This power bank supply has a built-in lithium battery protection IC with overcurrent, overvoltage, Undervoltage, etc.

USB port output and mobile power board have extended port 3V and 5V output ports to facilitate customer needs and use, greatly reducing the problem of fewer ports

The 4-level LED light shows the power. The default power-on is always working. It needs to be manually turned off. (If you need to change to the non-working state automatic shutdown mode, just cut the middle line of the “NC” bit or remove the “ROUT” resistor. can)

Do not reverse the positive and negative, human factors cause damage at your own risk, do not reverse

The battery voltage works normally at 3.2V-4.2V. Do not connect the batteries in series. The series connection will increase the voltage. If the battery capacity is increased, the battery can be connected in parallel. Do not connect in series.

When the battery is reinstalled, the chip may detect the power-off protection mechanism. It needs to be recharged and activated. This is normal!
