Vapefly Siegfried Mod is a compact tube mod that designed by German 103 & Vapefly, with a maximum diameter of 25.2mm, perfectly matching Siegfried Mesh RTA, and also suitable for other atomizers. Siegfried tube mod has a high-quality process, forged and polished from the best quality stainless steel. After careful CNC processing, with a dragon-shaped carving pattern, it is in line with ergonomics and has an excellent hand feel. Vapefly Siegfried Mod is powered by a single 20700 or 21700 battery. It can be compatible with 18650 batteries using the included 18650 battery adapter.  The LED above the fire button can quickly and easily read the battery level. The Siegfried Tube Mod will transfer the power provided to it in bypass mode to the connected tank and the coil used. This means that the power output depends on the coil resistance used and the current-voltage of the battery cell used. The core of Siegfried Mod is Vapefly's modern 3S chipset. This is also the main difference between Siegfried Tube Mod and pure mechanical mod. The chipset has a nano-coating to prevent the penetration of water, moisture, and liquids, and always reliably and safely monitor the work of the Siegfried Mod.
