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...)
Basically all the Lego games (although 13y olds might already find them to child-like, depends...).
They all have split screen, so are suitable for couch (or desk) coop.
Also the slightly older ones are quite inexpensive when buying them during sales (a few €).
Special recommendation: Lego City Undercover.
Another fun couch-coop-capable game would be SuperTux, a Super-Mario-Cart like game.
This one is OSS and therefore completely free!
