It's tempting to think that a pod is a pod. But the differences matter for your customers:

• Battery capacity: 500mAh vs. 1500mAh is a huge difference in daily use.
• Coil resistance: Lower ohms (like 0.6) produce more vapor; higher ohms (like 1.2) give a tighter, more cig-like draw.
• Pod capacity: 1mL vs. 3mL means how often customers need to refill.
• Refillable vs. proprietary: Refillable pods let customers use any e-liquid; proprietary pods lock them into a specific flavor line.

Each of these affects the customer experience. A customer who wants a satisfying throat hit won't like a device with a 0.6 ohm coil. A customer who wants to save money won't want a device with expensive proprietary pods.
