Problem with powerbank with ESP32

Postby NBAntony13 » Fri Jan 18, 2019 2:04 pm

I tried to use this powerbank Wich I attach, but it doesn't work with ESP32. Maybe I'm missing something, but I can't understand what's the problem. To your knowledge, is it possible to use any powerbank to supply ESP32? If it is possible , do you have any recommendations for the model and others?

If you added an attachment, I think it failed... not seeing it here. Furthermore, it helps if you state what issues you're seeing (serial output?)

I am not saying this is the problem, but I have seen power banks that will not power up deices if the load is not high enough.

Also, on some boards, you need to manually reset the ESP32 before it properly powers on in the user application. Can you try that?

Yes. I have had no success using power banks as a power source for ESP8266 or ESP32 for this reason. As soon as the consumed current drops below some level, the battery thinks the "phone" is fully charged and turns off the charging output.

Can I use other device for give power to ESP32?

P.S. thanks for the replies, I appreciate it
