SmokTech Zmax Variable Power APV Extension Cap in Stainless Clearance Item
The Zmax extension cap for the Zmax Variable Power Mod extends the length of the Zmax tube, enough to allow for the use of 2 x 18350 IMR batteries.
It's also great to use as a replacement bottom cap for either device. This cap will fit both the regular size Zmax, as well as the Zmax Mini.
The ZMAX requires one 18650 IMR battery, or two high power 18350 IMR batteries, by using this extender cap. It will work with flat or button top IMR's and protected Li-Ion 16340 batteries.
Never use non-rechargeable batteries in this or any other e-cig device! Only use the recommended batteries for this unit, it's for your safety.
