The most common use of car charger six errors

Often see many owners asking about the use of car charger, in fact almost everyone ask, but the answer is every kind of, even contradictory, look so tangled, so I want to put these common problems and many people often make mistakes together, to tell you the answer right!

Error a car charge output current is not greater than the maximum rated power input
Right is the charging current "can not", for example, an output of 5v/2.1 car charger, to a maximum rated power input for the 5V/1A mobile phone charging, the charger for mobile phone input is 1A, input to the tablet computer is 2A, can in a shorter time with electricity; but if a car charger output current is 5V/0.8A to the same mobile phone charging, the input is 0.8A, not only slow, but also serious burns, long time will damage the mobile phone battery. So choose a car charger output current high enough, it is necessary to extend the life of your love. General mobile phone, including the required current is 1A (part of the 2A), tablet PC is generally 2A, then choose more than USB interface charging car to meet these standards.
Misunderstanding two cars have no need to charge the car USB interface
There are a lot of cars are equipped with USB interface, and may also more than one mouth, most people think that the car's USB interface to the phone or any other device charging no problem. In fact, this idea is wrong, because most of the car's USB interface is for audio data transmission and setting, so the current interface part of the vehicle is far from 5V/ 1A, explained the charging current "big small" reasons to you, if you use the USB interface to the mobile phone even the tablet computer is charging current, if not standard will make the equipment damage. Another Android phone or tablet computer will charge for each vehicle charging equipment identification, design are not the same. So, we may still be on the car after all not to regard it as right USB interface, built-in charging more convenient and save money, the website did a test on different models.
The output current can reach more than 0.9A in general for charging the mobile phone does not have what problem, but for the 2.1A tablet computer and 2A Android mobile phone is not enough, not to mention those only about 0.5A models. In addition, some of the Android mobile phone charging on the USB may be embarrassing, the current plunged to below 0.5A, the reason is part of the car's system to identify some of the problems of Android phones. So it is recommended that if the owner needs to charge the car charger or buy better.
Error three USB interface, the slower the charging speed
The current depends on the voltage, does not depend on how much the USB interface, because the current is already divided, and do not interfere with each other, if it will be slower than the single USB interface, who will go to buy it? Manufacturers design a number of U port, mainly in order to facilitate the owners while allowing a variety of electronic products.

But there exists some, the nominal low current car charger for high current output of the manufacturers, because the current output is larger, the material and production process of the higher requirements, unscrupulous businesses in order to really is what is done out of the cost savings, buy is really bad. But at least should have found good, we like this is not a professional testing instrument of the owners, is the only observation car charger to buy back, if at the same time to the mobile phone and tablet computer charging, and slow heating and very serious, is the current standard, the best immediately replaced.
Misunderstanding four after the car must be pulled out of the car charger unplug, otherwise the battery will lose power
This statement will see in many places, but now most of the car cigarette lighter is ACC instead of regular electricity, that is to say you can turn off the car power, this is the practice of safety. Even flameout energized models, general car charger without a load is not current output, so it is not only a little off, LED lights in the work, the loss of electricity can be neglected.
Error five car charger must be turned off after the power switch, or easy to burn
This is indeed a probability problem for many car charger, car charger which tested the anti impact ability, not all car charger are needed in flame cut off and then plug, plug car charger charged shock such as the highest can withstand DC40V, you can easily plug no problem.
Error six do not pay attention to the maximum power of the expansion port
A lot of cars on the gadget to take power with a cigarette lighter, so many people will buy two or even drag a drag three with lighter expansion port car charge, but the same product can often see some people say, some people say that the fuse, which is likely to exceed the maximum expansion of power equipment the exhibition opening. Especially the car refrigerator, car vacuum cleaner this large power must first look, what is power, look at his mouth extended car charger can not be used, usually in the packaging or instructions are marked.
