K02
Specification:
100% brand new and high quality
Charge module- Linear charging.
It has MICRO USB female
It still retain the input voltage wiring solder joints, can be very convenient to DIY

Specifications:
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- micro USB.
Work temperature- -10℃ to +85℃.
Inversed polarity- NO.
Size: 27X17mm.

NOTE:
1. Ampere meter can only be connected to 5v input end of the module.
2. 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.
3. The connection wire should not be too thick.
4. Make sure the connect point is good.
5. 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.
6. NO Reveral polarity.
Warmly tips:
1.when use this module at first time, there may be not voltage output between OUT+ and OUT-, it need connect the 5V power supply to active the circuit, When the battery disconnect with this module and connect it again also need this step.
2.When use the phone power adapter as the input power supply, it need the power adater output current is over 1A.
Package Included:
1 x 5V Micro USB 1A 18650 Lithium Battery Charging Board Charger Module
