Flum UT 50K Disposable Vape — The First Dual-Tank 50K Disposable
Flum has been building flavor-first disposables since the early days of the category — but the Flum UT 50K is something the brand has never released before, and something no other major disposable brand has matched: a single device with two completely independent pre-filled tanks and a toggle switch that lets you flip between them mid-session. One device. Two flavors. 50,000 puffs. At $17.99, it's one of the more compelling value propositions in the high-puff category.
How the Dual-Tank System Actually Works
The Flum UT 50K ships with two separate e-liquid tanks built into the same chassis, each pre-filled with a different flavor. A dedicated toggle switch — plus two buttons beside the mouthpiece — lets you select which tank fires on your next draw. Switch is instant. No flavor bleed, no crossover taste, no re-priming needed. The digital screen shows which tank is active and displays each tank's remaining juice level independently, so you always know where both tanks stand.
Some flavor pairings are complementary — two fruity profiles that blend naturally when you alternate. Others are deliberately contrasting — a sweet profile on one side, a cool minty finish on the other. Either way, the practical benefit is real: it solves flavor fatigue, which is one of the most common reasons vapers burn through disposables too quickly.
Eco Mode or Turbo Mode — Pick Your Output
Eco Mode is where the 50,000-puff figure comes from. Smooth, efficient, and built for all-day sessions where longevity matters more than intensity. Turbo Mode roughly halves the puff count to approximately 25,000 puffs, but delivers a noticeably warmer, denser vapor with bolder flavor presence. Most vapers use Eco for everyday sessions and Turbo when they want a more intense hit.
Flum UT 50K Flavor Pairings
Each Flum UT 50K ships with one pre-selected flavor pair. Fruity pairings include combinations like Cherry Strawberry Gummy / Passion Fruit Mango, Wild Berry Drops / Aloe Grape, and Strawberry / Banana Smoothy. Mint and ice pairings offer options like Miami Mint on one side with a tropical or berry profile on the other for vapers who want to switch between cool and sweet. Beverage-style profiles round out the catalog for vapers who want something beyond standard fruit blends.

Everything Else the UT Vape Flum Gets Right
Beyond the dual-tank innovation, the Flum UT 50K runs a solid hardware spec: a 760mAh USB-C rechargeable battery, dual mesh coils (one per tank, keeping flavor profiles fully separate), adjustable airflow via a manual switch, and a digital display showing battery life and each tank's juice level simultaneously. Draw-activated — no buttons needed for everyday use. And yes, the clear pouch on the device is decorative liquid, not e-liquid — a design detail Flum added to the form factor.

The Flum UT 50K is Flum's flagship high-puff disposable and the first Flum device to feature a dual-tank system.

It's the most advanced Flum vape available.
How do I switch flavors on the Flum UT 50K?
There are two buttons located beside the mouthpiece — one for each tank. Press the button corresponding to the tank you want to activate.
