I'm renting a room from a woman and the power is 220 Volts. More than
once she has scorched one pin of her room heater's plug. The last

halves.

I replaced the plug too and pointed out that if the receptacle is
loose, that's a problem too. She showed me that her bedroom socket
barely grips the plug or not at all.

She hasn't asked me yet to replace the whole socket, and even if I
did...

I'd be real careful about fiddling with electric or anything else
that has the potential for big problems in a place you're renting.




the apartment was wired for internet cable, so it must have
been remodeled not that long ago, and I'm guessintg the electric
sockets were replaced too (I can ask her.)

Because you add internet you must have been remodeled and upgraded?



So.... Is there a device one can put into a 220v. socket (receptacle)
that will expand and make a tight connection with a loose socket?


No


Or any other way around her problem?


Why doesn't she just call an electrician and get if fixed before she
kills someone?





Also, I brought an American extension cord with me, so I would only
need one adapter for the computer, the camera charger, the phone
charger, and the earpiece charger, all of which together don't use
that much iirc, but somone tells me a US extension cord might not be
able to handle 220v. What say ye?

I would think the insulation on typical US extensions would be good
to 220V+
