TL;DR: What’s New With The Geek Bar Pulse 2 25K?
- The Geek Bar Pulse 2 25K now does 25,000 puffs in Regular Mode and 15,000 in Pulse Boost Mode
- 800mAh battery is 23% larger than the original Pulse but still small compared to some alternatives
- New VPU chip gives 32% greater puff output and 30% better e-liquid retention versus the original Pulse
- New Dome Full Screen display replaces the flat panel from the OG; it’s brighter, more readable, and raised from the body
- Updated 0.8ohm dual mesh coils, 5% salt nic, adjustable MTL-to-loose-draw airflow, and a Hubba Edition flavour range are the headline additions
If you’re still on the original Geek Bar Pulse 15K, the Pulse 2 is definitely worth the upgrade (and the pricing is aggressive AF too)
Geek Bar has a habit of releasing new Pulse variants before anyone’s finished their current one. The Pulse X landed, then the Pulse X 25K, then the Pulse X 2 at 50K puffs.
Somewhere in the middle of all that, the Pulse 2 25K showed up and it’s a different device to the X line.
This one is a direct successor to the original Geek Bar Pulse 15K with the same form factor DNA, same core concept, but rebuilt with better internals and a screen that actually earns its place on the device.
So where does the Pulse 2 fit, what’s actually new, and is it worth picking up over the OG? Let me break it down.
What Is the Geek Bar Pulse 2 25K?
The Geek Bar Pulse 2 25K is a rechargeable high-capacity disposable vape and the second generation of Geek Bar’s original Pulse line. It’s not the same as the Pulse X series — that’s a separate product branch. The Pulse 2 sits in direct succession to the original Pulse 15K, taking the dual-mode format that made the original popular and rebuilding it with better hardware across the board.
The headline number is 25,000 puffs in Regular Mode, up from 15,000 on the original. Pulse Boost Mode drops that to 15,000 puffs for heavier vapor and more concentrated flavour. Two modes, one physical switch, same concept as the original — just pushed further in every direction.
It runs a 0.8ohm dual mesh coil setup, a 800mAh battery with fast USB-C charging, and introduces Geek Bar’s Dome Full Screen display. Price varies by retailer, but it sits in the $18-22 range in the US market. Flag for editorial verification before publishing.

What’s New in the Pulse 2? The Key Upgrades
The VPU Chip
The original Pulse ran Geek Bar’s first-generation dual-core chip. The Pulse 2 gets an upgraded VPU (Vaping Processing Unit) that Geek Bar claims delivers 32% greater puff output and 30% better e-liquid retention versus the original. That second number is the one that matters. Better retention means less e-liquid is wasted on heat bleed and condensate — which is directly why the puff count can jump from 15K to 25K without a proportional increase in e-liquid volume. It’s the same engineering logic Geek Bar used to double the Pulse X to 50K puffs. More efficient chip, fewer wasted draws.
The Dome Full Screen
The original Geek Bar Pulse had one of the best screens on a disposable when it launched — a flat full-colour LED panel showing battery and juice levels with accurate readings. The Pulse 2 replaces that with the Dome Full Screen, a raised curved display that sits proud of the device body. It’s brighter and offers better visibility at angles. Whether that meaningfully improves your vaping experience is debatable, but it’s a genuine upgrade rather than a cosmetic rebrand.
Faster Charging
The original Pulse charged at a rate that was fine for its time. The Pulse 2 moves to fast USB-C charging, hitting 80% in 15 minutes. For a device you’re carrying for weeks, that’s a real quality-of-life improvement. A short charge during a break is enough to keep it running.
Adjustable Airflow
One of the persistent criticisms of the original Pulse was that airflow was linked to power mode. You couldn’t run Pulse Mode with a tighter draw — the two were tied together. The Pulse 2 gives you a fully adjustable MTL to loose draw switch that works independently of the mode selector. That’s how it should work, and it’s a fix that was overdue.
The Hubba Edition Flavour Range
The Pulse 2 introduces a “Hubba Edition” flavour range alongside standard options — inspired by Hubba Bubba bubblegum-style profiles. Blue Razz Hubba, Grape Hubba, Lemon Hubba, Strawberry Watermelon Hubba, and White Peach Hubba are the Hubba-specific options.
Geek Bar played it safe with the underlying flavors but did chance by launching the intense and delicious flavors of the Hubba Collection before making B-Pop, Meta Moon, Fcuking Fab, Miami Mint and their many stalwarts available – Vaping.
The full flavour list also includes Blue Razz Ice, Fcuking Fab, Miami Mint, Sour Apple Ice, Sour Gush, Sour Strawberry, Watermelon Ice, White Gummy Ice, Raspberry Watermelon, and Juicy Peach Ice.
Fun Fact: The “Hubba Edition” name is a nod to Hubba Bubba bubblegum, the iconic candy brand that launched in 1979. Geek Bar isn’t the first vape company to draw on nostalgia-driven candy profiles — but the Hubba series is one of the more direct brand-adjacent flavour collaborations the category has seen.
