Arizer Solo 2

Replaceable 18650 battery (3,400 mAh). Runtime is 90-120 minutes depending on temperature — roughly 15-20 sessions at 5 minutes each.

Spare cells cost under €10 and swap easily: unscrew the bottom cap, pull out the battery. Pass-through charging via Micro-USB works.

The Solo 2 MAX offers the same core performance with USB-C and longer runtime (~3 hours). If you already own a Solo 2 and are happy, no need to upgrade.

Battery Tips for Maximum Lifespan

• Don't store at 100% constantly: 18650 cells last longer when stored between 20% and 80%.
• Rotate spare batteries: Using two batteries in rotation extends the overall lifespan of both.
• Use passthrough sparingly: Charging during use stresses the battery more than normal charging.
• Original battery: Arizer recommends the included 18650 — cheap no-name cells may reduce performance.

Charging Times Overview

Method	Duration (0→100%)	Note
Micro-USB (included)	~3–4 hours	Standard method
External 18650 charger	~2 hours	Faster, gentler on battery
Passthrough	Longer (simultaneous use)	Works but not ideal

Two aroma tubes included: standard (straight) and frosted (cools slightly more, fits more snugly). Both borosilicate glass, both compatible with water pipe adapters (14 mm / 18 mm sold separately).

Stainless steel dosing capsules are available and keep the chamber clean. Without capsules: 0.15-0.2 g. With capsule: about 0.1 g.

The stems protrude from the top — making the Solo 2 less pocket-friendly than the ArGo, but the longer vapor path delivers cooler draws.

Stem Types Compared

Stem	Feature	Recommended for
Standard (clear)	Smooth surface, easy to clean	Daily use
Frosted	Matte surface, tighter fit, slightly better cooling	On the go (less wobble)
Short stem (110 mm)	More compact, less cooling	Discreet transport
WPA 14/18 mm	Water pipe connection, maximum cooling	At home with bubbler

Cleaning the Glass Stems

Isopropyl alcohol (90%+) and a zip bag are all you need: place the stem inside, wait 30 minutes, rinse with hot water. Stubborn residue also dissolves when simmered in milk (the fats bind the resin). Clean the chamber in the device itself with the included brush — never put alcohol into the device.

LED display with current and target temperature. Two-button controls: up and down. Up to 10 programmable session presets for different temperatures.

Auto shut-off after adjustable time (default: 15 minutes). No Bluetooth, no app — Arizer keeps it deliberately simple. For more control, look at the Solo 3 V2 with color display and on-demand mode.

Session Workflow in Practice

1. Fill the stem: 0.15–0.2 g medium grind, loosely packed. Don't tamp down.
2. Power on: Press button 5×. Display shows heat-up phase (~30 s).
3. Inhale: Slow, steady draws over 5–10 seconds.
4. Increase temperature: After 3–5 draws, raise by 5–10 °C for more extraction.
5. End session: Device auto-shuts off after 15 min, or press 5× manually.

Setting Up Presets Effectively

The Solo 2 stores up to 10 temperature presets. In practice, 3–4 are enough:

• Preset 1 (Flavor): 180 °C — first draws of a fresh fill
• Preset 2 (Standard): 195 °C — everyday setting for most users
• Preset 3 (Intense): 210 °C — last draws or denser clouds

On-demand mode is the big innovation in the Solo 3 and distinguishes it from the Solo 2. Here you start each inhalation separately – like a mini session. The display shows a progress bar and beeps when the temperature is reached. Then you have a 10-second draw window (adjustable between 5-25 seconds). After the draw, the device immediately cools down and preserves your material. The genius part: You can take one draw, put the device away, and come back an hour later – the herb is preserved, not overcooked like in session mode. There are five heat levels that are not customizable but fixed at 180°C, 185°C, 193°C, 205°C, and 220°C. Per XL stem, you get 2-5 powerful draws, depending on the heat level. On-demand mode also allows intense single-hit extractions: Set it to maximum temperature and 25-second draw duration, then you can extract a complete load in a single, long draw. This is especially interesting for water pipe use. The control is precise – no accidental overheating like with butane vaporizers. On-demand mode makes the Solo 3 a versatile device that adapts to your consumption rhythm.

