Flum Float Mello Pro 50K — 30ml Tank with Eco and Turbo Modes
The Flum Float Mello Pro 50K is Flum's highest-capacity disposable to date, packing 30ml of e-liquid into a single device rated for up to 50,000 puffs. It merges the smooth flavor profile that the Mello series is known for with the dual mesh coil technology from the UT Bar Pro line. Two firing modes — Eco at 25W and Turbo with both mesh coils active — let you choose between extended battery life and maximum cloud production.
The HD color display tracks battery level, e-liquid percentage, and current mode in real time. Adjustable airflow adds another layer of control, letting you switch between a tight MTL draw and an open RDL pull without any accessories. At $24.99, the Mello Pro 50K delivers the most e-liquid per dollar in the Flum lineup. Compare it against the UT Bar Pro 50K — same puff count, different flavor DNA.

Why Choose the Mello Pro 50K
30ml Tank — Industry-Leading Capacity
Most 50K-puff devices carry 20–25ml of e-liquid. The Mello Pro packs 30ml, which translates to denser flavor saturation and more vapor per puff. You get more out of each device before replacement.
Eco vs Turbo — Battery Intelligence
Eco Mode runs at 25W using a single mesh coil, stretching battery life and liquid for maximum puff count. Turbo Mode fires both mesh coils simultaneously for thicker clouds and warmer, more intense flavor. Switch between them based on whether you are conserving or cloud-chasing. For charging specifics, see our Flum charging guide.
Adjustable Airflow
The built-in airflow toggle lets you go from a tight mouth-to-lung draw (ideal for high-nicotine sessions) to a restricted direct-lung pull (better for cloud production). This range covers both ex-smokers and experienced vapers.
HD Color Display
The screen shows battery percentage, e-liquid level, and active mode. It removes the guesswork that comes with blind disposables and helps you plan recharges before the device dies mid-session.
Smooth Draw — Mello Series DNA
The Mello Pro inherits the smooth, low-irritation draw that the Mello series is known for. Reviewers note that the throat hit is mild even at 5% nicotine, making this a good choice for vapers who prefer comfort over harshness.
