The Mr. Heater Portable Buddy Heater MH9BX is a well-regarded option in the camping heater category, particularly suited for tent use due to its powerful heating capabilities and safety features. With a heating capacity ranging from 4,000 to 9,000 BTUs, it efficiently warms spaces up to 225 square feet, making it ideal for those chilly nights outdoors. Its radiant heating technology provides a cozy warmth that directly heats objects and people, rather than just the air, which can be particularly beneficial in enclosed spaces like tents.

Safety is a notable strength of this heater. It includes an improved tip-over safety switch, which automatically shuts off the heater if it gets knocked over, ensuring peace of mind while you sleep. Additionally, the low-oxygen safety shut-off system is a crucial feature for indoor and tent use, preventing any hazardous buildup of gases.

Portability is another key asset, as it weighs just 8.53 pounds and has a fold-down handle, making it easy to carry. The heater is designed for flexible fuel options, allowing connection to both 1-pound and 20-pound propane tanks, which adds convenience for campers. However, while it operates quietly, some users might find the noise level slightly higher than expected during operation, especially on the higher BTU setting. Additionally, the heater’s run time, which is about 6 hours on low and 3 hours on high, could be limiting for longer camping trips unless additional fuel is on hand.

The heater's three heat settings allow for customizable warmth, which is a plus for varying weather conditions.

Portability is another strength of this heater, weighing just 15 pounds and designed for easy transport. The straightforward single control knob enhances user-friendliness, and the piezo sparking mechanism adds reliability for quick ignition. Safety features like the automatic shutoff if tipped over and low-oxygen shutoff give peace of mind, especially when used indoors.

There are a few drawbacks to consider. While it boasts impressive heating capacity, the lack of included accessories like the hose and filter means additional purchases may be necessary to get started fully.
