The SkyStar Revvo from Aspire is a sleek and stylish mod with 210W of available power pulled from two 18650 batteries (Sold Separately). The front of the device houses the beautiful 1.3 inch touchscreen and hidden fire button above it. The touchscreen features an easy to use menu system with the ability to switch between the multiple power modes and access the clock screensaver. Sitting on top of the center-positioned spring-loaded 510 pin is the Aspire Revvo Tank, a revolutionary tank that uses a stovetop-style Radial Coil that produces fantastic flavor and plenty of vapor. Not only does the Revvo use an innovative coil - Aspire has also created a brand new fill port. Simply insert the tip of your bottle into the mouthpiece of the Revvo, push down on the spring loaded pin, and fill!
