The original Geek Bar Pulse X has been one of the best sellers in our shop since it landed. It has a big tank, a screen that tells you what is left, and a Pulse Mode that gives you a bigger hit when you want one. It earned its spot.

Now the Pulse X 2 is here, and the question we keep hearing at the counter is simple. Should I switch? Some customers grab the new one the moment they see it. Others are happy with what they have and don’t want to pay for features they won’t use.

Big Mo’s carries both, so we have no reason to push you one way or the other. Here is a straight, side-by-side look at what changed, what stayed the same, and who actually benefits from the upgrade.

TLDR:

The Geek Bar Pulse X 2 doubles the rated puff count: up to 50,000 in Regular Mode and 25,000 in Pulse Mode, compared to 25,000 and 15,000 on the original.
Both hold 18mL of 5% nicotine salt e-liquid, so the bigger puff rating comes from a more efficient coil and chip, not a bigger tank.
The Pulse X 2 has a larger 1000mAh battery (up from 820mAh), faster USB-C charging, and adjustable airflow.
It is slightly bigger and heavier than the original.
Upgrade if you use Pulse Mode a lot, want control over your draw, or hate charging. Stick with the original if you are happy with it and want to save a few dollars.

What Actually Changed

Double the Puff Rating From the Same Tank

This is the headline. The Pulse X 2 is rated for up to 50,000 puffs in Regular Mode, twice the original. What surprises most people is that the tank size did not change. Both devices hold 18mL.

So where do the extra puffs come from? The Pulse X 2 uses a 0.6 ohm dual mesh coil paired with a VPU chip that manages how much vapor each puff produces. In plain terms, it uses the liquid more efficiently. Keep in mind that puff ratings are lab numbers. Long draws and chain vaping will bring your real-world count down on either device.

A Bigger Battery and Faster Charging

The battery went from 820mAh to 1000mAh. Charging is faster too. A quick 20-minute charge gets you to around 80%, which is handy if you forgot to plug it in overnight.

You will still need to charge it. With mixed use, most people get around three days per charge. Running Pulse Mode all day drains it faster.

Adjustable Airflow

The original Pulse X had a fixed draw. The Pulse X 2 adds adjustable airflow, which is a first for the Pulse line. You can keep it tight for a cigarette-style pull or open it up a bit for a looser, airier draw. For people who found the original too restrictive, this alone might be worth the upgrade.

Display and Light Ring

Both devices show battery and e-liquid levels on a curved screen. The Pulse X 2 adds a Halo light ring and a starry display pattern that wraps around the body. It looks sharp. It is also flashy, so if you prefer something low-key, that is worth knowing.

What Stayed the Same

A lot of what made the original Pulse X good carries over. Both use draw activation with no buttons to press. Both have Regular Mode and Pulse Mode. And both use 5% nicotine salt, so the hit strength feels familiar.

The overall shape is close, too. If you liked how the original felt in your hand, the Pulse X 2 will not feel strange. It is just a bit bulkier.

Regular Mode vs. Pulse Mode on Each Device

Pulse Mode is where the gap between the two devices is most noticeable. On the original Pulse X, Pulse Mode cut your rated puffs from 25,000 to 15,000. On the Pulse X 2, Pulse Mode is rated for 25,000 puffs, the same as Regular Mode on the original.

Mode	Pulse X	Pulse X 2	What You’ll Notice
Regular Mode	Up to 25,000 puffs	Up to 50,000 puffs	Smooth, steady flavor and longer device life
Pulse Mode	Up to 15,000 puffs	Up to 25,000 puffs	Denser vapor, stronger flavor, faster battery drain

If you live in Pulse Mode, the Pulse X 2 gives you a lot more device for your money.

Flavors

The Pulse X 2 launched with the Bull Edition flavors, a set of energy-drink inspired blends like Blue Razz Bull, Strawberry Bull and Peach Bull. More flavors have rolled out since. The original Pulse X has a deep flavor catalog of its own, and many of the classic fan favorites are still easiest to find in that version.

If you have a specific flavor you love on the original, check whether it is available in the Pulse X 2 before switching.
