Will using a cigarette lighter to charge a cell phone damage the battery?

Mobile phone batteries are lithium batteries. When charging a lithium battery, it is usually charged first with a constant current, at which point the voltage increases rapidly when it is almost full, it is charged with a constant voltage. and a small current, and the current will exceed becomes smaller and smaller, and when the current reaches a value set by the battery protection circuit board, charging stops.

The car cigarette lighter charger is generally a 12V to 5V device. As long as the charger has the above functions, the battery will not be damaged. In addition, the cell phone battery itself has its own protection circuit. Car cigarette lighter chargers available on the market can be used with confidence.

Generally, ordinary USB electronic lighters sold on Taobao need 2-3 hourscharging to be fully charged.

This is mainly due to the selection of power chips and lithium batteries.

The ASIC chip used in our electronic cigarette lighter MCU is an application-specific integrated circuit. The lithium battery management chip uses a dedicated two-in-one charge and discharge management chip that integrates three-stage constant current and constant voltage charging management. The battery uses a lithium cobalt oxide battery. It can be fully charged in half an hour! Learn more
