Description of Wall Charger

 
 Mobile phone chargers, also known as mobile power supplies and du power banks, are actually composed of a stable power supply (mainly a stable voltage power supply, providing a stable working version for voltage and sufficient current) plus necessary constant current, Control circuit composition such as voltage limit and time limit. The output parameters marked on the original  charger: for example, output 5.0V/1A, output 5.0V/1500mA-11200...refer to the relevant parameters of the internal regulated power supply.
 
The chargers of lithium-ion batteries commonly used in mobile phones use a constant current limit voltage charging system, and the charging current is generally about C2-that is, a two-hour charging rate. For example, a 500mAh battery uses 250mA to charge for about two hours to 4.2V Constant voltage charging.
 
The lion battery is not suitable for the -DV/DT detection fast charging method used by the NIMH battery advanced fast charger, because the lion battery has a strict limit on the charging current. Lithium ion is very active, and high current charging is prone to danger.
