Mobile phone charger

Mobile phone charger aka: mobile power charging treasure, actually made a steady power supply (mainly power supply, enough to provide a stable operating voltage and current) with the necessary constant current, voltage limiter, limit and other control circuits .

Mobile phone charger travel charger Original travel charger (refer to line charge) marked on the output parameters: for example, the output 5.0V/1A, output 5.0V/1500mA-11200 ...... refers to the internal power supply of the relevant parameters. Understand this truth, you will know it is a (good quality) mobile phone charger is easy to change a good quality power supply! Mobile common lithium-ion (li-ion) battery charger uses a constant pressure limiting charging system, charging current is generally used around the C2 ---- namely a two-hour charge rate, such as the use of 250mA rechargeable 500mAh battery for about two hours to reach 4. 2V then constant voltage charging. lion batteries are not suitable for -DV/DT detect fast charger NIMH Battery advanced fast charging method used, because lion battery charging current has strict limits. lithium-ion (Li +) is very lively, very easy to generate large current charging dangerous.

Phone charger can be roughly divided into travel charger, seat charger, USB charger and maintenance charger, is the latest mobile phone shell charger.

Mobile phone shell shell charger charger products and the overall appearance is no difference between an ordinary phone shell, mobile phone shell shell than ordinary GSM mobile phone charger charger phone shell shell thicker. With 2300mAh battery capacity, charging time can provide a complete, generally by lithium batteries or batteries as a power storage unit.

Other Charger USB Mobile Charger USB Mobile Charger average user contacts are two main front. The market is the largest selling travel charger, travel charger also has a form of variety, a common type of duck inexpensive mini travel charger, ordinary desktop card board charger, high-end desktop with LCD charge devices.

In view of the vast majority of mobile phone users are non-professional users, so the charger has stoped basic functions, and most belong to the fast charger travel charger, charging time is about 1-3 hours. Many chargers on the market are advertised himself microcomputer control, including some very cheap prices of duck Micro Travel Charger, in fact, from a rigorous analysis of the charging circuit, a small part of the charger in order to be known as microcomputer control (SCM) in the true sense .

Emergency charger mobile phone charger emergency charger mobile phone charger in the charging circuit some manufacturers use a manifold on the self-proclaimed "microcomputer control", in fact a lot of low-cost design chosen are inexpensive op amp Manifold Manifold , and some dedicated charging control manifold higher price, generally used for the charger or the brand's more upscale. So we can not believe in the so-called microcomputer control, especially cheap products. Many products look similar, but the internal wiring is quite different, its performance is also a big difference.
