Best Cordless Heat Gun
As an Amazon Associate we earn from qualifying purchases.
The best cordless heat gun for most readers is the one that runs on a battery they already own, so the listing is the place to start. This guide reads eight cordless heat gun listings from Amazon and reports only what each page states about battery status, maximum temperature, airflow and weight. Four are brand-name tools from DEWALT, Ryobi and Milwaukee, and four are third-party models that name a DEWALT or Milwaukee battery platform. Six listings say the battery is not included, and where two figures for one spec disagree, we show both.
Quick answer
- If you already own a DEWALT 20V MAX battery and charger, the tool-only DEWALT DCE530B is the brand-name match. Its listing says the battery and charger are sold separately.
- If you need a battery and charger in the box, the DEWALT DCE530P1 kit is the only listing that says it includes one, a DCB205 5.0Ah battery and charger.
- If you own Ryobi ONE+ or Milwaukee M18 batteries, the Ryobi listing says its battery and charger are not included, and the Milwaukee 2688-20 listing does not say whether they are.
- The highest stated maximum is 600℃ (1112℉) on the RIWELF Mode II setting. The LIVOWALNY and Synxiter listings give figures that conflict, and both are shown below.
The eight heat guns compared
The table uses only what each listing states, and a cell says not stated where a page is silent. Battery status comes first, because a tool-only listing needs a battery and charger you already own.
| Heat gun (listing) | Battery and charger | Maximum temperature | Airflow | Item weight |
|---|---|---|---|---|
| DEWALT 20V MAX DCE530B | Sold separately | 990 degrees F (532 degrees C) | 6.7CFM | 1.17 pounds |
| DEWALT 20V MAX kit DCE530P1 | Included: DCB205 5.0Ah battery and charger | 990 degrees F (532 degrees C) | 6.7CFM | 3 pounds |
| Ryobi ONE+ 18V (Tool Only) | Not included | 875 °F | not stated | 1.8 pounds |
| Milwaukee 2688-20 | not stated | not stated | not stated | 1.7 pounds |
| LIVOWALNY, DEWALT 20V compatible (Tool Only) | Not included | 550℃ (1022°F) in mode II; one bullet says 1202℉ (550℃) | 7CFM in one bullet; 9.9CFM in the description | 1.76 pounds |
| HILIPE, DeWALT 20V (No Battery) | Not included | 1022°F (550°C) | 7CFM | 1.7 pounds |
| RIWELF, Milwaukee M18 compatible (No Battery) | Not included | Mode II 50–600℃ (122–1112℉) | 50–250L/min | 1.32 pounds |
| Synxiter, DeWALT 20V (NO Battery) | Not included | 550℃ (1022°F) in mode II | 7CFM in one bullet; 120–200 L/min in another | 1.4 pounds |
Checking the temperature figures
Most listings give a maximum in both units. The formula F = C × 1.8 + 32 links them, so each pair can be checked on the stated figures alone. The check says nothing about output at the nozzle.
| Listing and setting | Celsius (listing) | Fahrenheit (listing) | Calculation | Result |
|---|---|---|---|---|
| DEWALT DCE530B and DCE530P1 | 532 | 990 | 532 × 1.8 + 32 | 989.6, rounded to 990: agrees |
| RIWELF, mode I | 300 | 572 | 300 × 1.8 + 32 | 572: agrees |
| RIWELF, mode II | 600 | 1112 | 600 × 1.8 + 32 | 1112: agrees |
| HILIPE, high | 550 | 1022 | 550 × 1.8 + 32 | 1022: agrees |
| Synxiter, mode II | 550 | 1022 | 550 × 1.8 + 32 | 1022: agrees |
| LIVOWALNY, mode II | 550 | 1022 | 550 × 1.8 + 32 | 1022: agrees; its 1202℉ bullet does not |
The DEWALT pair is the only case where rounding matters, since 532 degrees C converts to 989.6 degrees F. The LIVOWALNY bullet that reads 1202℉ (550℃) does not match its own Celsius figure, so this guide reports it as a conflict. Airflow is stated in CFM on five listings and in liters per minute on two, and this guide keeps each unit as written.
The eight heat guns, one by one
Each entry gives the listing’s stated figures and a line on when to skip it.
