3. Washing Machine: When turned on, washing machines pull a lot of power. This is the main reason why these appliances shouldn’t share a receptacle with any other appliance or device.

Most washing machines use a max of up to 1400 watts, putting it dangerously close to the max load of most power strips. On top of that while working, washing machines are usually left unattended and work longer hours, at least an hour, which is long enough for a power strip to overheat.

4. Heating: Portable heaters should never be plugged into a power strip because most of them use 1,500 watts of energy on their high setting and they usually run for extended periods of time.
