The DOVPO Topside 90W Squonk Mod is the first top-fill squonk mod  design with 10mL max capacity, single 21700 platform, and an intelligent chipset with BYPASS and optional Temperature Control. The DOVPO Topside 90W is created from Zinc Alloy and Aluminum 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. 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.
