An extension cord is extremely valuable for a range of purposes. If you own a generator, you would understand the value of a heavy-duty extension cord that can easily handle the power between the plugged devices and the generator. It is an invaluable tool that can be used for a range of applications. However, if you are looking for an extension cord that is mainly designed and built to connect with the generator, you must be vigilant while choosing one. As these cords have variable lengths, it lets you easily plug into the devices from anywhere. However, you must understand the top three most important parameters to check to decide the quality and ability of the extension cord. So let us find out what those are.
- Gauge: While buying the extension cord, from the numerous technical factors to check, the initial thing that you should definitely consider is the cord gauge. The thickness of the wire is mentioned as gauge which is measured in American wire gauge or AWG. You will mostly find AWG 8, AWG 10, and AWG 12 and so on. Remember that a higher gauge number means thinner wire, and a lower gauge number means thicker wire. A thick wire is built to handle immense power compared to a thin cord. So when it comes to choosing an extension cord for a generator, it is suggested to choose a lower gauge number and not to go more than 12 AWG.
- Length: There is no denying that we all buy extension cords because of the variable length it provides. It makes sure to remove all the limitations associated with distance. Nevertheless, you must know that longer cords mean more resistance. A cord with higher resistance can also result in a voltage drop. This can make the generator insufficient and hotter and easily damage other associated devices. It is recommended to stay with a length of 50 feet which is enough to run the cord into the house.
- Material: To ensure safety, you must check its material. Since a generator is often left exposed to weather changes, so is the extension cord; using a high-quality cord molded with PVC material can be a great addition. Therefore, always ensure that you read the manufacturer’s details in advance to ensure the material of an extension cord. Keep in mind to check the internal wire material; nothing can be better than copper wire.
While these are only a few important factors you must check while choosing an extension cord for a generator, you should also pay attention to several other important parameters. If you want to get a detailed guide to the buying factors, you need to keep reading. Later in the “Buying Guide”, we will provide all the critical parameters and technical aspects to check while choosing an extension cord for the generator. So, now let’s look at the top 10 Best extension cords available in the market for generators. We will provide detailed specifications to help you make it easy to buy one.

Buying Guide For The Best Extension Cord For Generator
From all the details provided about the best extension cords for generators, hopefully, it will become easier to make a choice now. Make sure that you read the specifications before you decide. However, if you’re not planning to buy an extension cord from this list, you must make sure to check all the important features of an extension cord that works with generators. Here are some of the main features that talk about the efficiency of a cord.
1. Gauge
While looking for an extension cord that works with your generator, the very first thing that you must consider is the gauge. The thickness of the extension cord gauge talks about the material’s safety. It is mainly mentioned as AWG or American wire gauze. Some of the most common numbers are 8, 10, 12, 14 and so on. Keep in mind that a higher gauge number means thinner wire, while a lower gauge number means thicker wire. A thicker wire has the capability of handling increased power compared to other thinner ones, and hence it is suggested not to go for thinner cords, especially when working with a generator.
2. Length
Depending on your requirement, it is better that you look for the length of the extension cord\. No denying that a better length is a great choice, but you must know that with greater lengths, it gets more resistance as well. A maximum of 50 feet is considered a good choice as it keeps a generator outside while not creating resistance and preventing the generator from damage.
3. Material
Don’t forget to check the quality of the material. By material quality, we mean that you must check that the interior wire quality is made with 100% copper and an external coating. Since the cord needs to stay outdoors, it must have resistance against different weather conditions like snow, sun, heat, rain, et cetera. A PVC material coating that has been effectively treated can be a good choice for longer use.
4. Safety Lock
Lastly, to ensure that there is no electricity loss or damage to the generator, you have to check that the extension cord has a safety lock system. Most of the cord has a twist lock system that keeps the cable in place and does not fall out. It not only makes sure of no wastage of electricity but also ensures no accidents.
FAQs:
You need to use a generator-specific extension cord due to its higher handling capacity of wattage and amperage than standard cords. So, these are considered for safe and reliable power delivery to appliances without causing overheating or damage.
A twist-lock plug is an electrical plug that uses twisting motion to connect or disconnect. They are designed to be durable, and weather-resistant and offer a secure connection to the generator and appliances with no more accidental disconnection. This type of plug is used in outdoor or high-vibration settings.
No, it is not recommended to use multiple extension cords, why because they will enhance the dropping chances of voltage and resistance. So, it’s ideal to use a single cord with an appropriate length and gauge but not a daisy chain system to extend the length.
Yes, the generator extension cords work well with all types of generators. But check and confirm that the cord’s amperage and plug type should match with the generator for their proper functioning. For more outlet specification details, we suggest you check the generator’s manual before purchasing the compatible extension cords.
Most generator cords have in-built power indicator lights at the plug ends. This is used to confirm that the cord is working properly and power flows through the cord. This feature is quite useful to troubleshoot any power-related issues.
Conclusion
Choosing the best generator extension cord depends on your power needs, length preferences, and durability. The Champion Power Equipment Generator Extension Cord is a top pick for overall performance and reliability. For a budget-friendly yet reliable option, the CircleCord Generator Extension Cord is a great choice. If you need a compact and durable cord, the Yodotek 1.5Ft Generator Cord stands out.
