Will the crafty shut off by itself when receiving the "warning message" from the app? If not, can you ignore the message and keep using it or you have to let it cool down. So it will occur more often when using the boost mode.
So do I need to set the output voltage anything, or just insert the battery in and let it do its work. I see there is 3.7v 4.2 4.35v, if I use 4.2v what will happen? Sorry for weird question
