About this vaporizer
The Zenco Duo Stone is the grey colour version of the Zenco Duo, a versatile vaporizer that combines 510 cartridges, dry herbs and concentrates in one device. Stone is not a limited edition but one of four colours permanently offered alongside Wood, Onyx (black) and Leaf (green). Technically all four variants are identical. The Duo uses conduction heating and, instead of a degree figure, offers four voltage levels from 2.5 to 4.0 volts to match intensity to the material. An auto-fill function and two included glass attachments round out the equipment, and the battery has 2,200 mAh. Anyone looking for a flexible multi-material device in a plain grey look is well served by the Duo Stone.

No. Stone is one of four permanently available standard colours (alongside Wood, Onyx and Leaf). There is no artificial scarcity — the colour is purely a matter of taste.
The Duo is a multi-material device: it handles 510 cartridges, dry herbs and concentrates in a single device.
Instead of a temperature setting in degrees, the Duo uses four voltage levels from 2.5 to 4.0 volts. A lower voltage produces milder draws, while a higher voltage produces denser vapour.
No. All four colour variants (Wood, Onyx, Stone, Leaf) are technically identical. The only difference is the colour.
The Duo includes an Auto-Fill function for concentrates and two glass attachments for different draw experiences. The battery has a capacity of 2,200 mAh.
