The Geek Bar Pulse X specs come down to five headline numbers: 25,000 puffs in Regular Mode, 15,000 puffs in Pulse Mode, an 18.0 mL tank, an 820 mAh battery, and 5% nicotine. Everything else on the Geek Bar Pulse X spec sheet, from the dual-mesh coils to the 3D curved LED screen, supports those numbers.
This guide walks through each spec one at a time, explains what it does in daily use, and points out where a marketing number needs a reality check. For flavors and setup, our full Geek Bar Pulse X Guide picks up where this page stops. Expect plain English, a little dry humor, and a comparison table you can screenshot.
📋 Table of Contents
The Pulse X is an 18.0 mL rechargeable disposable with dual-mesh coils, two puff modes, a 3D curved LED screen, and USB-C charging. The table below puts the full spec sheet in one place.
| Specification | Details |
|---|---|
| Puff Count | Regular Mode: 25,000 | Pulse Mode: 15,000 |
| E-Liquid Capacity | 18.0 mL |
| Heating Element | Dual-Mesh Coils |
| Display Screen | 3D Curved LED Screen |
| Adjustable Airflow | AI Power Adjustment |
| Battery Size | 820 mAh |
| Nicotine Strength | 5% (about 50 mg/mL) |
| Charging Port | USB Type-C |
Two features set this device apart from older disposables. The first is the dual puff rating, which lets you choose between longevity and intensity. The second is the screen paired with smart airflow, which most earlier models skipped entirely.
These figures follow the manufacturer's published sheet. Puff ratings come from standardized testing, so your own results will vary with draw length and habits. We repeat that reminder wherever it matters.
Read the specs as a system, not as a list. A big tank needs a strong battery to heat it, a strong battery needs a modern charging port, and a smart display helps you track all of it. Each spec supports the others, which is why the Pulse X feels more like one designed product than a pile of impressive numbers.
The Pulse X is rated for up to 25,000 puffs in Regular Mode and up to 15,000 puffs in Pulse Mode. Same tank, same coils, two different pacing choices. You pick the trade-off.
A puff rating is an estimate, not a promise. Manufacturers calculate it from a standard puff length and interval, and real users rarely vape like a lab machine. Think of it as a fuel-economy sticker: useful for comparing devices, optimistic for your commute.
Several factors move your real number up or down. Long, slow draws use more e-liquid per puff than quick sips. Frequent use in Pulse Mode drains the tank faster. Even room temperature can change how thick the e-liquid flows through the mesh. Expect a range, not a fixed figure.
Regular Mode is the endurance setting, rated for up to 25,000 puffs. It uses a steadier power output, so the e-liquid stretches further.
Someone taking 200 to 300 puffs a day could expect roughly 12 to 18 weeks from this mode. That is simple division: 25,000 puffs divided by 300 gives about 83 days, and divided by 200 gives about 125 days.
Pulse Mode is the intensity setting, rated for up to 15,000 puffs. It raises power and airflow for a stronger throat hit and denser vapor, which means the tank empties faster.
At the same 200 to 300 puffs a day, 15,000 puffs lasts about 7 to 11 weeks. You get more punch per pull and fewer pulls overall.

The Pulse X holds 18.0 mL of e-liquid. That is a large tank for a disposable, and it is the main reason the puff ratings climb so high.
More e-liquid generally supports more puffs, as long as the coil and battery keep up. A big tank with a weak coil is like a giant water bottle with a tiny straw. The Pulse X pairs its capacity with dual coils to avoid that problem.
Here is a fact that puts the rating in perspective. Spread 18 mL across 25,000 puffs and each puff uses well under one microliter of e-liquid on paper. That is why ratings are best treated as a ceiling under ideal conditions, not a daily guarantee.
Capacity also affects nicotine totals. At 5% strength, which is about 50 mg of nicotine per mL, an 18 mL tank holds roughly 900 mg in total. That number is worth knowing for two reasons. It shows how much nicotine one device contains, and it is a good reminder to store any vape away from children and pets.
