Vaporesso’s Cascade sub-ohm tank holds a whopping 7ml of e-juice and is 24mm in diameter. They named it “cascade” probably because the e-juice flows down under the coils in unique fashion.
It features an “isolation structure” design that separates the coil from the juice chamber. This is designed to produce a consistent intense flavor and reduces dry-hit potential. It comes in stainless steel, matte black, sapphire blue, and rainbow, with an option to add on different color glass tubes for extra customization.
The reviewer in the video below analyzes the Cascade sub-ohm tank’s features and gives an overall opinion on its efficiency. We learn that the glass tube is 28mm in diameter, which is able to hold the 7ml of e-juice. It also is capable of wattage ranging from 25-200.
The method of changing coils is very simple and you can do so without wasting any liquid that may still be left inside the tank. You can swap coils even when the tank if full. The Cascade sub-ohm tank includes two different coils, which is a major plus. She points out that depending on what coil is used and on a higher wattage, it can be an e-juice guzzler.
