Can I leave the appliance on after I check out?

It is dangerous to leave the appliances on after checking out.

As long as the appliance is electrified, there will be current. After a long time, no matter how much electricity is used, it will be dangerous to use electrical appliances to heat up.

If you have gone far, call the landlord to explain the situation and ask the landlord to turn off the electrical appliances to ensure safety.
