A power strip is your friend when it comes to Christmas decorations, but use strips safely to avoid power interruptions and fires.
The typical household circuit can handle about 1400 watts. One power strip with six or eight outlets in use can well exceed the circuit capacity.
Desktop computers can use 60 to 300 watts per hour. Gamers will soak up power at the top end while regular school or work assignments may use the lower end, with 5 to 10 watts for sleep mode.
Inkjet printers will use 30 to 50 watts when printing. Commercial printers will use 300 to 500.
Never plug two powerstrips into the same wall outlet.
Replace any strip that feels warm to the touch.
Never daisy-chain power strips. In professional settings, that violates both OSHA rules and international fire standards. It is a fire hazard.
Don't use power strips outdoors. There are extension cords designed for outdoor use, but power strips should go indoors.
Turn off a strip when not in use.
