The lightest KOVEA stove we provide is the KOVEA Titanium SupaLite. It weighs just 56g (less than 2oz). KOVEA Titanium Supalite (56g) is one of the lightest gas stoves you can buy.
The SupaLite has a low emission burner, and uses only 4-5g of fuel to boil 500ml (2 cups) of water. Boil time is around 2.5 to 3 minutes.
The burner produces a unique wide flame pattern. The flame shape set’s it apart from other ultralight stoves and is good for heating and cooking on larger pots. The regulator and valve are sensitive enough to simmer and lightly fry without hot-spotting. The regulator is glove-friendly. This also sets it apart from most other ultralight stoves.
See our video below of the KOVEA Supalite Titanium demonstrating how it can heat a wide pan, evenly and without hot spotting.

The KOVEA Titanium SupaLite (56g) KB-0707, is a tiny stove with big stove capabilities.
Here is one in Iceland using its wide pot supports to support a large 2.5 litre pot.
The glove-friendly regulator is ideal for cold weather usage, and the wide flame gives it both power for fast boiling and refinement for gourmet cooking.
Stove Weight In Context
But to put stove weight into context it is also worth noting that during 24 hours in the hills or on the trail you need to consume around 3-5 litres/kg of water. And you might eat 500g of food and snacks and in wet conditions you can easily accumulate 100g of mud on each boot and 300g of moisture in your clothes and tent. In relation to these, our customers generally agree that 10g or even 50g of extra stove weight is a small penalty for having a stove which has been designed for safety, reliability, performance and longevity.
MercatorGear does make an incredibly light stove which we use for testing and calibration purposes:

The MercatorGear 10g Hobo Stove (left) weighs just 10g, and uses 16g of meths to boil 500ml of water in around 7-8 minutes. But it is not as durable, controllable, efficient, safe or fast as our KOVEA gas stoves. You can only really cook soup and noodles on it. It is made from beer cans kindly donated by FourPure Brewing Company. But as a stove for an occasional brew it’s an excellent bit of ultralight gear.
