Choose the UWELL Caliburn G4 Mini if:

- You prefer a buttonless, draw-to-fire experience
- You’re looking for an easy upgrade from disposables
Battery, Charging & Coil Life
Both kits come with a 520mAh internal battery – good for a full day of moderate vaping. They support USB-C charging, and a full top-up takes around 45 minutes. For best results, use a standard 1A wall adapter.
The G4 mesh coils last up to 7–10 days depending on usage and liquid type. Always use nic salt e-liquid or 50/50 PG/VG juice for optimal coil life.
Design, Leak Resistance & Build Quality
The G4 series introduces improved pod seals, making leaking far less likely. The top-fill pods snap open easily, so you can refill without getting e-liquid on your hands.
Build quality feels premium for both devices – especially the G4, which features a sturdier body and more advanced airflow engineering.

- Ex-smokers seeking a reliable nicotine salt vape
- Beginner vapers wanting an easy pod vape
- Disposables users looking for a cost-effective upgrade
