Geek Bar Pulse X 2 Review: 50,000 Puffs, Galaxy Cascade UI, and Dual Mode Power

The Geek Bar Pulse X 2 is the next-generation successor to the Pulse X 25K, and it doubles nearly everything that mattered about the original. Regular Mode now reaches 50,000 puffs, the battery jumps to 1000mAh, and the screen has been completely redesigned with the new Galaxy Cascade UI animation, refined Stardot Screen Film, and integrated Binary Halo Light strips. This review covers every spec, both editions, all 15 flavors, and what changed vs the Pulse X 25K. The full lineup is in stock at the Geek Bar Pulse X 2 collection at JellyPuffs.

What Is the Geek Bar Pulse X 2?

The Geek Bar Pulse X 2 is the latest iteration in Geek Bar’s flagship Pulse series, released as the direct successor to the Pulse X 25K. The headline change is puff capacity. Regular Mode now reaches up to 50,000 puffs, and Pulse Mode delivers up to 25,000 puffs — effectively doubling the original Pulse X numbers from a tank that holds the same 18mL of e-liquid.

The chassis keeps the wide, box-shaped form factor that defined the Pulse X but adds a redesigned 3D curved screen with a new Galaxy Cascade UI animation, a refined Stardot Screen Film overlay for crisper visuals, and integrated Binary Halo Light strips that frame the display along the top and bottom edges. Internally, the upgrade comes from a new VPU dual-core chipset and a battery boosted from the 820mAh of the original Pulse X to a full 1000mAh.

The lineup ships in two distinct editions. The Bull Edition covers 5 flavors that layer fruit profiles over a charged blue-can energy-drink base, marked by a bull-horns logo on the device. The Standard Edition covers 10 flavors across traditional disposable vape categories — fruit-and-ice, sour candy, dessert, and pure mint — without the energy-drink crossover.

Full Device Specs

Here are the confirmed specs for the Geek Bar Pulse X 2:

What’s New vs the Pulse X 25K

The Pulse X 2 carries forward the same form factor, dual mesh coil architecture, 18mL tank, and 5% nicotine strength as the original Pulse X 25K. Four areas changed meaningfully:

The headline number is the doubled puff count from the same 18mL tank. The upgraded VPU chipset is the engineering reason that math works — Geek Bar quotes a 38% improvement in e-liquid retention efficiency, meaning each puff converts more of the e-liquid to vapor and less is wasted on coil heat or vented as condensate. The 18mL tank was already among the larger capacities in the disposable vape category, and pairing it with a more efficient chipset is what unlocks 50K puffs without enlarging the device.

The screen redesign is the most visible upgrade. The original Pulse X used a 3D curved display with the Starry UI, which was already industry-leading for a disposable. The Pulse X 2 replaces that with the new Galaxy Cascade UI animation, refines the screen treatment with the Stardot Screen Film overlay, and adds the Binary Halo Light LED strips that frame the display top and bottom. Together these make the Pulse X 2 screen significantly more interactive than the original.

The battery upgrade is more practical than dramatic. Going from 820mAh to 1000mAh is a 22% increase in capacity, which means fewer charge cycles across the device’s longer puff life. With double the puff count and only 22% more battery, charging frequency relative to puff count is actually higher on the Pulse X 2 — but the fast-charging USB-C means each top-up is still a sub-30-minute operation.

Dual Power Modes: Regular vs Pulse

The Pulse X 2 has two power modes selected via a slider switch on the base of the device. The on-screen Galaxy Cascade UI animation visually shifts between the two modes so the active setting is always visible at a glance.

The two modes are not strictly better or worse than each other — they prioritize different things. Regular Mode is the all-day default that maximizes how long the device lasts. Pulse Mode is for sessions where you want the flavor turned up and don’t mind burning through the device faster. The slider on the base lets you flip between them at any time, and the on-screen animation gives you instant feedback that the change registered.

One practical note: most buyers settle into Regular Mode for the bulk of the device’s life and switch to Pulse Mode for specific flavors or moments where the extra intensity matters. Iced flavors like Watermelon Ice and Blue Razz Ice show the menthol pop more clearly in Pulse Mode, while sweet candy profiles like the Bull Edition flavors stay easier-drinking in Regular.

The 3D Curved Screen and Galaxy Cascade UI

The most visible upgrade on the Pulse X 2 is the screen. Geek Bar refined the display with three named visual layers that together make this one of the most interactive disposable displays on the market.

Stardot Screen Film is a fine star-pattern overlay applied to the screen surface itself. It serves two purposes: it makes the icon rendering crisper at small sizes, and it gives the device a textured premium look even when the display is off. From a user perspective, you mostly notice the result rather than the film — icons feel sharper and the display reads more clearly at an angle.

Galaxy Cascade UI is the new animated interface that runs across the screen during active use. In Regular Mode, the animation is a meteor-cascade visual — small streaks fall across the display in cool tones. In Pulse Mode, the animation shifts to a glowing planet display with a halo, signaling the higher wattage and denser vapor. Battery percentage, e-liquid level, current mode, and puff count are all visible alongside the animation without any button presses.

