I’m not planning to use it for real since I didn’t trust it myself and thanks for the link I’ll have to try it out later

this powerbank can output varied output (4.5v - 12v) and it’s a fairly high quality powerbank

the battery died and I connect powerpack to phone’s battery terminal

actually the powerpack have varied output (4.5v5a - 12v1.5a), I’m not planning to use this for real I just wanna see if it work or not since the powerpack and phone battery output the same DC current

I connect powerpack to the battery terminal
