Pax 2 — The Round Table

Overview

The Pax 2 is a portable, battery-powered dry herb vaporizer manufactured by PAX Labs (formerly Ploom), released in March 2015 as the successor to the original Pax vaporizer. It uses a conduction heating method, with the herb sitting directly in a heated stainless steel oven. The device is powered by an internal rechargeable lithium-ion battery and charges via a proprietary magnetic USB dock.

The Pax 2 was widely regarded within the vaporizer community as a significant refinement over the original Pax, offering a sleeker form factor, simplified mouthpiece design (eliminating the troublesome pop-up mouthpiece of its predecessor), and improved overall reliability. It quickly became one of the most recognizable portable vaporizers on the market, often described as the "iPhone of vapes" due to its minimalist industrial design and emphasis on ease of use. The community generally positioned it as a premier stealth and portability vaporizer, while acknowledging that it made trade-offs in areas such as vapor flavor, efficiency, and maintenance compared to competing devices.

Note on Warranty: There was some early confusion within the community regarding the Pax 2's warranty. One community member noted that the PAX Labs website initially appeared to show only a 90-day limited warranty for the Pax 2 while listing a 10-year warranty for the original Pax. This was eventually clarified — the Pax 2 carried the same 10-year warranty when purchased through authorized channels. Questions about international warranty coverage were also raised during the early pre-order period, as international availability initially lagged behind the US launch.

Community Reception

General Sentiment

The community's reception of the Pax 2 was nuanced. It was widely acknowledged as one of the best portable vaporizers available for stealth and portability, but it was never considered a top performer in categories like vapor quality, flavor, or efficiency. The device earned respect as a well-engineered consumer product but drew criticism from enthusiasts who prioritized extraction quality and taste.

One long-time community member who had hated the original Pax — citing its flavor, maintenance burden, efficiency, and price — returned to the Pax line with the Pax 3 and acknowledged significant improvements across the product family, suggesting the Pax 2 represented an important evolutionary step. Another member who had used Pax devices since 2013 described the community itself as an invaluable resource for getting the most out of the device.

Pros (as discussed by the community)

Exceptional portability and stealth: The slim, pocketable design was universally praised. One member noted "you barely notice it in your pocket" and that you could preload a bowl without needing a separate container.
Ease of use: Simple interface with four temperature settings and intuitive lip-sensing activation.
Motion-sensing standby: The device would stop heating when set down, conserving herb and battery. Community members appreciated this feature for reducing unintentional roasting of the load.
Build quality: Solid anodized aluminum construction that could withstand daily carry.
10-year warranty: Seen as a strong commitment from the manufacturer.
Good for sharing: The larger oven size (compared to many competing portables) made it suitable for group sessions.

Cons (as discussed by the community)

Flavor: The Pax 2 was generally not recommended when flavor was the primary concern. One well-known community member explicitly stated that "if flavour is important then the Pax is a poor choice." The conduction heating method and continuous oven cooking were cited as the primary reasons.
Maintenance requirements: The device required frequent cleaning to maintain proper function. This was a recurring concern, with one user noting that "the constant cleaning in order for it to work properly worries me."
Efficiency: The oven cooks the load continuously even between draws, which wastes material. A respected community member pointed out that "turning it on for a single hit is the worst way to use the Pax" because the oven never stops heating during operation.
Not a "big hitter": Multiple community members noted that the Pax 2 was "not a big hitter in terms of large clouds." It was described as a "great stealth vape" but not one that would satisfy users looking for dense, visible vapor production.
Conduction limitations: As a session-style conduction vaporizer, it was poorly suited to on-demand use patterns.
Odor: At least one community member noted that the Pax 2 was "pretty smelly," which somewhat undercut its stealth advantages.
Needed aftermarket accessories: Several community members felt the Pax 2 significantly benefited — or even required — third-party accessories (such as the NewVape Pax Pusher and 3D screen) to perform at its best.

