Ever wondered if you could make your smart devices even smarter by plugging them into a power strip with a smart plug? It may seem like a convenient solution, but is it safe? This is a common question among tech-savvy homeowners.
Can you plug a smart plug into a power strip, or will it cause problems? Here I’ll share details about using smart plugs with power strips and explore the potential issues you should be aware of.
Can You Connect Power Strips to Smart Plugs?
You can perfectly plug a power strip into a smart plug, as long as you stay within the wattage limitations. But be sure to check the wattage specifications of the power strip to avoid overloading it.
When using power strips and smart plugs together, make sure you’re aware of the maximum wattage to avoid damaging your devices. You should use common sense when deciding which devices to plug into the power strip.
Also, you should ensure that the devices connected to the power strip don’t exceed the total wattage of the smart plug. You can do this by simply checking the specifications of both your smart plug and your power strip.

Wattage Limits of Smart Plugs and Power Strips
When using smart plugs and power strips together, you should be aware of the wattage limits for both devices to ensure safety and proper functioning.
Let’s dive deeper into how you can determine if your smart plug and power strip are compatible and how to avoid any potential issues.
First, you’ll need to find the maximum wattage rating for both. Generally, smart plugs can handle between 1200 and 1800 watts, while power strips tend to have a maximum wattage of between 1200 and 2500 watts.
Knowing about the wattage, you can check the manufacturers’ websites or product information to find these ratings, or use the formula:
Max Wattage = Max Amps x Outlet Voltage (120 volts in the US)
You should not surpass these limits, as doing so could cause the devices to malfunction or pose a safety hazard.
When connecting a smart plug to a power strip, ensure the total wattage of all the devices connected doesn’t exceed the lowest maximum wattage rating between the two.
Although some household appliances, such as coffee makers, can use up to 1200 watts, you should consider each device’s individual power usage.
Moreover, always check your devices’ ratings and do your calculations, ensuring a seamless and secure experience while enjoying the benefits of smart home technology.
What Happens If You Exceed the Wattage Limit While Using Smart Plugs and Power Strips?
When you plug in devices with a higher wattage than what your smart plug or power strip can handle, a few things may occur:
- Overheating: Your smart plug or power strip may overheat, which can also result in the melting of internal components, leading to permanent damage and creating a potential risk for electrical fires.
- Circuit breaker tripping: If your smart plug or power strip is equipped with a built-in circuit breaker, it may trip to protect the devices and prevent damage.
- Reduced Power Supply: When the wattage limit is exceeded, it can lead to a reduction in power supply for the devices plugged in, causing them to malfunction or stop working altogether.
- Damage to Connected Devices: Excessive wattage can also harm the devices connected to the smart plug or power strip, potentially shortening their lifespan or causing permanent damage.
By staying within the recommended limits, you can safely enjoy the convenience and benefits that smart plugs and power strips offer.

How to Safely Use Power Strips with Smart Plugs
To ensure you’re using power strips and smart plugs properly, follow these five essential guidelines:
Check the wattage: Make sure the combined wattage of all devices connected to the smart plug and power strip does not exceed the maximum wattage. You should consider the demands of each device and ensure they stay within the limits of your hardware in order to avoid overloading or damaging your equipment.
Use quality products: To ensure the highest level of safety, it’s recommended to invest in reputable and well-reviewed smart plugs and power strips. High-quality products will typically have better safety features, reducing the risk of electrical fires or malfunctions.
Avoid daisy-chaining: Although it might be tempting to connect multiple power strips or extension cords together, this practice, known as daisy-chaining, can lead to dangerous circumstances. Always stick to connecting a single smart plug to a power strip, and never chain additional strips or cords together.
Keep it organized: You can keep your power strip cords and cables organized and untangled. This helps avoid accidental disconnections, damage to the cords, and potential tripping hazards. Investing in cable organizers or ties can assist in maintaining a tidy space.
Inspect regularly: Regularly check your power strips, smart plugs, and connected devices to ensure they’re working properly. If you notice any issues, address them immediately to help maintain safety.

Can You Plug a Smart Plug into a Surge Protector or Extension Cord?
You might be wondering if it’s safe to plug your smart plug into a surge protector or an extension cord. Yes, you can do this as long as you follow certain safety precautions and make sure you don’t exceed the maximum wattage allowed by these devices. You can read whether a surge protector prevents fire or not.
Again, you should check the maximum wattage capacity of your smart plug, surge protector, and extension cord. Most smart plugs are designed to handle a maximum wattage of 15 amps, or 1800 watts.
So, ensure that any device you plug into these smart plugs consumes power within this limit. The same goes for your surge protectors and extension cords. Double-check their maximum wattage capacity before plugging.
Also, always be cautious when using extension cords and surge protectors. While they may provide extra convenience, they can also face potential safety hazards, especially when handling high-power devices.
You can check the comparison between the surge protector and power strip to get a good idea about both.
FAQs
Yes, you can plug a smart plug into an extension cord. You should use common sense and good judgment when doing so. Make sure to check the wattage of your extension cord and the smart plug.
Never plug in devices that exceed the maximum wattage of the power strip. This includes devices such as portable air conditioners, space heaters, and other high-power appliances. Additionally, avoid plugging in appliances with heating elements, such as toasters and hairdryers, on a power strip, as they can create a fire hazard.
When voltage fluctuates, it can cause damage to your devices and appliances. If you notice voltage fluctuations, you should invest in a good surge protector to protect your devices and appliances from power surges. It is always best to unplug your devices during severe storms to prevent damage from lightning strikes and other electrical disturbances.
