Power Bank that supplies 5V to a circuit
I have a voltage regulator to 3.3V that feeds a circuit with a PIC and a LoRa Module, the circuit transmits for 10 seconds and remains sleep for 5min, has a total current consumption of 16mAh. If the circuit is powered from the USB port of the PC it works continuously, but if I connect it to a Power Bank it only works the first 5 minutes. What can I do so that the Power Bank does not shut down?
Thanks and Regards
