Flum UT 50K Vape — Dual Flavor, Eco & Turbo Mode, 50,000 Puffs

What Makes the Flum UT 50K Special

The Flum UT 50K is the first disposable vape from Flum to hit 50,000 puffs — and it does it with a twist. This device carries two separate flavor tanks inside one body. Pick a dual-flavor combo and switch between them with one tap. No other 50K device gives you this kind of variety in a single unit.

With 17mL of total e-liquid, dual mesh coils, and a 2.01-inch HD display, the Flum UT 50K is one of the most feature-packed disposable vapes on the market right now.

Eco Mode vs Turbo Mode

The Flum UT 50K gives you two ways to vape:

• Eco Mode — up to 50,000 puffs. Smooth, efficient output for all-day use. The device manages power automatically for consistent flavor and maximum longevity.
• Turbo Mode — up to 25,000 puffs. Cranks up the power to the dual mesh coils for denser vapor and bolder flavor. You feel the difference on the first draw.

Eco Mode is your daily driver. Turbo Mode is for when you want bigger clouds and stronger hits. Switch anytime — the dual mesh coils handle both without losing flavor quality.

Dual Flavor — Two Tanks, One Device

This is what sets the Flum UT 50K apart from every other 50K vape. Each device holds two independent e-liquid tanks with their own dedicated mesh coils. That means zero flavor cross-contamination.

Two buttons on top let you adjust the intensity of each flavor across three strength levels. You can make one flavor dominant and the other subtle, or switch them off entirely. That gives you up to 12 possible flavor combinations from a single device.

25+ Flavor Combos to Explore

The Flum UT 50K comes in 25 dual-flavor combinations and 15 single-flavor options. Here are some standout dual combos:

• Blue Razz Ice / Triple Berry — sweet-tart blue raspberry meets a rich mixed berry blend
• Mango / Strawberry — tropical mango paired with classic ripe strawberry
• Cool Mint / Icy Mint — a breezy sweet mint on one side, a deep freeze on the other
• Strawberry / Watermelon Icy — two best-selling fruit flavors in one palm-sized device
• Green Apple / Fuji Apple — crisp sour apple meets sweet Fuji in a fresh combo
• White Peach / Raspberry — juicy peach layered with tart raspberry sweetness
• Banana Smoothie / Strawberry — creamy banana blended with a bright strawberry finish
• Sour Fab / Citrus Ice — sour candy paired with a frosty citrus kick

More dual combos include Aloe Grape / Aloe Watermelon, Blue Razz / Lemonade, Miami Mint / Mint Slushy, Passion Fruit / Mango, Thai Mango / Juicy Peach, Watermelon / B-Pop, White Peach / Lemon Head, and Naked / Spring Water. Single-flavor options include Mexican Mango, Blue Razz Ice, Strawberry Watermelon, Tropical Rainbow Blast, and more. Browse our full disposable vapes collection for even more options.

2.01-Inch HD Display

The Flum UT 50K features a 2.01-inch HD screen — one of the largest displays on any disposable vape. It shows your battery percentage, e-liquid level for both tanks, and current power mode in real time.

The screen updates as you vape so you always know exactly where you stand. No guessing when you're running low on juice or battery.

Battery and Charging

The Flum UT 50K runs on a 760mAh rechargeable battery with USB-C charging. A full charge takes about 45-60 minutes.

In Eco Mode, a full charge lasts for hundreds of puffs before you need to plug in. Turbo Mode drains the battery faster, so expect to charge more often if you run it hard. The 2.01-inch display shows your exact battery percentage so you always know when to charge.

How Long Does the Flum UT 50K Last?

With 17mL of e-liquid split across two tanks and up to 50,000 puffs, here's what to expect:

• Light vaper (casual, social) — up to 5-6 weeks in Eco Mode
• Average vaper (moderate daily use) — about 3-4 weeks in Eco Mode
• Heavy vaper (all-day use) — 1-2 weeks in Eco Mode, less in Turbo Mode

The dual-tank design means you can switch flavors throughout the day without carrying a second device. That's real convenience for vapers who like variety.

Flum UT 50K vs VIHO TRX 50K

The Flum UT 50K wins on dual-flavor switching and display size — no other 50K device lets you carry two flavors in one unit. The VIHO TRX 50K takes the lead on battery size and coil tech. Both are top choices in the 50,000-puff tier.
