I just got a new tenant in my rental house and this time I had to add a clause to the lease enumerating brands of lithium-ion batteries the tenant is allowed to keep on the premises. These things are basically grenades that you can buy for $2 on Temu. Stronger regulations needed.

I'm not a landowner, but (subject to the local laws of course) I imagine a safer course of action would be decent home insurance. Realistically, there's a thousand other ways things can go disastrously wrong, including nothing that could be the tenant's fault (like natural disasters).

Batteries? Picture a fondue going wrong.

I'd like to argue that electric Rechauds are superior anyway. Fuel paste or gas always seems to run out just before you're finished, everything cools down while refilling and then you have to get the fluid up to temperature again. Safety around children or tipsy people is just the bonus on top.
