Number 3. Hotdevil Tent Heater HD-6001 – Best Budget Portable Heater
Hotdevil Tent Heater HD-6001 features a simple, almost classical design, and pairs it with a low price tag to become an attractive buy. The radiant heater is great at providing quick, targeted warmth, though considering its small size, it’s not much of a space heater. The targeted warmth aspect might even be better for those who intend to use it outdoors or while camping.
It has three major parts to be a functional heater. The simple assembly has a small footprint and low weight, so taking it outdoors isn’t difficult. The first part is the plastic base, which provides stability to the heater assembly and ensures that it stays upright. It also folds for easier storage and portability.
The second part is the gas cylinder. The company recommends using the conventional 1 lb propane cylinder, which is also the size that fits into the base comfortably.
The third part is the top assembly which includes the control valve, burner, and reflector. Interestingly, all of these are made of different materials. The valve is made from brass for durability and to prevent leakages. The burner is made of steel to be long-lasting and stable, while the 6-inch reflector is made from aluminum to be lightweight and cost-effective.
The heater doesn’t have automatic switching, so you’ll have to use a lighter on the burner to get the heat and fire going. The protective grid or fire guard on the reflector is spaced close and does a good job of preventing someone from accidentally touching the reflector or the fire. However, it gets pretty hot itself, so caution must be exercised.
The output heat is listed as 6200 BTU, though it’s going to be much lower for practical use . Additionally, when employed at full heat, the heater consumes 122.5 grams per hour of fuel, so a full cylinder can go out in 3-4 hours.
It’s smart to employ some precautions when using this basic heater, especially if you’re operating it in an enclosed space like a tent. Even though the base does a good job keeping it in place, this budget heater doesn’t have protection if it tips over. There is no oxygen sensor either, so keeping an eye for ventilation becomes important..
Also, if you’re using it in a tent, keep in mind that most modern tents are made from nylon or similar fabrics. These fabrics can easily get damaged or singed from heat and may even catch fire. If the tent has mesh, the damage may take even longer to notice.
Propane produces water vapor when it burns. So, if you’re using such heaters in an enclosed space, be prepared for some condensation.
Overall, Hotdevil Tent Heater HD-6001 is a great pick for those who want a small and easily portable heater. The radiant heater works well for those who want direct, targeted heat, but isn’t that useful as a space heater.
To sum up, what we like is the…
Attractive pricing
Simple to use
Lightweight and easily portable
Folding base provides stability and ease of storage
Decent heating.
On the downside…
No protection for tripping
No CO or oxygen sensor.

Number 2. Mr. Heater Buddy Radiant Heater – Best Premium Portable Heater
Mr. Heater and the Buddy series are both extremely popular and well-known for delivering performance and quality. So, it should be no surprise that the Mr. Heater MH9BX Buddy radiant heater gets a place on our list.
It is designed to heat relatively large areas but is still surprisingly compact. Its height is 15 inches, and that includes the fold-down handle on the top. The large handle runs the entire width of the heater, making it quite convenient to carry it around when necessary.
Another similarly space-saving touch here is the swivel-out regulator that stays out of the way unless necessary. It attaches to a regular propane tank and is all set for action. The available space in the heater is just the right fit for a 1 lb propane cylinder. The swivel regulator also helps should you choose to use a larger cylinder or a remote supply.
When ready for heating, just move the knob to the pilot position and push it. A built-in sparking mechanism will light the heater and it will start giving off heat immediately. The change is visible visually. If you don’t see such a change, it’s best to try again or light the heater using alternate means but make sure you do not leave the gas on if the heater doesn’t light up.
Its rated power is 4,000-9,000 BTU and it distributes the heat quite well, so warming a small space should be easy. This includes tents up to 225 square feet in volume. Bigger, taller tents work better than conventional smaller tents. Anything that’s flammable or can be damaged by heat should be kept at a decent distance from the heater to avoid damage and accidents.
On a positive note, it does take safety quite seriously and automatically switches off if specific conditions are met. These include if the heater tips over, if the pilot light goes out, or if it detects low oxygen levels. Each of these could be a potentially dangerous situation, so the heater going out automatically is preferable and desirable.
Even though the unit has an oxygen sensor and the fire burns clean, it’s important to not underestimate the importance of ventilation. Carbon monoxide buildup is still possible and the risk should not be taken lightly.
Similarly, you will want the water vapor generated from burning propane to dry out, so that the condensation doesn’t get too problematic.
The heater is easily portable and performs almost flawlessly. However, it can have issues when used in places with altitudes over 7,000 feet. It will still work but might shut off often.
Overall, Mr. Heater Buddy Radiant Heater MH9BX is a great pick for those who want a small space to be heated up quickly. The soft glow with the heat is a nice touch and adds to the ambiance.
To sum up, what we like is that…
Simple to use
Compact and easily portable
Can work with attached propane cylinder or remote supply
Sensors for auto shut off for several situations
Good and quick heating.
On the downside…
Can be unreliable on low heat setting.
Might automatically shut off at altitudes over 7000 feet.

Number 1. Mr. Heater MH4B Little Buddy – Our Top Choice
The small, almost cute-looking and lamp-like Mr. Heater MH4B Little Buddy is our top choice for this category. The tiny heater provides quick and directed heat, while also having the necessary safety features to prevent mishaps.
You could use it as a porch heater or take it outdoors and stay warm in a tent. The output heat is rated at 3800 BTU and it is claimed to heat an area of 95 square feet. That should be good enough for a small tent or even make a slightly larger area warmer.
As comfort goes, the direct heat should provide immediate warmth to one or two people close to the heater. It’s fairly consistent with the heat, and the lampshade-like design also protects it from wind or similar disturbances close to the heater.
There are three parts to this heater. Starting from the bottom, there’s a small, but surprisingly stable plastic base that keeps the heater in the right position. It also holds the 1 lb propane cylinder required to power the heater. Due to the low heat output, even the small propane cylinder can easily last 5-6 hours of continuous use.
In most heaters, the cylinder would be followed by a regulator or control knob. That is not the case here. Instead, a steady flow of gas is maintained from the cylinder to the burner. Pushing the “On” button at the side of the heater will activate the piezo system and the heater will light up. No external lighter is necessary to light the gas in the burner.
When it’s time to switch off the heater, you can press and hold the “Off” button near the “on” button to cut off the gas supply.
Small as the heater is, it doesn’t skimp on safety features. It will shut off if tipped over, or if the sensor detects low oxygen. This is a small, clean-burning heater, so carbon monoxide buildup isn’t a big threat. Yet, it would be sensible to consider some ventilation when using it.
A sturdy grip at the back of the reflector makes it easy to carry this heater around or attach it to a backpack. Of course, the base stand and cylinder should be removed and packaged separately to carry the heater this way.
Overall, Mr. Heater MH4B Little Buddy is a great pick for backpackers in cool and cold weather and for those who would prefer some heating in their tent. It’s compact, lightweight, and provides decent features to be considered reliable.
To sum up, what we like is that…
Compact and lightweight
Simple use
Sensors for auto shut off for several situations
Decent and quick heating.
On the downside…
Problematic operation on altitudes above 7000 feet.
