The Geek Bar Pulse X 2 takes the same 18mL tank as the original Geek Bar Pulse X 25000 and squeezes out roughly double the puffs, without making the device any bigger. That is not a typo or a marketing rounding trick, it comes down to real engineering changes in how the device manages e-liquid. Here is what actually changed and whether it is worth the upgrade.
Quick clarification before we go further: this is a review of the Geek Bar Pulse X 2, the second generation of the higher-capacity 25,000-puff Pulse X. It is a different device from the Geek Bar Pulse 2, which is the second generation of the original, smaller 15,000-puff Pulse. Double check which one you are shopping for before you order.
What's Actually New: Pulse X 2 vs the Original Pulse X 25000
| Spec | Original Pulse X 25000 | Pulse X 2 |
|---|---|---|
| Regular Mode puffs | Up to 25,000 | Up to 50,000 |
| Pulse Mode puffs | Up to 15,000 | Up to 25,000 |
| E-liquid capacity | 18mL | 18mL (unchanged) |
| Battery | Standard cell | New 4.35V cell, ~22% more runtime |
| Fast charging | Standard USB-C | 80% in ~20 min with 2A charger |
| Internal chip | VPU | Upgraded VPU |
| Wick material | Standard | New non-woven wick |
Every number moved up, and the tank size did not, which is the detail worth paying attention to here.

The Real Trick: How It Gets More Puffs From the Same Tank
Doubling the puff rating without a bigger tank sounds like a spec sheet exaggeration, but Geek Bar's explanation is fairly straightforward. With most disposables, a meaningful amount of e-liquid never actually gets vaporized, it gets stuck in the wick and goes to waste once the device is done. The Pulse X 2 addresses that with an upgraded VPU chip that Geek Bar says boosts puff output by up to 45% through more precise coil power management, paired with a new non-woven wick material that absorbs and delivers e-liquid more efficiently than the wick in the original Pulse X. Less liquid gets stranded in the wick, so more of the 18mL tank actually turns into usable puffs.
Regular Mode vs Pulse Mode
Regular Mode runs cooler and smoother, tuned for balanced flavor and the longest run, now rated for up to 50,000 puffs. Pulse Mode fires the 0.6-ohm dual mesh coil harder for warmer draws, bigger clouds, and a more intense hit, at the cost of pulling more e-liquid and battery per puff, which brings its rating to about 25,000. The gap between the two modes doubled right along with everything else, so the choice between longevity and intensity is now a bigger one than it was on the original Pulse X.
Battery: A New Cell and Real Fast Charging
Alongside the efficiency gains, Geek Bar gave the Pulse X 2 a new 4.35V battery cell that increases total runtime by roughly 22% over the original Pulse X and enables noticeably faster charging. With a compatible 2-amp USB-C charger, the device can reach 80% charge in about 20 minutes, which is close to enough for a full day of use from a short top-up rather than a long wait.
Curved Display and Cascading Light
The 3D curved display carries over from the original Pulse X but gets a refreshed look, showing active mode, battery level, and remaining e-liquid at a glance. Geek Bar paired it with a new cascading light effect that runs down the side of the device during use, a more polished visual update on top of the same recognizable Pulse X silhouette rather than a full redesign.
Flavor Lineup: Standard and Bull Edition
The Pulse X 2 launches with 23 flavors split across two lines. The Standard lineup carries over well-known Geek Bar flavors like Miami Mint, White Peach Raspberry, Sour Fcuking Fab, Blue Razz Ice, and Watermelon Ice, alongside newer additions like Banana Taffy Freeze, Blueberry Jam, Pink and Blue, Sour Straws, and Wild Cherry Slush. The Bull Edition is the new soda-themed lineup exclusive to this device: five fizzy, energy-drink-inspired flavors, Blue Razz Bull, Coco Berry Bull, Peach Bull, Strawberry Bull, and Watermelon Bull, each built around a sweet-tart soda profile rather than a straightforward fruit or menthol taste.

Should You Upgrade From the Original Pulse X 25000?
- Choose the Pulse X 2 if you want roughly double the puffs without stepping up to a bulkier device
- Choose the Pulse X 2 if faster charging and longer battery runtime matter to your daily routine
- Choose the Pulse X 2 if you want to try the soda-themed Bull Edition flavors, which are exclusive to this device
- Stick with the original Pulse X 25000 if its puff range already covers your habits and you do not need the extra capacity
Final Verdict
The Geek Bar Pulse X 2 is a genuine engineering upgrade, not just a bigger number on the box. Squeezing double the puffs out of the same 18mL tank through a more efficient chip and wick is a real improvement, and the faster charging and Bull Edition flavors round out a device that is easy to recommend for anyone who liked the original Pulse X and wants more out of the same footprint.
Frequently Asked Questions
What is different about the Geek Bar Pulse X 2 compared to the original Pulse X 25000?
The Pulse X 2 raises Regular Mode from 25,000 to 50,000 puffs and Pulse Mode from 15,000 to 25,000 puffs, doubling both ratings from the same 18mL tank. It also adds a new battery cell for faster charging and longer runtime, and an updated VPU chip and wick material that use e-liquid more efficiently.
How does the Geek Bar Pulse X 2 get double the puffs from the same size tank?
Geek Bar credits an upgraded VPU chip and a new non-woven wick material. The VPU manages coil power more precisely and the wick absorbs e-liquid more efficiently, which cuts down on the e-liquid that normally gets stuck in the wick and wasted rather than vaporized.
Is the Geek Bar Pulse X 2 the same as the Geek Bar Pulse 2?
No. The Geek Bar Pulse X 2 is the second generation of the higher-capacity Pulse X 25000, rated for up to 50,000 puffs. The Geek Bar Pulse 2 is a separate device, the second generation of the original 15,000-puff Pulse, rated for up to 25,000 puffs. They are different devices despite the similar naming.
How fast does the Geek Bar Pulse X 2 charge?
It uses a new battery cell with USB-C fast charging and is specified to reach 80% charge in about 20 minutes with a compatible 2-amp charger, which is enough for most of a day's use.
