When it comes to mobile phones and cars, although they have a big difference, but these two products have a certain relevance.

Today, the phone's power storage capacity is not as good as one day, when people drive a car when the phone suddenly cut off will have a significant impact, delay things. So, this car charger equipment will spread to most of the owner of the hands, but the vehicle charger quality is uneven, and many owners do not know how to use the right one, but there is a problem, it will bring great loss to you.
Note 1: before the vehicle is best not to insert the car charger, or the power supply to the phone, so as not to start the car when the unstable voltage damage charger and mobile phone.
Note two: when the car charger used for a long time to become dirty, do not use strong chemicals, cleaning agents, strong detergent to clean the charger. Wipe with a wet paper towel and dry, so as not to cause damage.
Note three: in particular, pay attention to the use of the process do not throw the car charger, landing, knocking or vibration charger.

Note four: car charger is an electronic device, the owner in the use of the process, do not put it in a humid environment for a long time, in order to avoid its internal electronic components caused by varying degrees of corrosion or oxidation. If you accidentally spilled water on the charger should be removed immediately and dry, so as not to cause damage to the circuit board.
Note five: the vehicle should be removed after the car charger mounted, if the long-term plug in the power interface, the contact part of the two may be corrupt and difficult to remove. Although 80% of the vehicles are powered by the car after the cigarette lighter to stop power supply, but also part of the car's cigarette lighter is a continuous power supply.
USB specification for current overload protection requirements shall not exceed 5A. The need for overload protection is due to the fact that when the output current is too large and exceeds its normal output value, the life of the charger will be shortened or the temperature is too high to cause damage or even burn. So in the car charger must have overload protection measures.
The input voltage of the on-board charger on the market is basically 12V - 24V, the output voltage is 5V, and the output current is about 1A~4A. But part of the "three noes" or "cottage" products are generally charging current virtual phenomenon. If you are using a mobile phone navigation is charging, not only can not provide poor quality rechargeable battery charging will continue to decline.
