10 Best Portable Gas Heater 2026 in the United States

The Heatstar 30000 Btu Vent Free Radiant Propane Heater is a solid choice for those needing a portable heating solution. With a substantial heating capacity of 30,000 BTU, it can comfortably warm larger spaces. The use of propane as a fuel type means it’s quite efficient and convenient for areas where electricity might not be reliably available. One standout feature is its top-mounted adjustable thermostat, which allows you to control the heat output with ease. Additionally, the battery-operated electronic ignition makes it simple to start without fumbling for matches or lighters.

The heater is flexible in terms of placement, as it can be wall-mounted or used freestanding, thanks to the included feet kit. This adds to its portability, making it easy to move and set up in different areas as needed. Safety is a priority with this model, which includes a built-in low oxygen sensor to prevent hazardous conditions. However, it's worth noting that while the heater operates without electricity, the blower requires power. This means that during a power outage, the heater will still work, but without the blower's enhanced heat distribution.

The unit is relatively lightweight at 1 pound, so transporting it should be hassle-free. The black color and compact design ensure it blends well with most interiors. On the downside, some users might find that the need for an AA battery for ignition and power for the blower adds a layer of maintenance. Nevertheless, the Heatstar 30000 Btu Vent Free Radiant Propane Heater is an efficient, safe, and portable option that suits various heating needs, especially in areas prone to power outages.

The Mr. Heater MH540T is a powerful portable propane heater designed for outdoor activities like camping, hunting, and tailgating. One of its key strengths is its impressive heating capacity, offering up to 45,000 BTUs with three adjustable heat settings (high, medium, and low). This allows users to customize the warmth to their preference, making it versatile for different weather conditions. The 540-degree radiant coverage is another standout feature, providing wide-reaching heat by combining a 360-degree burner and a 180-degree swivel bracket, effectively warming both people and objects directly around it.

Safety is a priority with this heater, featuring a tip-over safety shut-off that automatically turns the heater off if it’s knocked over, preventing accidents. Additionally, the secure, leak-free connection ensures dependable and safe operation. In terms of ease of use, it boasts a push-button TE valve for quick ignition and also offers a manual match-lit ignition as a backup. However, it’s important to note that this heater is for outdoor use only, which limits its versatility.

Portability is a major plus, as it’s lightweight at just 5.5 pounds and doesn't require any assembly, making it easy to move and set up. On the downside, because it uses propane, it may not be the most energy-efficient option compared to electric heaters. The Mr. Heater MH540T is an excellent choice for those needing a reliable and powerful source of outdoor heat, particularly for active outdoor enthusiasts.

The Mr. Heater MH9BX Portable Buddy Heater is a solid choice for anyone needing outdoor heating in spaces like campers, porches, garages, or sheds. It offers two adjustable heat settings—4,000 BTU for smaller spaces and 9,000 BTU for larger areas up to 225 square feet—giving you control over your comfort and fuel use. It runs on propane gas, compatible with small 1-pound cylinders or larger 20-pound tanks if you have a hose, though the hose and tanks are sold separately. This flexibility is great for portability and longer use.

Safety is well-covered with an automatic oxygen depletion sensor and a tip-over shutoff, which are important for preventing accidents. The heater also has a sturdy handle and protective wire guard, making it easy and safe to carry around. It is designed for outdoor use only, so it’s not suitable for indoor heating inside homes. Since fuel, hose, and batteries are not included, you need to buy those separately, which might add to the setup cost.

The heater runs up to 6 hours on low and about 3 hours on high, so it’s good for short to medium periods without refueling. This model is a dependable and portable option if you want straightforward, adjustable heat for outdoor or semi-enclosed spaces and value safety features in your portable gas heater.
