Li-ion

• This module is a portable mobile power supply that supports 3V / 1A and 5V / 3A two voltage outputs
• This mobile power supply has a built-in lithium battery protection IC, which has overcurrent, overvoltage, under-voltage, etc.
• 4 level LED lights show power, the default boot is always in working state, you need to manually shut down (if necessary, change to non-working state automatic shutdown mode, just cut off the middle line of the “NC” bit or remove the “ROUT” resistor)
• LED indicator(Green means full, Red means charging)

Note:

5V voltage output rated current is 2.2A, maximum support 3A current (not recommended for overload, easy to damage the module, speed up the service life)