Binary Halo Light is the integrated LED strip running along the top and bottom edges of the screen panel. The light changes color to match the active mode — cooler tones in Regular, warmer in Pulse — and serves as a secondary visual cue that supplements the on-screen mode indicator. The halo lights also give the device a recognizable silhouette in low light.

For a disposable vape, the screen is intentionally over-the-top. If you want a discreet device, this isn’t it — the animations are bright, the halo lights glow visibly, and the wraparound curve means parts of the display are visible from multiple angles. If you want the screen to be part of the experience and the visual feedback to be useful, the Pulse X 2 delivers more than any disposable on the market right now.

The wraparound 3D curved profile is shared with the original Pulse X, but the visual layers above are all new for the Pulse X 2.

Battery, Coil, and the VPU Chipset

The Pulse X 2 carries a 1000mAh internal battery, up from the 820mAh in the original Pulse X. USB Type-C fast charging brings the device from 0 to 80% in roughly 20 minutes — fast enough that a single coffee break is enough to top up between sessions. The cable is not included in the box, but any standard USB-C cable will work.

The dual mesh coil carries forward unchanged from the Pulse X. Two mesh heating elements run in parallel, distributing heat across a wider surface area than a single-coil disposable. This is what keeps flavor consistent late in the device’s life and what allows Pulse Mode to generate denser vapor when both coils are pushed harder. Mesh coils have become standard at the high end of the disposable category specifically because of how much more even the vapor production is compared to traditional wire coils.

The new VPU dual-core chipset is the engineering story behind the doubled puff count. Geek Bar quotes a 38% improvement in e-liquid retention efficiency over the previous chipset — the same 18mL tank delivers twice the puffs in Regular Mode because the chipset wastes less e-liquid per draw and manages power delivery more dynamically. In practical terms, this shows up two ways: total puff count is much higher, and the last 20% of the device’s life doesn’t fade in vapor density the way unmanaged disposables tend to.

The chipset also handles the mode-switching logic, the on-screen animations, and the puff counter. The puff count displayed on the screen is calculated from actual vapor output, not just timed activations, which is why the published numbers are reliable for comparison purposes.

The Two Editions: Bull vs Standard

The Pulse X 2 ships in two distinct editions with different flavor positioning. The hardware is identical between them — same battery, screen, coil, modes, and airflow. The only differences are the flavor lineup and the chassis branding.

The Bull Edition covers 5 flavors that layer fruit profiles over a charged blue-can energy-drink base. Each flavor reads as fruit + energy-drink fizz, and the device is marked with the bull-horns logo on the chassis. This is the lineup for buyers who want the energy-drink crossover experience — if you’ve enjoyed Red Bull-themed candy or energy-drink-flavored beverages, this edition extends that into vape form. None of the Bull Edition flavors carry menthol or ice.

The Standard Edition covers 10 flavors across traditional disposable vape categories without the energy-drink layer. The breakdown is:

• 5 non-iced flavors: White Peach Raspberry, Pink & Blue, Sour Straws, Sour Fcuking Fab, Blueberry Jam
• 3 full-menthol flavors: Watermelon Ice, Miami Mint, Blue Razz Ice
• 2 light-cooling flavors: Wild Cherry Slush (slushie-style chill), Banana Taffy Freeze (light freeze)

If you’re choosing between editions, the question is whether you want the energy-drink crossover or not. The Standard Edition covers a wider range of flavor categories — mint, sour candy, dessert, and ice fruit are all represented. The Bull Edition is more focused but distinct in a way nothing else in the disposable category is.

Real-World Performance Notes

A few notes on day-to-day use that don’t show up cleanly in a spec sheet:

Heat management. The device runs cool even in Pulse Mode thanks to the dual mesh coil distribution and the VPU chipset’s dynamic power management. Extended Pulse Mode sessions warm the device noticeably but never uncomfortably.

Draw resistance. The adjustable airflow tunes from a tight cigarette-style MTL inhale on the most restricted setting to a looser DTL pull on the most open. Most buyers will land somewhere in the middle — tight enough to taste the flavor concentrated, loose enough to pull comfortable volume on each draw.

Display battery cost. The screen is on whenever the device is in active use, and the Galaxy Cascade animation runs continuously during draws. This is built into the rated puff counts — you won’t get more puffs by somehow turning the screen off, and there’s no setting to disable it.

Pocket profile. At the wider box-mod form factor, this is not a slim-pocket device. It fits in jacket pockets, bags, and large pant pockets comfortably. Tight jeans pockets are not realistic for daily carry. The width is the trade-off for the screen and the 18mL tank.

First-puff consistency. No priming needed out of the box. Draw activation triggers immediately and the dual mesh coil produces full-density vapor from the very first inhale.

Late-life flavor. The VPU chipset’s main user-visible benefit is flavor consistency past the 70% e-liquid mark. The Pulse X 2 holds flavor closer to the end of the device’s life than the original Pulse X did — the last few thousand puffs taste noticeably more like the first few thousand than they would on an unmanaged disposable.

Charging behavior. The 0–80% in 20 minutes is real but the final 20% takes longer (closer to 15–20 additional minutes) as the chipset throttles current to protect the battery. Most users top up to 80% rather than waiting for 100%.