Nicotine is an addictive chemical, according to the FDA and the CDC. The device carries the standard warning for a reason, and it is intended for adults aged 21 and over.
The Pulse X uses an 820 mAh rechargeable battery. That size is designed to keep the coils, the screen, and the airflow system running across the full e-liquid supply, as long as you recharge along the way.
Milliamp-hours measure how much charge a battery holds. At a typical lithium-ion nominal voltage of 3.7 V, 820 mAh works out to roughly 3 watt-hours of stored energy. That is a modest figure, but the device sips power in short bursts rather than drawing it continuously.
The screen and the power adjustment system also draw from the same battery. That is the price of a smarter device, and it is why the Pulse X is built to be recharged rather than run flat once.
Real-world runtime depends on your mode, your draw length, and how often you vape. For a deeper look at runtime testing, read our Geek Bar Pulse X battery life review.
One safety note applies to every disposable with a lithium-ion cell. The U.S. Environmental Protection Agency advises against tossing lithium-ion batteries in household trash or curbside recycling, because damaged cells can start fires. Take spent devices to a battery recycling or household hazardous waste drop-off. You can read the EPA guidance on used lithium-ion batteries for details.
The Pulse X heats e-liquid with two mesh coils instead of one. Two coils mean more heating surface, which usually delivers fuller flavor and thicker vapor, especially in the first half of the device's life.
Mesh coils use a flat, perforated sheet instead of a wound wire. The sheet touches more of the e-liquid at once, so heating is more even and hot spots are less common. The result is more consistent flavor from puff to puff.
With two of them working together, the device can vaporize e-liquid faster without cranking up the temperature. That matters in Pulse Mode, where output is higher and the coil has more work to do.
Mesh coils still wear over time. Flavor and vapor can soften slightly as the tank runs low, which is normal for any disposable. If you want the full technical rundown, our page on the Geek Bar Pulse X dual mesh coil covers heating behavior in more detail.
The Pulse X has a 3D curved LED screen on the front of the body. It shows live device information, so you can check status at a glance instead of guessing when to recharge.
The curved glass wraps around the edge of the device, which makes the screen readable from a wider angle than a flat panel. It also gives the Pulse X a cleaner, more modern look than the blinking LED dots on older disposables.
Typical screen readouts include battery level and remaining e-liquid, along with the active mode. A live display is more than decoration. It saves you from the classic disposable mystery of a device that quits with no warning.
The display also earns its keep on the practical side. Seeing a low-battery warning before a long day out beats discovering a dead device on the train. Seeing the e-liquid level helps you plan a replacement instead of vaping the last drops of a fading coil.
Curious how the screen looks and behaves in daily use? Our overview of the Geek Bar Pulse X 3D curved screen shows what each readout means.
The Pulse X charges through a USB Type-C port. Any standard USB-C cable will do, and you can plug in throughout the life of the device rather than only once.
USB-C is an open connector standard maintained by the USB Implementers Forum. Its main perk is that the plug is reversible, so you never have to flip it three times in the dark.
The connector is also becoming the universal choice. The European Union required USB-C as the common charging port for many small electronics sold there starting in December 2024, and phone makers have followed the trend. In practice, you probably already own a cable that fits.
A few habits keep the battery happy:
The Pulse X adjusts airflow automatically through what the brand calls AI Power Adjustment. It reads how you draw and tunes airflow and power to keep the output steady, so there is no dial to twist.
Short, light pulls and long, deep draws need different amounts of air and power. On a fixed-airflow device, one of those styles always feels slightly off. Automatic adjustment aims to keep flavor and vapor consistent across both.
The system works alongside the two modes. Regular Mode keeps output steady for longevity, while Pulse Mode pushes power and airflow higher for a stronger hit.
The benefit is convenience. You inhale, and the device handles the tuning. The trade-off is that you give up manual control, which some experienced vapers prefer to keep.
