Micro USB 3V 5V Two Voltage Mobile Power Module Battery Shield ESP32:
$25

Descriptions:
The module is a portable power bank that supports two voltage outputs of 3V/1A and 5V/2.2A. The rated current of 5V voltage
output is 2.2A, and the maximum support current is 3A (not recommended for overload, easy to damage the module,
and accelerate the service life). The output of the current depends on the quality of the battery.
Micro USB has a charging current of 600mA-800mA and supports up to two batteries. It is recommended to use two batteries,
which can be longer.
When the switch is turned to NOMAL, the current output is lower than 30ma, and it will automatically stop in about 10 seconds
and switch to standby mode.
When it is toggled to HOLD, no matter what happens, it will remain on until the battery is dead (the 2512 resistor on the back will heat up).
Special Attention: The battery must be installed with positive and negative poles. The positive and negative poles are clearly marked
on the board, and incorrect installation will burn the module.
