Geekvape took everything they learned from rebuildable atomizers and advanced mods and packed it into a disposable format. The result is a device that embarrasses basic disposables while questioning whether the "disposable" category even makes sense at this level of technology.
Geek Bar Pulse X Design and Build
The Pulse X 25K is larger than typical disposables, and there's no avoiding that when you're packing 18mL of e-liquid and a 3D display. The ergonomic shape fits comfortably in hand despite the size, with a matte finish that resists fingerprints and provides grip.
The defining feature is the 3D curved LED display wrapped around the device's midsection. This isn't a basic battery indicator. It shows remaining puff count, battery percentage, current mode, and even animated graphics. The curved design allows visibility from multiple angles, useful when the device is in a cupholder or on a desk.
Build quality reflects Geekvape's hardware expertise. No rattling components, no loose buttons, no concerning flex. The mouthpiece is integrated rather than press-fit, eliminating the wobble common on cheaper disposables.
The 3D Display Deep-Dive
The curved OLED screen wraps approximately 180 degrees around the device body. Information displayed includes:
- Remaining puff count - Counts down from maximum capacity
- Battery percentage - Numerical display, not just color bars
- Current mode - Shows Regular or Pulse mode status
- Animated graphics - Visual feedback during use
The display activates when you draw and during charging, then dims to conserve battery. Brightness is adequate for indoor use but can be hard to read in direct sunlight, a limitation of any screen-equipped device.
Does the display drain battery? Marginally. We noticed perhaps 5-10% faster battery consumption compared to screenless disposables at similar puff counts. Given the 820mAh capacity and fast charging, this tradeoff seems worthwhile for the functionality gained.
Performance: Is Geek Bar Pulse X Good?
The Pulse X 25K delivers genuinely impressive performance that justifies its premium positioning. The combination of dual mesh coils, VPU technology, and AI airflow creates a vaping experience noticeably superior to single-coil disposables.
Dual Mesh Coil Technology
Two mesh coil elements fire simultaneously, increasing vapor production and flavor extraction compared to single-coil designs. The mesh heating elements provide even e-liquid vaporization without hot spots that can cause burnt tastes.
The VPU (Vaporization Processing Unit) technology actively monitors and adjusts coil performance. In practical terms, this means consistent flavor from the first puff through the last few milliliters of e-liquid, a notable improvement over disposables that taste great initially but degrade as they empty.
AI-Powered Airflow
The "AI airflow" marketing sounds like buzzwords, but there's real functionality here. Sensors detect your draw strength and style, adjusting airflow resistance automatically. Gentle puffs meet moderate resistance for MTL-style vaping, while stronger draws open up for looser DTL hits.
You can also manually adjust airflow via the side slider if you prefer consistent resistance. The AI system works best for users who vary their draw intensity throughout the day.
Regular vs Pulse Mode
The Pulse X offers two operating modes:
| Mode | Puff Count | Power Output | Best For |
|---|---|---|---|
| Regular | 25,000 | Standard | All-day use, battery conservation |
| Pulse | 15,000 | Enhanced | Stronger hits, more vapor |
Regular mode delivers consistent, moderate vapor suitable for frequent use. Battery life extends further, and e-liquid consumption is optimized.
Pulse mode increases power output significantly, producing denser vapor and stronger throat hit. The tradeoff is accelerated e-liquid and battery consumption, hence the lower puff count rating.
Switching modes is simple: triple-tap the device or use the mode button (depending on firmware version). The display confirms the active mode.
Geek Bar Pulse X Battery Life and Charging
The 820mAh battery handles the demands of dual coils and a full display while still lasting 400-600 puffs between charges. For most users, that's a full day of moderate use before needing a top-up.
USB-C Fast Charging
The USB-C port supports fast charging that reaches 80% capacity in approximately 20 minutes, a significant advantage over older micro-USB disposables that could take hours. A full charge completes in roughly 45 minutes.
| Charge Time | Battery Level |
|---|---|
| 10 minutes | ~40% |
| 20 minutes | ~80% |
| 45 minutes | 100% |
Pass-through charging allows use during charging, though we recommend fully charging when possible for optimal battery health.
