Company Description

Mobile phone charger, pohongke qinzheng Technology Co., Ltdr adapter. To undertake the charger OEM/ODM, we have 3 fully automated assembly line, 4 artificial lines, complete equipment. Commitment to punctual delivery, reasonable price, quality is the facade of the factory!All mobile charger is actually composed of a stable power supply (mainly regulated power supply, providing stable working voltage and enough current), plus necessary constant current, voltage limiting, time limited control circuit.The original charger (refers to line charging) marked on the output parameters: such as output 4.4V/1A, output 5.9V/400mA...... Refers to the relevant parameters of the internal voltage regulator. With this in mind, you will know that a good mobile charger can easily be changed into a good quality regulator! For example, the output of 4.4V can be used for 4.5V devices, and 5.9V can be used for 6V devices......Mobile phone (lion) commonly used in lithium ion battery charger using the constant pressure limiting charging system, charging current generally used about C2 - use two hour charging rate, such as 500mah battery with 250mA charging about two hours to reach 4. Constant charge after 2V.Li battery is not suitable for -DV/DT detection using NIMH battery fast charger with advanced fast charging mode, because the lithium battery has strict restrictions on the charging current. The lithium ion (Li+) is very lively, very prone to the risk of charging current. [Performance characteristics:We can also check the performance of the charger during use. At the end of the charge, the battery has a slight temperature riseIs a normal phenomenon, but if the battery is obviously hot, it shows that the charger failed to detect in time the battery charging is saturated, resulting in overcharge, which is detrimental to the life of the battery.
