Adequate heating isn’t always possible, primarily if you work outdoors or in places like workshops or garages that don’t have heating systems or much insulation. That’s when a cordless heater can be your best friend, and happily, they’re very affordable.
The best cordless heaters are reliable, easy to set up and provide enough heat output to warm up a small-to-medium-sized area. Whether you want to warm your hands and feet while working outdoors during the winter or make a chilly indoor area feel more comfortable, a cordless heater is all you need to stay toasty. They’re also good to have on hand in case your home ever loses power in the winter.
We researched options from a range of brands and found the DeWalt DXH12B to be the best option for just about any situation and can cover a 1,700-square-foot area.
Which cordless heaters are best?
DeWalt DXH12B
Best of the Best
Heating Capacity: 12,000 Btu | Portability: Yes | Run Time: 13 hr | Noise Level: NA | Power Source: DeWalt 20-Volt MAX, FlexVolt batteries
The DeWalt DXH12B (F332000) is one of the best cordless heaters. It runs on propane and offers 12,000 Btu plus a powerful high-speed fan, which means it can blow enough warm air to heat a 1,700-square-foot area.
Its durable exterior allows it to withstand harsh climate conditions, making it a top choice for outdoor workers who need to stay warm when the temperature is low. Its rugged build and handle make it easy to transport and protect against dirt, debris and other work hazards. And the powerful LED light bar is a terrific feature for graveyard-shift workers.
We were also impressed by its run time. On a 1-pound propane cylinder, it can last approximately 13 hours, which is more than enough time for most people’s needs. There are three heat settings, and for extra convenience, it has three USB ports to charge devices.
In addition to the features above, customers really love this heater for its built-in safety sensors. It has tip-over shutoff and an oxygen-depletion sensor, so it’s safe for indoor use. Plus, its ability to be powered by DeWalt 20-Volt MAX and FlexVolt batteries makes it truly portable.
Ontel Handy Heater Freedom Wearable Neck Heater
Best Bang for the Buck
Heating Capacity: NA | Portability: Yes | Run Time: 6 hr | Power Source: USB rechargeable battery
The best thing about the Ontel Handy Heater Freedom Wearable Neck Heater is how practical it is for everyday use. Unlike bulkier cordless heaters, this handy gadget conveniently wraps around your neck without limiting mobility, making it suitable for working outdoors, walking your dog or staying comfortable in a chilly office building or workshop.
It boasts four heat settings so you can adjust the temperature based on your preference. (Note that some users found the highest setting to be hot enough to cause minor burns after a short time, so it’s best to put it over a shirt or towel instead of directly on the skin.)
Extremely quiet, it’s easy to forget you’re even wearing it. And because the rechargeable battery can last up to six hours on a full charge (depending on the setting you choose), it should provide you with ample heat for any activity.
If all you need is a personal warmer, this is a fantastic choice. It’s incredibly lightweight, affordable and comfortable to wear underneath your winter jacket to warm your shoulders and upper body.
DeWalt DXH70CFAV
Best for Outdoor Workers
Heating Capacity: 68,000 Btu | Portability: Yes | Run Time: 13 hr | Power Source: 20V Max, FlexVolt Batteries

Remington 60,000 Btu Heater
Functional and Versatile
Heating Capacity: 60,000 Btu | Portability: Yes | Run Time: 10.5 hr | Power Source: Battery, AC Power

Not intended for indoor use, it also features a five-point safety system. This includes a heat sensor safety label indicator to show when it’s too hot to touch. Overall, it’s a versatile choice for outdoor workers and, best of all, it’s reasonably priced for what you get.
Master MH-60VBOA-GFA Propane LP Portable Heater
Durable and Rugged
Heating Capacity: 60,000 Btu | Portability: Yes | Run Time: 10.5 hr | Power Source: Battery, AC Power
The Master MH-60VBOA-GFA is made of durable steel and has a reliable ignition system that works under any temperature conditions. Even if it’s windy, this cordless heater keeps running and can adequately heat areas as large as 1,500 square feet.

This cordless heater is a customer favorite that delivers on all fronts. It’s highly durable, works well in harsh weather conditions and offers variable Btu output. Plus, thanks to the top handle, it’s easy to set up and transport.
DeWalt 20-Volt Max 90,000 Btu Heater
High Heat Output
Heating Capacity: 90,000 Btu | Portability: Yes | Run Time: 6 hr | Power Source: Batteries, AC Power
The DeWalt 20-Volt MAX Heater is not only one of the most robust cordless heaters, but it’s also one of the most expensive. However, there are plenty of good reasons for its high cost, and if you want a reliable unit, it’s absolutely worth your consideration.