The Solo 3 package includes four glass stems: two straight (90mm regular + XL) and two water pipe adapters (regular + XL, with frosted tips). The XL stems are the highlight because they hold double the amount of herb – about 0.2g instead of 0.1g. That means more flavor, thicker draws, and stronger effects per session. The XL stems make particular sense on the Solo 3 because the heating chamber is deeper than on the Solo 2 or Air MAX. On the Solo 2, the herb in XL stems sat too close to the seal where there's no heat – on the Solo 3, it sits optimally in the heating zone. Loading works best directly from the grinder: Turn the stem in the herb to fill it. From a jar: Dip the stem in and turn. Then lightly tamp with your finger, make a half turn, and the herb should stay just below the lip – not too tight, or airflow suffers. The glass stems cool the vapor considerably. Heat is generated at the bottom of the stem (which is why the herb browns there first), and by the time the vapor reaches the top, it's pleasantly cool. The WPA stems have a frosted tip for better grip on the water pipe glass. Important: Empty the stems immediately after the session, or the AVB sticks to the glass. A brush for the glass holes keeps everything clean.

The color display is an upgrade over the Solo 2. It's brighter, sharper, and has more color levels. The brightness setting ranges from 1 to 5, and even at full brightness, battery consumption is minimal. Operation is via three buttons: Power, left, right. To unlock the device, hold Power for three seconds, then press left-up-right in that sequence. On the mode selection screen, you choose Session or On-Demand. Double-clicking a button recalls the three customizable presets. Holding the right button takes you to the settings menu: draw duration (5-25s), Celsius/Fahrenheit, notifications, brightness, display inversion, and auto-shutoff (5-20 minutes). Display inversion is a clever feature: When you flip the Solo 3 upside down for water pipe use (stem facing down), the device detects the orientation and automatically rotates the display. Button functions also rotate – what was previously "left" is now "right". This makes operation intuitive regardless of position. The UI is overall well thought out and after a few sessions, you know where everything is.

The Solo 3 uses an 80% convection / 20% conduction hybrid heating system. Conduction keeps the glass warm, but actual extraction happens through convective heat when drawing. This balance is ideal: The glass is preheated, but the herb doesn't char between draws like with pure conduction. Real-time temperature regulation is based on airflow: If you pull hard, the device heats more to maintain temperature. If you pull gently, it holds naturally. The AVB comes out brown and crispy – a sign of complete extraction. No green spots, no wasted cannabinoids. Heat comes from the bottom of the stem, which is why the bottom of the herb browns first. The sweet spot is at 193°C (380°F). Below that, the AVB stays only brown; above that, the bottom turns blackish. At 193°C, you get maximum flavor, thick clouds, and clean AVB. The glass stems cool the vapor considerably – by the time it reaches your lips, it's pleasant. The first 4-6 draws in session mode are outstanding in flavor, after which intensity decreases even though vapor still comes. Slow draws ("sip don't rip") is the best technique.

The Solo 3 comes with two water pipe adapters (WPA): regular and XL, both with frosted glass tips for better grip. The WPAs fit any 14mm bubbler. When you flip the Solo 3 upside down (stem facing down into the water pipe), the device detects the inversion and automatically rotates the display. Button functions also rotate, so "left" becomes "right" and vice versa – very well thought out. For water pipe use, on-demand mode is recommended. Set it to high temperature (205-220°C) and long draw duration (20-25s), then you can take intense, thick draws. The water additionally filters the vapor, so even high temperatures remain pleasant. You can even extract a complete load in a single draw if you pull for 25 seconds at maximum level. The XL WPA stems are particularly powerful here because they hold double the amount of herb. That means more material for your bubbler session. A tip: After reaching temperature, let the device sit for 10-20 seconds before drawing – this ensures a thicker first hit. The combination of Solo 3 and water pipe is a match made in heaven: precise temperature control, strong extraction, smooth vapor.

