Detailed Product Description

1,Mechanical design and CNC machined

Made by stainless steel,and Mechanial desiged and CNC manchined without any PCB board inside the body tube,so is much more durable and lifespan is much longer.

2,No PCB board to avoid short circuit and breakdown
use no PCB board inside of inner battery tube,to off high quality durable vaporizer mod,there will no short circuit and breakdown happened,no liftspan limitation.

3,You can also adjust the battery spring by screwing it left or right to raise or lower the height of the spring to accommodate your batteries.

4,Multi-choices for various kind of batteries and voltages
Compatible with various kinds of batteries for different length.
Below it is the list of battery cups and batteries,also different voltages to work with different resistance atomizer

Fit with 18350,18650,
Short cup only:1x18350,3.7v ,fit regular or low resistance atomizer
short cup+ extend cup:1x18650,3.7v ,fit regular or low resistance atomizer
short cup+extend cup:2x18350,6v ,fit high resistance atomizer

Warning:Be especially careful with this as voltage will be what you put into it,don't recommend ever stacking batteries,you can easily below out a atomizer/clearomizer/cartomizer!

5,Compatible with various kinds of atomizer
Compatible with all 510 male threading atomizer,
cartomizers and clearomizer,vivi nova,v-core.CE4.CE5

6,The deco rings(Made by aluminium,can be disassembled)
