In this guide
The short version
- All three are pocket-sized dry herb portables with replaceable screens; they differ in heating style, temperature control and battery.
- The Arizer Go SRT is the flavor and control pick: 75% convection, an all-glass vapor path, a degree-by-degree menu and a 5000mAh battery.
- The PAX Four is the simplest: four heat modes, a 0.3g oven, about 45 to 50 minutes of use per 90-minute USB-C charge.
- The Crafty+ gives you a 104°F to 410°F range, Super-Boost and the fullest box of spares, with 3 years of warranty once registered.
The PAX Four, the Storz & Bickel Crafty+ and the Arizer Go SRT are three portable dry herb vaporizers that land in the same part of our range, close enough that the spec sheet, not the sticker, usually decides it. One heats with a hybrid oven and four fixed modes, one is a button-and-boost Storz & Bickel in a pocket size, and one pushes hot air through an all-glass path and lets you set the exact degree. Here is what each of our product cards states, and who each one suits.
What the three share
All three are battery-powered portables built for dry herb, all three load into a chamber with replaceable screens, and all three ship with screens, a brush and a charging cable. None needs a torch or a wall base, and each fits a jacket pocket.
Past that the designs split. The PAX Four is operated by feel, with one button and a ring of LED petals. The Crafty+ is also one button, with a temperature range rather than fixed modes. The Go SRT has a display, a menu and three buttons, and it is the only one whose card states a heating split and a battery capacity. Control, heating and battery are the whole comparison.
Heating style and flavor
PAX calls the Four's heater a high-output hybrid and credits it with 50% more vapor, with an oven that holds approximately 0.3g lightly tamped. Our PAX card does not break the hybrid down into a conduction and convection share.
The Crafty+ card does not state a heating style at all, so we will not call it conduction or convection here. What it does state is the range, 104°F to 410°F, and a Super-Boost mode that takes the device to its maximum temperature when you triple-press the power button, meant for finishing a session with stronger vapor.
The Go SRT is the most explicit of the three: a 75% convection and 25% conduction hybrid, with an isolated borosilicate glass vapor path from the chamber to your lips. Arizer's point is that pre-heated air does most of the work, avoiding the over-cooking it says conduction-heavy pocket devices are prone to, and nothing in the path is metal. If flavor is what you rank first, this is the design built around it. Our conduction vs convection guide covers why that split changes the taste and the draw.
Temperature control: four modes, a range, or a menu
The PAX Four gives you four heat modes. With the device on, a quick press of the power button steps through them; wait three seconds or give it a quick shake and the setting locks. PAX says the higher modes make more vapor and use the battery faster, and suggests starting low and stepping up through the session. You never see a number, and for a lot of people that is the appeal.
The Crafty+ is a button device too, but it covers a stated 104°F to 410°F, and Super-Boost is the shortcut to the top of it. Our card does not describe how you pick a temperature inside that range; the Storz & Bickel instructions in the box do.
The Go SRT runs Arizer's SRT operating system: real-time temperature control across 122°F to 428°F, session timers you can set, and heating profiles you can save to suit how you draw. It heats in about 15 to 20 seconds and vibrates when ready. It is the only one that lets you set a precise degree, and the only one with a top end above 410°F.
On the PAX Four, swap to the flat mouthpiece if the vapor or the shell feels hot. PAX says it slows the airflow, which cools the draw and can increase vapor at the same time.
Battery, charging and heat-up
The PAX Four states about 45 to 50 minutes of use per charge, a full charge from empty in approximately 90 minutes over USB-C, and a battery read-out you get by shaking the device: each solid LED petal is 25%. PAX specifies a 5V to 9V charger at 2.5A minimum, and says a weak source is the usual reason a Four will not charge properly.
The Go SRT states a 5000mAh 21700 cell, USB-C charging and pass-through use while plugged in, with multiple sessions per charge rather than a minute figure.
The Crafty+ card states a USB cable in the box and a heat-up that is 30% faster than the original Crafty, and nothing about battery capacity, charge time or heat-up in seconds. That is a gap in the data we hold, not a mark against the device; the Mighty+ vs Venty comparison shows the brand's larger portables with fuller spec lines. If battery life decides it for you, the Go SRT is the only one you can judge on a number today.
Only the PAX Four and the Go SRT cards say USB-C. The Crafty+ card says "USB cable" without naming the connector, so do not assume you can share one lead across all three.

Loading, cleaning and the spares you will buy
The PAX Four ships with three oven screens, a multi-tool and a wire brush. PAX says to clean the screen and oven every few sessions, after ten minutes of cooling; the multi-tool pops the screen out, or the brush pushes it free from the mouthpiece side. The oven wants a medium-fine grind, packed full and lightly tamped.
The Crafty+ box is the most generous: three base seal rings, three normal screens, three coarse screens, two drip pads, a dosing capsule and a brush. Fill the capsule ahead of time and you drop it into the chamber instead of grinding over the device. The part that wears is the cooling unit, which is why Storz & Bickel sells a kit with a fresh one, mouthpieces, screens and pads for both the Crafty and the Crafty+.
The Go SRT's consumables are glass. The box holds a glass aroma tube with a mouthpiece tip, a Go Shell glass dosing capsule and a 14mm glass water pipe adapter; Arizer says to clean the glass with isopropyl alcohol. A retractable pop-up top covers the stem in a pocket. Arizer's loading advice is the opposite of PAX's: a coarse grind, seated flush in the tube or a capsule. Our cleaning guide walks through screens, chambers and glass in more detail.
The Go SRT is the only one of the three whose box includes a water pipe adapter. The PAX Four and Crafty+ cards list no adapter, so count that as an extra purchase if you want one.
Which one to buy
Buy the PAX Four if you want the smallest learning curve: four modes, one button, a shake to check the battery, and a 2-year warranty. Its 45 to 50 minutes per charge is the only run time stated in minutes here, so plan on a charger within reach for long sessions.
Buy the Crafty+ if you want a Storz & Bickel in a pocket size and you value a stated temperature range, Super-Boost for the end of a bowl, the fullest box of spares and the longest warranty of the three once you register it. Our card leaves the battery and heat-up figures out; the included instructions hold them.
Buy the Arizer Go SRT if flavor and control come first. It is the only one here with a stated convection-dominant heater, an all-glass path, a degree-by-degree menu, a 5000mAh battery and a water pipe adapter in the box. It asks a little more of you at the menu and at cleaning time.
If none of the three is quite it, the dry herb vaporizer collection holds the rest of our portables, and the Arizer collection has the Go SRT's glass and capsules.
Questions people ask
Which of the three heats up fastest?
The Arizer Go SRT states about 15 to 20 seconds. The Crafty+ card says 30% faster than the original Crafty without a figure, and the PAX Four card does not state a heat-up time.
Do the PAX Four, Crafty+ and Go SRT all charge over USB-C?
The PAX Four and the Go SRT do. The Crafty+ card lists a USB cable in the box without naming the connector, so check the included instructions before you count on sharing a lead.
Which one can I use with a water pipe out of the box?
Only the Arizer Go SRT, which includes a 14mm glass water pipe adapter. The PAX Four and Crafty+ cards do not list an adapter.
Which has the longest battery life?
The cards do not state it the same way. The Go SRT lists a 5000mAh 21700 cell and multiple sessions per charge; the PAX Four lists about 45 to 50 minutes of use; the Crafty+ card does not state a battery figure.
Which has the best warranty?
The Crafty+ carries 2 years plus 1 more when registered, the PAX Four 2 years, and our Go SRT card does not state a warranty term.
