Bushcraft - EDCBox Micro Stove

The perfect little gift for real men! Our EDCBox is the world's smallest hobo stove, and with a packed size of 4.7 x 6.5 cm and a weight of 75 grams, it can truly be stored anywhere—even in a wallet or on a keychain. At the same time, it is a full-fledged hobo stove that can be fueled with natural wood (e.g., spruce twigs), but also with a spirit burner, Esbit, fuel paste, or a tea light. It has also been used as a pen holder, a stylish office coffee cup warmer, or an atmospheric bushcraft tea light lantern. The EDCBox is a design by Volker from Franken-Trekking and is manufactured in Germany from stainless steel (1.4301). Each part of the hobo stove has a hole for a carabiner.

By the way: the little one is also popular with the ladies and is often "repurposed."

Technical Data Packed size: 4.7 x 6.5 cm (6.8 x 11 cm in the pouch) when folded (with a thickness of 0.8 cm). When set up for use, the EDCBox has a height of 6.5 cm with a side length of 4.2 cm. The weight is 75g (81g with the pouch). Material: stainless steel (0.8 mm material thickness, 1.4301). The scope of delivery includes a sturdy pouch with a Velcro fastener. OTHER PRODUCTS SHOWN ARE FOR ILLUSTRATION PURPOSES AND ARE NOT PART OF THE OFFER.

Notes on Hobo Stove Firing

Soot/Smoke: Soot formation always means: lack of oxygen and too low a combustion temperature. When fired correctly, no significant soot can form in a Bushbox XL or a Bushbox LF. Soot and smoke are always signs of incorrect firing.

Chimney Effect: The basic principle of a hobo stove is the chimney effect; our stoves are also built so that the Coanda effect can better come into play. Both physical effects require that air supply is ensured, creating an air flow that supplies oxygen, which on one hand allows very high temperatures to be reached (up to 800 degrees) and at the same time (and this is the most important point) the heat is channeled upwards by the air flow and reaches the pot almost completely, instead of radiating out the sides.

Optimal Operation: A hobo stove is operated optimally when there is comparatively little fuel in the combustion chamber. The wood then burns very hot, the heat is only partially transferred to the outer walls, smoke and soot cannot form (if soot does form, it burns off without residue), and almost no warping occurs because there is no localized heating of the side walls. If the hobo stove has been fired optimally, there is also almost no residue or ash, just a tiny pile of very light, almost white ash.

Care should also be taken to avoid "yo-yo heating" (constantly changing temperatures) and extreme temperature differences (quenching in cold water).

In very many of the videos circulating on the internet, however, the boxes are stuffed to the brim, and you can sometimes see a meter-high flame shooting out of the hobo stove. But this leads to the following problems: The chimney effect is severely restricted, the combustion temperature drops to around 200-300 degrees, and smoke and soot are produced. Burning material touches the side walls in many places, which leads to strongly uneven heating of the side walls and simultaneously to the transfer of a lot of energy to the side walls. Heat islands or a strong temperature gradient between the top and bottom occur, allowing another physical effect to develop optimally: warping.

Improper Use: Many misunderstandings also arise because some of our customers use the stoves as mobile campfires and expose them to hours of yo-yo heating and occasional over-firing. Our stoves must prove that they can withstand such things and still be folded or remain fully functional afterwards, but no normal steel survives this permanently without damage (any more than quenching in cold water does).

Warping: Warping is a physical phenomenon that is unavoidable when metal is heated unevenly (and therefore expands unevenly). Slight warping is therefore inevitable and normal. However, all our hobo stoves are designed so that warping only occurs to a very moderate extent when used as intended and the function of the hobo stove is in no way impaired.
