The burner is capable of boiling water and heating rehydrated food, it has a capacity of 20 ml of fuel. The Mini Burner has the same wadding as its larger Screw UTD Burner brother and uses Ethanol/Methanol/Methylated Spirits as fuel sources. Weighing a measly 6.5g it is ideal for a brew up when paired with a Short Cone and 400ml pot. Spillproof and leakproof, screwtop lid with gasket. Remember to remove the lid gasket when using as a stove jack.
