When you're evaluating a pod system, the best thing you can do is test it yourself. But you also need to verify the specs on paper. Here's a checklist:

• Battery capacity (mAh): Higher is better for all-day use.
• Charging time: Some devices charge in 30 minutes, others take 2 hours.
• Coil resistance (ohm): Determines the draw and vapor production.
• Pod capacity (mL): How often do customers need to refill?
• Refillable or proprietary: Which suits your customer base?
• Safety certifications: Look for CE, RoHS, FCC markings.
• Build quality: Does it feel solid? Does the pod sit flush?

Use the Windbar tools to crunch the numbers. The Vape Cost Calculator helps you compare the long-term cost per puff across different devices. The Vape Battery Calculator estimates battery life based on specs and usage habits. These aren't just for consumers—they're useful for you too.
