The Arizer Solo 3 delivers convection-dominant hybrid vapor through an all-glass path, producing some of the cleanest flavor we've tasted from a portable vaporizer. With 13 sessions per charge in our testing and dual session/on-demand modes, it's built for cannabis users who want both taste and endurance.
The Solo 3 undercuts the Mighty+ 8.7 on price while betting on convection-dominant hybrid heating and borosilicate glass. The 80/20 convection-to-conduction ratio produces terpene-forward flavor, and the battery earns it the endurance pick in our portable rankings.
Glass stems add bulk and fragility. The controls have a learning curve, and there's no companion app. For users who prioritize flavor and marathon battery life, the Solo 3 makes a case that's hard to ignore.
What changed in the Solo 3 V2.0
V2.0 is the Solo 3 Arizer sells now, and it's the one we tested. It charges over USB-C PD, so any USB-C PD charger works. The screen flips automatically when you run it upside down on a water piece. It also comes in a Sea of Green color. The heater, the glass stems and the two heating modes carry over from the first Solo 3.
What's in the Box
Arizer packs four borosilicate glass aroma tubes with the Solo 3. You get a standard stem, an XL stem with five airflow holes and a bigger bowl, and two water pipe adapter stems for bong use. A USB-C charging cable, stainless steel stirring tool, and silicone stem caps complete the kit. It is a generous box.

Aluminum body weighs 280 g and favors home use
The Solo 3's body is machined from anodized aluminum, with a ceramic heater and borosilicate glass aroma tubes. At 280 g before you add a stem, it has real heft for a portable.
The cylindrical body (130 × 49 × 32 mm) sits stable on flat surfaces and rests naturally in your hand. The brushed aluminum fills a palm without crowding it, and the color display stays readable even in low-angle sun. Attach a glass stem and the total height rules out pocket carry entirely. Arizer backs it with a lifetime warranty on the heater, 2 years on the vape and 1 year on the battery. The glass isn't covered.

The glass stems are the vulnerability. One drop on a hard floor and they shatter. Budget for a spare set, especially if the vape travels in a bag.
Convection-dominant hybrid through glass produces flagship-tier flavor
The Arizer Solo 3 is one of the best-tasting portables we've tested. Its convection-dominant hybrid heater (roughly 80% convection, 20% conduction) heats the cannabis sitting in the bowl of the glass aroma tube. That same glass tube carries the vapor to your mouth, which is where the clean taste comes from.
Temperature control spans 50-220°C in 1°C steps, with the heater reaching your target in 15 seconds. The XL stem holds up to 0.5 g, and the standard stem takes a smaller load. Because convection drives extraction, airflow matters more than how tightly you pack the chamber.

Draw resistance leans toward the restricted side. The Solo 3 rewards slow, patient sips rather than deep lung pulls. If you're used to open-draw vapes, you'll need to adjust your technique, and our draw technique guide covers how to dial in a restricted draw. The color display stays legible at arm's length, which matters when you're chasing the top of the temperature range.

Session and on-demand modes in one vape
Dual-mode operation is one of the Solo 3's defining features. In session mode, the heater holds your set temperature for up to 20 minutes, ideal for slow sipping through a full oven. Switch to on-demand mode and a press of Up fires a short timed heat cycle (Down cancels it), so the heater cools down between hits.
On-demand mode is where the Solo 3 impresses most. The heater reaches temperature in seconds, and you can adjust the heat timer to match your inhale.

Smoother, cooler draws through a water piece
The included WPA stems turn the Solo 3 into a strong water piece companion. Load a WPA stem in place of the standard glass stem, seat it in a water piece, and the draws come through smoother and noticeably cooler than in direct-draw mode. For a step-by-step setup, see our water pipe connection guide.
Running the vape upside down on a bong also cuts way down on loose cannabis falling into the oven, a common frustration with upright use. We start most sessions through glass at 190°C.

XL stem can produce uneven extraction
The XL stem's larger chamber sometimes roasts the bottom layer darker than the top, especially at higher temperatures. The standard stem delivers more consistent results across the full oven. A coarser grind and gentle tamping improve evenness in both stems, and keeping session mode below 200°C helps the XL perform more evenly. How evenly your cannabis packs against the mesh screen at the oven end of the stem decides how evenly the load extracts.

Best Arizer Solo 3 temperature settings
Session mode holds your set temperature for up to 20 minutes, so these are the numbers we dial in for a full load.
| Setting | When to use it |
|---|---|
| 190°C | Our starting point for most sessions, direct draw or through a water piece |
| Below 200°C | Session mode with the XL stem, for more even extraction |
| 220°C | The top of the range, and the empty burn-off Arizer specifies before first use |
In on-demand mode, a press of Up runs a timed heat cycle. Adjust the heat timer to match your inhale, so the cycle ends when your draw does.
Battery powers 13 sessions on a single charge
From a full charge to empty, the Solo 3 gave us 13 sessions. Each one was a full load in session mode at the temperatures we recommend in this review, starting around 190°C. Our How We Test page covers the method. On-demand mode can stretch that further, depending on your temperature and heat time. That outlasts the majority of portables we've tested and makes the Solo 3 a genuine all-day vape.
Pass-through charging over USB-C lets you vape while plugged in, turning the Solo 3 into a tethered desktop. If the battery is fully drained, give it 5 to 10 minutes on the charger before your first hit. A full charge takes about 180 minutes from empty, a little longer if you vape while it charges. On units that show ECO CHARGE, charging stops at 80% by default, and holding Up while it's connected charges it to full. The USB-C port sits cleanly in the anodized aluminum base, with no flap or cover to fumble with.

