The Dani from Battery-Free Ganz is a German-developed butane gas vaporizer with line heating that does not require a battery or charging adapter. With a maximum temperature of 260 °C and 15 seconds heat-up time, it delivers quick sessions with a torch lighter. Water pipe compatibility is integrated - a rare feature in pure butane devices - and a 2-year guarantee underlines the quality.
The portable The Dani relies on conduction as its heating method: the chamber wall is electrically heated and transfers warmth directly to the packed material. Battery-Free Ganz keeps things simple with fast heat-up times and easy loading. Maximum temperature reaches 260 °C. Current prices in the price comparison.

Research context: A study in the Journal of Pharmaceutical Sciences (Hazekamp et al., 2006) showed that vaporisation at controlled temperatures releases over 95% of target compounds while largely avoiding combustion by-products. Source: PubMed 16637053
With conduction, material is heated through direct contact with a hot surface. With convection, hot air flows through the material. Convection is considered more efficient and flavorful.
For optimal performance, we recommend light cleaning after each session and thorough cleaning with isopropyl alcohol every 1-2 weeks.
170-185C for light vapor, 185-200C for balanced effects, 200-210C for maximum extraction. Start low and work your way up.
