Editor's verdict

What our editor thinks

If you’re a flavor snob who wants to dial things in, or you’re just a sucker for shiny displays and airflow options, the Uwell Caliburn G4 is a beast. The coils are much-improved, the flavor is great (though not quite in XROS 5 terrirory), and it looks and feels great in the hand.

Overview

What you need to know

Even though the Uwell Caliburn G4 is lightweight and compact, it’s absolutely stacked with smart features: 0.85in color screen, 3 slick menu themes, adjustable brightness and wattage, and two new power modes (Storm Mode and Wave Mode). It runs by a 1,300mAh battery and uses the new GPP pods with Uwell’s upgraded Pro-FOCS 4.0 coil tech for better flavor and 3x the longevity.

Pros, cons and standout features

What stood out in testing

If the G3 was already great (and it was), the G4 is like the fully-evolved final form. You get more power, better flavor, and actual customization — but yeah, it’s a bit bigger. What I Loved:

Flavor Is Top-Tier: That Pro-FOCS 4.0 coil tech really shows. Everything just tastes more — like crisper, cleaner, deeper.
Airflow Options Galore: You can slide it, flip it, or do both. Tighter MTL? Done. Looser RDL? Also doable.
Storm & Wave Modes: Want an intense hit? Storm Mode slaps. Prefer a smooth cruise? Wave Mode’s your guy.
Great Build Quality: It feels premium in the hand, and the display is actually useful (juice window = 10/10 feature).
