Integrating an updated postless build deck with four terminal openings to accommodate single or dual coils while maintaining the dynamic, leak-proof top airflow design. Now measuring in 26mm in diameter, the Zeus Dual RTA maintains all the creative headlined by the ergonomic top-fill, top airflow structure. The maximum eJuice capacity is 4mL, accessed via a threaded top-fill method. The user-friendly postless build deck implements four terminal openings, capable of handling creative single or dual coil configurations. The airflow channels are optimized for flavor and vapor production, entering through the two external top airslots that travels downward to the atomizer base. Then, it redirects into two internal side slots and across the coil chamber before rising vertically through the wide chimney. Furthermore, the Zeus Dual includes an 810 Delrin widebore drip tip with the optional 510 Delrin widebore drip tip and 510 drip tip adapter for extended versatility.
