Which several cell phone chargers are divided into


Mobile phone chargers can be roughly divided into travel charger, seat charger, USB charger and maintenance charger.
 
As we know that the general users are mainly in contact with the previous two kinds. The travel charger sold most. Travel charger has a variety of forms, and the common cheap ones are duck-micro travel charger, ordinary desktop card board charger and top grade desktop charger with LCD.
 
Because the mobile phone users are mostly non-professional users, most of the chargers are with full auto stop feature basic, and most of the travel chargers are fast charging, with charging time of 1-3 hours. 
 
Many charger producers on the market advertised himself as a microcomputer control, including some very cheap prices duck type micro travel charger. But in fact, strictly from the charging circuit analysis, very small part of the chargers are recognized as the true meaning of a microcomputer control (SCM control) .
 
Some manufacturers use the charging line Manifold on the self-proclaimed "microcomputer control, in fact, many of the low-cost design chosen manifolds are inexpensive op amp Manifold. While some dedicated charging control Manifolds with higher prices are generally used in the more upscale brand name chargers.


So we can not believe in the so-called micro-computer control, especially the cheap products. Many products are similar in appearance, but the internal circuit is quite different as well as its performance.

How to Choose High Quality Cell Phone Chargers


The products which are made with an effort will have high quality. It is no doubt. In manufacturing, with the same machinery equipment, the same management method and the same raw materials, we will get different products. Why is this? This is mainly because different people are on work obviously and they make products with different effort. So, whether you ever get on the products, it reflects in several aspects, one is the perfect appearance, second, it is to conform to the safe material, and the last is stable performance. Therefore we recommend that users should judge your mobile phone charger from these three aspects.

Here, we also need to mention the mobile phone parameter which is the mobile phone tag parameters: such as output 4.4V/1A. It refers to the related parameters of internal regulated power supply. And 100 V - 240 V refers to the input voltage and frequency. Under normal circumstances, as long as it's not special 110 V or 220 v standard cell phone chargers, it can be used in the whole world. Of course, it is worth mentioning that Jack standard is "European standard charger, USA Standard charger and national standard", please don't ignore the situation when you buy the charger.

According to the destructive experiment report of cell phone lithium battery provided by normal manufacturer, usually, battery core of the discharge conditions (including short circuit, etc) usually won't explode; it may be overheating and burning. But in serious over current charging situation, it is very easy to explode! So, to use a cell phone charger conforming to the safety standard is particularly important.

At present, "universal mobile phone charger" in the market marked that it can be used for 250 mah - - - 2500 mah batteries, actually it is very dangerous. They are lack of battery capacity detection and using fixed output current. For the different manufacturers' batteries, it has a different limit for input/output current. So it is possible to cause a too long time charging and over current charging. It is easy to cause safety accidents. So when users use this kind of cell phone charger, we suggest following the label on a cell phone battery and to see whether it accords with. Otherwise, the accident is only a matter of time.

And now USB mobile phone charger uses USB data interface as charging interface. So users need to concern the quality from USB mobile phone charger to mobile phone interface. The key is depends on the charging circuit design and material quality. So, we should choose to buy excellent design and safe quality products.
