Extension Cord With Timer – Top 4 Picks In 2023

An extension cord connects an electrical power cord to an outlet in your home if the primary cable is too short. Extension cords can range from 2 to 100 feet in length. The direct benefit of purchasing an extension cord with a built-in timer is that you can control when your appliances turn on and shut off by programming the timer, similar to the outdoor extension cord with switch but it has more control even when you are not there.

This feature is beneficial in situations such as Christmas light setups. It can drive your electric bill through the roof if they run all night and can even be dangerous. Maybe you’re on vacation, and you want your lights to turn on in the evening and cut off or dim in the morning to establish a pretense that someone is home. The possibilities are endless.

With all that said, there are tons of models and types to choose from, so check out this list to help you find the best extension cord with a timer.

Difference Between a Digital and a Mechanical Timer?

Mechanical timers are larger than digital switches and can withstand heavier electrical loads. Generally, they are large metal boxes and will likely clash with your home’s decor.

On the other hand, digital timers are much smaller and visually appealing. Digital timers have a much greater chance of complementing your home decor. The digital timer is automatic, and you can set it to a precise time and date. These devices usually have internal batteries to keep the internal clock and other workings powered even during an outage.

What to Watch Out for in an Extension Cord With a Timer

There are common problems that you may have with extension cords with built-in timers. Some of the issues are directly related to the extension cord, while others may be due to the timer malfunctioning.

Cord Damage

Inspect your extension cord to see if any wires are broken or if you notice any other damage along the length of the cord. There could also be tears in the insulation, which would lead to risks of electrical shock or malfunctions. If you purchase a cord that is too long, it can become a tripping hazard when not carefully set up.


One common problem you’ll see with a lengthy cord is overheating. Check if any spots are abnormally warm or hot using a thermometer gun.

Always select an extension cord with the correct rating for the load you want it to handle. Otherwise, you will be introducing a fire hazard into your home or workplace. 

Light Sensor

One issue you may encounter with your light sensor is that artificial light near your extension cord may cause the timer to think it’s daytime. This can cause your lights to cut off prematurely. If you have this problem, you may want to use a basic digital timer with your lighting setup.

How Do You Set a Timer on an Extension Cord?

The process depends on whether it is a mechanical timer or a digital timer switch.

How To Set a Digital Timer?

The process for setting a digital timer differs across devices and manufacturers. Usually, setting the current time and date, and programming the shutoff and turn-on times entails holding the “Set” button on the control panel. Please study the user manual for your product because the process described below is only a general guide.

Begin by allowing the timer to charge its internal battery (if equipped) for around 30 minutes.

Next, press and hold the ON button until the display comes on. Once your device has started, press and hold the “Clock” button and set the current time by pressing the “hour”, “minute”, and “day” buttons.

Program the specific time the outlet turns on by pressing the PRG button or its equivalent. “ON” will appear on the screen along with the program number. Just like setting the current time, use the proper button combination to set the exact time to turn on, and the day that the programmed timer setting will apply. Repeat this process for the “OFF” function.

How To Set a Mechanical Timer?

To set a mechanical timer, begin by turning the override switch (if equipped) to “Timer On”. Rotate the dial to the exact time of day you are currently at.

These timers feature pins spaced at 30-minute increments. When you press down on a pin, it turns the power on during that period.  Lift the pin to set the extension cord to cut the power off during that period.

For instance, if you want to set your device to cut the power off at 6 AM and turn it on at 6 PM, pull all the pins up between 6 AM and 6 PM. Leave all the other pins down.
