Flum vs Other Vape Brands — How the Lineups Compare
We only stock Flum, so treat this as an honest description of what Flum's lineup does and where other brands sit in the same market — not a scorecard. The useful comparisons are format, puff tier, flavor breadth and what a device actually costs per 1,000 puffs.
Flum runs 7 devices from 20,000 to 60,000 puffs in three formats — sealed bottle, sealed slab and a pod-swap system. Most of the brands people compare against Flum sit in one of two different camps: other sealed high-puff disposables (Elf Bar, Geek Bar, Fresor), or refillable and closed-pod hardware (Uwell, Smok, Juul, Blu). Which camp you want matters far more than which logo is on the device.
What we can and can't compare
We sell one brand. That means we can be precise about Flum — the numbers in the table below are pulled from the same product data that runs our checkout, so they cannot drift out of date — but we are not in a position to bench-test another company's hardware and tell you it fell short. Anywhere this page describes another brand, it is describing the category and the publicly published specification, nothing more.
We also will not tell you whether a device you found somewhere else is genuine. We have no way to inspect it, and guessing would be worse than useless. What we can say is what we do on our own stock: every inner box is scratch-code scanned before we accept the pallet, and we do not re-package, re-label or sell open-box units. The full detail is on our about page.
The lineup, for reference
Everything below is measured the same way, so the cost-per-1,000-puffs column is the honest way to compare a cheap low-puff device against an expensive high-puff one.
| Device | Format | Puffs | Flavors | Price | Per 1K puffs |
|---|---|---|---|---|---|
| Float Ryzo 60K Kit | Pod-Swap Kit | 60,000 | 12 | $24.99 | $0.42/1K |
| Float Ryzo 60K Pods | Replacement Pod | 60,000 | 12 | $19.99 | $0.33/1K |
| UT Bar Clear Tank 50K | Clear-Tank Disposable | 50,000 | 11 | $24.99 | $0.50/1K |
| UT Bar Pro 50K | Dual-Tank Disposable | 50,000 | 43 | $24.99 | $0.50/1K |
| Mello 20K | Standalone Disposable | 20,000 | 33 | $23.99 | $1.20/1K |
| Float Mello Pro 50K | Standalone Disposable | 50,000 | 13 | $24.99 | $0.50/1K |
| UT Bar Pro 25K | Adjustable Disposable | 25,000 | 20 | $23.99 | $0.96/1K |
Puff ratings are manufacturer figures measured at a standard draw. Real-world numbers depend on how you vape — longer draws and higher-power modes pull the count down on any brand's device.
Geek Bar vs Flum
Worth clearing up first, because this gets searched both ways: Geek Bar is Geekvape's disposable brand, launched in 2019 to sit alongside the reusable mods and tanks the parent company is known for. So "Geekvape vs Flum" and "Geek Bar vs Flum" are usually the same question — sealed disposables against sealed disposables — and it is the Geek Bar side of the house that lines up against our range.
This is the closest like-for-like comparison, because both brands are built around sealed high-puff devices. Geek Bar's published 2026 lineup spans roughly 15,000 puffs on the original Pulse up to 60,000 on the Mate, with the Pulse X2 at 50,000 sitting in the middle, and the Mate is notable for separating the battery from the e-liquid rather than sealing everything into one body.
That last point is where the interesting overlap is. Flum's answer to the same idea is the Float Ryzo 60K: the base recharges and stays with you, and the 60,000-puff pod — coil sealed inside — is what you replace. If you like the economics of keeping the hardware and swapping only the consumable, both brands now offer a route to it. Flum's running cost after the kit is the replacement pod, not a whole new device.
If you would rather not think about pods at all, the sealed comparison is Flum's UT Bar Pro 50K, which is a slab with two tanks you click between mid-session — a format neither of the sealed Geek Bar devices offers.
Elf Bar vs Flum
Elf Bar is the higher-volume brand of the two by a wide margin, and its lineup has climbed fast: the BC5000 is now the legacy device, with the Ice King rated at 30,000 puffs, the EBCREATE BC Pro at 40,000, and an FS70K announced for 2026 at up to 70,000 puffs on triple mesh coils.
On raw puff ceiling, Elf Bar's newest announcements sit above anything in the current Flum range. Where Flum is competitive is flavor depth on a single device — the Mello 20K alone carries 33 flavors across 6 themed editions, including a floral set and a mint-based City Series that have no direct equivalent elsewhere. If you rotate flavors constantly, breadth on one platform is worth more than another 20,000 puffs you will not notice.
The other practical difference is tier spacing. Flum's range is deliberately narrow and each step is a different format rather than just a bigger number — bottle, dual-tank slab, pod swap. Elf Bar's is wider and more incremental.
