Flum Float Mello Pro 50K
Full Review & Comparison
50,000 puffs, Eco & Turbo dual mode, smart HD display — we tested it against the Geek Bar CLR 50K and Flum UT Bar 50K so you don't have to.

The Flum → Float Rebrand
If you've seen "Float" packaging where you expected "Flum," you're not looking at a knockoff. Flum (originally Flumigo Technology) rebranded its Float line as a distinct sub-brand — but the manufacturer, formulas, and quality standards are identical. Both names appear depending on a retailer's stock cycle.
Flum restructured into two focused product lines:
- Flum Mello Series — lifestyle-oriented, HD animated screens, ergonomic pebble design. Devices: Mello 20K and Float Mello Pro 50K.
- Flum UT Series — "Ultimate Taste" performance line. Dual mesh coils, turbo mode, industry-first dual-flavor switching. Devices: UT Bar Pro 25K and UT Bar Pro 50K.
Full Specs & Hardware
The device features a texturized PCTG body for grip, a soft mouthpiece built for extended sessions, and a smart color display showing exact battery %, e-liquid %, and current mode — eliminating the guesswork that plagues most disposables.
Eco Mode vs Turbo Mode
Eco Mode — The Marathon Runner
Fires a single coil at ~25W. Cooler vapor, smoother draw, the full 50,000-puff lifespan. Default mode for all-day use — less throat hit, consistent flavor, no fatigue over long sessions. Former smokers and newer vapers consistently rate Eco as the ideal starting point.
Turbo Mode — The Heavy Hitter
Activates both mesh coils simultaneously. Warmer, denser vapor, stronger throat hit — but puff count drops to ~25,000. Best used situationally. Fruit profiles like Peach Icy and Blue Razz Icy are notably enhanced in Turbo.
Airflow: The adjustable slider lets you dial from tight MTL to loose RDL. Sweet spot per reviewers: Level 1 airflow + Turbo Mode for an intense MTL experience that closely mimics a traditional cigarette.
All 10 Flavors — Tasting Notes
10 proven performers from the Mello catalog, optimized for the dual mesh setup. Eight carry over from the Mello 20K; two are 50K exclusives (★).
★ = Exclusive to the Float Mello Pro 50K
Sweet-tart berry hits first, followed by a sharp icy exhale. Top-selling Flum profile across all devices. Ice intensifies to a full blast in Turbo.
Arctic, no-nonsense mint. The go-to for former menthol cigarette smokers.
Spearmint with citrusy mojito undertones — lighter and breezier than Cool Mint, zero throat build-up.
Ripe, sugary peach nectar with a clean menthol finish. Notably elevated in Turbo Mode.
Green apple hard candy intensity with a menthol finish. Reviewers call it a "session stopper."
Classic summer watermelon + refreshing ice. Most consistent performer in the Flum catalog — safe first pick for newcomers.
Complex tropical fusion. Dual mesh coils deliver each note in layered sequence — technically impressive.
Pure nicotine delivery with zero taste. Rare in the disposable market. Highly valued by ex-smokers who dislike artificial fruit.
Tropical sour profile — tangy mango and bright pineapple. Fills a niche most 50K competitors ignore.
Strawberry-watermelon without menthol — unusual for the category. Warm, natural-tasting, full fruit expression.
Real User Reviews
Aggregated from flum-vape.com, Morevaping, VapePicks, and bigmosmokeshop.com.
"Former smoker. Wanted clean. The Clear flavor is perfect — no artificial taste. Went from Mello 20K to Pro 50K and it's just better in every way. Seeing exactly how much is left makes a huge difference."
"Three weeks in with Miami Mint and Strawmelon. The screen telling you exactly what's left is not a gimmick. Turbo mode for evenings, Eco for the commute. One complaint: the plastic body feels fine but not premium at this price."
"The smooth draw is the whole point. Blue Razz Icy is a standout. Flavor stays consistent right to the end — which is genuinely rare."
"Doesn't quite reach 50,000 puffs as advertised with daily heavy use — lasted a few weeks. Eco Mode helps it last longer; Turbo burns through it. Also: 5% only, no lower option."

Mello Pro 50K vs Geek Bar CLR 50K vs UT Bar 50K
All three sit at the premium tier of the 50K-puff segment. Here's how they actually differ.
| Feature | Float Mello Pro 50K | Geek Bar CLR 50K | Flum UT Bar 50K |
|---|---|---|---|
| Max Puffs | 50,000 | 50,000 | 50,000 |
| High-Power Puffs | ~25,000 Turbo | ~25,000 Pulse | ~25,000 Turbo |
| E-Liquid | ~20 mL | ~20 mL | Dual Tank ~20 mL |
| Tank Visibility | Opaque (screen) | Transparent (see liquid) | Opaque (per-tank screen) |
| Flavor Count | 10 | 15+ | 40+ |
| Flavor Switching | None | None | Dual-tank + Mix Mode |
| Draw Style | Smoothest / MTL | Balanced MTL/RDL | Warmer, performance-tuned |
| Unique Tech | Eco/Turbo dual mode | Transparent tank + VPU + 3D light | Dual-flavor switch + Mix Mode |
| Retail Price | $15–$25 | $22–$26 | $20–$25 |
| Per 1K Puffs | ~$0.40–0.50 | ~$0.44–0.52 | ~$0.40–0.50 |
| Best For | All-day smooth, ex-smokers, flavor consistency | Tech fans, visible liquid, bold flavor | Flavor variety seekers, power users |
You want the smoothest all-day draw, you're an ex-smoker, you vape MTL, or you want a Clean (unflavored) option. Best budget-to-longevity ratio.
You hate dry hits and want to see your liquid level, you prefer bold punchy flavors, or VPU vapor stabilization and 3D lighting matter to you.
You get bored vaping the same flavor for weeks. 40+ options with dual-tank switching and Mix Mode. Most feature-rich — but most complex to operate.
The Float Mello Pro 50K doesn't try to be the flashiest device on the shelf — it tries to be the best all-day companion, and it largely succeeds. Draw smoothness is class-leading in the 50K segment. The smart screen genuinely solves "how much is left?" anxiety. Eco/Turbo dual-mode delivers real flexibility. At $15–$25 with ~$0.40–0.50 per 1,000 puffs, it's one of the strongest values in premium disposables.
It loses points for a limited 10-flavor selection, no lower-nicotine option, and real-world puff counts that fall short of the 50K headline for heavy users. But for smooth-draw fans, ex-smokers, and anyone who wants a reliable daily vape that lasts weeks — it's an easy recommendation.
