Power strip: 9 devices that should never be plugged in (you risk a fire). (Page 3 ) | April 9, 2025

A washing machine consumes on average 1150 kWh per year. It is therefore a very energy-intensive device and therefore not recommended at all for a power strip.

Plugging the washing machine into a wall outlet avoids any risk of short circuiting and overheating of the extension cord. The same goes for tumble dryers. They consume way too much electricity to leave them plugged into a power strip.

4. Auxiliary heating

consuming device is auxiliary heating. I’m not telling you that you shouldn’t use it, but remember to plug it directly into a wall outlet. Never on an extension cord, because this device very quickly overloads the power strip.

5. The microwave

Don’t believe that this little metal box doesn’t consume any energy. A microwave can consume on average 70 kWh per year. You see, it’s not nothing. You should therefore avoid plugging it into an extension cord.
