> but why would you have such habit even when stationary and the charger is lying around?

Two reasons - One, the charger heats up a lot when I keep it on. Of course, you don't feel it unless you are nearby or touch it. Two, in the past I once had the charger destroyed due to a power surge. The Macbook remained fine after that power surge but I had to replace the charger since it stopped charging after that.

About the heat: I have a MacBook Pro M1 16" and a third-party 65 W charger, it barely gets warm, far from even recognising by being close to it. Perhaps you should get a better charger if it heats up so much. The one I'm using: https://www.amazon.com/Charger-Baseus-Adapter-Delivery-Folda...

I'd advise against buying any kind of charger, battery, or frankly anything that you'd be leaving plugged in unattended on Amazon.

Yep, most of them have 4.8 star reviews, but if you look through you can usually find quite a few that caught fire.

Checked the reviews for this particular one, no one is mentioning fire. If you search for Apple charger caught fire you will find some, can happen to any electronic device.

I have three of them plugged in 24/7 for 3 years now and recommended them to others, all houses still standing. But you can also get the original 96 W charger from Apple, it's bigger so it can dissipate heat better than the smaller ones.

I would not trust reviews on any site that's incentivized to sell me something, but especially not Amazon which allows sellers to edit listings and put completely different products while keeping the reviews (not to mention inventory commingling so that even buying a legitimate product won't save you).
