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

  • Press and hold the switch, flashlight LED light starts, then press and hold to turn it off

  • 2A output is not continuous current, it changes according to USB connecting load, automatic current output as per load

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

Characteristics:

  • Input Voltage: 5V | Input Current Rating: up to 2.5A | Input Interface: Micro USB | Can use any mobile power supply rated 5V

  • Output: 5V 1A or 5V 2.1A | Output Interface: Dual USB output: 5V/2.1A

  • 4 onboard SMD LED to display battery charge level; Separate 5mm LED to use the power bank as a torch

  • Designed for 18650 battery DIY power bank: The battery of the 18650 battery must be flat, and the length is 65MM. The pointed battery cannot be used. If you are using old batteries, different capacities, different brands are not available, the assembled battery is guaranteed to be at least 3.5V per voltage. If the voltage is too low, it will not be charged. (It also support lithium battery, mobile phone battery, and tablet battery)

  • Overcharge protection | Over-discharge protection | Overcurrent protection | Supported connection methods: It is possible to connect only one lithium battery or multiple lithium batteries in parallel. The capacity of the connected battery is no more than 200,000 mAh, As long as the battery with a voltage of 3.0-4.2V can be used.

Note:

Charge indication of this power bank PCB board: The word "IN" will be shown in the display; Output indication: Long press the LED button after turning on the load, Start output, The word "OUT" and the current and voltage of 5V 1.0A or 5V 2.1A will be displayed in the display.
The positive pole of the battery is connected to B+ and the negative pole is connected to B-, do not reverse it. If it is reversed, it will burn out!!!!

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
