KYRO uses inhale activation — the battery fires automatically when you draw. No button press needed, ever. The simplest possible operation for the widest range of end users.
No preheat, no voltage buttons, no controls — KYRO is the simplest device in the lineup. Ideal for end consumers who want zero friction.
KYRO measures Ø10.5 × 77mm and weighs just 15.1g — the smallest diameter and shortest length in the entire 510-thread battery lineup.
Slimmest and shortest battery in the lineup. KYRO MAX VV: Ø11.2 × 88.7mm / 19.6g. WINTER: Ø11.2 × 97mm / 20.8–25.4g. NOME: Ø14 × 82mm / 23.5g.
