TP4056 Lithium Battery Charger Module

• 100% brand new and high quality
• 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.
• Input interface: Micro USB
• Working temperature: -10° to +85°
• Inversed polarity: NO
• 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 to chip.
• NO Reveral polarity.
