The iStick 100W TC Box Mod from Eleaf is an updated version of Eleaf's famous iStick 100W. This model introduces Temperature Control functions and a range of 1 - 100W and will fire down to 0.1ohm. The iStick 100W TC Box Mod supports Ni200 Nickel, Titanium, and 316 Stainless Steel coil heads and features a 3 memory adjustable TCR mode that allow for even more precise Temperature Control. The new design of this device runs concurrently with the move toward a parallel powered chip set, giving the user flexibility to utilize a single 18650 battery for up to 75W or 2 batteries for 100W output. Eleaf has integrated the firing mechanism into one of the battery doors allowing for a more ergonomic and safe design. The Eleaf iStick 100W TC Box Mod is the perfect balance of power and functionality.
