PAX Plus: The Stealth Champion
The PAX Plus (9.8 x 3 x 2.1 cm, 93g) remains the gold standard for discreet portable vaping in 2025. Its sleek, minimalist design could easily be mistaken for a power bank or tech gadget, making it perfect for public use.
What sets the PAX Plus apart is its purpose-built "Stealth" mode, which minimizes visible vapor and odor, a feature particularly valued by urban users. After extensive testing in various public settings, I've found this mode genuinely delivers on its promise of discretion. The lip-sensing technology automatically cools the device when not in use, conserving battery and reducing odor.
The quick 20-25 second heat-up time and haptic feedback allow for discreet use without constantly checking the device. The magnetic oven lid makes for easy loading, while the flat mouthpiece design prevents pocket lint accumulation – a seemingly small detail that makes a significant difference during daily carry.
Battery life is solid at 8-10 sessions per charge, and the USB-C charging with magnetic connection adds convenience. The included carrying case provides excellent protection and odor containment, addressing a common concern for portable users.
Where the PAX Plus falls slightly short is vapor cooling – the mouthpiece can get quite warm during extended sessions at higher temperatures. However, for users prioritizing discretion and style in a pocket-friendly package, the PAX Plus is unmatched.

The standout feature is its exceptional vapor quality – smooth, flavorful, and consistent. The hybrid heating system (convection + conduction) delivers consistently excellent vapor quality that I've found rivals many desktop units. The cooling unit effectively conditions the vapor, allowing for comfortable use even at maximum temperature.
USB-C charging addresses a major weakness of the original Crafty, though battery life remains modest at 5-6 sessions. The super-boost mode (instantly raising temperature by 20°C) is perfect for finishing sessions quickly when on the move – a feature I've found particularly useful when needing to wrap up a session unexpectedly.
Dosing capsules are a game-changer for portable use, allowing pre-loaded sessions that keep the device cleaner and eliminate the need for carrying additional herbs. The medical-grade plastic construction has proven remarkably durable in testing, surviving multiple drops without issue during my outdoor adventures.
The Crafty+ companion app provides precise temperature control and customized settings, though basic functions are accessible without it. For users who value superior vapor quality and durability in a reasonably compact package, the Crafty+ represents an excellent, albeit premium-priced option at £195.00.

ArGo (Arizer Go): Glass Path Purity in a Pocket Size
The ArGo (9.3 x 5.2 x 2.4 cm, 126g) is Arizer's most portable offering, bringing their signature all-glass airpath into a genuinely pocket-friendly design.
The innovative pop-top design protects the glass stem when not in use, addressing the primary weakness of Arizer's other portable devices. This clever solution means you can confidently carry the ArGo in a pocket without worrying about breaking the stem – a feature I've come to deeply appreciate during my testing.
Vapor quality is exceptional thanks to the borosilicate glass pathway, delivering pure, flavorful clouds with no plastic aftertaste. The flavor preservation is among the best I've experienced in portable vaporizers, particularly at lower temperature settings. Temperature control offers precise 1°C adjustments from 50°C to 220°C (122°F to 428°F).
The removable 18650 battery system is ideal for travel, allowing easy swapping when power runs low. Battery life is solid at 6-8 sessions per charge. Pass-through charging is supported, though the micro-USB connection feels outdated in 2025.
Heat-up time is the ArGo's primary weakness at 60-90 seconds – significantly slower than most competitors. This makes it less suitable for quick, discreet hits on the go.
The ArGo is remarkably easy to clean and maintain compared to most portables, as the glass stems can be simply soaked in isopropyl alcohol. This convenience is particularly valuable during travel, where thorough cleaning options may be limited.
For users who prioritize vapor quality and are willing to sacrifice some heat-up speed, the ArGo offers exceptional performance in a genuinely portable package at £117.00. Its combination of flavor purity, replaceable battery, and protective design make it particularly well-suited for weekend trips and outdoor adventures.

