UWell Crown 4 Checkmate 200W TC Starter Kit Box Mod Sub Ohm Tank Combo


UWell Crown 4 Checkmate 200W Starter Kit


UWell Crown 4 Checkmate 200W Starter Kit

The Crown 4 "Checkmate" kit from UWell is a combination of the Crown 4 tank and an elegant, easy to use, dual flat-top 18650 box mod utilizing UWell's proprietary chipset capable of 200W maximum output.

The Crown 4 box mod features a new circuit board design from UWell, featuring resistance to dust and corrosion, helping to extend the life of the product. The proprietary chipset offers an output range of 5 to 200W, and reads an atomizer resistance range of 0.1 to 3.0 Ohms when used in "POW" (wattage) mode. Its temperature control suite allows for SS304 and Ni200 heating wire preferences, while offering a TCR mode for use of temperature coefficient ranges. Within the temperature control suite is also an SS904 mode which is meant to be paired with the SS904 coils available for the flagship Crown 4 sub ohm tank. An OLED screen shows the user an assortment of pertinent vaping data such as output wattage, battery life, and atomizer resistance. 

The Crown 4 Sub Ohm Tank from UWell features a 6mL capacity and a top fill design. A 28mm diameter base with dual adjustable airflow slots allows the user to dial-in their preferred airflow with precision. Similar to the Crown 3 tank, the Crown 4 employs the threadless plug-pull design coil head for quick and convenient coil replacement, and are available in several different resistances and materials: 0.2 Ohm dual SS904L, 0.4 Ohm dual SS90L, 0.25 Ohm SS304 UN1, and 0.23 Ohm FeCrAl UN2. The Crown 4 coils use organic cotton for wicking, feature a vertical coil design, and use 3 o-rings to ensure a tight seal in your Crown 4 Tank.
