charger
Mobile phone chargers can be roughly divided into travel chargers, cradle chargers and maintenance chargers. Generally, users mainly contact the first two. And the most sold on the market is the travel charger.
There are also various forms of travel chargers. The common ones are the cheap duck egg-shaped miniature travel charger, the ordinary desktop card board charger, and the high-end desktop charger with liquid crystal display.
Mobile phone charger, also known as: mobile phone adapter, is actually composed of a stable power supply (mainly regulated power supply, providing stable working voltage and sufficient current) plus necessary control circuits such as constant current, voltage limiting, and time limiting. The output parameters marked on the original charger (referring to the line charger): such as output 5.0V/1A, output 5.0V/1500mA-11200... refers to the relevant parameters of the internal regulated power supply. Understand this truth, you will know that a (good quality) mobile phone charger is easy to change into a good quality regulated power supply.
The chargers of lithium-ion (li-ion) batteries commonly used in mobile phones use a constant-current and voltage-limited charging system, and the charging current is generally around C2—that is, the charging rate is two hours. For example, a 500mAh battery is charged at 250mA in about two hours 4. Constant voltage charging after 2V.
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 (Li ) is very active, and high current charging is prone to danger.
Mobile phone chargers can be roughly divided into travel chargers, dock chargers, USB chargers and maintenance chargers, and the latest is the mobile phone case charger.
The overall appearance of the mobile phone case charger is the same as that of the ordinary mobile phone case, and the mobile phone case is slightly thicker than the ordinary mobile phone case. With a 2300mAh battery capacity, it can provide a complete charge, usually a lithium battery or dry battery as a power storage unit
