The RELX Infinity Plus is a closed pod device, so it runs on pre-filled pods rather than e-liquid you add yourself. The pods hold 1.9 mL and come pre-filled with salt nicotine, which suits the tight, cigarette-style draw most people switching from smoking are after. RELX puts a lot into the pod design, with a leak-proof build and an ergonomic mouthpiece that's comfortable to use, and the device shows its battery level through LED lights so you're not caught out. It charges over USB-C. The appeal here is simplicity and a clean, considered feel: you click in a pod, vape, and replace it when it's empty, with nothing to refill or maintain. It's a sensible choice for someone who wants a tidy, low-effort device and likes the RELX pod range.
