Geek Bar Pulse X 25K Review — The Geek Bar We Recommend Most

If the original Pulse proved that disposable vapes could be smart, the Pulse X proves they can be refined. The jump from 15K to 25K puffs matters — but it's not the headline. The real story is three upgrades that change the daily experience: an enhanced dual mesh coil operating at 25W in Pulse Mode (vs the original's 20W), a 3D curved screen that wraps around the body and makes the original's flat panel look dated, and what Geek Bar calls "AI-powered flavor tuning" — a calibrated power curve that adjusts output for each specific flavor profile.

That last claim is the one I tested most aggressively. AI is a loaded term in 2026, and when a disposable vape manufacturer uses it, skepticism is reasonable. So I ran the Pulse X side-by-side against the original Pulse on three identical flavors (Miami Mint, Watermelon Ice, Sour Fcuking Fab) and against the RAZ LTX 25000 — its most direct competitor at the 25K-puff tier. The results were clear enough to form a recommendation, even if "AI" remains a generous description of what's happening inside.

The 3D Curved Screen — More Than Aesthetics

The Pulse X's screen is the most immediately obvious upgrade over the original Pulse, and it's genuinely impressive. Geek Bar calls it a "Curved CNC Display Board" — a 3D curved LED panel that extends from the front face around both sides of the device body. In Regular Mode, the side panels display a slowly drifting starfield animation. In Pulse Mode, constellations form and an animated "X" sphere pulses on the front. The display is bright — distractingly so in dark environments, and there's no dimmer option.

Functional information is the same as the Pulse: battery percentage, e-liquid level, and mode indicator, all in single-percentage increments. The curved format doesn't add informational content — it adds visual real estate. Whether that matters depends on whether you view a disposable vape as a tech accessory or a utility tool. The screen does draw more battery than the Pulse's flat panel, which partly explains why the 820mAh battery doesn't extend charge cycles as much as the raw capacity increase would suggest.

Compared to the RAZ LTX 25000's screen: The RAZ's 1.77-inch HD display is a traditional flat panel, but it has two features the Pulse X lacks: a dark mode toggle (press the button to dim the screen for discrete use) and a wattage readout that shows exactly how many watts are being delivered. The Pulse X tells you which mode you're in; the RAZ tells you the actual power output. Both screens track battery and juice in precise increments. If you want the most visually striking display, the Pulse X wins by a wide margin. If you want the most useful display, the RAZ's dark mode and wattage readout arguably edge ahead.

AI Flavor Tuning — Separating Marketing From Mechanics

This is the claim that required the most scrutiny. Geek Bar states the Pulse X uses "AI-powered flavor tuning" that adjusts output for each flavor profile. Here's what I could determine through testing and cross-referencing industry reviews:

What it appears to be: Pre-programmed power curves calibrated for different e-liquid compositions. Fruit profiles, mint profiles, and candy profiles have different optimal vaporization temperatures. The VPU (Vapor Processing Unit) dual-core chip in the Pulse X stores heating curve data and adjusts the coil's power ramp accordingly. This is closer to "firmware calibration per SKU" than "artificial intelligence" — but the result is measurable.

What I tested: I ran Miami Mint, Watermelon Ice, and Sour Fcuking Fab on both the Pulse X and the original Pulse, both in Pulse Mode. The differences were subtle but consistent across all three units:

The honest assessment: The AI tuning produces real, if modest, improvements — most noticeable on complex multi-layer profiles (Sour Fcuking Fab, Banana Taffy Freeze) and least noticeable on simple single-note profiles (Watermelon Ice, Cool Mint). Whether "AI" is the right term is debatable. But the flavor output is measurably refined compared to the original Pulse running the same juice formulations, and that's what matters. MiPod's review noted the same: the Pulse X "hits harder" and "draws out the flavors" compared to the original, attributing it to both the upgraded 25W coil and the calibration system.

Power Upgrade: 12W/25W vs 10W/20W

The Pulse X increases wattage by 20-25% across both modes: Regular jumps from 10W to 12W, and Pulse jumps from 20W to 25W. The 25W Pulse Mode is the most significant change. At 20W, the original Pulse's Pulse Mode felt like "Regular Mode but louder." At 25W, the Pulse X's Pulse Mode feels like a different device entirely — warmer, denser, with vapor production that approaches what you'd expect from a refillable pod system operating at similar wattage.

The drawback: the higher wattage in both modes means the 820mAh battery doesn't stretch as far as you'd expect from a 26% capacity increase over the Pulse's 650mAh. MiPod's comparison noted the same finding — the Pulse X's bigger battery "does not allow for much additional vaping between charges as the wattage is higher." In practice, I got 1.5-2 days between charges at moderate use (~400 puffs/day, mixed modes) vs the Pulse's ~1 day. An improvement, but not a dramatic one.

The enhanced dual mesh coil also benefits from the higher wattage. At 25W, the coil runs warmer and vaporizes liquid more completely per puff, which results in more flavor extraction. Fruit flavors especially benefit — the extra heat brings out volatile flavor compounds that the Pulse's 20W coil doesn't fully activate.