DEWALT 20V MAX Heat Gun, Tool Only (DCE530B)
The DCE530B is the tool-only version of DEWALT’s 20V MAX heat gun. The listing says it reaches up to 990 degrees F (532 degrees C), comes with two temperature settings, and has a lock-on button and a lock-off trigger for hands-free use. It also says up to 42 minutes of runtime per charge, but the footnote that explains that figure was not in the text we read.
| Spec | What the listing says |
|---|---|
| Battery and charger | Sold separately |
| Maximum output | Up to 990 degrees F/532 degrees C |
| Runtime | Up to 42 minutes of runtime per charge |
| Airflow | 6.7CFM |
| Controls | Lock-on button and lock-off trigger |
| Light | LED to brighten dark areas when the tool is in use |
| Included | Flat and hook nozzle attachments |
| Item weight | 1.17 pounds |
| Dimensions | 8.2 x 3.1 x 7.3 inches |
| Power | Battery powered, 20 volts |
| Warranty length | not stated; the page links to warranty information |
Skip it if you do not already own a DEWALT 20V MAX battery and charger, because the listing says both are sold separately. Skip it also if you need a runtime you can rely on from the listing alone, since that line depends on a footnote we did not read.
DEWALT 20V MAX Heat Gun Kit with Battery and Charger (DCE530P1)
The DCE530P1 is the kit version of the same heat gun. The title says battery and charger included, and the description names a DCB205 5.0Ah battery and charger. It repeats the 990 degree maximum, the 42 minute runtime line and the 6.7CFM airflow. Its listed weight is 3 pounds, against 1.17 pounds for the DCE530B.
| Spec | What the listing says |
|---|---|
| Battery and charger | Included: a DCB205 5.0Ah battery and charger |
| Maximum output | Up to 990 degrees Fahrenheit/ 532 degrees Celsius |
| Runtime | Up to 42 minutes of runtime per charge |
| Airflow | 6.7CFM |
| Controls | Lock-on button and lock-off trigger |
| Nozzles | Flat nozzle and hook nozzle attachment |
| Item weight | 3 pounds |
| Power source | Battery powered |
| Warranty length | not stated; the listing says a manufacturer warranty can be requested from customer service |
Skip it if you already have a DEWALT 20V MAX battery and charger, since the tool-only DCE530B covers that case. Skip it also if you need a light tool, because this kit weighs 3 pounds by its listing.
Ryobi ONE+ 18V Cordless Heat Gun (Tool Only)
The Ryobi listing describes the ONE+ 18V P3150 as a tool-only heat gun and says the battery and charger are not included. It gives a maximum of up to 875 °F for tasks such as shrink tubing, paint removal and thawing, and says the operating temperature is reached in under 10 seconds. The page gives no airflow figure and no warranty length.
| Spec | What the listing says |
|---|---|
| Battery and charger | Not included |
| Maximum temperature | Up to 875 °F |
| Time to operating temperature | Under 10 seconds |
| Nozzles | Deflector and concentrator nozzles |
| Item weight | 1.8 pounds |
| Material | ABS plastic |
| Airflow | not stated |
| Warranty length | not stated |
Skip it if you do not already own a Ryobi ONE+ 18V battery and charger, because the listing says neither is included. Skip it also if you need an airflow figure to compare against another tool, since this page gives none.
Milwaukee 2688-20 Cordless Heat Gun
The Milwaukee 2688-20 is a red compact heat gun. The listing says it is powered by an XC 5.0 battery and is compatible with all M18 red lithium battery packs. The listing text does not say whether a battery or charger is in the box, and it gives no maximum temperature or airflow figure.
| Spec | What the listing says |
|---|---|
| Battery and charger | not stated |
| Battery compatibility | All M18 red lithium battery packs |
| Time to operating temperature | 7 seconds |
| Maximum temperature | not stated |
| Airflow | not stated |
| Overall length | 6.4 inches |
| Dimensions | 2.5 by 6.4 by 8.3 inches |
| Item weight | 1.7 pounds |
| Features | Built-in LED light, guarded nozzle, ladder hook |
| Warranty length | not stated |
Skip it if you need a maximum temperature or airflow figure before you buy, because the listing gives neither. Skip it also if you do not already run M18 batteries, and confirm the battery line before ordering, since the text does not say whether one is included.
