- 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.
You won't get best rates for a decent item elsewhere along with better service, standard quality and support too.
