Uwell Valyrian 2 Pro Tank is optimized and upgraded based on its predecessor Valyrian 2 sub-ohm tank, which is mainly reflected in the following aspects: increase diameter; expanded air passage to increase airflow inflow; use 810 drip tip; increase e-juice capacity; optimize flip top cap, and can provide the production of a larger amount of clouds. Valyrian 2 Pro Tank is made of mildly impact-resistant stainless steel and heat-resistant glass to maintain durability. Valyrian 2 Pro Tank uses XL large-capacity drum-shaped glass tubes to provide high-end players with a long-lasting supply of e-juice, and there is no need to frequently inject e-juice when enjoying the dense cloud. At the top of the Valyrian 2 Pro Tank is an 810 drip tip, just below which you find a small flip cap button. To fill the tank, simply press the button and the top section will pop up to reveal two large filling holes, so you can fill the tank through one hole while air is released through the other. The clamshell structure has been optimized and upgraded, and the opening angle is larger. Flip-open cap can be opened with more ease with just one hand at a greater opening angle. Comes with two different mesh coils, with one having a resistance level of 0.14 ohms while the other has a resistance level of 0.32 ohms. Both utilize mesh material to ensure a more even and satisfying vape overall. You can also choose UN2 other coil options. The coil head itself possesses wide inset e-juice holes making for a quick and easy saturation process. Valyrian 2 Pro Tank adopts an innovative self-cleaning coil system that ensures that the condensation that's produced with each hit goes back into the coil, preventing flooding. Valyrian 2 Pro Tank also adopts the brand's famous Pro-FOCS Flavor Tasting Technology. To make your vaping unique, Uwell is dedicated to reviving the juice's flavor by controlling the heat of the coil, the quality of the coil, and the air dynamics of the flow.
