I just tried plugging my phone charger into a wall.
The charging cable is partially broken and my phone is old and has a hard time getting charge in the internal plug too.
So, I had it plugged into my laptop but it needs almost 4h and was in the way of me using my laptop, so I went to try a wall plug....
Smoke instantly started coming out from where the cable is cracked...
So, 4 hours to charge through my laptop sounds like a great idea!!! 😬😅