Cordless Heat Gun Compatible with DeWALT 20V (LIVOWALNY, Tool Only)
This tool-only model is sold by LIVOWALNY and described as compatible with the DEWALT 20V battery platform, with the battery not included. Its bullets give a heat-up time of 2-3 seconds, and runtimes of up to 6 minutes with a 2.0Ah battery, about 12 minutes with a 4.0Ah battery and approximately 15 minutes with a 5.0Ah battery. Its airflow is 7CFM in one place and 9.9CFM in another, and one bullet gives a maximum of 1202℉ that does not match its own 550℃.
| Spec | What the listing says |
|---|---|
| Battery and charger | Not included |
| Battery platform | DEWALT 20V (DCB203, DCB204, DCB205, DCB206 and more, as the listing states) |
| Modes | 300℃ (572°F) and 550℃ (1022°F) |
| Maximum temperature | 1202℉ (550℃) in one bullet; 1022°F in the mode line and title range |
| Heat-up | 2-3 seconds (bullet) |
| Airflow | 7CFM (bullet and flow field); 9.9CFM (description) |
| Nozzles | 5 |
| Wattage | 350 watts |
| Item weight | 1.76 pounds |
| Warranty | 2 Year Manufacturer (warranty field) |
Skip it if you need one airflow or maximum temperature figure to decide, since this page gives two of each. Skip it also if you want a DEWALT-branded tool, because the listing names LIVOWALNY as the manufacturer.
HILIPE Cordless Heat Gun for DeWALT 20V (No Battery)
HILIPE’s listing says the gun is tool only with no battery, and that it works with the DeWALT 20V max battery. It offers low and high temperature modes and says it can heat up to 1022°F (550°C) in 5 seconds. The bullets give a maximum air flow of 7CFM and five nozzles. The description also says the tool is adapted to DeWALT 18/20v batteries, while the product information lists 20 volts, so the voltage line deserves a check before you order.
| Spec | What the listing says |
|---|---|
| Battery | Tool only, no battery |
| Battery platform | DeWALT 20V max (bullet); DeWALT 18/20v (description) |
| Temperature | Up to 1022°F (550°C) in 5 seconds (bullet) |
| Airflow | Max air flow of 7CFM |
| Nozzles | 5 |
| Lock | Lock-on button |
| Voltage and wattage | 20 volts; 350 watts (product information) |
| Item weight | 1.7 pounds |
| Warranty length | not stated |
Skip it if you need the battery in the box, because the listing says there is none. Skip it also if you want a DEWALT-branded tool, since the listing names HILIPE as the brand.
RIWELF Cordless Heat Gun Compatible with Milwaukee M18 (No Battery)
RIWELF’s listing describes a tool-only heat gun that works with Milwaukee M18 batteries, and says it is not an official Milwaukee product. It has two temperature modes, 50 to 300℃ (122 to 572℉) and 50 to 600℃ (122 to 1112℉), an LCD screen for temperature and airflow, a switch lock for hands-free use and a memory function that keeps the last settings. The listing says its products carry a 1-year quality warranty.
| Spec | What the listing says |
|---|---|
| Battery and charger | Tool only; battery sold separately |
| Battery platform | Milwaukee M18 (18V battery series) |
| Modes | Mode I 50–300℃ (122–572℉); Mode II 50–600℃ (122–1112℉) |
| Airflow | Adjustable from 50–250L/min |
| Features | LCD display, switch lock, memory function, 6-second cool-down |
| Nozzles | 4 |
| Voltage and wattage | 18 volts; 350 watts |
| Item weight | 1.32 pounds |
| Power source field | ac, while the bullets describe a battery tool |
| Warranty | 1-year quality warranty (bullet) |
Skip it if you want a DEWALT or Ryobi battery, because the listing names only the Milwaukee M18 series. Skip it also if the power source field matters to you, since it says ac while the bullets describe a battery tool, and the listing does not resolve that.
Synxiter Cordless Heat Gun for DeWALT 20V (NO Battery)
Synxiter’s listing describes a tool-only heat gun for DeWALT 20V batteries and says it does not contain any batteries. It gives two modes, 300℃ (572°F) and 550℃ (1022°F), and states airflow both as a 7CFM maximum and as an adjustable range of 120 to 200 L/min. The listing says the power cuts off when the voltage is lower than 14v, and its tips say to be careful when using the heat shrink gun to avoid burns.
| Spec | What the listing says |
|---|---|
| Battery | Not included |
| Battery platform | DeWALT 20V; the tips name DCB206, DCB205, DCB204, DCB181, DCB182, DCB200 and DCB203, and more |
| Modes | 300℃ (572°F) and 550℃ (1022°F) |
| Airflow | 7CFM maximum (bullet); 120–200 L/min adjustable (bullet) |
| Wattage | 400W in the title and a bullet; 350 watts in the product information |
| Display and cut-off | LED display for temperature and voltage readings; power cuts off below 14v |
| Nozzles and accessories | 4 nozzles and a scraper |
| Item weight | 1.4 pounds |
| Warranty | 12 months of product quality service (bullet) |
Skip it if wattage decides your purchase, since the title says 400W and the product information says 350 watts. Skip it also if you need a single airflow figure to compare, because the bullets give two.
