Pros: The bottle is refillable, which is a bonus if you’re traveling to your hiking destination by air and want to bring your stove setup with you. Plus, you can use a variety of liquid fuels, which makes it easy to source fuel wherever you go.
Cons: Liquid fuels are heavy and less energy efficient than gas canisters. The stoves that use them are also harder to set up than stoves that use gas canisters.
Takeaway: Great for international trips because the empty fuel bottle can be brought onto an airplane and filled with fuel at your destination
