Why do you need a car charger, the old driver told you

According to the survey, in 2015 China became the world's largest auto market: 2015 annual Chinese market car sales reached 24 million 590 thousand! More and more consumer electronics products such as mobile phones, tablets, digital cameras are also integrated into everyday life. These electronic products have become an indispensable vehicle driver in the car. However, the use of electronic products in the process will inevitably be lack of electricity, thus affecting the use, so the owner will be equipped with car charger for car.

Car charger classification
According to the different types of car chargers on the market can be divided into: general car charger and inverter charger. General car charger output is low (5V/9V), the only mobile phone, tablet, digital products charge; inverter charger can convert DC12V/24V DC AC110/220V or higher AC, notebook computer, mobile phone, you can charge the navigator and other products, the use of a wide range.
Obviously, most of the time, we just need to give the phone, tablet PCs, digital products, such as charging, so the universal car charger can meet the demand. And compared to the 220V inverter output, universal car charger is safer, more secure.
Do you have a car charger?
Owners will also find that the car comes with USB interface, but also to charge the phone. But most of the USB interface is designed to transmit data, the current is only 500mA, charging efficiency is very low. If the use of mobile navigation, charging is not enough or even navigation consumption. In our mobile phones, tablet, for example, the phone is commonly used to charge its specifications for 5V/1A, flat charger specifications for 5V/2A. So to achieve faster charging efficiency, 1A or greater output current USB car charger is the best choice!
The car charger design are lighter in position, many manufacturers launched a car charger function: USB interface, even car charger comes with lighter function. This multi-function car charger will not affect the function of the car itself, is also extended to more features, let charge, cigarette lighter, data transmission does not affect mutually, greatly facilitate the use of the vehicle.
Is the car charger safe?
The current car charger connected in the cigarette lighter position, one can load capacity for lighter interface in doubt, but don't worry. General car cigarette lighter fuse interface in 10A above, some even reach the load capacity of more than 20A; and the vehicle power supply voltage is 12V/24V, so the load ability of the cigarette lighter interface basically in more than 120W, with the output voltage of the 5V car charger, is no need to worry about.
Even some brand for the convenience of users and the launch of several car charger, cigar lighter is fully capable. This year like a horse car charger 2 USB car charger, the 2 full load current up to 5.8A, 5*5.8=29w, is far less than 120W.

Buy car charger should pay attention to the following points
Although the car charger is a small thing, but it is almost essential car supplies, the technical content of the product itself is not high, numerous manufacturers. In addition to purchase the brand and price measure for having heard it many times the quality should have more choice.
1, to understand the car charger automatic protection function
Car charger whether overvoltage, overcurrent, overheating, short circuit protection and other functions, the shell is the best ABS environmental friendly flame retardant materials, can prevent the external combustion and beautiful, do not touch the handprint.
2, pay attention to the voltage and current size
When you buy a car charger, pay attention to the voltage and current matching equipment, such as iPhone is 5V/1A, tablet PCs, mobile power is 5v/2A. Dual USB car charger for mobile phone and tablet computer at the same time if the charge, the total current car charger at least 3A or above, otherwise the charging speed will not only greatly decreased, excessive heat and even bad filling equipment.
3, choose a reliable brand
Reliable quality of the brand can be guaranteed, the use is also assured that this truth is not to say more. Although the price is generally higher than the poor quality car charger, but if the cheap, the quality of the problem, it is certainly no complaints.
