The Kanger TOPBOX Mini Starter Kit is a great way to experience Temperature Controlled Sub-Ohm vaping with up to 75 watts of power, whether you prefer to wrap your own coils or simply purchase pre-built coils for convenience. The Kanger TOPBOX Mini Starter Kit includes the popular KBOX Mini TC-75 and TOPTANK Mini (4.0ml) to create the ultimate combination of form and function in a single starter kit. The TOPTANK Mini holds 4ml of your favorite e-juice and features a new top "fill design" that makes it much easier to fill your tank without requiring it to be disassembled or drained. Simply unscrew the top part of the TOPTANK Mini and fill through the slot until the tank is full, then replace the top cap and hand tighten. Note: The TOPTANK can also be filled from the bottom as well. The Kanger TOPBOX Mini Starter Kit includes three Stainless Steel Organic Cotton Coils (Ni200 0.15 ohms), (Clapton 0.5 ohms), (SSOCC 0.5 ohms), and one RBA Head for those who want to wrap their own coils. Kanger also offers Atomizer Heads with higher resistances for those who prefer "mouth to lung" inhales (1.2 ohms & 1.5 ohms) that are sold separately. The KBOX Mini TC-75 is powered by a single replaceable 18650 battery (not included) and supports Nickel, Titanium, Stainless Steel, and Nichrome coils in Temperature Control Mode along with Kanthal coils in VW Mode. The KBOX Mini TC-75 can fire atomizers down to 0.1 ohms with a rated output from 7 - 70 watts and features Micro USB Charging, Spring Loaded 510 Connector, OLED Display, and Short Circuit Protection. The KBOX Mini TC-75 is constructed out of High Grade Stainless Steel and is built to last "day to day" use while providing great vapor production and flavor.
