Overview
The Geek Bar Pulse X 25K pushes disposable vape technology about as far as it can go. You get a 3D curved LED display (a first for disposables), dual mesh coils with VPU technology, and AI-powered airflow. This thing is way more than your typical disposable. It shows just how far the category has come.

Geekvape took everything they learned from rebuildable atomizers and advanced mods and crammed it into a disposable format. The result? A device that makes basic disposables look primitive. At this level of tech, you have to wonder if "disposable" is even the right word anymore.
Geek Bar Pulse X Design and Build
The Pulse X 25K is bigger than typical disposables. No getting around that when you're packing 18mL of e-liquid and a 3D display. The shape fits comfortably in hand despite the size, and the matte finish resists fingerprints while giving you a solid grip.
The standout feature is the 3D curved LED display wrapped around the device's midsection. This isn't just a battery indicator. It shows remaining puff count, battery percentage, current mode, and animated graphics. The curved design lets you see it from multiple angles, which is handy when the device is sitting in a cupholder or on your desk.
Build quality reflects Geekvape's hardware expertise. No rattling components, no loose buttons, no flex when you squeeze it. The mouthpiece is integrated rather than press-fit, so there's none of that wobble you get on cheaper disposables.
The 3D Display Deep-Dive
The curved OLED screen wraps about 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 fine indoors but can be hard to read in direct sunlight. That's true of any screen-equipped device though.
Does the display drain battery? A little. We noticed maybe 5-10% faster battery consumption compared to screenless disposables at similar puff counts. Given the 820mAh capacity and fast charging, that tradeoff is worth it for what you get.
Performance: Is Geek Bar Pulse X Good?
The Pulse X 25K performs well above its weight class. The combination of dual mesh coils, VPU technology, and AI airflow creates a vaping experience that single-coil disposables just can't match.
Dual Mesh Coil Technology
Two mesh coil elements fire at the same time, boosting vapor production and flavor extraction over single-coil designs. The mesh heating elements vaporize e-liquid evenly without hot spots that can cause burnt tastes.
The VPU (Vaporization Processing Unit) technology monitors and adjusts coil performance on the fly. What this actually means: consistent flavor from your first puff to the last few milliliters of e-liquid. Most disposables taste great at first but degrade as they empty. The Pulse X doesn't have that problem.
AI-Powered Airflow
"AI airflow" sounds like marketing speak, but there's real functionality here. Sensors detect your draw strength and style, adjusting airflow resistance automatically. Gentle puffs get moderate resistance for MTL-style vaping. Stronger draws open up for looser DTL hits.
You can also manually adjust airflow with the side slider if you prefer consistent resistance. The AI system works best for people 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 for everyday use. Battery lasts longer and e-liquid consumption stays efficient.
Pulse mode cranks up the power, producing denser vapor and stronger throat hit. The tradeoff is faster e-liquid and battery drain, which is why it's rated for fewer puffs.
Switching modes is easy. Triple-tap the device or use the mode button (depends on firmware version). The display confirms which mode you're in.
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 people, that's a full day of moderate use before you need to plug it in.
USB-C Fast Charging
The USB-C port supports fast charging that hits 80% in about 20 minutes. That's a big step up from older micro-USB disposables that could take hours. A full charge takes about 45 minutes.
| Charge Time | Battery Level |
|---|---|
| 10 minutes | ~40% |
| 20 minutes | ~80% |
| 45 minutes | 100% |
Pass-through charging lets you vape while charging, though we recommend charging fully when you can for better battery health.
Battery Indicator Accuracy
The numerical battery display is way more useful than color-coded LEDs. You know exactly when to charge instead of guessing whether "blue" means 50% or 70%. The display also shows charging progress when you plug it in.
Geek Bar Pulse X Flavors
The Pulse X 25K comes in over 45 flavors across fruits, menthols, desserts, candies, and tobacco profiles. The dual mesh coils extract flavor well, making the Pulse X one of the better-tasting disposables out there.

|---|---|---|
| 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 is a real upgrade across every spec. The VPU coil technology and AI airflow are the biggest differences you'll actually feel when using it. The larger capacity and curved display are nice bonuses.
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) are actually useful. It's the first disposable display that feels necessary rather than just flashy.
25,000 Puffs: At typical use rates, that's 2-4 weeks per device. Much better value than 5,000-puff disposables that need weekly replacement.
AI Airflow: Adjusts to your draw style automatically, or you can override it manually. Either way, you get the resistance you want.
USB-C Fast Charging: Getting to 80% in 20 minutes means you're never without your vape for long. No more multi-hour charging sessions.
Dual Mesh + VPU: Consistent flavor throughout the device's lifespan solves the biggest disposable vape complaint.
45+ Flavors: Big selection including 0% nicotine options covers pretty much every preference.
Expanded Cons Analysis
Larger Size: The 18mL capacity and display require more device. This isn't pocket-discreet like smaller disposables. You'll want to carry it in a bag or purse.
Premium Pricing: At $16-20, it costs more than basic disposables. The value per puff is 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 a lot of e-waste. The battery, display, and electronics could theoretically be reusable but aren't. Consider refillable systems if you care about environmental impact.
Who Should Buy the Geek Bar Pulse X?
Ideal for:
- Tech enthusiasts who like the display and AI features
- Heavy vapers who'll actually use that 25,000 puff capacity
- Flavor seekers who want consistent taste from start to finish
- Travelers who need a long-lasting, self-contained device
- Former Pulse users looking for an upgrade
Consider alternatives if:
- Budget-conscious - Basic disposables cost way less
- Discretion matters - Smaller devices fit in pockets better
- Environmental priority - Refillable systems create less waste
- Light users - This much capacity is overkill 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 an experience that rivals entry-level refillable devices. The only difference is you throw this one away.
Is it worth the premium over basic disposables? If you vape regularly and care about flavor consistency, useful display info, and modern features, yes. The per-puff cost compares favorably to lower-capacity devices, and the experience is better.
The environmental question still lingers. Disposable technology this advanced really highlights how wasteful the format can be. But if you're staying in the disposable category, the Pulse X 25K is the best option available right now.
