / 1A and the flat charger is 5V / 2A. So for faster charging efficiency, a USB car charger for 1A or larger output current is the best option!
The car charger design are all in the position of the cigarette lighter, many manufacturers introduced a multi-function car charger: USB interface, even bring the function of cigarette lighter car charger.

The fuses of the typical cigarette holder interface are above 10A, which is more than 20A load capacity; The power supply voltage of the vehicle is 12V / 24V, so the load capacity of the cigarette lighter is more than 120W, and the charging of the 5V output voltage is not to worry about.
Even some brands provide a multi-port car charger for easy user. The three-port USB car, like the green link, has three full loads of current at 5.8 A, 5 * 5.8 = 29w, and well below 120w.
Brand manufacturers in the design of car charger, generally on the car charger set overload protection, short circuit protection, over current protection, over temperature protection, to ensure that users in the use of security in the process of charging.
