This is a portable power supply that could output 3V / 1A and 5V / 2.2A dual voltage.
5V output rated current is 2.2A, maximum support 3A current (not recommended), the output of current also depends on the quality of the 18650 battery used.
The Micro-USB draws 600mA-800mA when it is in Charging.
Supports up to two 18650 batteries (highly recommended)
Notes: Pay attention to the + and – polarity when install a battery, do not reverse, otherwise it will damage the unit.
