About this vaporizer

The Dani Fusion 2.0 from Battery-Free Ganz is a German-made butane convection vaporizer built around a simple idea: ditch the battery entirely. A butane torch heats a glass bowl, convection draws hot air through your herb, and the vapour goes directly into a water pipe attachment. No charging, no firmware, no battery degradation over time.

Battery-Free Ganz targets users who are genuinely tired of managing battery life or who simply want a device that works wherever there's butane — off-grid, while travelling, anywhere. The convection heating approach means the material is never in direct contact with a hot surface, which gives you clean, flavour-preserving vapour. Temperatures can reach up to 260°C, though most sessions will be much lower for optimal taste.

Heat-up is about 60 seconds — you light the torch, let the bowl heat, and the warmth builds before you start drawing. Once at temperature, the session is smooth. The water pipe compatibility is central to the design: the cooling and filtration from even a small water piece makes the vapour noticeably more comfortable to inhale.

The glass components are user-replaceable and easy to clean. Two years of warranty come with the device. For someone who's specifically interested in butane-powered vaporizers and values the water pipe integration, the Dani Fusion 2.0 is a technically coherent and well-thought-out option from an unusual corner of the market.

The Dani Fusion 2.0 by Battery-Free Ganz (BFG) is a high-calorie mechanical pen vaporizer that operates entirely without batteries or electronics. Its hybrid heating combines roughly 80% convection with 20% conduction, delivering dense, flavor-rich draws from the very first heat cycle.

What makes the Dani Fusion stand out: the stainless steel cap houses two silver rings that store an enormous amount of heat. Silver conducts heat better than any other metal, so you don’t even need to rotate the device while heating. The titanium tip, Vietnamese rosewood stem, and titanium mouthpiece make the Fusion 2.0 one of the highest-quality mechanical vaporizers available – at a price that sits more than 100 EUR below comparable devices.

How It Works: Design and Mechanics

The Dani Fusion 2.0 is a mechanical vaporizer with no battery or electronics. Heat is applied externally – either with a jet lighter or the BFG Flare induction heater. At its core sits the stainless steel cap with two embedded silver rings that serve as a high-calorie heat reservoir.

Silver has the highest thermal conductivity of any metal. The rings distribute flame heat instantly and evenly across the entire cap. A built-in click mechanism provides audible feedback when the optimal temperature is reached.

The vaporizer disassembles completely into its individual parts: cap, tip, CCD screen, O-rings, stem, and mouthpiece. Every component is individually replaceable.

Materials and Build Quality

BFG uses exclusively premium materials for the Dani Fusion 2.0:

Cap: Stainless steel with two embedded silver rings – the heat reservoir
Tip: Grade 2 titanium – lightweight, corrosion-resistant, heat-tolerant
CCD screen: Stainless steel – fine-mesh, durable
Stem: Vietnamese rosewood with internal stainless steel liner – insulates heat, protects the wood
Mouthpiece: Titanium – hygienic and taste-neutral
O-rings: Viton – heat and chemical resistant up to over 200°C

Compared to competitors like the DynaVap or Tempest, the Dani Fusion 2.0 costs a good 100 EUR less – with comparable or better material quality. A leather carrying case is also included, which doubles as heat protection when removing the hot cap.

Stem Options and Airflow

The Dani Fusion 2.0 offers four different stem options that vary in material and length:

Long wood stem: Vietnamese rosewood with stainless steel liner and intercooler – cool, smooth vapor
Short wood stem: More compact, warmer vapor, great for on-the-go
Metal stem: Stainless steel, rugged and easy to clean
Pipe-style stem: Ergonomic, reminiscent of a classic pipe

All stems are compatible with 10mm and 14mm water pipes. Inside the long wood stem sits an intercooler that further cools the vapor.

Airflow is steplessly adjustable at the tip via dual bore holes. Rotating the tip opens or closes the air channels – from fully closed (maximum resistance, densest vapor) to wide open (free airflow, lighter hits).

