Best extension cord for the treadmill: Buying Guide

How to pick the best extension cord for treadmill

Once in a while, an extension cord is something you really need for the convenient and safe use of your home appliance.

And when you are looking for an extension cord for a treadmill then some factors are important to look at. Let’s see those factors…

Power Rating

A treadmill is an electrical machine that requires a moderate level of smooth power supply. So if you want to keep your treadmill safe an extension cord with high amp, volt, and watt is required.

An extension cord that can support from 13 Amp up to 15 Amp would be good. While a voltage level of 125 is optimum for treadmill connection. 

Wire Gauge

The wire gauge is available in different level thicknesses. You can get the idea of whether an extension cord is heavy-duty or not. The treadmill would require a good amount of electricity continuously for at least 25-30 minutes. 

Let me make it clear to you. A higher gauge number means the cord is less thick and a lower gauge number means the high thickness of the cord. For your powerful treadmill machine, you should buy a 14-16 AWG extension cord. 

Length of the cord

You might think that the longer the extension cord the better it is. While in reality, the too-long cord has shortcomings. Longer cords have to lack in handling high current compared to the same gauge shorter cord. 

Keeping this in mind, you should buy something that can range from 6ft.- 10 ft. extension cord for a treadmill connection.

Plugging System

Both two-prong and three-prong extension cords you can buy for the treadmill. But between these two three-prongs can ensure more safety which reduces the chances of any fire issues. 

Make sure before buying that the plug and connector have well-built quality. High-quality connectors will not give you a hard time during a connection. 


Any electrical product carries potential danger during use. And when you see a product was given clearance by a related authority like UL listing and ETL listing then you can use it as a reliable extension cord. Never buy an extension cord that isn’t UL or ETL listed. 

Which is the better 14 or 16 gauge extension cord for a treadmill?

As a lower gauge means more thickness so 14 gauge will be better than 16 gauge cord as it will be safer to use for your treadmill. But a 16 gauge will also do the job. 


Now you as a user know that a good one does cost more so my advice for you is to go for the expensive one that has a lower gauge with a high power rating. 

I hope you will be able to select and use the best extension for the treadmill after going through all the cords. Stay safe!
