These features combine to create a disposable vape that caters to a wide range of vaping preferences, from mouth-to-lung (MTL) to restricted lung hits.

Design and Ergonomics

The Caliburn BAR S12000 showcases a sleek and modern design that sets it apart from other disposable vapes on the market. The device features a box-style body with rounded edges and a centralized, wide-bore duckbill mouthpiece, ensuring a comfortable and enjoyable vaping experience.

The device is constructed using high-quality PCTG and aluminum materials, with a colored-transparent body that allows you to monitor your e-liquid level at a glance. The exterior is adorned with symmetrical steampunk artwork, adding a touch of artistic flair without appearing overly flashy or toy-like.

One notable design element is the embossed “KOKO” branding plate on the front panel, which adds a pleasant textural variation to the glossy plastic body. While the device’s official name, “S12000,” is not prominently displayed on the product itself, the “CaliBARn” branding on the back serves as a subtle nod to the Caliburn family of vapes.

Getting Started and Operation

Using the Caliburn BAR S12000 is a breeze, even for those new to vaping. To get started, simply remove the device from its packaging, along with the protective plugs. Locate the slide switch on the bottom of the device, which also functions as an integrated airflow control. This switch allows you to toggle between two power modes and adjust the airflow to your liking:

  • Regular Mode: 16W power output, slightly loose MTL draw
  • Boost Mode: 22W power output, restricted lung hit

It’s important to note that the switch also features an “off” position, located in the middle, which prevents accidental activation when the device is not in use.

One minor drawback is the lack of a visual indication of the current power mode on the device’s smart LED screen. However, with the screen facing you and the device oriented upright, the Regular mode is accessible by sliding the switch to the left.

Battery Life and Longevity

The longevity of the Caliburn BAR S12000 largely depends on the power mode you choose. When using the device in Regular mode, you can expect the 800 mAh battery to last longer, allowing you to enjoy up to one tick of the e-liquid meter per full charge. However, opting for the Boost mode will result in faster battery drainage and increased e-liquid consumption, a trade-off for the enhanced performance.

Charging the device is a simple process, thanks to the included USB Type-C charging port. It takes approximately 70 minutes to charge the device from 0% to 100%, with the smart LED screen prominently displaying the charging status throughout the process.

Performance and Vaping Experience

The Caliburn BAR S12000 delivers a remarkable vaping experience, thanks to its advanced Flagship Dual Coil atomization system. This 1.2-ohm dual coil technology ensures that each coil fires independently, resulting in enhanced flavor production and consistently impressive performance.

When vaping in Regular mode, you’ll notice a smooth and flavorful draw, accompanied by a low-pitch hum from the coil. Switching to Boost mode intensifies the experience, providing a warmer, more potent, and flavorful vape, with only the slight sound of rushing airflow.

The adjustable airflow control allows you to further customize your vaping experience, catering to your preferred draw style and intensity. Whether you favor a loose MTL draw or a restricted lung hit, the Caliburn BAR S12000 has you covered.