For starters, it’s a forced-air kerosene heater, which heats more efficiently than propane options, saving you money in the long run. The heating system generates up to 90,000 Btu, quickly and effectively warming areas as large as 1,750 square feet. And if you don’t have the required DeWalt 20-Volt Max or 60 Flexvolt batteries handy, you can use a corded power source instead.
When it comes to safety, DeWalt thought of everything. There’s an emergency battery system, which allows the unit to complete a cooling cycle even if the power source is removed.
Plus, the internal system monitors the fan motor and combustion performance for optimal safety conditions. It’s one of the best choices for those who want maximum heat output in outdoor environments.
Remington Heat Hog HOGREM-80TBOA-KFA-B
Most Value
Heating Capacity: 80,000 Btu | Portability: Yes | Run Time: 9 hr | Power Source: Battery, AC Power
The Remington Heat Hog offers similar performance to the DeWalt 20V Max 90,000 Btu Heater but is about $100 cheaper, making it a bargain pick by comparison. It can be powered by various fuel sources, including kerosene and diesel, and is duo-power compatible, meaning an electrical cord or batteries can power it.
It boasts an impressive 80,000 Btu heat output for heating areas up to 2,000 square feet. It also offers variable temperature control and requires minimal maintenance. It’s compatible with many batteries, including those by top tool manufacturers such as DeWalt and MasterForce, and the durable steel construction makes it perfect for outdoor working conditions, such as construction sites.
Compared to the DeWalt 20-Volt Max above, it doesn’t have the same safety features or Btu output. But this Remington Heat Hog cordless heater can provide adequate heat to a larger indoor or outdoor area. It’s a solid choice for those who want to stay warm while working outside and easily control heat output.
How we analyzed
We researched various cordless heaters and compared specs, performance and customer reviews to determine which models are the best. From there, we compiled a list featuring seven of the best cordless heaters based on heat capacity, zone coverage and battery life. In addition, we looked at whether the price was fair and if the company had any negative reviews regarding its customer service.
Key features to consider
Power source
Battery-powered
All cordless heaters are battery-powered, and some have dual-power-source compatibility, which allows you to power them with an electrical cord. Battery compatibility is what makes cordless heaters portable. However, heat output may be limited when using a battery power source rather than a direct corded power source or a fuel-powered heater. Also, batteries eventually drain, meaning if you don’t have a backup, you might be out of luck.
Propane-fueled
Most cordless heaters use propane canisters as fuel. It’’s a highly efficient source of fuel that offers higher heating power and longer operation time. However, propane-fueled cordless heaters should only be used outdoors or in well-ventilated areas for safety.
Rechargeable heater
Rechargeable heaters are highly convenient. Many are equipped with a rechargeable lithium-ion battery, so you can simply charge the battery when it runs out. They’re eco-friendly, cost-effective and portable. However, it takes time to charge batteries, so you may be stuck without heat for a while as you wait for it to charge fully.
Our top picks: Power source
- DeWalt DXH12B Cordless Propane Heater, DeWalt DXH70CFAV Battery-Start Cordless Propane Heater, Remington LP Propane Forced Air Heater with Electric Start and Master MH-60VBOA-GFA Propane LP Portable Heater: These heaters are primarily designed for use with propane tanks, but they can also be powered electrically with batteries or power cords.
- Ontel Handy Heater Freedom: This personal neck heater has a rechargeable lithium battery that can be charged with a USB cable.
Heating capacity
Measured in Btu
Heating capacity is typically expressed in British thermal units (Btu). A higher Btu rating indicates greater heat output. To heat a small area of less than 100 square feet, look for a heater with 3,000 to 5,000 Btu. Medium spaces of 100 to 200 square feet require a higher Btu output of 5,000 to 9,000, while larger outdoor areas or open spaces require something more robust, typically a unit with 10,000-plus Btu.
Adjustable heat settings
A power on-off switch makes an appliance easy to operate, but to adjust warmth based on your preference or comfort level, you’ll want a heater with adjustable or variable heat temperature control. Most units have a dial or a button to adjust heat output.
Our top picks: Heating capacity
- DeWalt DXH12B Cordless Propane Heater: This heater has only a 12,000 Btu heat output, but it can heat a large area of up to 1,700 square feet.
- Ontel Handy Heater Freedom: This heater doesn’t have a Btu spec because of its small size and personal design.