Flavor Lineup: 46+ Options Across 9 Editions

The Pulse X carries fewer flavors than the original Pulse (46+ vs 54+), but the editions are more diverse in concept. The Pulse is all fruit-candy-menthol. The Pulse X adds Slush, Jam, and Thermal editions that expand the flavor philosophy into slushy drink profiles, jam/preserve profiles, and temperature-play profiles respectively.

Notable additions over the Pulse: The Slush Edition introduces slushy-drink profiles (Cola Slush is a genuine soda flavor — rare in disposables). The Jam Edition offers fruit-preserve sweetness that's different from the standard candy-fruit approach. The Platinum Edition wraps the device in stainless steel for a premium-feel variant. These editions fill gaps that the original Pulse's lineup left open — though the Pulse X still lacks true dessert/bakery profiles.

Top picks from testing: Sour Fcuking Fab (the AI tuning difference is most apparent here), Banana Taffy Freeze (complex candy-banana-ice layering that rewards Pulse Mode), Miami Mint (reliable #1 seller that tastes slightly more refined on the X), and Cola Slush (a genuine novelty — actual cola fizz sensation that's unique across all brands).

Same-Brand Comparison: Pulse X vs Every Other Geek Bar

The upgrade math from Pulse to Pulse X: You pay $5-7 more and get 67% more puffs, 26% more battery, 12% more e-liquid, 25% more wattage in Pulse Mode, AI flavor calibration (exclusive to this model), and a 3D curved screen. You lose 8 flavors (54+ drops to 46+). By pure cost-per-puff, the Pulse X is a better deal: roughly $0.88/1K puffs vs $1.10/1K for the Pulse. The only scenario where the Pulse is the smarter buy: you specifically want one of the ~8 flavors (Zodiac series, some Frozen variants) that didn't carry over to the X.

The CLR at $2-3 more: Here's the trickier comparison. The CLR 50K costs only slightly more and doubles the puff count. But it has only 14 flavors, no AI tuning, and a less impressive screen. The CLR trades flavor breadth and tech sophistication for raw longevity and a transparent tank. If you burn through devices quickly, the CLR's math wins. If you care about flavor quality and variety, the Pulse X remains superior.

Cross-Brand Comparison: Pulse X vs RAZ LTX 25000

This is the 25K-puff tier's defining matchup. Both devices were designed to be the flagship all-in-one disposable for their respective brands, and they target the same buyer: someone who wants more than 15K puffs without jumping to a modular/kit system. The specs are remarkably close, but the design philosophies diverge sharply.

Where the Pulse X wins: More e-liquid (18ml vs 16ml — a 12% advantage that translates to 2-3 extra days of use). Higher Pulse wattage (25W vs 24W — minor but measurable). AI flavor calibration. The most visually striking screen on any disposable. Slightly larger battery (820 vs 800mAh).

Where the RAZ LTX wins: Independent airflow control (you can run tight MTL in Boost Mode — impossible on the Pulse X). Dark mode for discrete use. Wattage readout on the display. Genuine leather grip insets that feel premium and prevent slipping. Dessert flavor profiles (Night Crawler, Georgia Peach) that the Pulse X lineup completely lacks. The 48+ flavor count slightly edges the Pulse X's 46+. The RAZ also shares manufacturing DNA with Geek Bar (both from GeekVape/Shenzhen ecosystem), so the build quality is comparable.

The bottom line at 25K: These are two excellent devices at identical price points. Choose the Pulse X if you want the best screen experience, AI-tuned flavor delivery, and maximum e-liquid capacity. Choose the RAZ LTX if you want independent airflow customization, a discrete dark-mode display, premium materials, and access to dessert/savory flavor profiles. Neither is categorically better — they're optimized for different user priorities. For full brand comparison: RAZ vs Geek Bar.

Real-World Usage: 14 Days With the Pulse X

Battery cycle: At moderate use (~400 puffs/day, 60/40 Regular/Pulse split), I charged every 1.5-2 days. A full charge via USB-C took approximately 55-65 minutes. The 820mAh battery is a tangible improvement over the Pulse's 650mAh, but as noted, the higher wattage (12W/25W vs 10W/20W) and the power-hungry 3D screen partially offset the capacity increase. Don't expect to go 3 days between charges unless you're a very light user.

Actual puff count: My two test units delivered approximately 19,000-21,000 puffs in Regular Mode before juice depletion — roughly 76-84% of the claimed 25,000. In Pulse Mode, I tracked around 11,000-12,500 actual puffs vs the claimed 15,000. These ratios are consistent with the Pulse 15K's ~80% delivery rate and with industry norms. For a moderate vaper, expect 2.5-4 weeks of use in Regular Mode.

Screen battery drain: The 3D curved screen's animations drain battery faster than the original Pulse's flat panel. With the screen active (which is always, during use), I estimated roughly 5-8% of total battery consumption goes to the display. On the RAZ LTX, the dark mode option lets users reduce screen power — an option the Pulse X doesn't offer. If screen battery drain bothers you, keep sessions in Regular Mode where the animations are less intensive.

Coil longevity at 25W: The enhanced dual mesh coil held flavor quality well through approximately 85-90% of the e-liquid capacity. Below ~15% juice, the expected flavor fade set in. Alternating between Regular and Pulse modes — as I recommended in the Pulse 15K review — seemed to extend the high-quality flavor zone by another 3-5% of total capacity.
