Charging Power bank with fast charging ouput and Overcharge protection

Over-voltage protection: Regardless of whether it is fully charged or not, if the voltage exceeds the default value due to charging, it will stop charging. This is often called over-charge protection, but technically, over-voltage can occur even if it is not fully charged.

Over-discharge protection: When over-discharged, the battery voltage is equal to or lower than the set value to stop discharging. Over-current/short-circuit protection: Stop discharging (turn off the output) when the current is too large or a short-circuit occurs.

Over-temperature protection: Reduce the charging speed or stop charging and discharging when the battery temperature is higher or lower than the set value (or both can be used).

Power bank

It is a portable charger that can be carried with you, can store electrical energy by itself, and is mainly used to charge consumer electronic products (such as wireless phones, laptops) such as handheld mobile devices. It is especially used in the absence of external power supply occasion. Its main components include: a battery used for electrical energy storage, a circuit for stabilizing output voltage (DC-DC converter), and a charger circuit for charging the built-in battery. There are very few mobile power sources without a charging circuit, but they are almost extinct.

Lithium-ion batteries or lithium-ion polymer batteries are prone to permanent damage or fire due to improper placement. Therefore, if lithium-ion batteries or lithium-ion polymer batteries are used, special protection circuits must be provided to prevent damage or danger. The required protection must include:
