You can determine the wattage by checking the plug label or manufacturer's instructions to calculate the total combined wattage per outlet.

How Many Things Can I Plug Into a Power Strip?

How many things you can plug into a power strip depends on its amperage , and you can use the Ohm's Law calculation of amps multiplied by volts to work out its capacity. Of course, you'll also be limited by the number of outlets on your strip. If you want to use the power strip to plug in low-wattage items such as phone chargers, you can probably safely plug in multiple devices without causing an overloaded outlet. However, it's always safest to add together the wattage of each appliance and device and avoid plugging a power strip into the same outlet that supplies a high-power appliance.

Why is it dangerous to overheat an electrical circuit?

According to the National Agricultural Safety Database , overloaded outlets are a leading cause of house fires. Plugging in more appliances than the circuit can handle causes it to overheat and leads to damaged wiring. The heat combined with a damaged electrical system is dangerous because it significantly increases the risk of an electrical fire.

A typical American 15 amp 120 volt receptacle is rated at 15*120=1800 watt. However, for a continuous load we need to reduce that to 80% per NEC. That gives you 1440 Watts. So the politically correct answer is 1440 Watts. Now, I will say not all receptacles are created equal. A commercial grade receptacle you buy for $5 each will do that all day, while the $.98 economy items have a tendency to look like the picture above if you plug an 1800 watt space heater in for the night.

What is a power receptacle?

Power receptacles are generally designed to handle at least 125% of their rated power/voltage/current. Commercial-grade receptacles are more rugged, and their socket contacts are designed for many more life cycles.