Overall Position

The community generally agreed that the Pax 2 was best suited for users who prioritized portability, discretion, and ease of use above all else. It was frequently recommended as a "leave-the-house" vaporizer and was often suggested for users who needed a device they could take to social events, use in a car, or carry in a pocket at work. It was less commonly recommended for home use, where desktop or larger portable vaporizers were preferred.

Tips & Techniques

Grind Consistency

The community widely agreed that the Pax 2 performs best with a fine grind. A common recommendation was a two-stage grinding approach:

Use a standard four-piece grinder for an initial grind.

Follow up with a Magic Flight Finishing Grinder (MFFG) for a super-fine secondary grind.

Multiple community members confirmed this combination worked particularly well with the Pax 2. The fine grind increases surface area contact with the conduction oven walls, improving vapor production and extraction efficiency.

Oven Packing

Pack the oven firmly but not too tightly. The Pax 2's conduction heating works best when herb makes good contact with the oven walls.
For smaller loads, community members recommended using a Pax Pusher (from NewVape) to keep the herb compressed against the oven walls even when not filling the full chamber. One member specifically ordered a Pax 2 with a pusher "so that I can adjust amount in the oven and keep it compacted for a good smoke."
Degummed hemp fiber was suggested as an alternative method to reduce load size while maintaining proper oven packing. This allows users to fill the remaining space in the oven, keeping the herb compressed without wasting material.

Draw Technique

A well-known community reviewer reported testing various draw speeds on the Pax 2 and found no specific "sweet spot" needed — the device performed consistently across a range of draw speeds. However, the same reviewer noted that drawing very hard on the highest temperature setting could cause the device to drop into heating mode (indicated by the purple LED), suggesting the heater temporarily struggled to maintain temperature under aggressive airflow at maximum settings.

The airpath is not completely free-flow, which inherently limits how hard one can draw.

Temperature Stepping

Community opinion was divided on whether to use a single temperature or progressively increase temperature during a session:

Single-temperature approach: Some Pax 2 users preferred to find their personal "sweet spot" temperature and leave it there for the entire session. One member described leaving the Pax 2 on a single temperature as their standard approach, in contrast to their desktop vaporizer where they would step temperatures.
Temperature stepping: Other users followed the common practice of starting at the lowest setting for initial flavor hits and progressively increasing through the temperature settings to achieve more complete extraction.

Oven Lid Handling

One community reviewer noted that the oven lid could be handled immediately after turning the device off, though cautioned that this applied only under certain conditions — extended use at higher temperatures could make the lid too hot to touch comfortably.

Transitioning from Combustion

Users transitioning from combustion to the Pax 2 sometimes reported disappointment with visible vapor production. Community members offered practical advice:

Lighting conditions matter: Vapor is much more visible in certain lighting. Blue light, LED light (even from an LED TV), and early morning outdoor sunlight on cold days were all recommended for seeing vapor clouds more clearly.
Humidity plays a role: Cold, dry air makes exhaled vapor more visible.
Manage expectations: The Pax 2 is not designed as a cloud-chasing device. One member advised that visible clouds actually represent wasted vapor, suggesting that less visible exhales may indicate better absorption.

Temperature Guide

The Pax 2 offers four preset temperature levels:

Setting	Temperature	Community Notes
1 (Lowest)	360°F / 182°C	Best for flavor; lighter, more terpy vapor. Good for the first few draws of a fresh load.
2	380°F / 193°C	Often cited as a good "sweet spot" for balanced flavor and effect. Many users stayed here for most of their session.
3	400°F / 204°C	Increased vapor density; good for mid-to-late session use or when stepping up temperatures.
4 (Highest)	420°F / 216°C	Maximum extraction; thicker vapor but diminished flavor. Aggressive draws at this setting may temporarily overwhelm the heater, indicated by the LED dropping to purple (heating mode).

The community did not converge on a single "best" temperature for the Pax 2, as preferences varied based on desired effects:

Flavor-focused users tended to favor settings 1–2.
Effect-focused users or those seeking fuller extraction often used settings 3–4 or employed a stepping strategy starting low and ending high.
Users wishing to produce potent ABV (already been vaped) for later use in edibles sometimes deliberately vaped at lower temperatures to preserve some cannabinoids in the spent material.

