Power strips add outlets, not electrical capacity, so heat-producing appliances like space heaters, toasters, hair dryers, coffee makers, and most slow cookers belong in wall outlets. If a strip feels warm, smells burnt, buzzes, or shows discoloration, stop using it and check the outlet and cord.
Essential Concepts
Power strips do not raise circuit capacity.
Use wall outlets for heat and heavy loads.
Keep an eye out for heat, smell, buzz, or discoloration.
