Mr. Heater Portable Buddy MH9BX
Overview: The MH9BX is a compact radiant heater delivering 4,000–9,000 BTU with infrared-style, object-focused warmth. It’s intended for use in enclosed or semi-enclosed spaces up to approximately 225 square feet. The unit uses a durable Piezo igniter for matchless starts and emphasizes quick radiant heat delivery.
Key Features: The product lists powerful radiant heat with adjustable BTU settings, an improved tip-over safety switch that audibly engages if disturbed, and reliable piezo ignition. The heater directly warms nearby objects and people rather than relying solely on air temperature.
Practical Use: Suitable for campers who want direct warmth in tents, screen rooms, and small RV spaces. The radiant design makes it effective for spot heating rather than whole-space convection heating. Note the tip-over safety system that helps reduce risks during movement or accidental bumps.

Overview: The Little Buddy MH4B is a lightweight indoor-safe propane heater providing 3,800 BTU with a 45° heating angle and coverage up to 95 square feet. It’s designed for compact spaces where minimal heat and portability are priorities.
Key Features: Built-in automatic low oxygen shut-off system (ODS), accidental tip-over shut-off, and patented cross-thread protection make this a safety-focused option for enclosed environments. It can run about 5.6 hours at max on a 1-pound cylinder (cylinder not included).
Practical Use: Appropriate for small tents, enclosed vehicle spaces, or as a short-duration emergency heater. The low BTU output makes it less suited for larger tents or open-air warmth but useful for close-range, personal heating with several built-in safety measures.
Mr. Heater Hunting Buddy MH12HB
Overview: The MH12HB Hunting Buddy outputs 12,000 BTU, intended for larger camping areas, hunting blinds, and small cabins up to 300 square feet. It is built to operate safely at elevations up to 7,000 feet.
Key Features: Safety systems include low oxygen shut-off (ODS) and tip-over shut-off. The unit includes a swivel regulator to accept disposable cylinders or connect to a remote gas supply with an optional hose and filter.

Practical Use: Designed for hunters, anglers, and cold-weather campers who need higher output without sacrificing portable convenience. The swivel regulator increases fuel flexibility; consider additional accessories if you plan extended runs from larger tanks.
Mr. Heater MH9BX Massachusetts/Canada Approved
Overview: This MH9BX variation is similar in output to the standard MH9BX with 4,000–9,000 BTU and coverage up to 225 square feet, but specifically listed as compliant for certain regional regulations.
Key Features: The product is described as nearly 100-percent efficient with clean-burning operation and includes auto shut-off mechanisms for tip-over, pilot failure, and low oxygen detection. The listing notes potential performance changes at altitudes above 7,000 feet.
Practical Use: Useful for campers in regions with specific equipment approvals or for those who prioritize certified models. As with other radiant units, it’s most effective for targeted, close-range heating rather than whole-tent warming.
Mr. Heater 18,000 BTU Big Buddy
Overview: The Big Buddy is a higher-capacity portable heater with adjustable settings from 4,000 up to 18,000 BTU, capable of heating spaces up to 450 square feet. It’s approved for both indoor and outdoor use and emphasizes high output.
Key Features: The unit lists automatic shut-off features for tip-over, pilot light outage, and low oxygen detection. The wide BTU range allows for flexible use from small tents to larger enclosed spaces or porch areas.
Practical Use: Best when larger heat coverage or higher output is required, such as bigger RVs, workshops, or large communal tents. Because of higher output, ventilation and fuel supply considerations are more important than with low-BTU units.
Buying Guide: How To Choose The Right Camping Buddy Heater
Selecting the right Buddy-style propane heater depends on five primary considerations. Review each area below to match the product features to your camping needs.
1. Heat Output And Coverage
BTU Rating indicates the unit’s maximum heat output. For personal or small tent use, 3,000–4,000 BTU is often sufficient. For larger tents, hunting blinds, or shared spaces, consider 9,000–18,000 BTU models. Higher BTUs increase coverage but also fuel consumption and ventilation needs.
2. Safety Features
Look for ODS (oxygen depletion sensor), tip-over shut-off, and pilot/fail-safe features. These systems reduce the risk of carbon monoxide buildup and accidental fire. For enclosed tent use, confirm the heater is explicitly rated for indoor or enclosed-space operation and follow manufacturer ventilation guidance.
3. Fuel Type And Runtime
Most Buddy-style heaters use 1-lb disposable propane cylinders by default, with some models adaptable to larger tanks via optional hoses and filters. Consider run time at maximum BTU and whether you need the flexibility of connecting to a larger tank for extended use.
4. Portability And Size
Weight and physical size matter for backpacking vs. car camping. Smaller units like the Little Buddy are lighter and easier to carry but offer lower output. Bigger models provide more heat but add weight and require more fuel.
5. Altitude And Environmental Conditions
Some heaters perform differently at higher altitudes. If you camp above 7,000 feet, check manufacturer notes and consider models rated for elevation or expect occasional shut-off behavior. Cold temperatures can also affect cylinder pressure and runtime.
6. Ignition And Ease Of Use
Reliable ignition systems like Piezo igniters avoid the need for matches or batteries. Simple control knobs and clear fuel connection options reduce setup time and allow safer operation in low-light or cold conditions.
7. Regulatory Approvals And Local Restrictions
Certain states or regions have equipment approvals or restrictions (for example, models labeled for Massachusetts/Canada). Verify regional compliance if you plan to use the heater in regulated areas.
8. Intended Use Cases
- Personal/Small Tent Use: Prioritize low-BTU, ODS-equipped units for spot heating.
- Hunting/Blinds: Choose camo or higher-output models with swivel regulators for fuel flexibility.
- Large RVs/Enclosed Areas: Higher BTU units with ventilation plans are preferable.
- Emergency/Short-Term Heat: Compact units with reliable ignition and built-in safety features are most practical.
9. Accessories And Upgrades
Consider optional hose and filter kits for connecting to bulk tanks, or add-ons like stove fans or mounting brackets to improve heat distribution. Accessories can extend runtime, increase comfort, and adapt the heater to different fuel sources.
10. Multiple Perspectives For Comparison
When comparing models, evaluate:
- Safety Versus Output: Higher BTU models require more ventilation; low BTU models may be safer for tightly enclosed spaces.
- Portability Versus Coverage: Lightweight units offer convenience but limited area warming; larger units handle bigger spaces but add bulk.
- Fuel Flexibility: Units with remote-tank compatibility lower long-term fuel logistics but add setup complexity.
- Region Compliance: Region-approved models may be necessary based on local regulations.
Use this guide to weigh comfort, safety, and logistics for your camping style. Prioritize certified safety features for any enclosed-space heating and plan fuel and ventilation accordingly.
