The best portable gas heater for camping depends on where you plan to use it, how much heat you need, and whether you want propane or another fuel. The Mr. Heater Portable Buddy is a practical choice for adjustable radiant heat, while the Big Buddy offers higher stated output for larger areas. Two compact propane models suit outdoor activities, and the diesel heater is an alternative for campers specifically seeking diesel-powered heat. Always follow the heater’s instructions and never use a fuel-burning heater in an enclosed space unless the manufacturer explicitly approves that use.

Mr. Heater Portable Buddy
The Mr. Heater Portable Buddy provides two listed heat outputs: 4,000 and 9,000 BTU per hour. Its radiant heat is specified for areas up to approximately 225 square feet. The product is described as designed and approved for indoor and outdoor use, a distinction that makes it more versatile than heaters described only for outdoor settings.
Best for: Campers who want a portable propane heater with a lower setting for milder conditions and a higher setting when more warmth is needed. It was selected for its stated output, coverage information, and indoor/outdoor approval.
Limitation: Its stated coverage is smaller than the Big Buddy’s. Indoor approval does not mean it is suitable for every enclosed camping space. Follow the specific manual’s placement, ventilation, and operating instructions.
Portable Propane Heater With Two Settings
This compact propane heater is described for outdoor heating, including camping, hunting, tailgating, and ice fishing. Its features list radiant heat for up to 200 square feet and two adjustable settings controlled by a knob. The listed design includes a die-cast aluminum burner and a foldable base. It uses a small 1-pound propane tank, which is not included.
Best for: Campers and outdoor users who want adjustable radiant heat without choosing a larger heater. The two settings provide a way to select gentler or stronger warmth, and the foldable base is a useful portability feature.
Limitation: The fuel tank is not included, and the listing describes this as an outdoor heater. Do not assume it is suitable for a closed tent, vehicle, or other enclosed area.
HEYDUOTON Compact Propane Heater
The HEYDUOTON heater is presented as a compact, cordless propane option for outdoor activities such as tailgating, hunting, and patio gatherings. Its listing emphasizes portability and says it should be used in a well-ventilated environment. Unlike some alternatives in this guide, the supplied product information does not state a BTU rating, coverage area, or number of heat settings.
Best for: Buyers who prioritize a portable, cordless heater for outdoor use and do not need to compare products by a listed BTU figure. It was selected because its stated use cases align with camping and other outdoor activities.
Limitation: The listing provides limited performance specifications, so it is harder to compare its heating capacity with the Mr. Heater models. Check the product instructions for fuel requirements and permitted operating locations before use.
YZO Portable Diesel Air Heater
This heater is a diesel-powered alternative, not a propane or gas camping heater. The listing specifies an 8KW unit, a 2-gallon tank, an LCD switch, and a remote control. It supports 12V or 24V vehicle power and includes a transformer for 110–240V household power. Listed features also include a thermostat, programmable timer, preheating, and overheat protection.
Best for: Buyers who specifically want a diesel heater for a vehicle, RV, truck, boat, or campervan setup and can accommodate its power and installation requirements. It was included as a fuel-type alternative for people comparing portable camp heating options.
Limitation: This is not a simple propane radiant heater. Its electrical supply, fuel, exhaust, and installation needs differ from those of the propane models. Review the manufacturer’s instructions carefully before use, particularly for any vehicle or indoor application.
Mr. Heater Big Buddy PRO
The Big Buddy PRO offers three listed settings: 4,000, 9,000, and 18,000 BTU. Its stated coverage is up to 450 square feet, making it the highest-output propane option among the products here. The listing says it can run for up to 216 hours on two 20-pound propane tanks at the low setting when used with an optional hose.
Best for: Campers or other users who need a higher stated output and want several heat settings. It was selected for its broad listed coverage and adjustable output, which distinguish it from the smaller Portable Buddy.
Limitation: The long runtime claim applies to the low setting and two 20-pound tanks with an optional hose; it should not be treated as a runtime estimate for other settings or fuel arrangements. Its larger coverage figure does not make it appropriate for every enclosed space.
