TP4056 5V / 1A Mini USB Lithium Battery Charging Module

• 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 blue is full charged
• Input interface- mini USB
• Work temperature- -10℃ to +85℃
• Inversed polarity- NO
• Size- small to 25X19X10mm

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-substract the charging current to avoid burn damage the chip.