The Solo 3 V2 has a 5,000 mAh replaceable battery – one of the largest on the market. Per charge, you'll get about 10 sessions, which is top-tier and comparable to the Venty. The battery is replaceable, so you can double runtime with a spare battery. This is ideal for festivals, hikes, or long days on the go. Charging is via USB-C Power Delivery, which is faster than regular USB. Passthrough charging is supported, meaning you can vape while the device is plugged in. A full charge takes about 2-3 hours. The display shows battery status in percentage, so you always know where you stand. Compared to other portables, the runtime is excellent. Devices like the Pax Plus only manage 6-7 sessions; the Solo 3 significantly exceeds that. The combination of large battery, efficient heating, and replaceable battery makes the Solo 3 one of the most reliable portable vaporizers. A spare battery costs about 30-40€ and is a worthwhile investment if you're often on the go.

1. Draw slowly: "Sip don't rip" is the motto. Slow, steady draws give the convection time to extract the herb. Fast, hard pulls can't maintain temperature. 2. Inhale during heatup: As soon as you start "Heat", you can already pull lightly. Terpenes vaporize at low temperatures first – you'll get an intense flavor draw before the target temperature is reached. 3. Wait 10-20 seconds: When the target temperature is reached, wait briefly before taking the first draw. The herb and glass need a moment to absorb the heat evenly. The first draw will be thicker. 4. Empty stems immediately: After the session, tap out the AVB from the stem while it's still warm. When it cools, it sticks to the glass and is harder to remove. 5. Brush the glass holes: A small brush (often included) cleans the screen holes in the stem. This keeps airflow optimal. 6. Don't overload: The herb should stay just below the lip of the stem. If it touches the heating element, it will stick and airflow suffers. 7. Temperature stepping: Start at 185°C, bump to 193°C after a few draws, and finish at 205°C. This way you get everything from your material. 8. XL stems for intensity: If you want thick draws and strong effects, use the XL stems. They hold double the amount and deliver correspondingly more vapor.

Regular cleaning keeps the Solo 3 V2 performing at its best and ensures pure flavor. Brush out the chamber after every session to remove loose residue. Clean the mouthpiece and vapor path weekly with isopropyl alcohol (90% or higher).

Cleaning Schedule

Component	Frequency	Method
Chamber	After each session	Brush, tap out
Mouthpiece	Weekly	ISO soak (15 min)
Vapor path/screen	Every 2 weeks	ISO soak, rinse
Exterior	As needed	Damp cloth

Common Mistakes to Avoid

• Never use water inside the chamber — only isopropyl or dry cleaning
• Do not use sharp metal tools in the vapor path
• Replace screens when draw resistance increases

Choosing the right temperature on the Solo 3 V2 determines flavor, vapor density, and active compound profile. Lower temperatures (170–185 °C) emphasize terpenes and deliver mild, aromatic vapor. Higher temperatures (195–210 °C) produce thicker clouds and stronger effects.

Temperature Zones

Zone	Range	Result
Flavor	170–185 °C	Mild, aromatic, light vapor
Balanced	185–195 °C	Good flavor with visible vapor
Dense clouds	195–210 °C	Thick vapor, stronger effects

Practical Tips

• Start at 180 °C and increase in 5-degree steps
• Finer grind often needs 5–10 °C lower temperature
• In cold environments, raise starting temp by 5 °C

The Solo 3 V2 battery lasts several sessions with typical use. For maximum lifespan, keep the battery between 20% and 80% and avoid deep discharge. USB-C charging with a quality power adapter speeds up charging.

Battery Tips

• Do not leave on the charger permanently — unplug after 100%
• For replaceable batteries: use original or recommended cells
• Battery performance drops in cold — let it warm up before sessions
• Pass-through charging (if supported) allows use while charging
