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

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

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

The MAX is an upgrade, not a redesign:

If you do not own a Solo yet and budget allows, get the MAX. If the Solo 2 is within your budget: go for it — vapor quality is identical.

A special feature of the VENTY is its continuously adjustable airflow via the dial on the bottom of the device. This allows each user to customize draw resistance to their preference:

The innovative flowmeter in the VENTY measures the negative pressure during inhalation and dynamically adjusts heating power – ensuring optimal vapor production with every draw.

How to Set the Airflow: Practice Over Theory

In practice, the VENTY's vapor output depends not just on temperature, but on the combination of airflow, draw duration, and chamber condition. For consistent sessions, start with a fixed setup and change only one variable at a time. This helps you find your personal sweet spot faster.

Common Airflow Mistakes with the VENTY

• Too low temperature at maximum airflow: often produces thin vapor and unnecessarily long sessions.
• Overpacked chamber: artificially increases draw resistance and reduces convection efficiency.
• Quick, short draws: better to inhale steadily for 4–8 seconds rather than short, hard puffs.
• Neglected cleaning: residue in the cooling unit changes airflow behavior and degrades flavor.

Users switching from the Mighty+ to the VENTY benefit most from the more versatile draw character. This makes the VENTY the better choice for many in varying situations: relaxed at home with medium airflow or on the go with open airflow for quick, strong draws.

The VENTY is equipped with two powerful lithium-ion batteries and supports USB-C Power Delivery for fast charging.

Charging Options:

• Fast charging (recommended): 80% in just 40 minutes with the official STORZ & BICKEL USB-C Supercharger (15V @ 3A). The display shows fast blinking during fast charging.
• Standard charging: Possible with other USB-C chargers, but takes significantly longer. The display shows slow blinking.
• ECO charging mode: Activatable via the Web App – optimizes charging speed and extends battery life through moderated power delivery.

Important note: The VENTY does not support pass-through charging (charging while in use). Since the device requires over 100 watts during operation, this exceeds the maximum power output of USB-C chargers.

When all six status fields on the display are constantly lit, the battery is fully charged. The charger should always be disconnected after charging.

Real-World Battery Life

Storz & Bickel advertises about 20 sessions per charge – in daily use, expect 10 to 14 sessions realistically. Heavy use of Booster or Superbooster mode drains the battery noticeably faster. The battery consists of two 18650 lithium-ion cells with a combined capacity of 5,940 mAh and is not user-replaceable.

From a user perspective, multiple reviews rate the battery as mid-range — particularly at higher temperatures and heavy use. At the same time, the fast USB-C charging is highlighted as a clear advantage.

According to Friendly Aussie Buds (24 June 2025), VENTY availability can vary considerably depending on the country and regulatory framework (in the video specifically referencing Australia).

Real-World Battery Life: Realistic Expectations

Actual battery life depends heavily on temperature, airflow setting, and draw behavior. At moderate settings, more sessions are possible than at constantly high temperatures with open airways and Booster use. The following table provides orientation:

Tips for Better Battery Efficiency

• Don't start at 210 °C unnecessarily: better to increase gradually when needed.
• End sessions deliberately: turn off after target extraction instead of letting it run idle.
• Use ECO charging mode wisely: useful for users who prioritize long-term battery health.
• Use suitable chargers: stable USB-C PD chargers reduce charging times significantly.

Pass-Through and Charging in Practice

The VENTY does not support pass-through charging. This is not a defect but a deliberate design decision due to the high power requirements during operation. For many users, a second charging setup makes sense (e.g. one charger at home and one for travel), so spontaneous sessions don't fail due to a dead battery.

For buyers focused on daily usability, the combination of fast charging, clear remaining capacity display, and stable session performance matters most. These points are highlighted positively in multiple reviews, even though absolute battery life is perceived differently depending on usage style.

Safety Instructions Before First Use:

• Fully charge VENTY with the included USB-C cable
• Check device and power supply for visible damage – do not use damaged devices
• Check airflow: mouthpiece and cooling unit must be free of foreign objects
• Do not block air vents during operation or cooling

Filling the Chamber:

1. Turn cooling unit 90° counter-clockwise and remove
2. Fill ground herbs up to the plastic rim – do not overfill or pack tightly!
3. Replace cooling unit and turn 90° clockwise to secure

Tip: When using dosing capsules, airflow may be slightly restricted.