Buying Guide: How To Choose A Portable Camping Heater
Should you choose propane or diesel?
Fuel type is a key first decision. The four propane products in this guide are radiant heaters intended to provide direct warmth in outdoor or specified settings. The YZO model uses diesel and has different fuel, power, and setup requirements. Choose a diesel unit only if its electrical supply and installation approach fit your camping setup. Do not treat a diesel heater as interchangeable with a small propane radiant heater.
How much heat output do you need?
Compare the stated BTU ratings when they are available. The Portable Buddy lists 4,000 and 9,000 BTU per hour, while the Big Buddy lists 4,000, 9,000, and 18,000 BTU. Higher output may be useful for larger or colder spaces, but the listed square-foot coverage is a product specification, not a guarantee of comfort in every campsite. Wind, ambient temperature, and the space’s configuration can affect how warmth is experienced.
The two compact outdoor propane listings provide less complete information. One states coverage up to 200 square feet and two settings; the HEYDUOTON listing does not provide a BTU rating or coverage figure in the supplied details. If measurable output is important to your decision, favor a product with clearly listed specifications.
Where will you use the heater?
Check the manufacturer’s instructions for the exact locations and conditions allowed. An outdoor-use description is not permission to operate a heater in a tent, camper, car, or other enclosed area. Even a product described as approved for indoor and outdoor use must be operated according to its manual. Combustion heaters can create carbon monoxide, an odorless, potentially deadly gas. Keep the heater away from sleeping occupants and follow all ventilation and clearance directions.
Never use a heater in a space where its manual prohibits operation. Use a working carbon monoxide alarm where appropriate, but do not treat an alarm as a substitute for correct use and ventilation. Keep heaters on a stable surface and away from fabric, bedding, and other combustible materials.
What fuel and accessories are included?
Confirm whether the required fuel container, hose, or power source is included before planning a trip. The compact propane model explicitly says its 1-pound tank is not included. The Big Buddy’s runtime detail mentions an optional hose and two 20-pound tanks. The diesel heater requires diesel and an electrical input; its listing describes support for vehicle voltage and a household transformer. Verify exact requirements in the product documentation.
How important are portability and controls?
For short outdoor outings, a compact cordless design and foldable base may matter more than a high maximum output. For longer stays or larger areas, multiple heat settings and higher listed capacity may be more important. A thermostat, timer, or remote may be useful for a diesel setup, but these features also mean the heater is more complex than a basic radiant propane model.
Before buying, compare the heater’s dimensions and weight, which are not supplied for every product here. Also consider how you will transport fuel safely, protect the heater from damage, and store it when it is not in use. Follow all fuel-container and equipment handling instructions.
Frequently Asked Questions
What is the best portable gas heater for camping?
The best choice depends on the setting and heat needs. The Mr. Heater Portable Buddy offers two listed BTU settings and is described as approved for indoor and outdoor use. The Big Buddy provides higher stated output for users who need more heat. Always follow the specific manual.
Can I use a propane heater inside a tent?
Do not assume a propane heater is safe inside a tent. Use it there only if the manufacturer’s instructions explicitly permit that specific use and all required ventilation and clearance rules can be met. Never use a heater where the manual prohibits it.
Which product has the highest stated propane output?
The Mr. Heater Big Buddy PRO has the highest stated propane output in this selection, with settings of 4,000, 9,000, and 18,000 BTU.
Does the compact two-setting propane heater include a fuel tank?
No. Its listing says it uses a 1-pound propane tank that is not included.
Is the YZO heater a propane camping heater?
No. The YZO product is a diesel air heater. It requires diesel fuel and an electrical power source, so it is not a direct substitute for a propane radiant heater.
What safety precautions matter most with a camping heater?
Follow the manufacturer’s instructions for location, ventilation, clearances, fuel, and operation. Keep the heater stable and away from combustible materials, and never operate it in an enclosed space unless that use is explicitly allowed.
