No, not all portable gas stoves have a separate fuel tank on top. Portable gas stoves come in various designs and fuel types, and the fuel storage method can differ accordingly. Here are some common types of portable gas stoves and their fuel storage setups:
Propane Stoves: These stoves typically have a separate propane tank that attaches to the stove. The propane tank can be placed on the ground or a stable surface beside the stove and connected to it via a hose or built-in regulator.
Butane Stoves: Some portable gas stoves use butane canisters as their fuel source. These stoves often have a built-in compartment or holder where the butane canister is directly connected.
Isobutane Stoves: Similar to butane stoves, isobutane stoves use isobutane canisters as fuel. The canister may be connected directly to the stove or housed in a specific compartment.
Liquid Fuel Stoves: These stoves can use various liquid fuels, such as white gas (also known as Coleman fuel), kerosene, or unleaded gasoline. They typically have an integrated fuel tank or bottle that is attached directly to the stove.
Wood-Burning Stoves: Some portable stoves are designed to burn wood as fuel. They do not require any separate fuel tank; you simply place small pieces of wood or biomass into the stove's combustion chamber.
Solid Fuel Stoves: These stoves use solid fuel tablets or cubes, which are placed on a tray or platform within the stove.
The design and fuel storage method can vary between different brands and models of portable gas stoves. It's essential to read the product description or user manual for the specific stove you have to understand its fuel requirements and usage.