Using Concentrates

The VENTY does not come with a dedicated concentrate adapter. For waxes or oils, use the Storz & Bickel Liquid Pads (15 mm). Place the pad in the filling chamber to prevent concentrate from seeping into the device. A set costs around €10 and is sold separately. For concentrates, a lower temperature around 180°C works best.

Vaporizing – Step by Step:

1. Turn on device with long button press and wait for green light (~20 seconds)
2. Fold out mouthpiece
3. Inhale steadily for a few seconds – only about half as deep as possible
4. Hold breath for a few seconds
5. Exhale slowly

Important: Never blow into the device! Pay attention to body reactions (coughing, chest discomfort) – consult a doctor if in doubt. Automatic shut-off occurs after 2 minutes of inactivity.

Regular cleaning is essential for optimal vapor quality and longevity of the VENTY. Storz & Bickel recommends cleaning the screens with the included brush after each use.

Before Cleaning:

• Turn off vaporizer and let it cool down
• Disconnect USB-C cable
• Remove filling chamber screen
• Wipe housing only with a dry or slightly damp cloth – never wet!

Method 1: Warm Soapy Water (gentle)

1. Soak cooling unit and all screens in warm soapy water for at least 5 minutes
2. Rinse thoroughly under running water for at least 1 minute
3. Let dry completely before reinserting

Method 2: Isopropyl Alcohol (for stubborn residue)

1. Soak parts in isopropyl alcohol for maximum 30 minutes
2. Rinse thoroughly under running water (at least 1 minute)
3. Let dry completely – no alcohol residue!

Check regularly: Inspect all parts for cracks, discoloration, brittleness, or damage. Replace damaged parts immediately – replacement parts are available from Storz & Bickel.

Wear Parts & Replacement Costs

Screens and sealing rings are the typical wear parts on the VENTY. Depending on usage, they should be replaced every 3 to 6 months. Storz & Bickel offers Wear & Tear Sets for around €30–50 that include all common replacement parts. Original spare parts are available directly from the Storz & Bickel online shop.

The VENTY can optionally be controlled via the STORZ & BICKEL Web App. The app is not required for operation but offers extended features:

• Precise temperature calibration – set custom values for Base, Booster, and Superbooster
• Adjust display brightness (levels 0-9)
• Activate ECO charging mode for longer battery life
• Firmware updates – always the latest software for optimal performance
• Device diagnostics and error analysis
• Device reset to factory settings

Connecting:

1. Enable Bluetooth on your smartphone/tablet
2. Open browser (recommended: Bluefy on iOS, Chrome on Android)
3. Visit app.storz-bickel.com
4. Turn on VENTY
5. Follow the Bluetooth pairing instructions on screen

Tip: Firmware should be updated regularly to ensure best performance and future compatibility.

Firmware Issues & Error Codes

Earlier firmware versions occasionally triggered error codes E04 and E05 – usually related to temperature sensor faults or communication issues. The firmware update to version 1.07 has largely resolved these problems. If you have trouble connecting to the Web App: it relies on the Web Bluetooth API, which is not supported by all browsers. Chrome works most reliably – Safari and Firefox may cause connection drops.

For thorough cleaning or replacement of wear parts, the VENTY can be disassembled. Follow these steps to remove the cooling unit and all screens.

Disassembly:

1. Open mouthpiece: Place the edge of the mouthpiece into the notch on the rotating cap and turn counter-clockwise to open and remove.
2. Remove sealing ring: Pull the sealing ring off the rotating cap at the recess.
3. Remove cooling unit cap: Carefully pull the cooling unit cap off the vaporizer.
4. Remove cooling unit screen: Pull out the screen in the cooling unit.
5. Release adjustment wheel: Use the filling chamber tool to push the adjustment wheel out of the cooling unit. The sealing ring will fall out.
6. Unscrew cooling unit base: Turn the cooling unit base 90° counter-clockwise off the vaporizer.
7. Remove filling chamber screen: Gently push the screen out from above with a cotton swab.
8. Release base sealing ring: Pry out the large base sealing ring with the filling chamber tool at the recess in the slot.

Assembly:

Follow the instructions in reverse order. Note:

• Place the sealing ring directly on the airflow adjustment wheel – the "TOP" label must face up
• Ensure all sealing rings are properly seated and not kinked
• Insert screens into their designated grooves
• Turn cooling unit 90° clockwise to secure

Important: Damaged or deformed sealing rings should be replaced immediately to ensure optimal air-tightness and vapor quality. Replacement parts are available directly from Storz & Bickel.

Choosing the right temperature on the Venty 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

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
