I'm using ESP32 to run 4 IR obstacle sensors and send the reading to firebase.
I did the power calculations as follows :
4 IR sensors
4 x 43 mA = 172 mA
1 ESP32 = 500mA
So the total current = 672 mA.
When I powered the circuit with power bank 5000mAh with output 5V/1A (5v/1000mA). It works but it does not connect to WiFi. I tried power bank with 5/2.1A it works fine.
But I tried my friend's esp32 (same module) it works with the first bower bank(5V/1A).
So what is the problem with my ESP?
