Designed in Germany, the eXpromizer V4 is a rebuildable tank atomizer developed for tight and flavor-focused MTL vaping with its single coil build deck, liquid control system, and top-to-bottom airflow routing.
The eXpromizer V4 is the fourth generation of the eXpromizer MTL RTA series developed by eXvape. Its 23 mm diameter stainless steel body provides a balanced look with compact mod devices, while the single coil deck structure helps build MTL coils easily.
Air is taken from the top section of the atomizer and directed beneath the coil via internal channels within the body. This top-to-bottom working structure helps reduce the risk of leaking compared to classic bottom-airflow RTA models and ensures the coil receives balanced airflow from underneath.
Thanks to the adjustable liquid control, the amount of e-liquid reaching the cotton can be adjusted based on the viscosity of the liquid used and the wicking setup. Closing the liquid control before top filling reduces the risk of flooding the deck chamber and causing gurgling.
Airflow and Liquid Control
Air taken from the top section is carried to the bottom of the coil through internal channels. This system aims to offer a tight MTL draw, balanced flavor delivery, and a structure better protected against leaking.
Liquid control helps adjust cotton wicking for liquids with different viscosities. The optimal setting may vary depending on the wire used, cotton amount, and the VG/PG ratio of the liquid.
Package contents may show minor variations depending on the production batch and regional packaging.
The eXpromizer V4 is not an atomizer that uses pre-made coils. Wire and cotton installation are done by the user. Resistance value and short-circuit checks must be performed before use, cotton must be completely saturated with liquid, and the safe amperage limits of the battery used must be taken into account. Users without sufficient knowledge of Ohm's law and battery safety are advised to seek support.
No. This model is a rebuildable RTA featuring a single coil deck structure. Wire and cotton installation are performed by the user.
The standard package has a 2 ml capacity. When using the compatible Bubble Glass or extension kit sold separately, the capacity can be increased up to 4 ml.
Yes. Closing the liquid control before filling helps reduce the risk of flooding the vaporization chamber and causing gurgling. The appropriate feeding adjustment should be reopened after filling.
The top air intake helps reduce the risk of leaking, but incorrect wicking, excessive liquid feeding, or faulty setup can cause gurgling and liquid overflowing.
