5V 1A Micro USB 18650 type-c Lithium Battery Charging Board Charger Module w Protection

Description
• This module uses a very mature charging chip TP4056, with simple peripheral circuits, good protection performance, and high charging accuracy.
• The current of this module can be adjusted by yourself, as long as the fixed resistance in the circuit board is changed, the output can be changed to 100 mA-1000 mA.

Specifications
• Input interface: Type-c USB
• Charge module- Linear charging
• Current- 1A adjustable
• Charge precision- 1.5%
• Input voltage- 4.5V-5.5V
• Full charge voltage- 4.2V
• Led indicator- red is charging Green is full charged.
• Work temperature- -10° to +85°
• Inversed polarity- NO
NOTE:
• Ampere meter can only be connected to 5v input end of the module.
• It is better that the charging current is 37% of the battery capacity.
• If you charge to the battery of 1000mAH, current of 400 is enough.
• The connection wire should not be too thick.
• Make sure the connect point is good.
• If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-subtract the charging current to avoid burn damage to chip.
• NO Reversal polarity.
