10 Best Portable Gas Heater 2026 in the United States

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.

The aluminum reflector is durable and suited for rough outdoor environments.

A limitation of this heater is that it uses small propane tanks, which might not last for very long without replacement, so it is best suited for shorter outings or as supplementary heat. Additionally, it is meant for outdoor use only and may not be suitable for large indoor spaces. For those seeking a simple, portable source of heat for camping or outdoor relaxation, this heater offers a nice balance of power, portability, and safety features.

The heater also boasts push-button ignition for easy start-up and does not require electricity, making it reliable during power outages. Its portability is enhanced by its compact design and the inclusion of wall mount hardware and base feet, allowing you to place it on the floor or mount it on the wall. However, it weighs nearly 16 pounds, so it might be a bit heavy for frequent relocation. Another downside could be the lack of advanced features like timers or remote controls found in some other models.
