Built-in 1200 mAh battery: Provides extended use between charges. Maximum output of up to 25 W: Allows for a broader range of e-liquid types and vaping styles (from moderate MTL to loose RDL). Compatible with all G3-series cartridges (0.6 Ω / 0.9 Ω / 1.2 Ω) — so you have flexibility between freebase liquids and nicotine salts. 360° view window: Lets you easily check your e-liquid level without removing the pod. Dual airflow system: Gives the option to adjust airflow for a tighter or looser draw. U² Anti-leak Mechanism (Ultrasonic Welding + U-shaped channel) inside the pod design: Helps reduce leakage significantly — touted at ~150% enhancement vs other systems. Pro-FOCS Flavor Technology: Uwell’s flavor-optimization tech, aimed at delivering richer flavor in each puff. Auto-draw (draw-activation): You can vape without pressing a button — just inhale. Fast charging via USB-C (on some listings) and LED indicators for battery level.
