Understanding the Different Types of WEQTETJU Lighters

It seems like you're asking about different types of lighters, but the word "WEQTETJU" doesn't appear to be a real word related to lighters. Could you please clarify what you're looking for?

For example, are you interested in:

* Types of Lighter Mechanisms: (e.g., flint wheel, piezoelectric, electronic)

* Fuel Types: (e.g., butane, propane, kerosene, naphtha)

* Lighter Styles: (e.g., Zippo, Bic, torch, pipe lighters)

* Specific Brands of Lighters: (e.g., Ronson, Colibri, Dunhill)

Once you provide me with more information, I can help you understand the different types of lighters you're interested in.
