The Bear features a 510 thread and works with most oil or extract cartridges, and the Lookah 510 wax carts, so it is a versatile option for vapers of all levels. The Bear vape battery delivers smooth and satisfying hits with every use. It has a resistance range of 0.7-5 Ohm and three preset voltages, 3.2V, 3.6V, and 3.9V. These voltages display through an LED on the Bear's cute face, which lights green, blue, or purple to show the setting.
