Do Not Unplug These 7 Household Devices: Why It Doesn’t Save Money — and May Even Cause Damage
Unplugging household appliances is often seen as a smart way to save electricity. Many people believe that pulling the plug automatically lowers energy bills and protects devices. However, this habit is not always as beneficial as it seems. In fact, unplugging certain devices can waste more energy, shorten their lifespan, or even cause damage.
Here are seven common household devices you should think twice about unplugging, and the reasons why leaving them plugged in can actually be the better choice.
1. Wi-Fi Router
Your Wi-Fi router is designed to stay on continuously. Unplugging it frequently forces the device to restart and reconnect to your internet service provider, which can stress internal components over time. Routers also use very little electricity, usually less than a light bulb.
Turning it off regularly may lead to slower internet speeds, connection instability, and reduced lifespan. Unless you are leaving home for an extended period, keeping it plugged in is the smarter option.
2. Washing Machine
While it may seem logical to unplug a washing machine when not in use, doing so repeatedly can be harmful. Modern washing machines contain electronic control boards that rely on stable power. Frequent power cuts can disrupt these systems and increase the risk of malfunction.
Additionally, unplugging does not significantly reduce electricity costs, since washing machines consume power mainly during active use.
3. Refrigerator
A refrigerator should never be unplugged unless absolutely necessary. Its compressor is designed to maintain a consistent temperature, and cutting power can cause temperature fluctuations that strain the motor.
Repeated unplugging may also lead to food spoilage, increased energy use during restart, and long-term damage to the cooling system.
4. Smart TV
Smart TVs often run background updates and system optimizations when on standby. Unplugging them prevents software updates and can cause system errors when powered back on.
Moreover, modern TVs use very little power in standby mode. Constantly unplugging may actually wear out power ports and internal circuits faster than leaving the device plugged in.
5. Desktop Computer
Desktop computers are sensitive to sudden power interruptions. Unplugging them without proper shutdown can corrupt files, damage hardware, and reduce performance over time.
Even when fully shut down, desktops consume minimal standby power. Using a surge protector is a safer and more effective way to manage electricity and protect your computer.
6. Microwave Oven
Microwaves draw almost no power when idle. Unplugging them repeatedly can damage the internal clock and control panel, especially in digital models.
The small amount of electricity used to keep the display active is negligible compared to the cost of repairing damaged electronics.
7. Modem and Network Devices
Like routers, modems and network hubs are designed for constant operation. Frequent unplugging can interrupt firmware processes and reduce signal quality, leading to unstable connections.
Network devices consume minimal energy and benefit from uninterrupted power for optimal performance.
Why Unplugging Doesn’t Always Save Money
The idea that unplugging everything reduces electricity bills is outdated. Most modern appliances are energy-efficient in standby mode, consuming only a few watts per hour.
In contrast, restarting appliances often requires a surge of power, which can cancel out any small savings from unplugging.
What You Should Do Instead
Rather than unplugging devices randomly, focus on smarter solutions:
-
Use surge protectors to protect appliances from power spikes
-
Turn off devices properly using their power buttons
-
Unplug only rarely used appliances, such as seasonal heaters or old electronics
-
Invest in energy-efficient devices with low standby consumption
Final Thought
Saving energy is important, but not all habits lead to real savings. In some cases, unplugging household devices can cause more harm than good.
Understanding how your appliances are designed to operate helps you make better decisions, protect your devices, and avoid unnecessary repair costs.
Sometimes, leaving the plug in is the smarter move.
