Quick Summary Of The iStick i40

The portable iStick i40 box mod features 40 watts of variable power, a 2600mAh internal cell, a charging system, a variable voltage mode, a variable wattage mode, and a screen to make settings changes.  The kit includes the D20 Tank with a 3mL juice capacity, a top-filling configuration, an adjustable airflow ring, and easy coil replacement.

Box Mod Design & Overview

The iStick i40 is tiny, reminiscent of the iStick 40W, and the appearance is simple yet gorgeous thanks to 5 incredible colors: black, greenery, fuchsia pink, neon orange, and cyan.

The mod has an ergonomic shape and leather handle, making it comfortable to carry anywhere.  On the control face is a classic monochrome display screen with horizontal UI for easy adjustments or changing the mode.

With a maximum output of 40 watts from a massive 2600mAh battery, the i40 will continue operating all day without a recharge.  Best of all, the 2 adjustment buttons underneath the UI allow you to set the mode to either variable voltage or wattage.
