How Many Watts Can a Power Strip Handle?

If you’ve ever plugged multiple appliances into a power strip, you may have noticed that some of them do not work. Some appliances use more power than others, which can cause the strip to trip its circuit breaker.

Also, the average surge protector can support at least three electronic devices! In most cases, a typical power strip can handle a laptop and a monitor without a problem. It can also run several low-power devices, such as a printer and speakers.

So the question is, what wattage can a power strip handle? I’ll reveal the answer.

How many watts can a power strip handle safely?

It is difficult to answer the question since it depends on how many watts per outlet should I use? The manufacturers of power strips do not publish the wattage rating of every outlet because they want to give you as many options as possible.

Although power strips support many devices, not every device requires a high wattage. For example, a single space heater or a single floor lamp would not require a high-wattage extension cord, and the power strip attached to that outlet could handle many devices.

Even your coffee maker, which might need 1200 watts or more, could be protected with a quality surge protector power strip with at least 800 joules of protection.

The average 120V power strip can handle 1800 watts. Remember not to plug more than two high voltage devices into one power strip at a time.

In this case, I recommend using “heavy-duty” power strips for computers, entertainment centers, and home offices. The heavy-duty power strips support more devices than standard power strips and offer superior safety features.

How many watts can a wall outlet handle? 

While a wall outlet provides a steady 120 volts of electricity, the amount of electricity it can deliver varies based on how much electricity is being used by other appliances in the house.

When you have a lot of devices on at once, your outlets might not be able to support the amount of electricity needed. Overloading the outlets could cause them to overheat, resulting in a fire or damage to your appliances.

In general, you should avoid using more than 1,500 watts per outlet or circuit.

Average 110 V power strip can handle 550 watts
Average 120 V power strip can handle1800 watts
Average 220/240 power strip can handle 4000 watts
***Watts capacity depends on power strip quality.

Can I power a gaming pc off of a power strip? 

Yes, but if you’re using a standard power strip, the answer is no. This is because the traditional power strips are designed to accommodate the fewest number of devices, as I have talked about previously in this article.

Gaming PCs use high-wattage components, such as graphics cards that can draw 300 watts or more. If plugged into a standard power strip, these components would cause the strip to shut down. In this case, a heavy-duty surge protector should be able to protect all your components.


In general, the amount of energy your device consumes won’t be a problem on its own. In any case, you should never use devices that draw more power than your strip can handle.

Also, when you plug in too many appliances, you may cause an electrical fire or damage your device. I hope you find the answer to your question in this article.
