What is the LOFI stove?

“The LOFI stove burns hotter, cleaner, and safer than a normal fire”

The LOFI Stove is small forced-air stove for backpackers, hikers, and campers that burns bio-fuel (think sticks, twigs and pellets). A tiny heatproof fan feeds the fire with a constant flow of air, boosting the efficiency of the stove and increasing the heat output of the fire.  It can be powered by a phone’s battery bank, the reverse charging function on modern phones, or even a small solar panel.

The clever design means that the base of the stove stays cool and it won’t scorch the ground (LNT), there is also a built-in “ember-guard” that captures stray sparks and doubles as a windshield, reflecting heat back into the cook-pot and protecting the fire from any rain or wind. The stove’s sides are double-walled and feed the fire with superheated air for a clean burn that doesn’t leave your pans covered in too much black soot.

The airflow is cleverly designed to cool the base of the stove when it is lit, this way it doesn’t damage or scorch the ground; There is also an integrated ember-guard which captures any sparks and embers released when you have your cook pot on top.

useful information

Made from titanium, this ultra-lightweight stove weighs less than 150grams (that’s less than a gas canister!) including the speed controller and cable. The controller allows for adjustment of the airflow passing through the stove, this in turn controls the heat output from the stove for boiling, simmering, and cooking.

The stove will burn most solid biofuels, this includes wood, sticks, wood pellets, charcoal, pinecones & bark. In emergencies, starchy or sugary foods can be used, such as corn chips, noodles, or even dry sheep’s dung to cook food at a push! Paper and card waste, or other tinder can be used to start the stove (see the videos on YouTube).

The LOFI stove will run for 15 to 150 hours on a 10,000mAh battery pack, and power use is just 55mA on the lowest setting and 500mA (2.5W) on high power.

All the electronic components have been coated in an additional protective silicone layer to provide reliability in even the toughest conditions, if the stove gets wet just dry it off. The speed controller is rated to IP67, equivalent to up to 1m of water submersion. 

How does it work?

The stove is double-walled, this allows secondary air (oxygen) to be added to the fire where it’s needed to help it burn efficiently, just like modern wood burners do in your home. The small internal fan has the same effect as a chimney would on a larger fire, drawing the air through the stove even when there is a pan on top – pretty clever huh!

The fire is lit in the burn chamber twigs, stick or wood-pellets as fuel, once lit the ember guard is placed over the fire, this not only focuses the flame into a vortex, it also helps make the stove fully windproof, and captures any stray sparks.

The stove’s heat is controlled using the small speed controller, this is supplied with the stove and this controls the amount of oxygen passing through the fire and therefore controls the heat.

Frequently asked Questions

The LOFI wood stove (and speed controller) weighs in at under 150grams!

No, the LOFI stove is cool to the touch on the bottom, below the lower air vents.  I’ve often used the stove on wooden picnic tables and grass, it leaves no trace (LNT).

Even outdoors and in a slight breeze, the LOFI stove is 75% as efficient as a gas stove hob running in your home! (watch the YouTube video)

The stove will burn most solid Biofuels, this includes wood & sticks, wood pellets, charcoal. We’ve even used Corn chips, Noodles, and sheep’s poop for cook food on at a push! (Check out YouTube for some video examples!)

Paper and card other tinder can be used to start fires. Do not burn liquid fuels, gas or plastics in the stove.

The stove is 90mm Diameter and 106mm tall.

All the electronic components have been coated in an additional protective silicone coating to provide reliability in even the toughest conditions, if the stove gets wet just dry it off. The speed controller is rated to IP67 (up to 1 m of water submersion).

No, the stove is powered by a USB battery bank. It only uses a small amount of power (0.5amp max) to force the air through the wood fire, but cannot charge a phone.

The stove will use 0.055amps on the lowest setting, to 0.5amps maximum on high power.

A 10,000mAh battery pack will last between 150 hours on low, or 15 hours on full power.

  • A 10,000mAh battery pack will last between 150 hours on low, or 15 hours on full power.
  • A 5,000mAh battery pack will last between 75 hours on low, or 7.5 hours on full power.
  • A 3,350mAh battery pack will last between 50 hours on low, or 5 hours on full power.

As the stove uses so little power, it can be left running until the fuel has run out or;

Where ground fire is not a risk, the fire can be tipped and snuffed/or water poured onto it. If you are in areas with dry vegetation please pour a cap full (15ml) of water into the stove to put out the fire.

The stove can be lit in the same way you light any small fire. For convenience I use 10ml (teaspoon) of bio-alcohol/meths onto the pellets, though fatwood, firelighters, flint and steel, char-cloth etc… can be used.

No, the powerpack provides airflow which keeps the electronics cool enough to function. Without this airflow the stove would be damaged.

The power banks last for many hours so this is unlikely, however if the power is cut please extinguish the stove with a cap full of water (15ml) to protect it.

The LOFI stove will work with a standard USB-C cable, however at full power only with no control. New cables will be available from my web-shop.

Yes, the stove contains no flammable fuels, you can fly with this stove. All pocked sized battery banks are also allowed on planes.
