High-Powered Appliances: Items like space heaters, toasters, and microwaves draw too much power and can cause overheating, posing a fire risk. Air Conditioners: Like high-powered appliances, air conditioners require more energy than a power strip can safely handle. Refrigerators/Freezers: These large appliances need constant power and can overload a power strip, leading to potential damage. Medical Equipment: Essential devices like oxygen machines and CPAP machines should be plugged directly into a wall outlet for reliable power. Hair Dryers or Curling Irons: These devices consume a lot of energy and could overload the power strip, leading to a fire hazard. Power Tools: Whether it’s a drill, saw, or other heavy-duty tool, these items require more power than a power strip can safely provide. Large Entertainment Systems: While TVs, sound systems, and gaming consoles seem like they might be fine, their combined wattage can quickly exceed the capacity of most power strips. Fridges or Freezers: These appliances often require a steady flow of power and can overload a power strip, possibly causing it to fail. Multiple High-Wattage Devices: Don’t plug several high-wattage devices like space heaters, coffee makers, and irons into one power strip—this can overload it, triggering a short circuit or fire
