What Is The Danger Of Not Unplugging The PD Power Adapter?

Many people have little time to charge their mobile phones due to their busy work during the day. So I often lie on the bed at night and use Douyin, and plug in the charging cable while playing with my mobile phone. One charge is one night. In the morning, I unplugged the phone, put it in my pocket and left. The PD power adapter has been left in the socket. What harm is there in doing so?
After the mobile phone is unplugged, some PD power adapters are in an interrupted state, and there is no current inside them. It doesn't matter if this kind of adapter is unplugged or not, but there are some PD power adapters, even if the phone is unplugged, the indicator light will still be on, and there is current inside to form a loop. Going like this for a long time will waste a lot of electricity and increase the monthly electricity bill burden. Life is not easy, and it is difficult to beat workers. Unplug the plug at will, and save as much as you can!
Secondly, if you use a low-quality PD power adapter produced by a small manufacturer, the safety quality is not up to standard, and you keep plugging it into the socket, it will cause a great safety hazard. If people are not at home during the day, if the adapter is short-circuited, it is likely to cause a fire, which is very dangerous. So we usually pay attention when charging, one is to buy a genuine power adapter, and the other is to cut off the power and unplug the charger when not charging.
