Specifications:

  • Circuit board B- connects power negatively, B+ connects positive. Don't inversely connect, it will result in the burning of the board. Make sure there is insulation between power and circuit when installing the battery

  • 1A output is not continuous current, it changes according to USB connecting load, automatic current output as per load

  • If a battery is connected incorrectly, the reverse polarity will burn the circuit. So, make sure to check the battery polarity when connecting.

  • Input Voltage: 3.7V~5.5V | Output voltage: 5V | BAT Discharging Stop Voltage: 2.9V

  • Charging Current: 1A(max); Output Current: 1A(max); Discharging Efficiency: 85%(input 3.7V output 5V/1A)

  • Charging and discharging indication; Internally installed charging and discharging power MOS; Preset 4.2V charging voltage, precision ±1%; Max 8uA standby current;

  • Support trickle mode and zero voltage charging

  • Intelligent temperature control and overtemperature protection; Integrated Output overvoltage protection, short circuit protection, overload protection, overcharging and over-discharging protection

Note:

Charge indication of this power bank PCB board: When charging: red light flashing; Full charged: red light for a long time.

FAQ:

why the display percentage is not accurate, the battery power is only 50%, but it shows 80% after assembly?
Whether you are using a new battery or an old one all need to be discharged before use(charge your mobile phone), then turn it off charge it once again. If it still cannot be solved, it is caused by large internal resistance and inconsistent capacity.

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.
It is required to prime the IC so that it starts and shuts down accurately
