The Kick by Smok Tech
The Kick is a power booster for your 3.7V mod. It works great and
gives you numerous options from increasing power to the cartomizer or
clearomizer you currently use to allowing you to use a higher resistance
cartomizer or clearomizer.
The Kick is designed to take a standard 3.7 Volt Battery and boost
the power. It operates in a range of 3 to 12 Watts. Only use IMR
batteries with The Kick. For a mod that normally takes an 18650 battery,
an 18500 should be used with this device. The Kick is for use with
metal mods only.
