Two of the most-searched disposable vapes in the US right now sit right next to each other on shelves. Same brand. Similar name. Different device. Here's the actual breakdown.
The Specs
The Geek Bar Pulse 15K holds 16mL of e-liquid and delivers up to 15,000 puffs in normal mode. The Pulse X 25K bumps that to 18mL and 25,000 puffs — plus adjustable airflow and a 3D curved screen. Both run on USB-C charging. Both come in 5% nicotine salt.
The battery gap matters more than people realize. The Pulse runs a 650mAh cell. The Pulse X runs 820mAh — and fast-charges to 70% in just 15 minutes via a 9V/2A USB-C handshake. If you've ever watched a disposable die mid-session, that's the upgrade worth paying for.
Two Modes, One Key Difference
Both devices toggle between Regular mode and Pulse mode. Regular gives you a higher puff count and a cooler draw. Pulse mode pushes more power for bigger clouds and stronger flavor — but burns through juice faster.
The Pulse X improved on this specifically. It toggles between 12-watt draws in regular mode and 20-watt bursts in Pulse mode. The original Pulse doesn't publish wattage figures the same way, and real-world users report flavor drop-off as the battery drains. The X addresses that directly with better coil consistency at lower voltage.
Airflow
This is where the two devices actually split. The original Pulse has fixed airflow — no adjustment, no options. The Pulse X has a one-click adjustable airflow switch. Tighten it for a tighter, more intense draw. Open it for a looser, cloudier hit. On most disposables, airflow controls are barely worth mentioning. On the Pulse X, it's one of the better implementations in the category.
The Screen
The Pulse X was the first disposable to ship with a 3D curved LED screen. It shows puff count, battery percentage, and current mode in real time. The original Pulse has a flat LED screen showing the same basic info. Both are useful. The X is noticeably sharper.
Flavors
Both lines cover the classics — Blue Razz Ice, Watermelon Ice, Sour Apple Ice, Cool Mint. The Pulse X has expanded into special editions: the Thermal Edition, Meteor Edition, Slush Edition, and Platinum Edition, each with exclusive flavor profiles. Geek Bar dropped 13 fresh Pulse X flavors in April 2025 alone. More than 30 active SKUs are currently in circulation across both lines.
Price and Value
Most online vape shops list the Geek Bar Pulse anywhere from $18 to $22 per unit, and the Pulse X between $22 and $28. Those prices add up fast if you're going through one a week.
At Vaper Dudes, you're not paying retail markup. The Geek Bar Pulse is currently on sale for $15.99 — down from the regular $30 retail price. The Pulse X starts at $17.99, marked down from $35. That's a significant gap from what most other sites are charging, and both are in stock now.
The cost-per-puff math already favors the Pulse X for daily vapers — 25,000 puffs for just a couple dollars more than the Pulse. At Vaper Dudes' prices, that gap shrinks even further, making the Pulse X the obvious long-term value pick. But if you want to try the Pulse first without spending much, $15.99 is about as low as you'll find it anywhere online.
Either way, skip the markup. Shop both devices at Vaper Dudes and get the same authentic Geek Bar product at a price that actually makes sense.
So Which One?
Buy the Geek Bar Pulse if you vape occasionally, like rotating through flavors often, or just want a reliable, lower-cost option. It still delivers 15,000 puffs of consistent flavor with a real display and USB-C charging. Nothing basic about it.
Buy the Geek Bar Pulse X if you vape every day, want control over your draw, hate running out mid-day, or want maximum value per dollar over time. The fast charging alone is worth it for daily users.
Same core experience. The X just does more of it, better.
Must be 21+ to purchase vaping products. This product contains nicotine, which is an addictive chemical.
