- Clip-on installation
- Designed for a specific MH9BX version
Cons

Mr. Heater: Best for hunting trips
- 6,000 or 12,000 BTU per hour
- Heats up to 300 sq ft

- Can connect to a 1 lb tank
Cons
- Match-light start knob
The Hunting Buddy provides 6,000 or 12,000 BTU per hour and is rated to heat up to 300 sq ft. That places it between the Portable Buddy and Big Buddy by maximum output.
It uses propane and has a single control start knob with match light. The heater can connect to a 1 lb tank, with larger tanks requiring an optional hose.
Choose it when you want more output than the 9,000 BTU Portable Buddy but do not need Big Buddy's 18,000 BTU setting. For more models in the brand's range, see [the best Mr.
Heater propane heater options](/best-mr-heater-propane-heater/).
How did we compare these Buddy heaters?
We compared stated heat output, coverage, controls, fuel connections and use approval to match each heater with a clear job. Our score weighs specs and features against what shoppers want from the Buddy family.
The Portable Buddy models suit buyers who want two heat settings and a portable format. Little Buddy trades output for a smaller footprint, while Big Buddy adds a third setting and a fan.
Accessories are included because heat distribution and fuel setup can affect how a portable heater fits a use case. Check accessory compatibility carefully, since a fan or hose made for one Buddy model may not suit another.
What should you consider before choosing a Buddy heater?
Choose by the space you need to heat, the location where you will use it and the fuel setup you can manage.
For a fixed workspace, see our guide to electric garage heaters. Natural gas garage heaters are another option for a permanent workspace.
A higher BTU rating is useful only when it fits the room and the model's approved use.
Is a 9,000 BTU or 18,000 BTU Buddy better?
The 9,000 BTU Portable Buddy is rated for up to 225 sq ft, while Big Buddy reaches 18,000 BTU and up to 450 sq ft. Use those coverage figures as a starting point, then consider room layout, outdoor conditions and the heater's instructions.
For an indoor space, confirm that the specific model is approved for that location. The Midnight Series models in this roundup are not approved for indoor use in Canada or Massachusetts.
When does Little Buddy make sense?
Little Buddy is the smallest-output heater here at 3,800 BTU per hour, with stated coverage up to 95 sq ft. It has one heat setting, one-button ignition and an 8 in round stand.
That combination fits a compact area where a single setting is enough. For a larger space or more control over output, compare it with the 9,000 BTU Portable Buddy.
Can a Buddy heater run from a 20 lb tank?
Some Buddy models support a larger tank connection with an optional Buddy hose and fuel filter. The exact setup varies, so use only accessories approved for your heater and follow the manufacturer's instructions.
The Yigiao hose in this guide is designed for certain Buddy models, including MH9B and MH18B. Confirm model compatibility and the connection requirements before using any adapter.
Is a propane Buddy heater safe for a garage?
Check the exact model's approved location and follow its safety instructions before using it in a garage. Garage use depends on the heater's approval, ventilation, clearances and local requirements.
Read our guide to whether it's safe to use a propane heater in a garage and compare propane heaters for garages before deciding.
Which Mr. Heater Buddy should you choose?
Choose Portable Buddy for two heat settings and portable 9,000 BTU output, Little Buddy for a compact area, or Big Buddy for up to 18,000 BTU and a built-in fan. Pick Hunting Buddy when its 12,000 BTU maximum better fits your planned space.