Maintenance & Cleaning

Maintenance was one of the most frequently discussed aspects of Pax 2 ownership within the community. The device was widely acknowledged to require regular and thorough cleaning to maintain proper function, airflow, and vapor quality.

Cleaning Frequency

Community consensus suggested cleaning after every few sessions, or at minimum once per week for daily users.
Neglecting cleaning could lead to restricted airflow, degraded flavor, and potential mouthpiece detection issues.

Cleaning Procedure

Remove the mouthpiece and oven lid.

Clean the vapor path: Use a pipe cleaner dampened with isopropyl alcohol (90%+ recommended), inserted through the mouthpiece opening and pushed through to the oven.

Clean the oven: Use a cotton swab or pipe cleaner with isopropyl alcohol to scrub the interior walls of the oven.

Clean the mouthpiece: Soak in isopropyl alcohol and wipe clean.

Clean the oven screen: Remove any buildup with isopropyl alcohol and a small brush or swab.

Wipe down the exterior with a slightly damp cloth if needed (avoid getting liquid in the electronics).

Allow all components to dry completely before reassembling and using.

General Advice

Keeping the device clean was frequently cited as essential for maintaining acceptable flavor on the first few hits of a fresh load.
One community member emphasized that flavor quality was contingent on cleanliness, noting the Pax could produce "good taste for the first few hits (provided you keep it cleanish, but that goes for any vape)."

Common Issues & Fixes

Restricted Airflow

Cause: Resin buildup in the vapor path, particularly around the mouthpiece channel.
Fix: Regular cleaning with isopropyl alcohol and pipe cleaners. Maintaining a consistent cleaning schedule prevents this from becoming a significant problem.

Heater Dropping to Purple (Heating Mode) During Draws

Cause: Drawing too aggressively on the highest temperature setting can cool the oven faster than the heater can compensate.
Fix: Use a slightly slower, more moderate draw speed at the highest temperature setting. This is a design characteristic rather than a defect.

Odor / Smell During Use

Cause: Conduction heating and continuous oven operation produce more odor than many convection vaporizers.
Fix: No complete fix; this is inherent to the design. Users in discretion-sensitive situations were sometimes advised to consider alternative devices or switch to concentrates for maximum stealth.

Tolerance Buildup

One community member reported significant tolerance increases after three months of daily Pax 2 use (2–3 sessions per day), finding that half an oven no longer produced the same effects as initially experienced.
Community advice included: rotating strains to vary the cannabinoid profile, taking short breaks (even 1–2 days), trying different vaporizers to leverage different "vape signatures," and keeping session sizes to the minimum effective dose rather than over-medicating.

Accessories & Modifications

NewVape Accessories

The most frequently recommended aftermarket accessories came from NewVape:

Pax Pusher: An adjustable oven insert that allows users to load smaller amounts of herb while maintaining proper compression against the oven walls. This was one of the most commonly recommended accessories for improving the Pax 2 experience.
3D Screen: A replacement oven screen designed to improve airflow and evenness of extraction. One community member noted that "things improved with a bunch of NewVape accessories like the Pax-Pusher and 3D screen."

Grinders

Magic Flight Finishing Grinder (MFFG): Widely recommended as a second-stage grinder for achieving the fine consistency that the Pax 2 prefers. Typically used after an initial grind in a standard grinder. Available for approximately $20–22.
Santa Cruz Shredder (two-piece): Recommended as a quality primary grinder, often paired with the MFFG for the Pax 2.

Water Pipe Adapters (WPA)

The Pax 2 was occasionally used with glass bubblers through third-party adapters. While not as commonly discussed as WPAs for other devices (such as the Arizer Solo), community members did experiment with Pax-specific water pipe adapters to cool the vapor and improve the experience.

Degummed Hemp Fiber

Used as an oven filler to reduce load size. One community member noted that leftover hemp fiber accumulates vape resin over time and can eventually be reclaimed for its oil content.

