Testing the PAX FOUR: What You Need to Know

PAX Labs was founded in 2007, shortly after the carbonizer was developed for electronic cigarettes. By 2012, the company released its first dry herb vaporizer. That was over a decade ago, and since then, the makers of PAX have been refining their craft by continuously improving their devices and building on the success of their original design.

Introducing the PAX FOUR, the latest iteration of PAX Labs’ dry herb vaporizer lineup. According to the PAX website, this is their most powerful device yet, specifically built for those who want strong performance and bold sessions. The PAX FOUR delivers impressive potency and thick vapor clouds, backed by a 50-minute battery life. It also features USB-C charging, a major upgrade from the original proprietary charger used in earlier models.

With up to 50% more vapor production compared to previous versions, the PAX FOUR positions itself as a high-powered option in the portable vaporizer space.

What really stands out about the PAX FOUR is its portability and ease of maintenance. Instead of carrying around a bong or pipe, you can take this compact device with you wherever you go. It’s designed specifically for dry herb, so concentrates or other materials shouldn’t be used with it. The oven system is intuitive and user-friendly, making it accessible for both beginners and experienced users.

Checking the battery is simple, just give the device a shake and it will indicate whether a charge is needed. The PAX FOUR also features four heat modes, each represented by a different colored petal. Purple delivers the lightest vapor, green is ideal for longer sessions, yellow offers rich and consistent flavor, and red provides maximum power for dense clouds. For safety, the device will automatically shut off if it exceeds 55°C.

Overall, the temperature control is precise and reliable, and something you simply don’t get with traditional methods like a bong or pipe. That level of control is what helps set the PAX FOUR apart as a modern, high-performance vaporizer.

PROTIP: Sip, don’t rip! Sipping the vapor allows the cannabinoids and terpenes to be extracted gradually, rather than combustion.

One important thing to note about the PAX FOUR, and dry herb vaporizers in general, is that they require a medium-fine grind. Unlike traditional bongs or pipes, vaporizers won’t perform at their best if the flower isn’t prepared properly. If the grind is too coarse, vapor production will be weak due to the larger pieces. If it’s too fine, you risk pulling small particles through the device, which can lead to a harsher, slightly burnt taste or even a clogged airpath.

In addition to grinding, proper packing is key to getting the best performance out of the PAX FOUR. It’s recommended to fill the chamber about 70–85% full, then lightly tamp it down with a packing tool to reduce any large air gaps. Overpacking can restrict airflow and negatively impact the extraction, so finding that balance is essential for having a positive vaporizer experience. 

Now, let’s compare the PAX FOUR to a few other dry herb vaporizers on the market.

Starting with the Venty Vaporizer, which retails for around $449 and is significantly more expensive than the PAX FOUR at roughly $250. The Venty offers an adjustable airflow dial for more customization, while the PAX FOUR relies on preset heat modes. However, the biggest difference, aside from price, is portability. The PAX FOUR is lighter and far more pocket-friendly, whereas the Venty is bulkier and less convenient for on-the-go use. For portability and value, the PAX FOUR comes out ahead here.

Finally, the Arizer Solo 3 (v2.0), which retails for around $299, sits closer to the PAX FOUR in both price and performance. Both devices deliver strong vapor quality, reliable battery life, and durable construction. The Solo 3 stands out with features like a session timer and adjustable session controls, giving users more feedback and customization. However, it tends to have more draw resistance, requiring stronger pulls. The PAX FOUR, on the other hand, offers a smoother and more effortless draw. Both are high-quality devices, and the better choice ultimately comes down to personal preference.

Overall, the PAX FOUR holds its own in a competitive market and proves that PAX Labs continues to refine and improve its lineup. It strikes a strong balance between power, portability, and ease of use, making it a great option for both newcomers and experienced users. While it may not have every advanced feature found in higher-end devices, its performance, design, and convenience make it a standout choice for everyday use.

If you’re looking for a reliable, portable dry herb vaporizer that delivers consistent results without overcomplicating the experience, the PAX FOUR is definitely worth considering.
