One of the most popular new atomizers on the market, the 454 Big Block RDA from Kryptonite Vapor is big on vapor production, and crammed full of features designed to satisfy the needs of even the most demanding vapers. Featuring up to 4-way airflow control and an innovative grounding ring, this RDA is perfect for just about any type of build.

The 454 Big Block is a 22mm rebuildable dripping atomizer featuring an innovative 6-piece design that includes a 2-piece barrel for adjustable airflow, an air cooled fin-based top cap, a 5-post deck with extra deep juice wells, a negative grounding ring, and a Delrin drip tip with side-drilled holes to prevent juice splashing, making the 454 Big Block unlike any other atomizer we sell. The 2-piece barrel adjusts to accommodate airflow options that range from a single coil to a quad coil build, in both vertical or horizontal configurations. The center post has 4 holes in it, making it incredibly easy to build quad coil builds. The innovative grounding ring screws down to the deck, creating a negative connection anywhere on the deck and allowing for incredibly easy builds.

Each 454 Big Block RDA is made from stainless steel, comes with a Delrin drip tip, and is engraved with the Kryptonite Vapor logo, the 454 name, and MADE IN THE USA on the bottom of the deck.
