SKYHOOK: The SMOK Skyhook RDTA Box 220W All In One System is a revolutionary new system backed by one the strongest brands in the industry, designed off of the critically acclaimed Alien 220W Box Mod, packing in a tremendous 9ml tank reservoir, ultra sophisticated output, and a versatile two post RDTA deck. Intended as the ultimate in all in one systems, the Skyhook is fundamentally grounded in design from the SMOK Alien 220W, maintaining the same principle style and design language. SMOK has utilized extensive restructuring to only marginally increase the width while integrating a massive 9ml integrated tank reservoir, a true feat in design and engineering. The 9ml tank reservoir is filled via a dedicated threaded cap measuring 15mm in diameter, allowing users to very quickly fill the reservoir to maximum capacity. The RDTA section directly accesses the Skyhook's reservoir, featuring a stacked two post design with each terminal measuring 3mm by 2mm, giving it tremendous versatility. The airflow system is also extensive, with six adjustable side airslots and dual bottom airslots that provide tremendous maximum airflow. The Skyhook utilizes the most advanced two battery powered SMOK display and chipset to date, with a range of 6 to 220W, three output modes, and full temperature control, driven by two high amperage 18650 batteries (sold separately) run in series. The Skyhook also integrates a squeeze to fire mechanism, allowing for the complete showcase of the industry leading OLED screen. With a display matrix that features a six line and three column display, the OLED screen is unique in that it natively shows each batteries state and life individually, with incredibly rich data feedback overall. Positioning itself as the marquee all in one system to date that combines the beloved design and output of the Alien 220W with a 9ml tank reservoir, the SMOK Skyhook RDTA Box 220W All In One Kit is this year's must have system for any enthusiast.