Comparisons

The Pax 2 was frequently compared to other portable vaporizers in purchase-advice discussions within the community. Below are the most common comparisons:

Pax 2 vs. Arizer Solo / Air

This was one of the most frequently debated comparisons:

Flavor: The Solo and Air were generally considered superior in flavor due to their glass vapor paths and hybrid heating approaches. The Pax 2's all-metal airpath and continuous conduction heating produced less refined taste.
Portability/Stealth: The Pax 2 was clearly superior. The Solo was not pocketable, and even the Air, while more portable, still required glass stems that made it less discreet.
Maintenance: The Arizer products were considered significantly easier to maintain, with glass stems that could be quickly cleaned or swapped.
Efficiency: The Solo was generally considered more efficient per load.
Battery: The Air offered swappable 18650 batteries, a significant advantage for extended use away from a charger.
Value: The Solo was frequently available for ~$130–160, making it the common budget recommendation over the Pax 2. One member succinctly stated: "Best beginner portable vape = Solo."

Pax 2 vs. Original Pax

The Pax 2 was universally considered a meaningful upgrade. The simplified flat mouthpiece replaced the original's troublesome pop-up mechanism, the form factor was slimmer, and overall reliability improved.
Community members who had disliked the original Pax sometimes gave the Pax 2 (and later Pax 3) another chance with more positive results.

Pax 2 vs. Pax 3

The Pax 3 added Bluetooth app control, concentrate compatibility, a haptic feedback system, and faster heat-up times.
The Pax 2 and Pax 3 were considered similar enough that community discussions were eventually consolidated into a single thread covering all Pax models.

Pax 2 vs. Mighty / Crafty

The Storz & Bickel devices were considered superior in vapor quality, flavor, and extraction efficiency.
The Pax 2 held advantages in portability and form factor. The Mighty, in particular, was described as significantly bulkier.
One community member noted that the Mighty "blows [the Air] away" and became their most regularly used vaporizer despite owning a Volcano and Herbalizer — positioning it in a different performance class than the Pax 2.

Pax 2 vs. Firefly / Firefly 2

The Firefly devices were preferred by flavor-focused users due to their on-demand convection heating.
The Pax 2 was favored for its simpler operation and superior pocketability.
One community member who owned a Pax 2 and found it "fine" but "pretty smelly" and leaving them "wanting more" explored convection alternatives like the Firefly 2 for improved vapor quality.

Pax 2 vs. DynaVap VapCap

The VapCap was a frequent alternative recommendation, particularly for budget-conscious users or those prioritizing flavor and efficiency over electronic convenience.
One community member stated they had "not touched" their Pax 2 since getting a VapCap OmniVap, noting that the Pax 2 now served only as a backup.
The VapCap's requirement for a torch lighter was acknowledged as a significant limitation in certain situations (e.g., air travel, use in regions where quality lighters were hard to obtain).

Pax 2 vs. Boundless CF / Flowermate V5s

In budget-oriented comparisons, the Boundless CF was often recommended over the Pax 2 as offering better value for money.
The Flowermate was considered acceptable but unremarkable, with the Pax 2 offering a more refined user experience at a higher price point.
One community member recommended the Boundless over both the Pax 2 (which "needed additional accessories") and the Flowermate (which "didn't ring any bells").

Pax 2 vs. Grasshopper

The Grasshopper was considered the closer match to the Pax 2's stealth profile, with a pen-like form factor and on-demand heating.
However, the Grasshopper was noted for being "hot and harsh" and was plagued by reliability and company reputation issues. One member described the manufacturer as "an absolutely awful company to work with."

Summary of Community Positioning

The Pax 2 occupied a clear niche: it was the go-to recommendation for users who valued stealth, pocketability, and ease of use above all else. When users sought better flavor, the community pointed toward the Firefly or convection options; for better efficiency, toward the Solo or VapCap; for better overall vapor quality, toward the Mighty or Crafty. But for the specific use case of a discreet, attractive, pocketable session vaporizer, the Pax 2 remained a consistent recommendation throughout its active years in the community.
