DOVPO Topside 90W Squonk Mod is made in collaboration with The Vapour Chronicles, deploying the first top-fill squonk mod  design with 10mL max capacity, single 21700/20700/18650 platform, and an intelligent chipset with BYPASS and optional Temperature Control. The DOVPO Topside 90W is created from Zinc Alloy and Aluminium Alloy to make it moderately impact-resistant in an ergonomic shape, with parts that have contact with eLiquid are made from food-grade Stainless Steel and silicone. The Topside has a single battery bay for a high-amp 21700 battery (sold separately) while leaving space for a 10mL squonk bottle adjacent for today's popular eJuice. Within the unit, the squonk bottle can be filled from the top, after unscrewing a knurled and threaded top cap. The squonking action on the Topside Box mod is found opposite of the firing button and display face and is made from food-grade silicone for a truly unique design. The leak-resistant 510 base is useful that it will not allow juice within the internals. Furthermore, the 510 base is gold-plated and spring-loaded for the best possible conductivity
