RELX Infinity 2 Review: Specs, Flavour & Battery Life
Quick Verdict
The RELX Infinity 2 is a closed-system pod device that focuses on one thing: a smooth, reliable, grab-and-go experience. With its classic pen-style silhouette, a 440 mAh battery and the signature RELX smart-puff algorithm, the Infinity 2 is one of the easiest devices to pick up and just vape. It is not a cloud machine and it is not designed for tinkering — it is a premium-feeling, low-hassle pod for anyone who wants consistent flavour with zero fiddling. For smokers transitioning to vaping and for anyone who values simplicity above all else, the Infinity 2 is a standout.
Key Specifications
| Spec | Value |
|---|---|
| Battery | 440 mAh (internal) |
| Max output | ~6 – 11 W (adjustable modes) |
| Pod capacity | 1.9 ml — up to ~600 puffs |
| Charging | USB-C, ~80% in 15 minutes |
| Draw | Auto-draw |
| Modes | Adjustable 3 power settings |
The numbers here are deliberately modest — RELX is not chasing wattage records. Instead, the spec sheet reflects a design philosophy built around efficiency and consistency. A 440 mAh battery managed by a smart chipset, a 1.9 ml pod, and a handful of power settings is everything a convenience-first device needs, and nothing it does not.
Design and Build Quality
The Infinity 2 keeps the slim, cylindrical pen shape that made RELX famous — minimalist, discreet and genuinely comfortable to hold. The finish is smooth and refined, with no sharp edges, and the pod snaps securely into place with no wobble. It is the kind of device that looks and feels far more expensive than it is, and it slinks easily into a shirt pocket or a small bag.
The build quality extends to the little details: the mouthpiece is shaped to rest comfortably on the lips, the pod is easy to see through so you know when it is running low, and the whole thing feels solid with no creaks or rattle. It is clear that RELX has refined this form factor over several generations, and the Infinity 2 is the polished result.
Performance and Flavour
RELX devices are built around their proprietary puff-activation system, which monitors draw length and adjusts power in real time to keep the vapor smooth and consistent. The Infinity 2 continues this with a familiar, warm and smooth MTL hit that is easy on the throat. Flavour transfer from RELX’s prefilled pods is clean and accurate, and the three power modes let you tune the warmth and volume to your preference. It is not a cloud-chaser — it is a flavour machine in the truest sense.
The smart-puff algorithm is the secret weapon here. Rather than a fixed output, the Infinity 2 varies its power based on how you draw, which keeps every puff smooth and even, whether you take a short sip or a long pull. This results in a remarkably consistent experience that avoids the harshness or dryness that plague many disposables on a long draw.
Airflow and Features
As a closed system, the Infinity 2 is refreshingly simple — no refilling, no coil changes, no leaks. You snap in a prefilled pod, vape until it runs out, and swap in a fresh one. The adjustable modes are the only real control, which is exactly the point for a device aimed at convenience-first vapers. The auto-draw is responsive and consistent, with no lag or misfires.
Battery and Charging
The 440 mAh battery is modest on paper but RELX’s efficient chipset makes it go further than the number suggests. In real-world testing the Infinity 2 held up for an impressive 14 hours of continuous use on the lowest setting. USB-C charging is fast — around 80% in about 15 minutes — so even a quick top-up during the day keeps you going.
That real-world battery life is a huge part of the Infinity 2’s appeal. Because the low-power modes sip energy so efficiently, most users will only need to charge every day or two under normal use. And when you do need a shot of power, the fast USB-C charging means a quick break is all it takes to get you back to full.

Comparison: RELX Infinity 2 vs Other Pods
Compared to the Elf Bar ELFX, an open-system pod, the Infinity 2 trades refillability and wattage for pure simplicity and a lighter carry. The Freemax Galex Nano 2 offers a bigger battery and far more coil options, but it requires you to refill and change coils. The Infinity 2 is the pick if you want the absolute least-effort experience and prefer prefilled pods.
| Model | Battery | System | Pod | User type |
|---|---|---|---|---|
| RELX Infinity 2 | 440 mAh | Closed prefilled | 1.9 ml | Convenience-first |
| Elf Bar ELFX | 1000 mAh | Open refillable | 2 ml | Performance-first |
| Freemax Galex Nano 2 | 900 mAh | Open refillable | 3 ml | Flavour-first |
Who Should Buy the RELX Infinity 2
The Infinity 2 is made for convenience-first vapers and for smokers making the switch. If you want a device you can charge and forget, pop in a prefilled pod and vape without a second thought, this is it. It is also a great travel companion and an unobtrusive office device — small, quiet and discreet. What you give up is flexibility: there is no refilling, no coil choice and no high-power option, and prefilled pods cost more per puff than refillable systems over the long run. If you are happy to trade that for a streamlined, premium experience, the Infinity 2 delivers exactly what it promises. If you are a heavy vaper who prefers customisation, an open-system pod will suit you better.
Final Verdict
The RELX Infinity 2 is a masterclass in simplicity. It does not try to be the most powerful or the most configurable pod on the market — it aims to be the most effortless, and it succeeds. If you value a smooth, reliable draw, a premium feel and zero maintenance, and you prefer prefilled pods, the Infinity 2 is a superb daily companion. It is a device that simply gets out of your way and lets you enjoy the vape.
