Propane fire pits eliminate the wood, smoke and flying embers of a traditional campfire, but much of their heat can disappear into the air above them. The Happy Caveman Campfire takes a different approach by putting the flame inside a vertical steel tube and turning the tube itself into a radiant heater.
Developed by San Diego-based Happy Caveman, the portable appliance weighs only 4 lb (1.8 kg) and stands 26 in (66 cm) tall. It is designed for vehicle camping, patios and other outdoor settings where people want warmth without hauling firewood or cleaning up ash.
An “inside-out” propane fire
The burner sits inside a tube made from 304 stainless steel. A restrictor plate slows the exhaust moving through the tube, keeping hot gases in contact with the metal until the surface begins glowing red and radiating infrared warmth like the coals beneath a wood fire.
Openings branded as ThermaFlux channels allow flames and hot exhaust to escape around the sides. Instead of sending nearly all the heat vertically, the arrangement directs part of it outward at roughly seated-body height.
Happy Caveman rates the burner at approximately 40,000 BTU per hour and says the tube can reach around 1,300°F (704°C). The output can be adjusted using the regulator supplied with the propane hose.
Four pounds—plus the propane tank
Three folding feet form the support base and tuck inward for transportation. The company says setup takes about one minute, with no wood to collect, fire lay to build or ash to remove afterward.
The appliance itself is genuinely light, but it is not a backpacking heater once fuel is considered. It is intended primarily for a standard 20-lb propane cylinder, which reportedly provides about nine hours at full output or 13 hours at half power. A 1-lb disposable cylinder would last only around 30 minutes at maximum output.
The main structure combines 304 stainless steel with 360 brass components. Happy Caveman says the product is designed, assembled and tested in San Diego, while the supplied hose and quick-connect fittings are imported.
Fire restrictions still need to be checked
Because propane produces no drifting embers and can be shut off immediately, appliances with control valves are permitted under many restrictions that prohibit wood fires. That does not make the Campfire universally legal during every ban; some stricter orders also prohibit recreational propane fire pits. Users must check the applicable campground or land-management rules before lighting it.
The manufacturer says the feet and surface underneath remain relatively cool, allowing correct use on wooden decks. The glowing tube itself is extremely hot, however, and must be kept away from children, pets and combustible objects while operating or cooling. Like any propane appliance, it is intended for outdoor use.
The Kickstarter FAQ says independent testing for safe combustion and carbon-monoxide output is planned before shipment. Formal gas-appliance certification is described as a later objective rather than something already completed.
Pricing and availability
The Kickstarter campaign ended after attracting $128,587 from 353 backers, more than 12 times its $10,000 target. Campaign pricing began at $350, while a widely offered $399 pledge included the Campfire and adjustable propane hose. Late pledges remain available through a limited $450 Post-Kickstarter Special, which also includes the Campfire and propane hose. Happy Caveman lists a planned retail price of $499.
The first “Founding Cavemen” rewards are estimated to ship in January 2027, with other original campaign tiers scheduled for February and March. Late-pledge orders are expected to follow in April 2027. Shipping is currently limited to US customers, and—as with any crowdfunded hardware—delivery dates remain estimates rather than guarantees.
For campers mainly interested in warmth rather than cooking over wood, the Happy Caveman offers a clever compromise: the instant control and clean operation of propane, paired with the radiant glow that ordinary gas fire pits often lack.
