I never knew this!!

Air conditioners, space heaters, toasters, and other appliances that use high wattage can easily cause power strips to overheat, which can easily lead to a fire hazard.

Even before plugging anything into a power strip consider the ammount of power they support. This is usually listed on the product itself.

High-capacity appliances need to draw a lot of power through an electrical circuit to work. Keep in mind that an appliance does not need to be large in size to draw large amounts of power.
