The Uwell D1 Sub-Ohm Tank is the pinnacle of truly leak-proof design within a competitive Sub-Ohm market, featuring an anti-leaking installation with condensation protective design, double-glass top airflow system, 4mL juice reservoir with threaded top-fill, and the introduction of top-loaded D1 Coil Technology. The chassis of the Uwell D1 Tank measures 24.7mm in diameter at the base, integrating a refined anti-leaking, cupped-inspired design with condensation protection. The anti-condensation has been implemented into the base to relieve back pressure and virtually eliminate possible flooding. Built for a performance orientated structure, the Uwell D1 implement a unique airflow delivery system of its kind with double-glass airflow with three hidden airslots. The air channel enters through the adjustable airslots at the top cap, which are then funneled down between the two glass tubes to create an effective passage to the atomizer base, providing an unprecedented vapor production while retaining a flavor-enhance experience. The 4 milliliter maximum tank capacity is filled with a threaded top-fill system with deep fill ports, further minimizing juice spillage. The new coil family utilized with the D1 Tank have been designed with convenience and ample performance in mind, featuring the premade coil unified with the top tank section instead of the base, resulting in simple coil changing without emptying the tank. You can change the coil by unscrewing the condensate base holder for direct access to the atomizer core. Working in synergy with the new leak-proof structure and utilizing the innovative airflow system, air channel guides into the D1 Coil Technology , providing smooth airflow through the entire apparatus. The D1 Parallel Coil structure is the continuation of the Uwell Crown II, focusing on mid-level wattage output and keeping the wattage range similar to Uwell's performance line-up. The 0.25ohm SS316 Parallel Coil has a recommended range of 50 to 8-W, while the 0.5ohm is rated for 40 to 60W. New is the introduction of 0.8ohm Kanthal Parallel Coil, with optimal output between 35 and 55W, catering to traditional heating element. With a truly unique and perfect execution of Uwell's pristine design and manufacturing prowess, the Uwell D1 Sub-Ohm Tank is the evolution of midwattage systems in the industry.
