A must for cold nights

This camping heater has been a total game-changer for our outdoor adventures. It's so compact and lightweight, making it easy to toss in our camping tote without taking up too much space. The heat output is impressive, and it's been a lifesaver on those chilly nights. It's also really easy to set up and use, which is a big plus. We've had nights where the temperature dropped significantly, but this heater kept our tent cozy and warm. Safety features are also a big plus, giving us peace of mind while we're camping. Overall, it's a fantastic piece of gear that I'd highly recommend to any camper or outdoor enthusiast. I recommend the extension hose for the bigger propane tank.

Great little radiative heater

The thing to know about this heater is it throws off a lot of infrared radiation, which is the primary mode of heating. It is like having a little portable Sun with you. Like if you go outside and it is cold and cloudy, you will feel cold. But at the same outdoor temperature and the Sun beating down on you on a clear winter day (if you have clear winter days were you live), you will feel a lot warmer. A fun little thing to do if you have security cameras with night vision, light this up in view of one of these security camera's at night. It is brilliantly bright and everything in the line of sight of the hot plate on it nearby is brilliantly lit up. With the naked eye at night, you will just see a dim red glow, but the security cameras will see a blindly bright light as it is in IR night vision mode and the black body radiation is primarily in the infrared spectrum. This means when you are outside, basically regardless of conditions, as long as the conditions are good enough for this to work, it will be heating you up. You can even say leave this outside your tent and as long as you are setup to let the infrared light in, it will warm up the inside of your tent and any infrared light hitting you from this will warm you up, say you are laying there in your sleeping bag. It is almost like magic as most people are used to thinking about heating in convection terms while this primarily operates in black body radiative terms. I am not saying sit out there butt naked in the snow with this being your only device to keep you warm, but it is a greet supplemental heat source to help you keep warm when you are doing something sedentary outside in the cold.The one gripe I have about this is the flame is unstable and noisy on the low setting. This works best at the high setting anyway, so probably what you want to do and just forget about the low setting.If you use this with a larger tank with a hose, you may want to plan to shut the main valve off on the larger external tank a couple to a few minutes before you are done using the heater so that there is time for a pressurized hose to purge. As this only lasts a few hours on a 1 lb tank, you can quickly end up getting into using larger tanks with this.

Great for a kodiak

I love this little heater! It's really changed the whole camping experience. I camp at an event where it can get down into the 30s at night and this heater was a champ. I notice that it smells a little funny and that's a bit disconcerting (and I turned it off in the middle of the night once because I was concerned I hadn't opened enough windows) but once I got used to it, it worked fine. I also noticed that it will dry out the air a bit, which is good, but just keep that in mind. I felt safe because of the oxygen cutoff sensor too. The heat output is excellent. The tent was so nice and cozy I didn't even need to zip up my sleeping bag. I did keep all of the windows open about 2-3 inches just to be safe.

A Must-Have for Winter and Overlanding – Quick, Efficient, and Reliable!

The Mr. Heater Portable Buddy Heater (MH9BX) is easily one of my favorite overlanding products! I first discovered this heater through the Camping With Steve YouTube channel, and I can see exactly why it’s so popular. This little heater packs a serious punch, offering 4,000-9,000 BTU of radiant heat, and it’s safe for indoor use, which is perfect for camping or overlanding in colder conditions. What I really love is that it runs on the same 16 oz propane mini tanks that power my Coleman Stove, making it super convenient to use with the gear I already have.The performance is absolutely impressive. The heat kicks in quickly, almost immediately after the pilot light turns on. Within just a few minutes, the area around it is toasty and warm. It’s amazing how such a compact heater can heat up a small space so efficiently. It’s also incredibly clean and quiet once it’s running—aside from a very slight propane smell when first lighting, I barely notice it after that. It’s the perfect addition to my setup when I’m in the middle of nowhere and need to stay warm.In all seriousness, other companies should take notes on this heater’s design and materials. It’s clear that a lot of thought went into making it durable, portable, and easy to use. The build quality feels solid, and I trust it to keep me warm during my overlanding trips. It’s one of those products that you never knew you needed, but once you have it, it becomes essential.As a loyal customer, I can honestly say I’ll be using this heater for a long time. It's a lifetime keeper for me, and I wholeheartedly recommend it to anyone looking for a compact, reliable, and efficient heating solution for their camping or overlanding adventures.
