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.
They don't have the right item but when customer call for replacement they will say they don't have for this statement they will hold the customer call they will put in mute later they will say they don't have all are faulty item I've ordered for micro SD to micro SD but they have shipped SD to SD they are not ready to listen to the customer need also.
It is a great product for what it offers. The digital zoom is where it falls short in its clarity being digitally zoomed, but not very bad.
The optical lens is is brilliant.
Overall a great product at this price point.
