A power strip can quickly become overloaded by power-hungry, often-cycled appliances like refrigerators. It is recommended to connect these gadgets to an electrical outlet that is specifically designed to power them. You run the danger of shorting out the circuit if you attempt to use the same outlet for more than one gadget.

2. Microwaves
The microwave is a culinary marvel because it cooks, thaws, and reheats food much faster than a regular oven. However, a power strip cannot supply enough energy for all that fantastic activity. A separate electrical outlet is required for the microwave, just as there would be for a standard electric oven.

The inside of a toaster consists essentially of a network of wires that are heated to extremely high temperatures in order to toast the bread. Anyone who has ever looked inside to remove a stubborn bit of crust knows this. A power strip can rapidly overheat due to the current draw of such wires. Electric skillets, toaster ovens, and waffle makers all have the same problem.
