TL;DR
The Geek Bar Pulse X 25K is the 2026 successor to the original Geek Bar Pulse and one of the highest-puff-count regulated disposables on the U.S. market. Geek Bar lists 25,000 puffs in Regular Mode and 15,000 in Pulse Mode, an 18 mL e-liquid reservoir with 5% (50 mg) nicotine salt, dual mesh coils, an 820 mAh USB-C rechargeable battery, and a 3D-curved LED screen showing battery and e-liquid levels. The Pulse X 25K's distinctive feature is a switchable two-mode system: Regular Mode optimizes for puff count and battery life, while Pulse Mode roughly doubles wattage for stronger flavor and cloud production. Lucky Vape Store stocks the full Pulse X lineup; the device is one of the most-shipped disposables in the catalog.
Verdict: If you want the highest puff count from a single disposable while keeping the option to switch into a higher-output flavor mode for the last few hundred puffs of a flavor session, the Pulse X 25K is the most polished implementation of that formula in 2026. It is heavier than older disposables and the price point is at the premium tier ($14.99–$19.99 typical), but per-puff cost is the best in the category. Compared head-to-head with the Lost Mary MT15000 Turbo, the Pulse X has more puffs but the MT15000 Turbo edges out on flavor consistency in the second half of the device.

What's in the box
- 1 × Geek Bar Pulse X 25K disposable device, pre-charged and pre-filled
- Manufacturer documentation (warning insert, brief use guide)
- Tamper-evident seal and authentication scratch-off code on the outer packaging
A USB-C cable is not included. Most buyers already have a USB-C cable on hand from a phone or laptop charger; if not, any standard USB-C cable will charge the device.
Build quality and design
The Pulse X 25K body is a soft-touch plastic shell with a translucent reservoir window. Hand-feel is heavier than the original Pulse — the larger battery and 18 mL reservoir add noticeable weight versus a 5,000-puff device. The 3D-curved LED screen on the front is the visual standout: it shows battery percentage, e-liquid level, and the currently selected mode. The mode toggle is a small button below the screen.
The mouthpiece is a standard duckbill shape with a slight downward angle. Airflow adjustment is via a sliding ring at the base. The USB-C charging port is on the bottom and oriented vertically — most buyers find this convenient; a small minority prefer side-port designs for use while charging.
Construction quality is consistent with Geek Bar's recent product line. Out of dozens of units handled at Lucky's Coral Gables flagship, no out-of-box defects (leaks, dead batteries, screen failures) have been reported through May 2026.
Flavor lineup
The Geek Bar Pulse X 25K is available in roughly 46 flavors as of May 2026, spread across the standard lineup plus three special editions (Slush Edition, Jam Edition, Meteor Edition). The strongest sellers in Lucky's catalog are listed below with brief tasting notes; this is not the full lineup, but the flavors most likely to actually be in stock at a U.S. retailer.
- Miami Mint — clean spearmint with a slight chill on exhale; the closest the lineup gets to a pure mint flavor.
- Blue Razz Ice — classic blue raspberry with menthol; sweet on inhale, cool on exhale.
- Sour Apple Ice — tart green apple with a moderate menthol finish.
- Strawberry B-Pop — strawberry candy with a subtle sour note; sweeter than the Sour Apple.
- Watermelon Ice — straightforward watermelon with light menthol; one of the most consistent picks across modes.
- White Peach Raspberry — peach-forward with a raspberry top note; fruit-forward without being candy-sweet.
- Cool Mint — sharper menthol than Miami Mint; closer to a tobacco-replacement mint profile.
- Sour Fcuking Fab — Geek Bar's signature mixed-berry flavor with a sour candy edge; one of the better-reviewed flavors in the lineup.
- Pear of Thieves — pear with a faint apple finish; one of the more unusual flavors in the standard lineup.
- Strawberry Jam (Jam Edition) — sweeter and more candy-like than Strawberry B-Pop; closer to a dessert profile.
- Peach Jam (Jam Edition) — heavy peach jam with a cream finish; one of the dessert-leaning flavors.
- Cola Slush (Slush Edition) — cola with menthol; tastes like a cola Slurpee.
- Wild Cherry Slush (Slush Edition) — cherry candy with menthol; closest to a Cherry Coke profile.
- Grape Slush (Slush Edition) — grape candy with menthol; sweeter than the standard Grape Ice.
The full 46-flavor lineup includes additional fruit, candy, dessert, and mint variants. Stock varies by retailer; Lucky's Pulse X collection page shows current availability.
Performance test
This section reflects observations from devices used at Lucky's Coral Gables flagship for evaluation purposes; manufacturer-stated specifications are noted separately above.
First 50 puffs. The Pulse X starts strong out of the box. Flavor on the first draw is full and consistent with what each flavor profile suggests. In Regular Mode, vapor production is moderate; in Pulse Mode, vapor production is noticeably heavier. There is no break-in period — the first puff is comparable to puffs 50 and 100.
Mid-tank consistency. Around the midpoint (roughly 12,000–15,000 puffs into a Regular-Mode-only session), flavor remains consistent. The dual-mesh coil maintains saturation noticeably better than single-mesh designs in older 10K–15K-puff disposables. There is no detectable burnt taste in standard use.
