The Aspire SkyStar 210W TC Box Mod & Revvo 24mm Sub-Ohm Tank Vape Kit features a classy tank paired with a sleek box mod, offering elegant design with high wattage to create a truly beautiful power couple. First up, let??????s go over the box mod. Aspire has long been revered as a trendsetter and a groundbreaker in their designs, and that is certainly true when it comes to the SkyStar 210W TC Box Mod. As the name suggests, this mod shoots for the stars in terms of functionality and durability. The 1.3????? touch screen offers a smartphone-like experience, easy to navigate and simple to use. The chassis features a clean and crisp upright design that supports Kanthal, Titanium, Ni2000 Nickel, and Stainless Steel, along with 3 Memory Bank TCR support. As the name suggest, the device is has a max firing wattage of 210W, and is powered by two 18650 external batteries. Last yet not least, the device is equipped with CPS (Customizable Power Setting) Mode if you have a desire for even more customization within the settings. As with every great mod, there must be a great tank. The Revvo Sub-Ohm Tank slams a home run with tank pairings, featuring a triple set of adjustable airflow slots located at the top of the device for a leak-proof seal. Refills are quick and easy, thanks to the topfil spring-loaded design of the tank. And the designers of this tank weren??????t happy to settle with average, so they crafted an ARC (Aspire Radial Coil) Coil system, allowing for the implementation of mesh wires over a larger surface area. While this may all seem very technical, you can definitely feel the effects of this new system with enhanced vapor production and increased flavor throughout each and every puff. Each ARC coil can be replaced with the included ARC Mounting Screw, and has a range rating from 0.1 ohm and 0.16 ohm, meaning you should stick with a wattage anywhere from 50-100W for optimal results.
