Geek Bar vs Lost Mary: quick comparison

*Puff counts are manufacturer best-case estimates from internal testing. Real-world puff count depends on draw length, chosen mode, airflow and charging habits. Prefer flavor over specs? See the Lost Mary Ultrasonic 35K further down.

The brands in one line each

Geek Bar is the tech-forward brand: pioneering Pulse Mode, big 3D curved screens and some of the highest puff counts on the market. Its flagship, the Geek Bar Pulse X 2 50K, is Vape101's #1 disposable. Read our full Geek Bar Pulse X 2 review for the deep dive.

Lost Mary is the flavor-first brand: smooth, refined profiles and a huge menu, with 2026 hardware that broke new ground. Its Ultrasonic 35K is our best-overall pick in the best disposable vapes of 2026 guide, and editorial site Vaping360 called it the must-try disposable of 2026.

Puff count and runtime: it depends which Lost Mary

Against the Ultrasonic 35K, Geek Bar wins on raw numbers. The Pulse X 2 50K claims up to 50,000 puffs in Regular Mode — well ahead of the Ultrasonic's 35,000. But Lost Mary has a puff-count flagship of its own: the Lost Mary VIZ 55K claims up to 55,000 puffs in Normal Mode (30,000 in Boost), which actually edges out the Geek Bar. So if pure longevity is what you're after, the real fight is Pulse X 2 50K vs VIZ 55K.

The VIZ backs that number with triple-layer atomization (three mesh coils), a 360° visible tank, an immersive LED lighting ring and an LED display for battery, e-liquid and mode — Lost Mary's most tech-forward device yet, and its answer to Geek Bar's screen. Editorial site Vaping360's VIZ product breakdown has the full spec sheet.

That said, all of these are marathon devices. A vaper averaging 200–300 puffs a day will get weeks out of any of them, and the Ultrasonic's larger 20mL tank helps it punch above its puff rating in real terms. If maximum longevity is the priority, look at Geek Bar's 50,000+ puff disposables or the Lost Mary VIZ; if 35K is plenty, the flavor advantage below may matter more.

Flavor: Lost Mary's new trick vs Geek Bar's bold hit

This is where the two brands truly diverge. Geek Bar's dual mesh coil and VPU flavor system push a saturated, punchy draw — icy fruit, candy and beverage blends land bold and immediate. If you like a flavor that hits hard from the first puff, Geek Bar delivers.

Lost Mary went a different way. The Ultrasonic 35K pairs a traditional dual mesh coil with ultrasonic atomization, splitting its 20mL across a main mesh tank and three smaller ultrasonic flavor tanks you switch between with a flavor wheel. The result, per Versed Vaper's hands-on review, is an unusually smooth, clean and layered taste that stands out even among premium disposables. Geek Bar is louder; Lost Mary is more refined.

Design and display: screen vs subtlety

Geek Bar makes the screen a headline feature. The Pulse X 2's 3D curved starry smart screen shows battery, e-liquid level and active mode at a glance, with animated visuals that make it feel like a pocket gadget. If you want a device with personality, Geek Bar owns this category.

Lost Mary keeps things cleaner. The Ultrasonic 35K has clear battery and e-liquid indicators plus its flavor wheel, but a smaller footprint and more understated look. The Lost Mary MT35000 Turbo takes this further with a "blend-in" display that stays hidden until you draw, then lights up. If you prefer a lower-profile device that isn't shouting for attention, Lost Mary is the pick.

Battery and charging

Both charge over USB-C and both are rechargeable, which is essential to reach these puff counts. Geek Bar runs a larger ~1000mAh cell to feed its higher-output coil across a longer life, while Lost Mary's Ultrasonic 35K uses an 800mAh battery paired with its more efficient atomization. In practice, both keep up with a full day of use — always use the recommended cable, avoid damaged cords and never leave a vape charging unattended.

The head-to-head: Pulse X 2 50K vs VIZ 55K

Spec for spec, the Lost Mary VIZ 55K is the truest rival to the Pulse X 2 50K. It claims up to 55,000 puffs in Normal Mode (30,000 in Boost) from a 16.7mL tank and an 850mAh USB-C battery, and it uses triple-layer atomization — three mesh coils — to feed that runtime. Where Geek Bar answers with its 3D curved screen, Lost Mary counters with a 360° see-through tank, an immersive LED lighting ring and an LED display for battery, e-liquid and mode. Vaping360's VIZ breakdown has the full spec sheet.

In short: the VIZ narrowly wins on headline puff count and has the more eye-catching transparent design, while the Pulse X 2 has the larger tank, the bigger battery and Geek Bar's signature bold, saturated flavor. Both are premium flagships — this one comes down to whether you want a see-through Lost Mary or a screen-forward Geek Bar. If flavor smoothness matters more than either, the Ultrasonic 35K is still the taste champion, and the value-focused MT35000 Turbo covers the budget end of Lost Mary's range.

Which should you buy?

• Buy Geek Bar (Pulse X 2 50K) if: you want the longest runtime, the biggest screen, a bold saturated hit and dual modes. Best for heavy users and anyone who loves tech-forward devices.
• Buy Lost Mary (Ultrasonic 35K) if: flavor is your top priority. Its ultrasonic hardware delivers the smoothest, best-tasting draw we've tested this year, in a cleaner-looking device.
• Buy Lost Mary (VIZ 55K) if: you want Lost Mary's flavor and the highest puff count here, plus a see-through 360° tank and LED display. It's the model that goes toe-to-toe with the Pulse X 2 on runtime and tech.
• Want simpler or lower-profile? Geek Bar's screen-free Pulse 15000 or Lost Mary's MT35000 Turbo are the understated picks.

Adult customers should also review Vape101's shipping, return and age requirements before ordering. For general, non-commercial background on nicotine and e-cigarettes, see the FDA's ENDS overview.
