What should you note when using a car charger and how to pick up a quality car charger

First of all,we have to figure out what the difference between the car charger and common charger is , the fundamental difference between them is basically the plug – car charger  plug is specifically linked with cigarette lighter in the car (usually in the cab and luggage box)   The other end of the car charger is specifically designed with the USB port  the cell phone or other digital devices can be connected to.Which data lines connected to the car charger  depends on which digital device you use.
The car charger does not work unless the LED indicator lights is lighting up.
Note that, do not charge the phone until the car engine is started! Otherwise, when the car is ignited, the reduction in voltage  of car battery will affect the charging effect, or even damage the car charger.
Furthermore,do not place the charger to moisture or high temperature environments, the use of a suitable temperature is 0-45 ℃;

There will be some heat during use,be sure not exceed 60 ℃ in normal room temperature;
Since various types of rechargeable product are different, the charging time is inconsistent, it has nothing to do with the charging performance of car charger;
Keep away from children;

Avoid lightning; Promptly pull the plug when the car charger is fully charged, careful not to dirty the USB interface, remove the installed car charger and put it away when not in use.
So, for safety reasons, be sure to buy the regular brand, buy genuine, inferior products prone to security risks.

There is substantially no adverse impact for brand original car charger.Why?Car charger is one of auto accessories charging digital products at any time in order to facilitate vehicle owners to use. Some high-end car charger typically includes two USB ports, which can simultaneously charge two digital products. These products generally feature overload protection, short circuit protection, high voltage input protection, high temperature protection to ensure safe use to realize car charger direct charging, USB charging and triple multi-use while being charged in the car.

The voltage outputted by car charger is typically 5V transferred from 12v-24v and limiting current is 500mAh, for those knock offs without protection function, the circuit has many flaws, if the buck and current limiting circuit fails, it will lead to 12-volt direct accessing to the phone, resulting the phone  burned. It is recommended to use the the original charger after car inverter volt rising to 220.

Conventional car charger powered by car battery (car 12V, trucks 24V) is widely used by a variety of portable, rechargeable handheld devices equipped with lithium battery, such as: mobile phone, PDA, GPS, etc; car charger do not only consider the actual demand (constant voltage CV, constant current CC, OVP OVP) on lithium batteries, but take into account the harsh environment of automotive batteries (transient voltage spikes, the system switching noise interference, EMI, etc.); therefore Power Management IC of car charger program must be switching power supply chip featuring with high pressure, high efficiency, high reliability, low frequency (in favor of EMI design).
