The VOPK COOL BAR 9000 is a 9,000-puff device with 15ml behind it, adjustable airflow and a 1.0Ω mesh coil. What makes it unusual for a wholesale line is the sample box option: one carton bundling the taste range, so a shop can test before committing to a mix.

The sample box is the feature

Ordering a new line usually means guessing which options will move. The sample box removes the guess: a single box covering the taste range, one unit each. You can work through the box, find what you like, and buy that one in quantity next time.

For a first order that is worth more than a discount, because the cost of a wrong option mix is stock that sits.

Adjustable airflow at 9K

The airflow ring moves between a tighter mouth-to-lung draw and a more open one. At this capacity the device is usually bought by someone who already knows how they like to draw, so being able to set resistance rather than accept it is a real difference.

The 600mAh cell recharges over USB-C, and 15ml is generous for the rating — most 9K devices carry 12 to 14ml.

Technical specifications

Figures reflect the current product record.

Values reflect the current product record. Puff counts are manufacturer ratings and vary with draw length and frequency.

One strength, one decision

Strength is fixed at a single setting, which removes the most common ordering question on a line like this: there is one version to stock and the only variable is the option mix. If you already use several multi-strength devices, that simplicity is worth something.