In short, the puff count sets your timeline, the tank and nicotine strength set the total supply, the coils and airflow shape the experience, and the battery, screen, and USB-C port keep it all running. Here is how the two modes compare on the numbers that matter.
| Feature | Regular Mode | Pulse Mode |
|---|---|---|
| Rated Puffs | Up to 25,000 | Up to 15,000 |
| Focus | Longevity and steady output | Stronger hit and denser vapor |
| E-Liquid Tank | 18.0 mL | 18.0 mL |
| Heating Element | Dual-Mesh Coils | Dual-Mesh Coils |
| Nicotine Strength | 5% | 5% |
| Estimated Duration (200–300 puffs a day) | About 12–18 weeks | About 7–11 weeks |
| Best For | All-day, steady use | Bolder, more intense sessions |
A quick tip for reading any disposable spec sheet: check the units. Milliamp-hours describe battery capacity, milliliters describe liquid volume, and puffs describe a testing estimate. These three numbers measure different things, so a higher number in one row does not automatically mean a better device overall. Compare like with like, and match each figure to how you actually vape.
If you are also weighing the newer model, read our Geek Bar Pulse X vs Pulse X2 Bull comparison before you decide. It lays out where each device wins.
Authenticity is the next spec that matters, even though it never appears on a sheet. Counterfeit disposables circulate widely, and a fake can differ in coil quality, battery safety, and e-liquid content. Our checklist on whether the Geek Bar Pulse X device is authentic shows what to inspect before you buy.
Age and regulation matter too. Federal law sets the minimum age to buy any tobacco or vapor product at 21, under the Tobacco 21 rule that took effect in December 2019. The FDA regulates e-cigarettes as tobacco products and requires marketing authorization for them, so it is smart to review the agency's current e-cigarette information and your state's rules before purchasing. California also lists nicotine under Proposition 65 as a reproductive toxicant, which is why the warning label appears on our site.
Finally, stock varies by region. Use the Geek Bar Pulse X near me locator to find a retailer that carries it, rather than trusting a random listing.
1. How many puffs does the Geek Bar Pulse X have?
The Geek Bar Pulse X is rated for up to 25,000 puffs in Regular Mode and up to 15,000 puffs in Pulse Mode. Both ratings come from the same 18.0 mL tank and dual-mesh coils. Actual puff counts depend on how long and how often you draw, so treat the figures as a ceiling.
2. What is the battery size of the Geek Bar Pulse X?
The Geek Bar Pulse X uses an 820 mAh rechargeable battery that charges through a USB Type-C port. That capacity powers the dual-mesh coils, the 3D curved LED screen, and the AI Power Adjustment system. Recharge it as needed, rather than waiting until the device is completely drained.
3. How strong is the nicotine in the Geek Bar Pulse X?
The Geek Bar Pulse X contains 5% nicotine, which equals about 50 mg per mL of e-liquid. Across the full 18.0 mL tank, that adds up to roughly 900 mg of nicotine. Nicotine is addictive, and the device is intended only for adults aged 21 and over.
4. What is the difference between Regular Mode and Pulse Mode?
Regular Mode is rated for up to 25,000 puffs and focuses on steady output and longer life. Pulse Mode is rated for up to 15,000 puffs and raises power and airflow for a stronger hit with denser vapor. You trade total puffs for intensity, and the tank size stays the same.
5. Does the Geek Bar Pulse X have adjustable airflow?
Yes, but the adjustment is automatic. The Geek Bar Pulse X uses AI Power Adjustment to read your draw and tune airflow and power in real time. There is no manual dial, so you simply inhale and the device keeps flavor and vapor output consistent for you.
The Geek Bar Pulse X packs a large tank, dual-mesh coils, a smart screen, and USB-C charging into one rechargeable body. Read the specs, pick the mode that fits your pace, and buy only from retailers you can verify.