Heating Methods: Jet Lighter and BFG Flare

The Dani Fusion 2.0 can be powered by two different heat sources:

Jet Lighter

The simplest and most portable method. Thanks to the silver rings in the cap, you don’t need to rotate the Dani while heating – the heat distributes itself. Flame position controls the temperature:

Flame at the bottom of the cap: Hotter extraction, denser vapor
Flame at the top near the silver ring: Cooler extraction, more flavor

One heat cycle is enough for a complete extraction. For a more leisurely experience, you can also clear the chamber over two cycles.

BFG Flare Induction Heater

The optional BFG Flare is an induction heater with 120 watts of power. Heat-up time: around 20 seconds. It uses 31650 cells and has an adjustable ceramic insert to customize the heating position (and thus the temperature). The Flare offers a flameless, wind-independent alternative to lighters.

Cleaning and Maintenance

The Dani Fusion 2.0 is straightforward to clean thanks to its fully disassemblable design. The key is treating metal and wood parts separately:

Metal Parts (Cap, Tip, CCD Screen, Mouthpiece)

All metal components can be soaked in isopropyl alcohol (ISO). Brief soak, rinse, let dry. Remove the Viton O-rings first.

Wood Stem

The rosewood must not be soaked in ISO. Instead:

Run an ISO-soaked pipe cleaner through the stainless steel liner
Wipe the exterior with a slightly dampened Q-tip
Regularly condition with wood wax or wood oil

O-Rings

Treat the Viton O-rings occasionally with a bit of silicone grease or Dynawax. This keeps them supple and extends their lifespan.

Recommended schedule: Tap out the chamber after each session. Full metal parts cleaning every 1–2 weeks.

Frequently Asked Questions

What is a high-calorie vaporizer? +

A high-calorie vaporizer uses materials with high heat storage capacity as a heat reservoir. In the Dani Fusion 2.0, two silver rings in the stainless steel cap fill this role. Silver has the highest thermal conductivity of any metal and stores enough energy for consistent hits without performance drop-off.

How is the Dani Fusion 2.0 heated? +

Two options: With a jet lighter (portable, no rotation needed) or the BFG Flare induction heater (120W, about 20 seconds heat-up, flameless). With the lighter, flame position controls the temperature: bottom = hot, top near the silver ring = cooler.

What does the click mean? +

The Dani Fusion 2.0 has a built-in click mechanism. The click signals that optimal operating temperature has been reached. You can start drawing immediately after the click. When it clicks again during cool-down, it’s time to reheat.

How large is the chamber? +

The chamber holds 0.14 g of material. That is enough for one or two heat cycles. For complete extraction in one cycle: pack firmly and hold the flame a bit longer. For two cycles: pack loosely, first draw at lower temperature.

What stem options are available? +

Four options: Long wood stem (rosewood, intercooler, coolest vapor), Short wood stem (compact), Metal stem (stainless steel, rugged), and Pipe-style stem (ergonomic). All fit the same tip and work with 10mm/14mm water pipes.

Does the Dani work with water pipes? +

Yes. The Dani Fusion 2.0 fits 10mm and 14mm water pipes. Simply insert the stem into the joint. Water filtration cools the vapor further and makes particularly hot hits much more pleasant.

How do you clean the Dani Fusion 2.0? +

Metal parts (cap, tip, screen, mouthpiece) can be soaked in isopropyl alcohol and rinsed. The wood stem should not be soaked in ISO – instead, run an ISO-soaked pipe cleaner through the inner liner and wipe the outside with a Q-tip. Condition the wood regularly with wood wax.

What is the BFG Flare? +

The BFG Flare is an induction heater by Battery-Free Ganz. It heats the Dani cap via induction in about 20 seconds (120 watts). It uses 31650 battery cells and has an adjustable ceramic insert to customize the heating position. Flameless, wind-independent – the more comfortable alternative to lighters.

Does the Dani Fusion 2.0 work with an induction heater like the YLL 3.0? +

Yes. The Dani Fusion 2.0 is compatible with the YLL 3.0. Recommended settings are 100 W with 43–45 seconds heat-up time. The Dani's massive stainless steel heating element takes a bit longer than lighter devices like DynaVap.