How we chose
We started from the Amazon search for best cordless heat gun and read the listings on 2026-10-22. The search reported more than 2,000 results, and we read the first results page. That page showed cordless heat guns from brand-name makers and from third-party sellers, along with corded heat guns and a butane model. We left out the corded and butane models because they are not cordless heat guns.
The criteria were three. First, the listing had to describe a cordless, battery-powered heat gun. Second, the set had to cover both brand-name tools and third-party models, so readers with different batteries can compare. Third, each listing had to name the battery it runs on, so every row of the table has a battery line. We read eight listings and did not rank them. Where a listing gives two figures for one spec, both appear.
What we could not verify
- Real heat output at the nozzle. This guide does not check it. Every temperature and airflow figure here is what a listing states.
- The runtime lines. The DEWALT pages state up to 42 minutes per charge, and the footnote that sets the conditions was not in the text we read. The LIVOWALNY page gives runtimes for three battery sizes, and this guide does not check them.
- Battery fit for the third-party tools. Four listings say their heat gun works with a named battery platform, and the guide does not confirm that any battery fits any tool.
- Whether the Milwaukee 2688-20 comes with a battery and charger, since its listing text does not say.
- Which figure is right where a listing gives two, such as the LIVOWALNY airflow and the Synxiter wattage.
What the sources do not say
- Whether a battery or charger is included with the Milwaukee 2688-20, or what its maximum temperature is.
- An airflow figure for the Ryobi ONE+ tool, and a warranty length for the DEWALT, Ryobi, Milwaukee and HILIPE tools. The LIVOWALNY page names a 2 Year Manufacturer warranty, the RIWELF page a 1-year quality warranty, and the Synxiter page 12 months of product quality service.
- Any certification mark. None of the eight captured listings names one.
- How any of these tools compares with a corded heat gun on output. The DEWALT DCE530B page says its tool goes places a corded heat gun cannot, which is a claim without a figure.
FAQ
Does a cordless heat gun come with a battery?
Most of these listings do not. The DEWALT DCE530B, the Ryobi tool, and the LIVOWALNY, HILIPE, RIWELF and Synxiter tools all say the battery is not included. The DEWALT DCE530P1 kit is the only listing that includes a battery and charger, a DCB205 5.0Ah battery. The Milwaukee 2688-20 listing does not say either way.
Which battery platforms do these heat guns name?
The DEWALT 20V MAX platform appears in the DCE530B, the DCE530P1 kit, and the LIVOWALNY, HILIPE and Synxiter listings. Ryobi ONE+ 18V is named for the Ryobi tool, and Milwaukee M18 for the Milwaukee 2688-20 and the RIWELF tool. For the DEWALT pack side of the choice, see our guide to DEWALT battery choices for a leaf blower, and for how voltage is listed on lawn and garden tools, see lawn and garden battery voltage.
What is the highest maximum temperature among these listings?
The highest figure is the RIWELF Mode II setting, 50 to 600℃ (122 to 1112℉). The two DEWALT listings state up to 990 degrees F (532 degrees C), and the LIVOWALNY, HILIPE and Synxiter listings state 550℃ (1022°F). The Ryobi listing states up to 875 °F, and the Milwaukee listing gives no maximum figure.
Why do some listings give two airflow figures?
The LIVOWALNY listing gives 7CFM in its bullet and flow field, and 9.9CFM in its description. The Synxiter listing gives a 7CFM maximum in one bullet and an adjustable 120 to 200 L/min in another. The listings do not explain the gap, so this guide shows each figure as written and does not pick one.
Is the DEWALT kit or the tool-only model the better choice?
If you already have a DEWALT 20V MAX battery and charger, the tool-only DCE530B matches that case. If you do not, the DCE530P1 kit is the only listing that includes both. The two DEWALT listings state the same maximum temperature, runtime and airflow figures, so the choice comes down to what you already own.
What should I check on a third-party listing before I order?
Check the battery line, the maximum temperature, the airflow figure and the warranty line. Several third-party listings disagree with themselves: LIVOWALNY on airflow and maximum temperature, Synxiter on wattage, RIWELF on power source, and HILIPE on battery voltage.
Bottom line
Choose the heat gun whose listing names the battery you already own, and buy a tool-only model only if you already have that battery and charger. If you have no battery yet, the DEWALT DCE530P1 is the one listing here that includes one.
