That is not the point. Lithium-Ion-Batteries tend to enter sudden thermal runaway specifically during charging.
The charger itself doesn't matter.
Chances are that this then causes a smoldering fire whose fumes gently kill you in your sleep...

Compromise rules in my family are therefore:

• No charging of cheap Temu-crap in bedrooms at all
• phones only charging on fire-proof bases without covering them (so no charging in bed...)
