UWELL Valyrian 3 Starter Kitfeatures a new-generation printed circuit board assembly. What is even more fascinating is that you can even feel the "dragon" with its throbbing pulse and the breathing from its 5 LED breathing lights, which is equivalent to the dragon's back. It utilizes a 0.96-inch color screen to monitor your kit and can automatically detect your atomizer resistance. It delivers extreme and enduring use because it is powered by dual 18650 batteries (not included) coupled with max 200W output. Paired with Valyrian 3 Tank and Valyrian 3 Coils.
