Puff counts are marketing nonsense. No lab test can tell you exactly how many puffs you'll get, because it depends on how long and hard you inhale. Ignore those numbers. Instead, think about your own usage. If you take quick 2-second puffs, a smaller battery might last longer than you think.

Also, remember that vapor production isn't purely about size. A compact device with a mesh coil can produce surprisingly dense vapor. But you'll sacrifice battery life for that performance. There's no free lunch.
