IQOS ILUMA i One vs ILUMA i: Which Should You Buy in 2026?
Share
Choosing between the IQOS ILUMA i One and the IQOS ILUMA i? Both are the latest generation IQOS devices in 2026 — but they have a key structural difference that makes one better suited for different types of users. This complete comparison breaks down everything you need to know.
The Core Difference: One-Piece vs Two-Piece
The fundamental difference between the two devices is their physical design:
- IQOS ILUMA i One — A single-unit all-in-one device. The battery and heating chamber are in one piece. Charges directly via USB-C. Insert stick, use, remove — no separate components.
- IQOS ILUMA i — A two-piece system consisting of a holder (where the TEREA stick goes) and a pocket charging case. The holder charges inside the case between sessions.
