Authentic Koopor Primus 300W TC Box Mod

Koopor Primus 300W (Authentic) – $38.97

The Koopor Primus is a beast of a device packing in 300 Watts of vaping power on 3 18650 batteries. While this thing looks huge, it’s actually not much bigger than a typical dual 18650 box. Besides the 300 watts, this thing is packing in all kinds of great features like a large screen that you can see without any issues. It has a magnetic battery door for easy access to the batteries, but it also slides into place for added security so it doesn’t pop off too easily. This Koopor Primus 300W box mod has temperature control like pretty much everything else, but I don’t think it has custom TCR values though.

You might think that this Koopor Primus 300W box mod looks kinda like a cheese grater, and I might have to agree with you. But SmokTech has intended this to resemble a transformer which it kinda does, and the name is cool especially for transformer fans. All those holes provide a ton of ventilation for this device though which is great. It has very low power consumption in standby mod, and other great features like a spring loaded 510 center pin. To bottom line this, I think the Koopor Primus 300W box mod is a great device with a ton of battery life, even if you never intend to use the 300 watts!