Geek Bar Pulse 2 25K vs Original Geek Bar Pulse 15K: Head to Head
Here’s exactly what changed between the two generations:
| Feature | Original Geek Bar Pulse 15K | Geek Bar Pulse 2 25K |
|---|---|---|
| Regular Mode puffs | 15,000 | 25,000 |
| Pulse Mode puffs | 7,500 | 15,000 |
| Battery | 650mAh | 800mAh (+23%) |
| Charging speed | Standard USB-C | Fast USB-C (0-80% in 15 mins) |
| Coil | Dual mesh | 0.8ohm dual mesh |
| VPU chip | First-gen dual-core | Upgraded dual-core (+32% puff output) |
| E-liquid retention | Baseline | +30% vs original |
| Vapor production | Baseline | +23.7% vs original |
| Display | Flat full-screen LED | Dome Full Screen (raised/curved) |
| Airflow | Mode-linked (not independent) | Fully adjustable MTL to loose draw |
| Nicotine | 5% salt nic | 5% salt nic |
| Flavour range | Original Pulse flavours | Original + Hubba Edition |
The original Pulse was legitimately good for its time — the dual-mode concept, the screen, and the flavour quality set it apart when it launched. But the mode-linked airflow was a real constraint, and the battery needed recharging more than it should for a device at this price point. The Pulse 2 fixes both of those things while also improving puff count, vapour output, and charging speed across the board.
If you’re on the OG Pulse and your current device is running low, the Pulse 2 is the natural next step. There’s no significant reason to stay on the 15K version when the Pulse 2 exists at a similar price point.
How Does the Pulse 2 25K Compare to the Pulse X Range?
Worth addressing because it causes genuine confusion. The Pulse X series and the Pulse 2 are not the same product line.
- The Pulse X 25K is Geek Bar’s premium branch: bigger device, 3D curved starry screen, 820mAh battery, and a more powerful coil running at 25W in Pulse Mode. The Pulse X 2 pushes that further to 50,000 puffs via an upgraded VPU and 1000mAh battery.
- The Pulse 2 25K is the mainstream successor to the original Pulse line: refined hardware, better screen, faster charging, but not positioned as a premium flagship. It’s the sensible everyday upgrade, not the showpiece device.
In real terms: if you want the flashiest screen and the highest puff count available, the Pulse X 2 is the one. If you want a clean, capable, no-fuss update to the OG Pulse experience at a lower price, the Pulse 2 25K is the right choice.
For a broader look at what’s worth picking up right now, our vape reviews category covers the full current landscape.
Fun Fact: The original Geek Bar Pulse 15K was one of the first disposable vapes to introduce a physical mode switch combined with a full-colour display showing real-time battery and juice levels. That combination — two power modes with an accurate status screen — became the template that most high-capacity disposables now follow.
Who Is the Geek Bar Pulse 2 25K For?
It’s a strong fit if you:
- Used the original Geek Bar Pulse and want the next version without jumping to the more expensive X line
- Want independent airflow control rather than mode-linked airflow
- Vape moderately to heavily and want something that lasts weeks rather than days
- Want quick charging that fits into a break or a meal rather than an overnight cycle
- Are interested in bubblegum-adjacent flavour profiles alongside the standard fruit and ice range
It’s probably not the right pick if you:
- Want the highest puff count on the market (the Pulse X 2 at 50K is the one for that)
- Prefer a slim, pocket-sized device — dual mesh coil housings add bulk
- Are ready to move to a refillable pod system for long-term cost savings
For anyone considering the step up to a proper refillable setup, our pod vapes category has options at every budget.
Wrapping Up
The Geek Bar Pulse 2 25K is what a second generation should be: a genuine rebuild of the original, not a marginal spec bump with a new number on the box.
- The adjustable airflow alone fixes the single biggest complaint about the OG.
- Add the faster charging, better VPU efficiency, raised display, and 10,000 extra puffs in Regular Mode, and this is an easy recommendation for anyone still carrying the first-gen Pulse.
It’s not the flashiest thing in the Geek Bar lineup — that’s still the Pulse X 2 — but it doesn’t need to be. It does the job, does it well, and costs less to do it.

FAQ
What’s the difference between the Geek Bar Pulse 2 and the Geek Bar Pulse X?
They’re different product lines. The Pulse 2 is the direct successor to the original Geek Bar Pulse 15K — same everyday positioning, upgraded hardware. The Pulse X is a separate premium branch with a more powerful coil, higher wattage in Pulse Mode, a 3D curved starry screen, and a larger battery. The Pulse X 2 pushes to 50,000 puffs. If you want the premium flagship, go X. If you want a clean upgrade to the original Pulse experience at a lower price, the Pulse 2 is the one.
How long does the Geek Bar Pulse 2 25K actually last?
At an average of 200-300 puffs a day, 25,000 puffs puts you in the 83-125 day range on paper. In practice, puff lengths vary — shorter draws in Regular Mode will push you toward the higher end, Pulse Boost Mode use will reduce that significantly. Most users report 3-6 weeks of real-world use before the e-liquid runs out.
Can you adjust the airflow on the Geek Bar Pulse 2 independently of the power mode?
Yes, and this is one of the key improvements over the original Pulse. The Pulse 2 has a fully adjustable airflow switch that runs from MTL (mouth-to-lung, tighter draw) to a loose direct-lung style draw, and it works independently of whichever power mode you’re in. The original Pulse locked airflow to the mode selector, which was a real limitation.
What nicotine strength does the Geek Bar Pulse 2 come in?
The Pulse 2 comes in 5% (50mg/ml) salt nicotine. That’s a standard strength for US disposable market devices and delivers a smooth throat hit compared to freebase nicotine at similar concentrations. Check retailer listings for any zero-nicotine variant availability.
Is the Geek Bar Pulse 2 worth it over the original Pulse 15K?
Yes, if your original Pulse is running out and you’re buying new. The Pulse 2 costs a comparable amount, delivers significantly more puffs, charges faster, fixes the airflow limitation, and produces more vapour. There’s no compelling reason to stay on the 15K version when the Pulse 2 exists at roughly the same price point.
Vaping products contain nicotine, which is an addictive substance. These products are intended for adult use only (18+ or 21+ depending on local laws).
