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.
