The Tanker Extract Battery by Ooze Tanker - 650 MAh Flex Temp Pen Battery - features a thermal chamber that acts as a forcefield for glass or ceramic cartridges, providing protection against drops and falls, and while being stored in a bag or pocket. To turn on and off the battery, simply click the button 5 times. The 4 flex temp voltage options can be cycled through by clicking the button 3 times. For oil cartridges, it is recommended to use the lowest voltage level. If there is no vapor produced, gradually increase the voltage until optimal results are achieved.
