The iStick TC40W is everything you could ever want out of a basic vape battery. A perfect fit for older 510 or eGo threaded vape atomizers. Also works wonderfully as an adjustable power device for cannabis/THC extract cartridges as the connector provides the airflow slots needed for those atomizers.
Output from 1W-40W to accomodate a wide range of atomizers.
For use with extra cartridges we advise around 5W to 7W. Using the voltage display on the bottom left of the screen, try to keep the voltage between 2.8V to 3.2V when firing.
