Corded Heat Guns vs Cordless Heat Guns 

Though the purpose of using a heat gun is the same, the same device being corded and cordless makes them suitable for versatile jobs. Both of them have their benefits and drawbacks. Thus, it's important to know the differences so that you can understand whether you need corded or battery operated heat guns.

Cordless heat guns

Cordless heat guns are handy, portable, and easy to use anywhere. You don't need to look for an available electric connection and worry about cord length. If you are working on outdoor projects, then it's one of the essential tools you need.

Though portable heat guns tend to have weak power and airflow compared to corded ones, they are a helping hand during any emergency. However, if you need a more powerful one, then the price will also get higher. Nevertheless, they are super lightweight and small in size, so it's easy to carry and use for small spaces without getting your hands numb.

Considering all the features and advantages, a cordless heat gun is time-saving and quick to use for outside or DIY needs. Thus, it's a popular choice for DIY users and professionals that work on outdoor projects. You can use it anywhere regardless of having a power outlet nearby.

Corded heat guns

Corded heat guns don't come with a battery. Compared to the cordless heat guns, they are quite cheap. So you don't need to worry about its run time or the necessity of recharging it. All you need is an electric power source.

Since the corded heat guns have more power and airflow, they make any job complete quickly and efficiently. However, using a corded gun limit your access to use it anywhere else. Every time you use it, you need to have a continuous electric connection, proper airflow, a long cord, and some other features.

Also, corded heat guns are big, thus heavyweight. Using the device for a long time can cause fatigue. If you are a professional user and work on large projects, then corded heat guns would be ideal for your project.

Battery Powered Heat Gun

How to Choose the Best Cordless Heat Gun? 

Whether you purchase a small cordless heat gun or an automotive heat gun, if you aim to go for a good quality cordless one, you need to pay attention to certain features. These features will help you understand how you want the heat gun to be. Thus, you can also set a fair budget to make the best investment of your money on the right tool.


The battery is the most important part of a cordless heat gun. The capacity of the battery will decide the power and duration of the device. If the device has a high wattage capacity, you will get a higher temperature and airflow.

If you need the gun for occasional use, then you can go for a mini cordless heat gun with average battery power. However, if your project requires frequent use, then a portable heat gun cordless with lithium-ion 5AH or 6AH will have a run time of up to 30 minutes.

Heating time 

Usually, rechargeable heat guns get quickly heated up. Most good quality guns take only 10 seconds or so to warm up which is enough for small work. But, for major tasks, the device needs to have sufficient heat which may take a while. And, there are heat guns that have adjustable heat settings.

Temperature control

For small projects or occasional use, the heat gun with fixed temperature and fan speed is convenient and safe to use. However, if you need the device to use more than paint stripping or shrinking plastic, then it would be better if the device has a temperature control setting.


Whether you are dealing with corded or battery heat guns, safety is a must feature the device need to have. In terms of a cordless heat gun, it deals with high heat and battery. Both of them have a high-risk factor of causing accidents and damage to the user as well as the projects.

Thus, heat guns must come with overload protection. Such features automatically turn off the device when the temperature is too high to overheat the device. Thus, you must look for thermal cut-out or automatic shut-off as a safety measure for any cordless heat gun.

Ergonomic design

Cordless heat guns are quite handy and lightweight. Thus, they are easy to use and don't cause fatigue. However, having the device designed in an ergonomic style is also important. When you are checking a heat gun, pay attention to its weight, grip, size, ease of use, and other user-friendly features.


Since the heat gun will be hand-operated, it needs to have a durable construction. Thus, check whether your chosen heat gun has a sturdy frame considering the power capacity. Every part should be made with durable material.


Compared to corded heat guns, cordless guns are expensive. Thus, you need to be careful about setting the budget how much it should cost to find the best budget heat gun. Considering the features and performance, a top-quality heat gun can cost $70 - $200.
