## Description

SpecificationsInput Parameter: 5V/2AInput Interface: micro USBOutput Interface: dual USB output: 5V/1AConversion Rate:90% averageCharging Display: When charging, battery level 0-25% one light is on,other lights off;25%--50%,the second light flashes,the first light is continuously on;50%-- 75%,the third light flashes,front two lights are continuously on;75%---100%;the fourth light flashes,front three lights are continuously on.And four lights are on charging to 100%.Main board Protection Function:Overcharge protectionOverdischarge protectionOvercurrent protectionModule does not need battery protection board as it has inbuilt battery protection system.Installation Intstructions:1.Circuit board B- connects power negative,B+ connects positive. Don't inversely connect,it will result in burning of board.Make sure there is insulation between power and circuit when install the battery2. Press and hold the switch,flashlight LED light starts,then press and hold to turn it off3. 2A output is not continuous current,it changes according to USB connecting load, automatic current output as per load4. If battery is connected incorrectly, the reverse polarity will burn the circuit.So, make sure to check the battery polarity when connecting.Special Instruction:When connecting the board for the first time, connect the battery and then connect the micro USB charger and charge the battery to full capacity before using.It is required to prime the IC, so that it starts and shuts down accuratelyNote:Please allow 1-3mm error due to manual measurement.Due to the difference between different monitors,the picture may not reflect the actual color of the item.Package Includes:1x Power Bank Charging Board