End of life. The last 1,000–2,000 puffs are where the Pulse X separates from older Geek Bar designs. Earlier disposables tended to lose flavor sharpness in the last 10% of the reservoir; the Pulse X holds flavor better, though there is a slight reduction in sweetness near the end. The on-screen e-liquid indicator is reasonably accurate within ±10%.
Throat hit. 5% nicotine salt; throat hit is moderate-to-firm. Switching to Pulse Mode increases throat hit noticeably — buyers who find 5% nic harsh may prefer to stay in Regular Mode.
Cloud production. Regular Mode produces moderate clouds appropriate for indoor use without drawing attention. Pulse Mode roughly doubles cloud volume — closer to a sub-ohm tank than to a typical disposable.
Battery life and recharge. The 820 mAh battery does not last 25,000 puffs on a single charge — buyers should expect to recharge multiple times over the device's life. A full charge from empty takes roughly 45–60 minutes via USB-C. The screen shows charge progress.
Geek Bar Pulse X 25K vs alternatives
| Device | Puffs | E-liquid | Battery | Modes | Standout |
|---|---|---|---|---|---|
| Geek Bar Pulse X 25K | 25,000 / 15,000 | 18 mL | 820 mAh | Regular + Pulse | Highest puff count + dual mode |
| Lost Mary MT15000 Turbo | 15,000 | 16 mL | 600 mAh | Smooth + Turbo | Best mid-tank flavor consistency |
| Lost Mary MO20000 | 20,000 | 19 mL | 600 mAh | Single mode | High puff count, simpler UX |
| RAZ TN9000 | 9,000 | 12 mL | 500 mAh | Single mode | Compact form factor, screen |
Vs Lost Mary MT15000 Turbo: The Pulse X has 67% more puffs but the MT15000 Turbo holds flavor more consistently in the second half of the device. The MT15000 Turbo's Smooth/Turbo mode pair is functionally similar to Pulse X's Regular/Pulse pair. For buyers who finish a disposable in two weeks, the MT15000 Turbo's lower per-unit price often makes more sense; for buyers who want the longest-running single device, the Pulse X is the pick.
Vs Lost Mary MO20000: The MO20000 is simpler — single mode, no dual-coil — and slightly less expensive. Buyers who don't use mode switching often find the MO20000 a better value.
Vs RAZ TN9000: The RAZ TN9000 is a different category — smaller, fewer puffs, more pocketable. Not really a head-to-head comparison; the buyer either wants compactness (RAZ) or longevity (Pulse X).

Frequently asked questions
Is the Geek Bar Pulse X 25K rechargeable?
Yes. The internal 820 mAh battery is rechargeable via USB-C. The device is not refillable — once the 18 mL reservoir is empty, the device is finished.
How long does 25,000 puffs really last?
That depends entirely on usage. A heavy daily user (300–400 puffs/day) finishes the device in roughly 8–9 weeks of Regular Mode use. A casual user (100 puffs/day) gets closer to 6 months. Pulse Mode use shortens the lifespan because each draw consumes more e-liquid.
Are all Geek Bar disposables 5% nicotine?
The U.S. Geek Bar Pulse X 25K is sold at 5% (50 mg) nicotine salt. Lower-nicotine variants exist in other markets and in some Geek Bar product lines (the Pulse X DTL variant is sold at 0.5% in some markets), but the U.S. mainline Pulse X 25K is 5%.
What's the difference between Regular Mode and Pulse Mode?
Regular Mode optimizes for puff count and battery life — lower wattage, longer-running. Pulse Mode runs the dual-mesh coil at higher wattage, producing more vapor, stronger flavor, and a firmer throat hit, at the cost of fewer total puffs (15,000 in Pulse Mode vs 25,000 in Regular Mode if the device is run exclusively in one mode).
How do I switch between modes?
Tap the small button below the LED screen. The active mode is displayed on the screen.
Does the device come with a charger?
No. Buyers need a standard USB-C cable. Any phone or laptop USB-C cable works.
How can I tell if my Geek Bar Pulse X 25K is authentic?
The outer packaging includes a scratch-off authentication code. Geek Bar's official authentication portal at geekbar.com accepts the code and returns an authenticity result. Counterfeit Pulse X devices have been reported in the U.S. gray market — buying from an authorized retailer (Lucky Vape Store, Element Vape, VaporDNA, MyVaporStore, and similar) is the most reliable counterfeit-avoidance step.
Is the Pulse X 25K sold in nicotine-free?
Not in the U.S. mainline. The U.S. version is sold at 5% nicotine salt only.
Does the device leak?
Out of the box, no — the reservoir is sealed and the dual-coil design keeps wicking saturated. Some leakage at the airflow ring has been reported when the device is stored mouthpiece-down at high temperatures (above 100°F / 38°C); standard practice is to store the device upright or on its side.
What's the warranty?
Geek Bar's manufacturer warranty covers manufacturing defects; the warranty process runs through the authorized retailer. Lucky Vape Store handles defective-device returns within 14 days of delivery; defects past 14 days are processed through Geek Bar's manufacturer warranty.
Verdict
The Geek Bar Pulse X 25K is the most polished version of the high-puff-count disposable formula in 2026. Dual-mesh coils, a working dual-mode system, a useful on-device screen, and the highest puff count in the category make it the obvious pick for buyers who want a single device to last as long as possible. The premium price and the heavier hand-feel are the trade-offs. Lucky Vape Store stocks the full lineup at competitive pricing with a $25 free-shipping threshold; first-order customers can stack LUCKY10 for additional savings.
