The Best Cordless Heat Guns — Buyers Guide, Review and ComparisonCompact and cable-free, cordless heat guns deliver greater operational freedom and portability than their mains-powered counterparts. While remarkably rare in the hot air niche, a few high-end manufacturers have taken up the mantle to produce machines that run off long-lasting and powerful lithium-ion cells. And, although they lack some of the tailorable functions of AC hot air guns in order to save energy — some DC units offer dual temperature control and feature LED lamp illumination.

Cordless Heat Guns
Seeking out one of these elusive power tools is more challenging than locating the lost city of Atlantis. It’s as if all the manufacturers as an entire group have forgotten to include these machines in their product lines.
However, battery-powered heat guns are available — if you know where to look.
Sit back, while I reveal why these units are so sparse online and on DIY store shelves — and explain how you can get hold of one of these remarkable machines.
Why Are There So Few Heat Guns Without Cords?
Cordless power tools are nothing new.
It was nearly sixty years ago, in 1961, that Black and Decker introduced the first major cable-free machine, the No.725 drill. Since that time, cordless tools have become commonplace — from vacuum cleaners through to nail guns. Yet, there are very few heat guns with this feature.
The reasons for this are efficiency and practicality.
A typical corded hot air machine is a 1500-watt unit, delivering over 1000 degrees Fahrenheit of heat, and running at around 13 amps.
That, buddy, is a lot of power.
Firstly, this means you need one seriously hefty cell to run the heat gun. And, the larger the battery pack, the heavier the machine and the more difficult it is to wield. A cordless feature is supposed to make use more comfortable and straightforward — not require you to have forearms like Schwarzenegger.
Secondly — despite modern technological advancements — by their very nature, cable-free heat guns are rather inefficient.
Take your cordless drill as an example. This machine turns chemical energy (in the battery) into mechanical energy (driving the motor and subsequently the drill bit). This results in low power wastage — and once you’ve finished drilling, the draw on the battery ceases.
Hot air guns, however, spend energy like a beast.
Turning chemical energy into heat is wasteful. Ok, you may be warming up paint ready for stripping — but much of the heat is absorbed into the gun shell, nozzle, and dissipated into the air around your working material. This creates a massive draw on the cell — running it down quickly. This is the reason why your house has central heating — and isn’t warmed by an electric heater that runs off a few AAA batteries.
Hence, the majority of DIY brands took the view that a cordless heat gun was neither practical nor efficient enough for the market. Yet, there were some maverick renegade companies who refused to accept this situation — and looked for methods to create a cable-free machine.
Features of a Cordless Hot Air Blower
They achieved this through the following means:
Removing Extraneous Functions
Hence, a typical battery powered heat gun will have a maximum level lower than 1000 degrees Fahrenheit. Furthermore — as the manufacturer has reduced the number of functions — these machines only have one or two heat settings. Some mains-cable varieties have a plethora of options.
That said, some cordless guns have a ‘trigger-lock’ feature to keep the unit running continually — should you wish.
Snub Head Design
Utilizing High-Performance Batteries
Advantages of a Cordless Heat Gun
Furthermore, the trigger feature of a cordless hot air gun means that the unit will cease to produce heat when you lay it down. Conversely, a cable-powered unit could cause accidental burns to furniture or drapes if you forget to switch off after use.
Disadvantages of a Cordless Heat Gun
Lack of Temperature Choice
As cordless hot air guns only have one or two temperature settings, this can restrict their number of applications — especially in the lower heat range. This makes them unsuitable for projects like removing screens from smartphones or vinyl floor lifting.
Furthermore, for those DIYers who require precise control — they lack the ability to make small temperature adjustments. If that’s what you need, I’d suggest checking out digital heat guns instead.
Restricts Working Time
Admittedly, if you’re on a small project, such as melting glue, this may not be an issue. However, tackling a more extensive job, such as stripping your living room baseboards, is a different ball game. You will need to take frequent breaks to allow your battery to recharge — or alternatively purchase additional power cells.
The Best Battery Powered Heat Guns
It’s fuelled by a 20-volt lithium-ion cell that’s compatible across the DeWalt cordless power tool range. So, if you have a drill or driver from this manufacturer — you already have a backup battery.
Unlike the majority of other cable-free units which only offer a single temperature setting, this machine has two — 500 or 990 degrees Fahrenheit. Thus making it ideal for paint stripping, car wrapping, Spackle drying, and glue removing.
Particularly noteworthy is the inclusion of an LED lamp in the gun head. This can provide welcome illumination when working in lofts, under floorboards, or in car engine bays.
While the battery should last for around 42 minutes on a single charge — you still want to ensure that it’s not used unnecessarily. Hence, it’s pleasing to see that this heat gun is activated by a trigger — release, and the heat ceases — ensuring that you don’t leave the unit on and waste vital juice.
- A choice of either 500 or 990 degrees Fahrenheit.
- Trigger lock function.
- Compact design allows access into confined spaces.
- Delivers 6.7 CFM.

Although rarer than an accountant with personality — cordless hot air machines can increase your working freedom.
These innovative units free you from the shackles of mains cable tethering. They allow you to complete projects without tripping over cables and enable you to access harder to reach areas.
Admittedly, the lack of temperature choice can restrict their application flexibility, If this is important, you should consider a digital unit instead. Furthermore, being powered by a battery, your working times are restricted. If that’s an issue, think about a corded dual temp gun.
However, if you want to own the Holy Grail of hot air tools — check out the two cordless heat guns above.
Cordless Hot Air Gun FAQs
Q: What Is Better — Cordless Heat Gun vs Corded Heat Gun?
It depends on your requirements. Cordless units increase safety, allow you to work in confined areas, and enable you to complete projects away from power sources.
Corded guns have a wider choice of temperatures and a higher upper heat level. They ensure you can finish your job without having to wait for a battery to recharge.
Q: Will Dewalt Make a Cordless Heat Gun?
They already do! One of their latest hot air machine models is the DeWalt DCE530B. This is a dual temperature cordless heat gun that comes complete with two nozzle attachments. To check out this impressive unit, take a look here.
Q: How Hot Does A Cordless Heat Gun Get?
While not achieving such high temperatures as a mains-powered unit, a cordless hot air machine will typically reach around 900 degrees Fahrenheit.
Q: Is a Cordless Hot Air Gun Expensive?
Cable-free heat guns are somewhat harder on the pocket than their corded counterparts. However, examples such as the DeWalt DCE530B remain affordable and come with the backing and experience of a major industry player. To check out the current cost of the Cordless Heat Guns.
Q: Why Are There No Cordless Heat Guns?
The energy demands of a heat gun make it challenging for manufacturers to design such models. They need sufficient battery power to warm the heating coil, while keeping the overall weight low.
However, some brands have circumvented these issues by making cordless guns with restricted temperatures. They have a more compact design, and incorporate a power-saving trigger function.
Q: How Long Does the Battery Last on a Cordless Heat Gun?
One charge of a standard 20-volt lithium-ion battery typically delivers around 40 minutes of continuous hot air gun use.
