Cordless Heat Guns

Cordless drills, drivers, and vacuum cleaners are commonplace — but where are all the 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

The manufacturers who took on the challenge of building a user-friendly cordless heat gun had one main priority. This was to increase the efficiency by eliminating as much power dissipation as possible.

They achieved this through the following means:

Removing Extraneous Functions
Cord-free heat guns are back to basic units. There are no multifunction dials or LCD screens, which — although they increase usability — suck the battery juice. Temperature is typically controlled by one rocker switch.
Limiting Temperatures
The higher the temperature setting — the greater the draw on the power cell.

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.

Trigger Function
In an effort to conserve power, cordless hot air guns often feature trigger activation — meaning that the machine only emits heat while it is depressed. This prevents needless use and reduces battery drain. With a cabled unit, there is an on/off switch. Hence, even if you lay the gun down to take a break, the machine still produces hot air.

That said, some cordless guns have a ‘trigger-lock’ feature to keep the unit running continually — should you wish.

Snub Head Design
The head of a cordless heat gun is more compact than that of a standard mains unit. This reduces the distance that the internal fan has to push the hot air — meaning it requires less power.
Utilizing High-Performance Batteries
Gone are nickel-cadmium rechargeables. Instead, cordless hot air machines utilize more efficient and powerful lithium-ion cells. Furthermore, manufacturers such as DeWalt ensure that these batteries are compatible across their other products. Even if you already own a cordless DeWalt tool, you don’t need a multitude of different power packs.

Advantages of a Cordless Heat Gun

So, is a cable-free hot air machine right for you? Here are some benefits of ditching the mains lead.
Safety
Wielding a corded heat gun, especially with an additional extension cable, can be hazardous. Feet upon feet of power lead can cause trips and falls, or simply become tangled around your neck. Not an issue with cordless types.

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.

Compact Design
As mentioned above, a cordless heat gun typically has a snub-head design, to conserve energy. This compact build also allows you to reach into areas typically inaccessible by a standard size unit. Working under sinks or in car engine bays is possible with this tool.
Portability
With no cord, you can use your heat gun ‘out in the field,’ where there’s no access to a power outlet. This may appeal to those who will use their unit outside, or away from home.
Enhanced Freedom
Not being tethered to the wall enhances freedom and negates the requirements for extension cables. If you’re stripping a stair banister, a standard six-foot cord will be too short to reach an electrical socket at the top or bottom of the steps. However, a cordless model means that you don’t have to worry about running a four-gang.

Disadvantages of a Cordless Heat Gun

While cable-free hot air guns are remarkably versatile — they’re not suitable for everyone. Here are some of the downsides of dropping the power cord.

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.

Price

Cable-free machines can be tough on the wallet — often costing three times more than a mains-powered unit.

Lacking Power

It’s unusual for a cordless model to reach 1000 degrees Fahrenheit — standard on a cabled variety. Hence, if you’re trying to strip multiple layers of years’ old paint — a job that requires high temperatures — a cord-free machine may struggle,

Restricts Working Time

While lithium-ion batteries are powerful — they’re not miracle workers. Even on a low, 500-degree setting, you will struggle to achieve longer than 40 minutes of use on one charge.

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 Heat Guns Without Cables

While some of the rarest tools on the market — through some serious and extensive research, I’ve found what I consider to be the two most impressive cordless hot air machines available.
Our Rating: 4.7
Admittedly the cordless heat gun niche is limited — but this is perhaps the ultimate battery-powered hot air machine currently available.

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.