The battery is not user-replaceable. Arizer runs a battery replacement service, and the battery carries its own 1-year warranty. Factor that in if long-term serviceability matters more to you than built-in capacity.
How to use the Solo 3: loading, controls and cleaning
Packing the glass aroma tube is straightforward: grind your cannabis, press the tube into the ground material (straw-packing works well), and insert it into the heated oven. The details matter more than they first appear.
Grind too fine and particles pull through the stem's screen holes into your mouth. Too coarse and extraction drops off. A medium-coarse grind with gentle tamping hits the sweet spot.
Flipping the grinder upside-down for a few turns gets the right consistency. Then load the glass aroma tube straight from the open grinder, no scooping or funneling required.

Controls and the unlock sequence
The unlock sequence (left, up, right on the buttons) feels clunky the first few days but becomes muscle memory within a week. On the V2.0, the screen flips automatically when you run it upside down on a water piece. There's no companion app, no Bluetooth, and no firmware update path, so all controls run through the buttons and color display on the vape itself. For a vape Arizer clearly intends to last years, the lack of an update mechanism is a missed opportunity.
Glass stems make cleaning almost effortless
Drop the cooled stems in isopropyl alcohol for a couple of hours, then rinse them well and let them dry completely. A spare stem keeps you vaping while one soaks. Keep liquids out of the heater itself. Using the vape with a water piece (stem pointing up) keeps the oven noticeably cleaner.

Third-party dosing capsules inside the stems keep loose material contained. Pick a capsule that fits your stem without choking the airflow, and give the glass a soak now and then.

Arizer Solo 3 vs Mighty+
The Mighty+ uses hybrid heating (conduction plus convection) through a ceramic-coated filling chamber. The Solo 3 runs convection-dominant hybrid heating through an all-glass path. In practice, the Solo 3 produces cleaner terpene separation while the Mighty+ delivers denser, thicker clouds with less technique required.
Battery life favors the Solo 3: 13 sessions versus 11. Heat-up is 4x faster at 15 seconds versus 60. The Mighty+ supports official dosing capsules and offers a more intuitive button interface.
The Solo 3 costs $100 less at US list price, making it a compelling value pick if flavor and battery life are your priorities. The two footprints are close, though the Solo 3's stem adds height. For a full breakdown, see our Solo 3 vs Mighty+ comparison.

Arizer Solo 3 vs Crafty+
Storz & Bickel's Crafty+ 8.2 Being phased out is the pocketable alternative: 135 g against 280 g, plus app control and official dosing capsules the Solo 3 can't match. Battery is the split, 5 sessions per charge against the Solo 3's 13, and the all-glass path still wins on vapor quality for us. Our Solo 3 vs Crafty+ comparison works through both sides.
Arizer Solo 3 vs Venty
The Venty 9.2 opens up the draw with adjustable airflow and heats in 20 seconds, for denser vapor with less effort. The Solo 3 counters with a purer glass vapor path, 2 extra sessions per charge (13 vs 11) and a $150 lower US list price ($299 vs $449).

Arizer Solo 3 vs Arizer Solo 2 Max
The Arizer Solo 2 Max 8.2 shares the all-glass vapor path, runs session mode only and costs $80 less at US list price. It edges ahead on battery at 15 sessions per charge. The Solo 3 earns the upgrade with dual session/on-demand modes, faster 15-second heat-up, and the terpene clarity that convection-dominant heating delivers. The Solo 3 is the bigger vape: 130 mm and 280 g against 113 mm and 210 g. That extra bulk buys you the second heating mode and the faster heat-up. Our Solo 3 vs Solo 2 Max comparison sets the specs side by side.

The third Arizer worth weighing is the Air Max 8.0 , which matches the Solo 3's 13 sessions per charge. It runs on a user-swappable 26650 cell in a 160 g body. The catch: it heats in 60 seconds, runs session mode only, and lists a smaller 0.15 g bowl. Our Solo 3 vs Air Max comparison shows what the Solo 3's extra bulk and cost buy you.
Who Should Buy the Arizer Solo 3
Flavor-first users will find the all-glass convection vapor path delivers terpene clarity that few portables can match.
All-day home vapers who run multiple sessions daily get 13 sessions per charge plus pass-through charging, so you can keep vaping while it's plugged in.
Water piece enthusiasts receive two dedicated WPA stems in the box, and the Solo 3 performs noticeably better through glass than in direct-draw mode.

Skip it if:
- You want a pocket vape. With a stem fitted it's too tall, and the Crafty+ at 135 g is the better carry.
- You want an open, airy draw. The Solo 3 rewards slow sips, and the Venty pulls far looser.
- You want app control or official dosing capsules. The Venty has both, and the Mighty+ takes official capsules too.
- You're hard on gear. The glass stems break on a hard floor, and the warranty doesn't cover glass.
Final Verdict: Is the Arizer Solo 3 Worth It?
Yes, if you vape mostly at home and want some of the cleanest flavor we've tasted plus 13 sessions per charge, at a $299 US list price. Convection-dominant hybrid heating through an all-glass path produces terpene clarity that few competitors can match, and the battery makes charging anxiety a non-issue.
Accept the glass stem trade-offs, and this vape rewards you session after session. It's the endurance pick in our portable ranking, and the portable we recommend for anyone who wants clean flavor and all-day battery in one.
