Product Out of stock

If you’re looking for a cooler-drawing vape with a great flavour profile and lots of customization options, the Theorem from Wismec is the rig for you. The Theorem comes standard with the NotchCoil and dual adjustable airflow controls, giving ultimate control of the volume and velocity of airflow for a clean, consistent vape. Just about anyone can find the vape they like simply by changing the airflow settings; whether you’re an ex-smoker long accustomed to a mouth-to-lung draw, or a veteran vaper in search of a clean direct lung hit, the Theorem has customizable setting for you.

Made from high quality stainless steel, the Theorem is lightweight and durable, and its innovative top filling ensures an easy fill without any mess. Since the Theorem has a tank, technically it’s an RTA however this rig has a bit of the feel and taste of a dripper, producing a thick, powerful flavour. The large vape chamber and the indirect air feed produce a cooler draw that’s strong on taste and always a pleasure to inhale.

Though the Theorem is compatible with a wide variety of coils on the market, it comes standard with a NotchCoil for a reason. Certainly a great tank in its own right, it really shines when paired with the extra surface area of the NotchCoil; coupling this surface area with the Theorem’s voluminous chamber creates a compelling vapour profile that doesn’t need tampering with.

If you’re looking for an RTA with complete airflow control and an impactful taste, the Theorem is a powerful choice that packs strong flavour and limitless customization. Sure to please any enthusiast, the airflow, versatility, and control of the Wismec Theorem places it amongst the elite of the RTAs on the market today.

Sub-Ohm Vaping;

This vape tank is designed for sub-ohm vaping. Sub-ohm tanks require more experience to use safely and care should be taken when using a sub-ohm tank. The sub-ohm coils will only fire with a mod capable of sub-ohm vaping, the mod will state in the specification that it has a range below 1.0ohm. Nickel (Ni200) coils will only fire with a mod that states it has temperature control (TC) mode. Please ensure you use batteries that can handle the extra power required and your mod can handle the extra amps.
We would also advise that you do not use e-liquid with more than 6mg as sub-ohm tanks give a greater throat hit and will create more vapor to be inhaled.