Battery Indicator Accuracy
The numerical battery display proves more useful than color-coded LEDs. You know exactly when to charge rather than guessing whether "blue" means 50% or 70%. The display also shows charging progress when connected to power.
Geek Bar Pulse X Flavors
The Pulse X 25K launches with over 45 flavors spanning fruits, menthols, desserts, candies, and tobacco profiles. The dual mesh coils extract flavor effectively, making the Pulse X one of the better-tasting disposables available.
Top Flavor Recommendations

Geek Bar Pulse vs Pulse X: What's the Difference?
Upgrading from the original Pulse? Here's how the models compare:
| Feature | Geek Bar Pulse | Geek Bar Pulse X |
|---|---|---|
| Puff Count | 15,000 / 7,500 | 25,000 / 15,000 |
| E-Liquid | 16mL | 18mL |
| Battery | 650mAh | 820mAh |
| Display | Flat LED | 3D Curved LED |
| Coil Tech | Dual Mesh | Dual Mesh + VPU |
| Airflow | Manual | AI + Manual |
| Price | $14-17 | $16-20 |
The Pulse X represents a meaningful upgrade across every specification. The VPU coil technology and AI airflow are the most noticeable improvements in actual use, while the larger capacity and curved display add convenience and visual appeal.
Geek Bar Pulse X 25K Pros and Cons
Expanded Pros Analysis
3D Curved Display: More than a gimmick. The wrap-around visibility and detailed information (exact puff count, battery percentage) prove genuinely useful. It's the first disposable display that feels necessary rather than novelty.
25,000 Puffs: At typical use rates, that's 2-4 weeks per device. The value proposition improves significantly over 5,000-puff disposables that need weekly replacement.
AI Airflow: Adjusts to your draw style automatically, or override manually. Either way, you get appropriate resistance for your vaping preference.
USB-C Fast Charging: The 20-minute charge to 80% means you're never without your vape for long. No more multi-hour charging sessions.
Dual Mesh + VPU: Consistent flavor quality throughout the device's lifespan addresses the biggest disposable vape complaint.
45+ Flavors: Extensive selection including 0% nicotine options covers virtually every preference.
Expanded Cons Analysis
Larger Size: The 18mL capacity and display require more device. This isn't pocket-discreet like smaller disposables. Plan for bag or purse carry.
Premium Pricing: At $16-20, it costs more than basic disposables. The value per puff is actually competitive, but the upfront cost is higher.
Display Battery Drain: The screen uses power. It's minimal (maybe 5-10% faster battery consumption), but it's there.
Environmental Concerns: A device this sophisticated being disposable creates significant e-waste. The battery, display, and electronics could theoretically be reusable but aren't. Consider refillable systems if environmental impact concerns you.
Who Should Buy the Geek Bar Pulse X?
Ideal for:
- Tech enthusiasts who appreciate the display and AI features
- Heavy vapers who benefit from 25,000 puff capacity
- Flavor seekers who want consistent taste throughout
- Travelers who need long-lasting, self-contained devices
- Former Pulse users ready for an upgrade
Consider alternatives if:
- Budget-conscious - Basic disposables cost significantly less
- Discretion matters - Smaller devices are more pocketable
- Environmental priority - Refillable systems generate less waste
- Light users - The capacity may be excessive for occasional vaping
Final Verdict
The Geek Bar Pulse X 25K delivers on its premium positioning. The 3D curved display, dual mesh coils with VPU technology, and AI airflow system combine to create a disposable vape experience that rivals entry-level refillable devices in everything except the "disposable" part.
Is it worth the premium over basic disposables? For users who vape regularly and value flavor consistency, display information, and modern features, yes. The per-puff cost actually compares favorably to lower-capacity devices while delivering a superior experience.
The environmental question remains: disposable technology this advanced highlights the wastefulness of the format. But within the disposable category, the Pulse X 25K represents the current state of the art.
