Probably most of the owners will think that a simple charger all manufacturers do almost, just pick a price is not cheap on the line. But now the market is full of all kinds of shoddy car charger, charging current virtual standard problem, charging heat problems, LED small lights dazzling impact driving safety problems after another. So what kind of car charger in the end is good?
Select the car charger 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.
Car charger with real-time voltage monitoring
Once the voltage is found abnormal, you can immediately take measures to help extend the battery life.
Select the car charger with output current of 1A or more
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.
