Firefly 2+

Instead of pressing buttons, the Firefly 2+ activates via two touch sensors on the sides. Place both thumbs on the sensors, wait 3 seconds — done. The heat-up time under 5 seconds is among the fastest for any convection portable. For comparison: the Mighty+ needs about 60 seconds, the Crafty+ around 90 seconds.

Touch activation has a practical advantage: no accidental starts in your pocket. Without touching both sensors simultaneously, nothing happens. The downside is battery life — the 770 mAh battery manages about 30-40 draws depending on temperature. That covers 4-6 bowls. Heavy users may find this limiting, but as an on-demand device, the Firefly is designed for short, targeted sessions rather than marathon use.

The vapor chamber and airpath are made from heat-resistant borosilicate glass — the same material used in lab equipment and high-end water pipes. Unlike stainless steel or plastic paths, glass adds zero taste of its own. The laser-cut micro-nozzles at the chamber base distribute hot air evenly across all material.

For flavor purists, the Firefly 2+ is particularly appealing. Terpenes at low temperatures (160-180 °C) come through clearly and distinctly. The chamber holds about 0.1-0.15 g of finely ground herbs — less than most session vapes, but perfect for on-demand use. Important: don't pack too tightly. Air needs to flow freely through the material, otherwise vapor production suffers noticeably.

The Firefly app (iOS and Android) allows stepless temperature adjustment between 150 and 260 °C. The device itself has no temperature display — only colored LEDs indicate charge level and ready status. For full control, the app is recommended, though after a while you'll find your favorite temperature and rarely need to change it.

Temperature tips: 175-195 °C works best for herbs — most terpenes unfold here. Above 200 °C, vapor gets denser but flavor diminishes. For concentrates (with the optional pad), 230-260 °C is recommended. The app also supports profiles for different temperature settings, which is handy when switching between herbs and concentrates.

The Firefly 2+ weighs 150 g — noticeably lighter than a Mighty+ (235 g) but heavier than pen-style vapes like the G Pen Dash+ (75 g). The body is made from magnesium alloy, which is both lightweight and durable. The lid is magnetic and removes easily for loading and cleaning.

The built-in 770 mAh battery charges via USB-C in about 45 minutes. Passthrough charging is not supported — you can't vape while charging. Battery life is the biggest trade-off: heavy users should bring a power bank. For the typical on-demand user taking 3-5 short sessions per day, a single charge is sufficient.

Besides dry herbs, the Firefly 2+ handles concentrates via a stainless steel pad that sits inside the chamber. At higher temperatures (230-260 °C), results are solid, though dedicated concentrate devices like the Dr. Dabber Switch 2 naturally perform better.

A water pipe adapter (WPA) is available as an accessory and fits standard 14 mm joints. Water filtration cools the vapor further, which is particularly pleasant at higher temperatures. Other accessories include replacement lids, a charging dock, and cleaning kits. Cleaning itself is straightforward: remove the lid, wipe the glass chamber with an isopropanol-soaked cotton swab, let dry. A deeper clean every 10-15 sessions is recommended.

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

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.
