The Zpoo lighter primarily uses a type of lighter fluid known as butane. This is a common choice for portable lighters due to its ease of ignition and relatively low flammability compared to other fuels. Butane is a hydrocarbon gas that is odorless and colorless, making it suitable for use in lighters as it can be easily ignited with a spark.

The preference for butane in the Zpoo lighter is due to several factors. Firstly, butane has a high energy content, which means it can produce a consistent flame for various applications, such as lighting cigarettes, cigars, or campfires. Secondly, butane is relatively safe to use because it has a low flash point, which is the temperature at which a substance can ignite. This makes it less likely to ignite accidentally, reducing the risk of fire-related accidents. Additionally, butane is widely available and can be found at most convenience stores, making it convenient for users to replenish their lighter fluid.

According to a report by the U.S. Energy Information Administration (EIA), butane is the most commonly used fuel for portable lighters in the United States. The EIA states that butane accounts for approximately 80% of the lighter fuel market in the country. This widespread use of butane is due to its favorable properties and the convenience it offers to consumers. The report also highlights that butane is a byproduct of natural gas processing and crude oil refining, making it a readily available and cost-effective fuel option.

In conclusion, the Zpoo lighter uses butane as its primary fuel due to its high energy content, low flammability, and widespread availability. The choice of butane is supported by industry data, which indicates its dominance in the lighter fuel market in the United States.
