Flum UT Bar Vape

The UT Bar is Flum's slab-shaped disposable line

Where the Flum Mello is the rounded "bottle" silhouette, the Flum UT Bar Vape is the flat slab — a wide, pocketable rectangle with a Mega HD screen across the face. Every UT Bar runs on dual mesh coils and USB-C charging, and all three models share the same shape so accessories and the in-hand feel carry across the family.

What changes between models is the engineering play: the Clear Tank 50K adds a transparent window so you can see the juice; the UT Bar Pro 50K splits the tank in two so you can vape two flavors and switch between them mid-session (how that compares with other dual flavor disposable vapes is its own guide); the UT Bar Pro 25K trades the second tank for adjustable airflow and a Smooth/Turbo power toggle. If you're comparing the UT Bar against the rest of the brand, the quick read is on the Flum UT vs Flum Mello guide.

Single-flavor UT searches cluster around a handful of names: Sour Straws UT and Mango Tango UT on the Clear Tank 50K, Watermelon Sour Peach UT and Tropical Rainbow Blast UT on the UT Bar Pro 50K. Each has its own page with the taste profile and live stock. The rest of the single-flavor UT names people search for — Passion Kiwi Pineapple UT, Mexican Mango UT, Peach Mango Watermelon UT, Green Apple Ice UT and Frozen Watermelon Flum — are listed the same way. Comparing the slab against another brand's dual-flavor or 50K device? The Uwell vs Flum and Geek Bar rows on the brand comparison page cover that.
