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.
