Before you build your kit, check these basics:

• Device size: A pod-style model is usually the sweet spot—smaller than a box mod, but still with enough juice for a day.
• Battery capacity: Look for something in the 350–500 mAh range if you're a light user, or go higher if you vape more often. That should cover a typical workday.
• Airflow control: You want the option to tighten the draw—this cuts vapor volume and makes it more discreet.
• Charging: USB-C is the norm now, but make sure you have a cable at your desk or in your bag.
• Carry case: A small hard case with padding protects the device and any spare pods.
• Local rules: Check whether vaping is allowed where you work and in public spaces. Some places have restrictions.
