Shenzhen GEO Technology Co.,Ltd | Updated: Aug 23, 2016

Mobile phone charger can be divided into travel charger, charger, USB charger and maintenance type charger, latest is phone case charger.

General users is the front two kinds of contact. And sold on the market is the largest travel charger, travel charger also has a wide variety of forms, common type of cheap duck micro travel charger, ordinary desktop card charger, high-end desktop charger with LCD display. In view of the vast majority of mobile phone users are non-professional users, so the Chargers have full automatic stop function, and most of the travel are quick charger, charging time is about 1-3 hours. Many Chargers have prides itself on the market with micro-computer control, including some very cheap duck mini travel charger, but strictly from the charge circuit analysis, a small part of the charger can be truly called micro-computer control (controlled by single-chip microcomputer).

Charging circuit, some manufacturers use the manifold block itself as the "microcomputer", in fact, many low-cost design of manifold block is chosen cheap amplifier chip, and some special charging control chip of the high price, are generally used for more upscale or brand-name charger. So we can't believe the so-called micro-computer control, especially of cheap products. Many products look similar but the internal wiring is very different, its performance is also different.
