Purchase notes
Most owners may think that a simple charger all manufacturers do almost, just pick a price is not cheap on the line. But now flooded the market with all kinds of cottage car charger endless, charging current virtual standard problem, charging heating problems, LED small lights glare driving safety issues have begun to appear. So in the end what kind of car charger is good, the product price is really about the product performance,"
"Summed up the following 4 points to buy notes:
1 select the product with overload protection function
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.
2 select the output current of more than 1A products
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. To the battery capacity of iPhone4S 1470mAh, for example, 1A current charging only about 2 hours can be filled, and the quality of the charging time of the product need to double.

What's more, when you use the charging current in the 500mA charger for mobile phone charging, if you are opening the phone navigation state, this time is not only fully charged, and sometimes the phone will go down! Therefore, in the choice of car charger must be optimistic about, at least to choose more than 1A charging current products.
