Thank you for the fast delivery
1. It turns off when the power consumption is minimal. I need that low power for my ESP32! 2. It doesn't turn on when I apply external charging onto the battery terminals. 3. If I use internal charging system, it temporarily disables 5V output, for almost 500 milliseconds, which is very stupid, I need *continuous* power, thats why I'm using 18650 batteries, HELLO? 4. It never turns itself on unless you press the stupid button OR remove/insert the battery. Very poor electrical design, completely unusable for ANY DIY project, unless you're OK with re-inserting the battery each time it stops working.
