Key Facts — Battery-Free Ganz The Dani Butane · Heating: Conduction · Heat-up: 15s

The portable The Dani uses conduction as its heating principle: the chamber wall is electrically heated and transfers the heat directly to the loaded material. Battery-Free Ganz thus delivers a straightforward vaporizer for quick sessions. The maximum temperature is 260 °C. Current prices in the price comparison.

How Portable and Ergonomic Is the Design?

The Dani fits comfortably in the hand and slips into any jacket pocket. Operation is via one or more buttons. The device heats the herbs in a ceramic or stainless-steel chamber via direct wall contact. Typical heat-up time: 20-40 seconds to operating temperature.

Research context: A study in the Journal of Pharmaceutical Sciences (Hazekamp et al., 2006) showed that vaporisation at controlled temperatures releases over 95 % of the desired active compounds whilst largely avoiding combustion by-products. Source: PubMed 16637053

← Back to Overview
Does the The Dani need electricity or a battery? +

No — the The Dani is battery- and cable-free and is heated with a torch lighter (butane gas).

Conduction or convection — which is better? +

Conduction heats up faster and is cheaper to manufacture. Convection often delivers cleaner flavour. Both have pros and cons — in the end it comes down to personal preference.
