Description:

• 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 1000mAHcurrent 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 highlike 5.2vthe current will be less than 1000mAit is normal. It is protection functionauto-substract the charging current to avoid burn damage to chip.
• NO Reveral polarity.

Size: Small to 25X20X5mm.
