- Ceramic Coil: Premium smoothness (used in STLTH, Elf Bar)
- Mesh Coil: Enhanced vapor production

Fun Fact: JUUL’s patented heating wick uses porous ceramic to prevent dry hits.

2.2 The Battery & Control Module

Battery Capacity: 350mAh (average for mini-pods)
Smart Features:
- Pogo Pin Connectors: Magnetic pod attachment
- Airflow Sensors: Auto-draw activation (no buttons)
- Temperature Control: Prevents overheating

Section 3: Cotton vs. Ceramic Coils – Which is Better?

Feature	Cotton Coils	Ceramic Coils
