Features:
Input Voltage: 5V
Current: 1A
Charging Cut-off Voltage: 4.2V/4.35V optional; Input Interface: Type-C USB
5-6V power supply, applicable to a single lithium battery (parallel connection is not limited), the default 1A current.
Applicable to all types of 3.7V lithium batteries.
Small size. Smaller than similar products.
The use of the scope: lithium charging DIY, small electrical appliances conversion, tablet PC with charging port, small power power equipment.

Notes:
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 405V (roughly corresponding to 80% to 90% of the battery capacity) the charging cycle starts again.

When the battery voltage drops below 2.9V, the battery will be pre-charged with 100mA of current.

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

Red light when charging, blue light when full.

The battery can not be reversed, reverse connection damage to the motherboard; The battery terminal voltage can not exceed the product overshoot voltage; The battery can not be connected in series, only in parallel, the number is not limited; The first time you need to connect the power supply to activate the protection board.
