Regulated mods are vape devices with an LED screen with adjustable wattage and safety features like short circuit protection and protection against putting your batteries in the wrong way. They will read new coils you install in your tank and allow you to set them on your device. Regulated mods can be run with subohm tanks and RDA RTA RDTA tanks. You can purchuse regulated mods on their own or in a kit with a tank included but will not come with batteries. These devices are the next step up from a starter kit and usually require 2 batteries and have a wattage range of 200+ and vary from mid to high end quality.
