Navigating RELX’s product lineup requires understanding key differences between models. Here’s a concise comparison to guide your choice:
Core Generations
- Alpha: The foundational series (Alpha, Alpha S). Reliable battery life & classic design. Prioritizes consistent flavor delivery.
- Infinity: Step-up featuring SmartPace™ vibrate alerts after 15 puffs. Sleeker aesthetic, improved coil tech for flavor clarity.
- Phantom: Premium tier. Largest batteries (SuperX & Ultra variants) & flagship performance. Introduced Turbo mode.
Design & Build
Phantom LITE stands out: significantly lighter weight & matte finish. Infinity models typically offer a slightly slimmer profile vs. classic Alpha.

Battery Performance
- Alpha: Approx. 370mAh.
- Infinity/Infinity 2: Approx. 380mAh.
- Phantom: ~400mAh (SuperX ~490mAh). Phantom Ultra boasts the largest at ~495mAh. Translate to longer use per charge.
Key Functions
- SmartPace™: Infinity & Phantom models vibrate gently after 15 consecutive puffs (reminder, not a hard limit). Alpha lacks this.
- Turbo Mode (BoostMax™): Exclusive to Phantom SuperX/Ultra. Button-activated for intensified flavor & vapor for 10 seconds. Requires compatible pods.
- Display: Only Phantom Ultra features an LED battery level indicator.
Pod Compatibility
All RELX pod systems (1:1 connection) are cross-compatible across Alpha, Infinity, & Phantom generations. Pod performance may vary slightly based on device power output. Turbo Mode requires Phantom Turbo pods.
Target User
- Alpha: First-timers & value-seekers desiring core RELX experience.
- Infinity/Infinity 2: Users wanting subtle refinement, SmartPace™, & a slimmer feel.
- Phantom LITE: Prioritizes ultra-light portability.
- Phantom SuperX/Ultra: Enthusiasts demanding max battery life & optional intense power boost (Turbo). Ultra adds battery display.
Choose Alpha for essentials, Infinity for refined basics, Phantom LITE for lightness, or Phantom SuperX/Ultra for extended use & peak performance with Turbo.