Environmental impact: Arizer focuses on long-lasting borosilicate glass components that don't degrade over time. Their modular design allows for easy replacement of individual parts rather than disposing of the entire unit. Manufacturing takes place in facilities with environmental certifications.
"As a flavor enthusiast, nothing beats the ArGo's all-glass vapor path. The pop-top protection means I can confidently carry it in my pocket without worrying about breaking the glass stem. It's become my go-to weekend companion." - Tina R., Wine Sommelier
PAX Mini: Ultra-Portable Simplicity
The PAX Mini (7 x 2.2 x 2 cm, 54g) is the most compact option in our lineup, focusing on extreme portability and simplicity. At just 54 grams and 7cm tall, it disappears into even the smallest pockets – making it the true champion of ultra-portable devices.
This tiny device delivers surprisingly good performance for its size, with a respectable 22-second heat-up time. The magnetic oven lid makes loading quick and easy, while the flat mouthpiece design contributes to its ultra-discreet profile.
Battery life is limited at 4-5 sessions per charge – the inevitable trade-off for such a compact device. The proprietary charger is less convenient than USB-C options, but the charging time is reasonable at about 90 minutes from empty.
The PAX Mini offers four temperature settings rather than precise degree-by-degree control. While this simplifies operation, it may frustrate users who prefer exact temperature customization. In my testing, I found the preset temperatures to be well-chosen for most users' needs.
The lip-sensing technology, which automatically heats when drawn from and cools when set down, is particularly valuable in such a small device, maximizing both battery efficiency and discretion.
Vapor quality, while good for the size, doesn't match larger premium devices. The vapor can be on the warmer side, and the flavor, while decent, isn't as pure as glass-pathway alternatives.
For users who prioritize ultimate portability and discretion above all else, the PAX Mini excels at £105.00. It's ideal as a secondary device for situations where size matters most, or as a primary device for light, occasional users who value minimum pocket bulk.
What's in the box: PAX Mini device, flat mouthpiece, multi-tool, maintenance kit, charging cable, quick start guide
Environmental impact: Similar to the PAX Plus, the Mini benefits from PAX's device recycling program and minimal packaging approach. The simplified design uses fewer materials overall.
"I bought the PAX Mini specifically for music festivals where security can be strict. Its tiny size means it's virtually undetectable in a pocket, and the quick heat-up time is perfect for grabbing a hit between sets without missing anything." - Alex P., Concert Photographer
Firefly 2: On-Demand Specialist
The Firefly 2 (13 x 3.6 x 2.4 cm, 140g) offers a unique proposition in the portable market with its on-demand convection heating system. Unlike session vaporizers that maintain temperature throughout a session, the Firefly 2 heats only when you draw, reaching temperature in an astonishing 3-5 seconds.
This on-demand approach makes it perfect for microdosing and quick, discreet hits throughout the day. There's no need to commit to a full session – take a quick draw and pocket the device immediately. In my testing, this feature proved invaluable for situations where I wanted a quick hit without committing to a full session.
The borosilicate glass bowl and vapor path deliver exceptional flavor purity, revealing subtle terpene notes often lost in other devices. Dynamic heating technology gradually increases temperature during inhalation, producing a full spectrum of flavors.
Battery life is modest at 4-5 bowls per charge, but the removable battery system allows for spares. The device does require a proprietary charger, which is less convenient for travel than USB options.
The Firefly 2 has a steeper learning curve than most portables – drawing technique significantly impacts vapor production. This makes it less immediately satisfying for beginners but rewards those who master its use. I found it took me several sessions to really dial in the perfect technique.
The magnetic lid allows for easy loading, though the smooth exterior can be somewhat slippery. At £329.95, it represents a premium investment, but its efficiency in material consumption can offset this cost over time.
For users who prefer multiple quick sessions throughout the day rather than longer continuous sessions, the Firefly 2's instant-on capability and superior flavor make it a compelling choice despite its larger size and higher price point.
What's in the box: Firefly 2 device, removable battery, charging dock, cleaning kit, concentrate pads, USB cable
Environmental impact: The glass and metal construction is highly recyclable. The company offers a battery recycling program and emphasizes the device's material efficiency as an environmental benefit (uses less material per session).