Fresor
Fresor vs Flum is usually a price-led question. Fresor is a smaller sealed-disposable brand, and the comparison worth making is the per-1,000-puffs column in the table above rather than the sticker price: a cheaper device with a lower puff rating often costs more per puff than a dearer one, and that is the number that decides what you actually spend over a month.
Uwell
Uwell vs Flum is a category mismatch, and that is the answer. Uwell built its reputation on refillable pod systems — the Caliburn line above all — where you buy the device once and keep buying coils and e-liquid separately. Flum makes sealed, pre-filled devices.
So the real question is not which brand is better, it is whether you want to maintain a device. Refillable systems are cheaper per millilitre and let you choose any e-liquid; they also mean coil changes, refills and carrying a bottle. Flum's trade is the opposite: no maintenance and a fixed flavor per device, at a higher cost per millilitre. If you have never owned a refillable and want to try one, that is a genuine reason to look at Uwell rather than at us.
Smok
Smok vs Flum is the same category gap, further along. Smok is primarily a mod-and-tank hardware brand — adjustable wattage, replaceable coils, user-selected e-liquid. That is a hobbyist route with a real learning curve and the widest customisation of anything mentioned on this page.
Nobody cross-shops a Smok mod and a Flum bottle on specification. They get compared because someone is deciding whether to step up into hardware or stay with something sealed. If you want to tinker, Flum has nothing for you. If you want to pick a flavor and not think about it again, the Mello 20K is the least demanding thing in our range.
Juul
Juul vs Flum comes down to size against endurance. Juul is a closed-pod system: a small rechargeable body with sealed pods, designed around discretion and a low-profile draw rather than puff count. Its pods hold a fraction of what a modern high-puff disposable carries, so a Juul is replaced or recharged far more often across the same amount of vaping.
People searching Juul against Flum are usually weighing size against endurance. Juul wins comfortably on pocketability. Flum's devices are physically larger in every case, and what you get for the bulk is the tank — 20,000 puffs at the low end of our range.
Blu
Blu vs Flum plays out much like Juul. Blu is one of the older names in the category and sits in the same closed-pod and cigalike space as Juul, with a similar emphasis on a small, simple device. The comparison plays out the same way: minimal format and low capacity on one side, sealed high-puff devices with broad flavor menus on the other.
If you are coming off a cigalike and the main complaint is how often it needs attention, that is the specific problem the high-puff format was built to solve.
Mello, Float Pro or UT Bar?
A good share of "vs" searches are not about other brands at all — people are trying to work out the difference between the Mello and the Float Mello Pro, or between the UT Bar and the Mello. Those share a family name and genuinely are confusing. We split them apart properly in the UT vs Mello vs Float Pro comparison, which covers puffs, modes, screen and price across the three lines side by side.
The short version: Float Mello Pro is the 50,000-puff flagship of the Mello family, the Mello 20K is the smaller bottle with by far the deepest flavor menu, and the UT Bar line is the slab-shaped family with the dual-tank trick on the 50K. The full flavor index covers every device.
Frequently asked
01 Is Flum better than Elf Bar? +
Neither is better across the board, and we would not be the right people to ask anyway — we only stock Flum. Elf Bar's newest announcements reach a higher puff ceiling; Flum's strength is flavor depth on one platform, with the Mello 20K carrying 33 flavors on a single device. Decide on format and flavor range rather than on brand.
02 Which brand lasts the longest? +
Compare cost per 1,000 puffs rather than the puff rating alone, since a high number on an expensive device can work out worse than a lower one on a cheap device. Within the Flum range that figure starts at $0.33/1K on the Float Ryzo 60K Pods; the table on this page lists every device.
03 Does Flum make a refillable vape? +
No. Every Flum device is sealed and pre-filled. The closest thing in the range is the Float Ryzo 60K, which is a pod-swap system — you keep the rechargeable base and replace the pod, coil included — but you are still not filling anything yourself. If you want a refillable pod system or a mod, that is a different category of product entirely.
04 How do I know a Flum device I bought elsewhere is real? +
We cannot tell you that, because we have not handled it. Flum prints a scratch-off security code on the inner box that you can check on Flum's own verification page, and that is the right place to confirm any device regardless of where it came from. What we can account for is our own stock: we scan the inner-box codes before accepting a pallet and never re-package or re-label.
05 What is the difference between Flum and Flum Float? +
They are the same brand. "Flum Float" is the product family name — the Float Mello Pro 50K and the Float Ryzo 60K both sit under it — so searches for Flum, Flum Float and Float Mello all point at the same catalogue. The UT Bar line is the other half of the range.
06 Do you sell any brand other than Flum? +
Not on this store. This site carries the Flum range only, which is why this page describes other brands by category and published specification rather than reviewing them.
