SMOK TFV8 Big Baby Beast Review | SMOK Big Baby Beast Review

The SMOK TFV8 Big Baby Beast is a highly anticipated sub-ohm tank that builds on the immense success of its smaller predecessor, the TFV8 Baby Beast. While maintaining compatibility with the same coil family, the Big Baby Beast significantly enhances the vaping experience by offering a larger e-liquid capacity and optimized airflow, making it a compelling option for vapers who love dense clouds and rich flavor.

Originally reviewed in January 2017 by Julia Barnes, this tank quickly became a favorite among sub-ohm enthusiasts. It positions itself as a sweet spot between the compact Baby Beast and the behemoth TFV8 Cloud Beast, providing ample e-liquid storage without being overly cumbersome. If you’re looking for a tank that delivers consistent performance, excellent flavor, and impressive vapor production, the Big Baby Beast is certainly worth considering.

About the SMOK TFV8 Big Baby Beast

The Big Baby Beast is a sub-ohm tank designed for versatility and performance. It features a 24.5mm diameter, slightly larger than the Baby Beast, which accommodates its increased 5ml e-liquid capacity. Crafted from high-quality stainless steel and pyrex glass, it boasts a robust build. The tank retains SMOK’s signature hinged top-fill system, making refills quick, clean, and convenient.

One of the Big Baby Beast’s key advantages is its compatibility with the popular TFV8 Baby Beast coil line. This means vapers have a wide range of coil options, from flavor-centric dual coils to cloud-chasing sextuple coils, allowing for a personalized vaping experience. The wider diameter also allows for slightly larger airflow slots compared to its smaller sibling, contributing to even more efficient vapor production and cooler draws.

Performance Review

The true measure of any tank lies in its performance, and the Big Baby Beast truly shines in this regard. Here’s a breakdown of its key performance aspects:

Flavor Production

The Big Baby Beast delivers exceptional flavor, which is a hallmark of the TFV8 series. With the right coil, especially the V8 Baby-X4, e-liquids come through crisp and clear, allowing you to discern subtle notes. The slightly increased internal space and optimized airflow contribute to a rich and satisfying flavor profile that rivals many larger tanks.

Vapor Production

For a tank of its size, the vapor production from the Big Baby Beast is impressive. It can churn out dense, voluminous clouds that will satisfy even seasoned cloud chasers. The ample airflow and efficient coil designs work in tandem to create a truly enjoyable cloud experience.

Airflow and Draw

The dual adjustable airflow slots at the base of the tank are smooth and easy to manipulate. You can dial it in for a wide-open, airy draw perfect for massive clouds, or restrict it slightly for a warmer, more concentrated flavor. The draw itself is smooth with minimal turbulence, making for a comfortable vaping experience.

Coil Longevity

Coil life is always dependent on usage habits and e-liquid type, but the Big Baby Beast coils generally offer decent longevity. Users can typically expect 1 to 2 weeks of consistent performance from a single coil, which is competitive for sub-ohm tanks in this category.

Top-Fill System

SMOK’s hinged top-fill design continues to be one of the best in the industry. It’s incredibly convenient – simply swivel the top cap open, fill the kidney-shaped port, and swivel it back. It effectively prevents leaks and makes on-the-go refilling a breeze.

Coil Family Deep Dive

The TFV8 Baby Beast coil family is a cornerstone of the Big Baby Beast’s versatility. Each coil head offers a unique vaping experience:

V8 Baby-X4 Quadruple Coil (0.15ohm)

This coil is often considered the workhorse for balanced performance. Operating best between 45-60W, it strikes an excellent balance between intense flavor and respectable vapor production. If you want to experience your e-liquids to their fullest, this is a fantastic choice.

V8 Baby-T6 Sextuple Coil (0.2ohm)

For those who prioritize vapor, the T6 coil delivers. Best used between 70-90W, it produces massive clouds without significantly sacrificing flavor. It’s a great option for cloud competitions or simply enjoying a dense vapor experience.

V8 Baby-Q2 Dual Coil (0.4ohm)

The Q2 coil is ideal for vapers looking for a slightly cooler vape, longer battery life, or those using lower wattage devices. With a best performance range of 55-65W, it still provides good flavor and a satisfying amount of vapor, making it a versatile everyday coil.

V8 Baby RBA (Optional)

For the DIY enthusiast, the optional V8 Baby RBA head allows you to build and customize your own coils. This offers unparalleled control over your vaping experience, allowing for fine-tuning of resistance, wicking, and coil material to perfectly match your preferences. While not included in the standard kit, it’s a valuable addition for advanced users.
