The iStick 30W by Eleaf is a well improved version over its predecessor. Capable of firing 30 watts and firing down to 0.4O, the iStick 30W looks and performs very similar to the previous version, but better! Variable voltage settings go from 2 volts and tops out at 8 volts, giving the user a wide range of power within the limits of the device. The 510 connection is now spring loaded, allowing for a better contact to your 510 atomizers. The updated design of the iStick 30W incorporates a 22mm lip surrounding the stainless steel threaded 510 connection for a more flushed look with your 22mm atomizers.
