Flum Float Mello Pro 50K Disposable Vape

The Mello Pro 50K carries 30mL — the largest single tank on our entire pocket-device shelf, comfortably above the 16–20mL that 50K rivals run. That is not a rounding difference: fifty percent more liquid than a typical 50K means the same rated puff count arrives with margin to spare, and for pure milliliters per dollar at $24.99, nothing here beats it.

The reserve feeds dual mesh coils through Eco and Turbo modes — endurance or density, the usual trade — with an HD color display keeping battery and level honest, adjustable airflow to set the draw from tight to open, and a 1000mAh cell on USB-C fast charging that recovers quickly between sessions. In Eco mode, expect the top end of the three-to-five-month band at moderate use, on 5% (50 mg/mL) salt throughout.

The flavor program is the house identity: Mello-series smooth — rounded, low-edge, low-ice profiles built for all-day use rather than first-puff shock, a deliberate step away from the candy-forward end of the market. Nine flavors are live today from the 13-variant catalog. If the UT Bar Pro is Flum's showpiece and the Clear Tank its transparency play, the Mello Pro is the endurance pick: the most liquid, the calmest flavors, the longest runway.

Nine Mello Pro flavors ship today, all in the house style — smooth first, ice second. Miami Mint and plain Menthol hold the cool end without going throat-numbing, Watermelon Peach Lime and Strawmelon do the layered-fruit work, and the "Icy" builds — Blue Razz Icy, Sour Apple Icy, Peach Icy, Watermelon Icy — run colder but stay rounded. Sour Mango Pineapple is the sharpest thing on the menu, and by most brands’ standards it is still mellow. Pick any of them for all-day rotation; that is what the line is tuned for.
