Product Features:

Small size

Support Type-C interface power supply, compatible with most PD fast charging heads

1A high current linear charging

With protection board function

Input voltage range: 5~6V

Output voltage: 4.2V

Charging current: 1A

Features:

When the charging current drops to 100mA after reaching the final float voltage, the charging cycle will be automatically terminated.

When the battery voltage drops below 4.05V (roughly corresponding to 80% to 90% of the battery capacity), the charging cycle restarts.

When the battery voltage is lower than 2.9V, the battery will be precharged with a current of 100mA.

With protection board, over voltage protection, over discharge protection, over current protection. Over-discharge protection value: 2.4V; over-current protection value: 4A.

You need to connect the power supply to activate the protection board for the first use.

Board size: 14×18×5mm (Type-C port female seat protrudes about 1.5mm)

Package： 10PCS
