The SMOK KOOPOR Primus 300W TC Box Mod is powered by three 18650 batteries to create a revolutionary 300 watt maximum output. The chassis is made out of durable Zinc Alloy and can take quite a beating. The form factor and material give the device a very pleasant feel when held.

The adjustable TCR Mode allows the user to customize their experience to a whole new level of precision.

The OLED screen is huge, showing off all information very neatly. The chassis and output power make the SMOK KOOPOR Primus 300W TC Box Mod one of the simplest yet effective devices in the entire vape industry.
