The car charger factory tells you how to pick the car charger

1, Double mouth or mouth (but it is best not to charge too many devices at the same time)

The so-called double mouth or mouth, refers to the more than two USB interface. Because at the same time can be more than two devices to charge, for example, two mobile phones, or a mobile phone an iPad. When buying, pay attention to whether the width of the two USB interface is appropriate, whether at the same time into the two commonly used USB charging cable without crowding.

However, too much electrical load on an interface, easy to burn car insurance. In addition, the more received, leakage, the possibility of accidents will increase, so, if not necessary, do not charge too much electrical appliances at the same time Oh.

2, Pay attention to the total output, but also concerned about single-port output

In general, the car charger will give you a marked total output power, some people think that as long as the total power is enough, OK. However, once the single-port output is not enough, or will encounter some of the larger power consumption of digital products even if the plug can not charge the situation, such as iPad.

For simplicity, I will directly tell the answer, if you buy the car charger to support the total output 5V / 3.6A, single port output maximum 5V / 2.4A, then no matter what you use the phone, with an iPad at the same time charging no problem.

3, Select the output current of more than 1A products

Car charger on the market input voltage is basically 12V-24V, the output voltage of 5V, while the output current is about 1A ~ 4A. But part of the "three no" or "cottage" products are generally appear charging current virtual standard phenomenon. To battery capacity 1470mAh iPhone4S, for example, 1A current charging only about 2 hours can be filled, and poor quality product charging time will need to double.

Even worse when you use those charging current in the 500mA charger for mobile phone charging, if you are opening the phone navigation state, this time not only fully charged into the power, and sometimes the phone will go down! So when you choose the car charger must be optimistic, at least choose to charge the current 1A or more products.

4, The shell is best for forming a metal, the reason is very simple, easy to deformation of plastic, not high temperature (think about how hot summer car). One piece of metal molds are both quality and deformation is not easy to lead to leakage, but also more secure.

5, Real-time voltage monitoring

Once the voltage is found abnormal, you can immediately take measures to help extend the battery life.

6, Select the product with overload protection

USB specification requirements for current overload protection shall not exceed 5A. Car charger is the need for overload protection because when the output current is too large and more than their normal output value, the charger component life will be shortened, or due to high temperature lead to damage or even burning. So the car must have overload protection, if there is overcharge, over voltage, over temperature, undervoltage, short circuit protection is better.
