Every compact vaporizer has the same basic parts, but the size changes how they behave.

• Battery – The power source. Smaller devices often have smaller batteries, meaning more frequent charging.
• Chamber (or tank) – Where the CBD oil or dry herb sits. Compact chambers hold less, so you'll refill more often.
• Heating element – Wicks or coils that vaporize the liquid. In compact pens, these are often small and can clog faster.
• Mouthpiece – The part you inhale from. Often the first thing to break or get gunked up.
• Airflow control – Some models let you adjust draw resistance, but on tiny devices this might be a fixed slot.
