UWELL Caliburn Bar S18000

The Uwell Caliburn Bar S18000 offers up to 18,000 puffs with a 22 mL e-liquid capacity and 5% nicotine strength. It features an 800 mAh battery, dual 1.2-ohm coils, and a digital display showing battery and e-liquid levels. The device supports Regular Mode (16W) and Boost Mode (22W) with one-touch voltage and airflow adjustment.

The Caliburn BAR S18000 is a box-style disposable with rounded edges and a centralized, wide-bore duckbill mouthpiece. It measures 101.5 x 47 x 22.6 mm and is comparable in size to the notably large BLVK Bar. Yet somehow, the Caliburn BAR S18000 feels much more svelte in the hands.

The bodies are colored-transparent cases made of PCTG and aluminum, decorated with symmetrical steampunk artwork—like a mechanical Rorschach test. I enjoy the aesthetics of these devices. They’re playful and intriguing to look at without being too toy-like. Overall, I’d say they’re tastefully designed.

On the front panel of the S18000 is an embossed plate that displays the branding of “KOKO,” another one of UWELL’s products. The feeling of that plate adds a nice variation in texture from the glossy plastic body.

As an aside, I think the device's name could be hard to remember. I think that’s an unforced error from UWELL. The device has the “KOKO” branding and “Dual Coil Flagship.” But nowhere on the device does it say S18000. On the back, it says “CaliBARn.” I get what they’re trying to do there, but I think it unnecessarily adds to the confusion.