- DeWalt DXH70CFAV Battery-Start Cordless Propane Heater: Its robust 68,000 Btu makes it a top choice for outdoor workers.
- Remington LP Propane Forced Air Heater with Electric Start and Master MH-60VBOA-GFA Propane LP Portable Heater: These heaters offer similar heat output with 60,000 Btu, which is sufficient to warm areas as large as 1,500 square feet.
Portability
Compact design
Cordless heaters are designed primarily for portability. Manufacturers make them lightweight and compact so they’re easy to carry around. Plus, most compact heaters have a durable handle.
Weight
Consider the weight of the heater, especially if you plan to use it for camping, hiking or outdoor work. Aside from personal heaters that you wear on your body, which weigh just a few pounds, most cordless heaters do not exceed 15 pounds.
Fuel/battery portability
If the heater uses external fuel canisters or batteries, ensure they’re easy to carry and replace during extended use. Fuel canisters designed for use with cordless heaters are compact and batteries are small enough to pack in a toolbox, backpack or other small containers.
Our top picks: Portability
- DeWalt DXH12B Cordless Propane Heater: It’s one of the bulkier cordless heaters, but it has a durable handle for easy transportation.
- Ontel Handy Heater Freedom: You can wear it around your neck under virtually any circumstances without mobility restriction.
- DeWalt DXH70CFAV Battery-Start Cordless Propane Heater, Remington LP Propane Forced Air Heater with Electric Start and Master MH-60VBOA-GFA Propane LP Portable Heater: All three heaters have a similar cylinder design, an ergonomic handle and a lightweight but durable build for portable convenience.
Safety features
Tip-over protection
A heater can potentially cause a fire if it’s left running too long or unattended. However, many models have tip-over protection, which helps mitigate this possibility. This feature automatically shuts off the heater if it tips over.
Overheat protection
Another safety measure to ensure your cordless heater offers is overheat protection, which prevents the heater from operating if internal components become too hot, ensuring safety and durability.
Oxygen-depletion sensor (ODS)
A cordless heater running indoors may deplete oxygen levels, so it’s crucial to have a unit with an oxygen-depletion sensor if you plan on using a fuel-powered heater indoors. This sensor shuts off the heater if oxygen levels drop too low.
Flame guard
For propane models, a flame guard provides added safety by shielding the flame from external interference. It also helps protect you from accidentally touching the heat source, which can cause painful burns.
Our top picks: Safety features
- DeWalt DXH12B Cordless Propane Heater: This propane heater is safe for indoor use and has tip-over protection and an ODS.
- Ontel Handy Heater Freedom: It doesn’t have any safety features, but it doesn’t really need any because it’s a small, personal warmer. However, some customers reported that it can get too hot on the highest setting and cause minor burns if placed directly on the skin for too long.
- DeWalt DXH70CFAV Battery-Start Cordless Propane Heater: The high-temperature switch limits heat output for added safety.
- Remington LP Propane Forced Air Heater with Electric Start: This heater has a high-temperature-limit shut off, flame-out fuel cut and a thermocouple.
- Master MH-60VBOA-GFA Propane LP Portable Heater: This propane-fueled heater’s most notable safety feature is continuous electronic ignition, which prevents unexpected shutdowns.
Run time
Battery life
Battery-powered models are highly convenient, but they must be able to provide several hours of heating. Most cordless heaters offer a minimum of four to six hours of heat output, but on lower heat settings, some models can last well over 10 hours.
Fuel efficiency
For fuel-powered heaters, look for models with efficient fuel consumption that can last several hours on a single canister. You typically won’t have to worry about this with most fuel-powered heaters as they’re designed to run on propane, kerosene or diesel, which are all highly efficient and can last a long time.
Recharge time
If the heater uses rechargeable batteries, check how long it takes to recharge fully and whether you can use the heater while charging. Fortunately, many tool batteries, such as the DeWalt 20V Max, can fully charge in just 90 minutes. Ultimately, it depends on the size and capacity of the battery.
Our top picks: Run time
- DeWalt DXH12B Cordless Propane Heater and DeWalt DXH70CFAV Battery-Start Cordless Propane Heater: DeWalt’s top cordless heaters boast impressive battery life at a whopping 13 hours on a full charge.
- Ontel Handy Heater Freedom: Because it’s a smaller personal warmer, the battery life lasts six hours.
- Remington LP Propane Forced Air Heater with Electric Start and Master MH-60VBOA-GFA Propane LP Portable Heater: Both of these units can last up to 10.5 hours on a full charge, but the duration depends mainly on the heat setting.
