Mr. Heater Little Buddy Portable Heater Review

The Mr. Heater Little Buddy Heater reigns supreme as one of the best portable heaters for those on a budget.

Clocking in at well under $100, this budget propane heater is not only lightweight and compact, but it’s also surprisingly powerful and efficient (although it does have its limitations). Built-in safety features ensure your safety, even in enclosed spaces.

Although the slightly larger and more powerful Mr. Heater Portable Buddy is perhaps a better tent heater overall, don’t overlook the Little Buddy if want something a little smaller and more compact.

Our Opinion of the Mr. Heater Little Buddy Heater

I’ve always been a big fan of winter
– but, boy, can it get cold.

A cold-weather
sleeping bag
and 4-season
keep me warm enough, but the extra heat from a portable tent heater is
a blessing when the temperatures dip well below freezing.

Although the Little Buddy from Mr. Heater is far too bulky
for backpacking, it’s the perfect size for car camping. It’s also ideal to use
in an RV, trailer, or camper van. I also use mine at home while working in the
barn and as an emergency heater for power outages.

As much as I like the Little Buddy Heater for its power output and efficiency, it does have its drawbacks. Namely, it’s really not all that little. It also has only a single heat setting which somewhat limits its functionality.

That said, I still love the Little Buddy for heating up an unheated workspace, warming up my tent before bed and when I wake up in the morning, and especially around the campsite when I can’t build a campfire.

Heat Output

The Mr. Heater Little Buddy produces 3,800 BTUs per hour. It
has a single heat setting (no heat adjustability) and runs for roughly 5.5
hours straight on a single 1-lb cylinder of propane.

Mr. Heater claims that the Little Buddy can efficiently heat a space up to about 95 square feet. I’ve found that, although this is true, it doesn’t really warm up a room as much as it provides a direct heat source. The Little Buddy is definitely a personal heater.

I’ve used the Little Buddy in a variety of different
settings. Most often before sleep and upon waking in my tent, in my unheated
workspace, and working on projects outdoors. It’s provided adequate direct
heat, even in temperatures below freezing. It heats up my 2-person tent to a
comfortable temperature in just minutes.

Safety Features

Mr. Heater gives the Little Buddy an oxygen depletion sensor
and an accidental tip-over shutoff for improved safety. There is no high-limit
safety shutoff or even a built-in carbon monoxide detector like you find on
many other winter tent heaters.

Although I certainly appreciate these safety features, the
accidental tip-over shutoff is a bit too sensitive. When using the heater on an
uneven surface (like the ground outside), the switch is prone to automatically
turn the heater off with the slightest jostling.

Interestingly, Mr. Heater simultaneously states that the
Little Buddy is for outdoor use only while also labeling it as a tent heater
safe for small, enclosed spaces. 

Personally, I don’t run the Little Buddy during the night. I know a lot of people that do run the heater through the night in confined spaces (with proper ventilation and a separate carbon monoxide detector) with no problem. I prefer to only run my propane tent heaters for shorter periods of time while awake but, then again, I stay plenty warm even on cold winter nights in my 0° sleeping bag.

Size & Weight

The Mr. Heater Little Buddy clocks in at 5.85 lbs (not
including the weight of the 1-lb propane canister).

Naturally, this is much too heavy for winter
, but the weight is no big deal for car camping, hunting, RVing,
or anything else where you’ll largely in the same place. 

Because of the name (and my prior experience with the slightly larger Mr. Heater Portable Buddy), I expected the Little Buddy to be smaller. But it’s relatively bulky. Once again, this isn’t much of an issue as the heater isn’t exactly meant to be compact and lightweight to begin with. An integrated carry handle does make it easy to move from place to place. 

Ease of Use

Ease of use is one area where the Little Buddy really

The two-part tent heater consists of an 8-inch base piece
and the actual heater. Screw your 1-lb propane cylinder onto the underside of
the heater. Then set the bottom of the propane cylinder into the base piece to
act as a stable platform.

From here, using the device consists simply of using the
piezo ignitor ignition button to light the heater. With no temperature control,
the Little Buddy will take care of the rest itself.


Like all Mr. Heater products, the Little Buddy is built to

Built from a combination of metal, high-temperature plastic,
and ceramic materials, this winter tent heater will last for years on end, even
factoring in the bangs and bruises of camping.

Overall Value

You won’t be disappointed by adding the Mr. Heater Little
Buddy into your winter camping arsenal.

Not only does the heater get the job done by quickly and
efficiently heating small spaces, but it’s rugged and durable design ensures it
will continue doing the job for years on end.

The Little Buddy typically sells for between $80 and $90, although it can almost always be found for around $50 with a little shopping around.

Is the Mr. Heater Little Buddy Heater Right for You?

The Mr. Heater Little Buddy ranks as one of my favorite tent
heaters for winter camping

It’s simple and straightforward with a rugged and durable
design. It’s so easy to use that it’s all but impossible to use it incorrectly.

Furthermore, at 3,800 BTUs per hour, the Little Buddy
provides decent heat output for a portable propane heater. It can run for up to
5.5 hours off a single 1-lb propane cylinder, although I find it more effective
to run it in short spurts rather than continuously.

The Little Buddy is ideal for heating smaller spaces and for
those on a budget. It’s fantastic at warming up a camping
and will work well for most glamping tents
too. In an outdoor setting or any interior space larger than 100 square feet,
the Little Buddy is best as a personal heater only.

If you think you need something a little bit more powerful, then consider upgrading to the Mr. Heater Portable Buddy. Two heat settings enable you to alternate between 4,000 and 9,000 BTUs per hour to heat an indoor space up to 200 square feet (according to the manufacturer).

The Verdict

You can’t go wrong with any winter tent heater from Mr.

The Little Buddy stands out as their most portable model.
Although it’s not small by any means, it is small enough for use in most
camping tents. Despite its smallish size, it’s still powerful and efficient,
providing a more than decent amount of heat, even on the coldest nights.

If you’re in the market for a tent heater and don’t want to
break the bank, you’ll be hard-pressed to go wrong with the Mr. Heater Little
