If you mean “9 things you should never plug into a power strip,” the basic rule is: avoid putting high-wattage, heat-producing, or major appliances on an ordinary power strip. Fire-safety authorities recommend plugging major appliances directly into wall outlets and not overloading power strips.
⚡ 9 things to keep off a power strip
- Space heaters — They draw a lot of current and can overheat a power strip. Plug them directly into a wall outlet.
- Microwaves — High power demand makes a standard power strip inappropriate.
- Refrigerators/freezers — Major appliances should be connected directly to a wall receptacle.
- Washing machines and dryers — These are high-demand appliances and should have appropriate direct connections.
- Air conditioners — Their high electrical load makes power strips a poor choice.
- Toasters/toaster ovens — Heating elements can draw substantial power.
- Coffee makers — They are heat-producing appliances and can place a heavy load on a power strip.
- Electric kettles — Their heating elements can draw high current.
- Air fryers — Because they are high-wattage heating appliances, plugging them into a standard power strip can overload it.
🚨 One more rule people often miss
Never plug one power strip into another power strip or extension cord (“daisy chaining”). It can overload the electrical system and increase fire risk.
