Geek Bar Pulse X 25K vs Pulse X 2 50K: Which to Pick

Key Takeaways

• Geek Bar rates the Pulse X 25K at 25,000 puffs from 18 mL of e-liquid on an 820mAh battery.
• Geek Bar rates the Pulse X 2 50K at 50,000 puffs from the same 18 mL, on a 1000mAh battery.
• Both carry a dual mesh coil, adjustable airflow, a screen and USB-C charging, so the choice rests on puff rating and battery size.
• Beside them sit the Pulse 15K at 15,000 puffs with 16 mL and 650mAh, and the Pulse 2 25K at 25,000 puffs with 16 mL and 800mAh.
• All four are 5% nicotine disposables.

The Geek Bar Pulse X 25K and the Geek Bar Pulse X 2 50K hold the same 18 mL of e-liquid and share a dual mesh coil, adjustable airflow, a screen and USB-C charging, so they differ in two places: puff rating and battery. Pick the Pulse X 25K if a 25,000-puff rating on an 820mAh battery covers what you need, and pick the Pulse X 2 50K if you want the 50,000-puff rating and the 1000mAh battery that comes with it.

The rest of this page explains what each of those figures means in daily use, where the two devices sit beside the Pulse 15K and the Pulse 2 25K, and how to choose between them without guessing. Every number here is the catalog figure or Geek Bar's own rating; we have not run a timed count of our own.

What Each Term Means

A disposable vape arrives filled and charged, and you use it until the e-liquid runs out. You recharge the battery over USB-C along the way, and the device is finished when the liquid is gone, so the e-liquid sets its life and the battery sets how far you get between charges.

The puff rating is the maker's count of draws under its own test. Geek Bar publishes it, we report it as given, and your own count will land below it if you take long, slow draws.

Capacity, in mL, is how much e-liquid the device holds when it arrives. Battery capacity, in mAh, is how much charge the cell holds, and a larger figure means more draws before the next cable.

A dual mesh coil is a heating element built from two pieces of mesh rather than a single wound wire. Adjustable airflow is a control on the body that changes how tight or open the draw feels, and the screen is the small display Geek Bar fits to every device on this page.

Where They Differ and Where They Match

Puff Rating: 25,000 Against 50,000

Geek Bar rates the Pulse X 25K at 25,000 puffs and the Pulse X 2 50K at 50,000 puffs. Both hold 18 mL, so the gap in rating comes from how each device draws on the same amount of liquid under Geek Bar's test, and we report both figures exactly as the maker gives them.

Treat either rating as a ceiling. A short, light draw gets you closer to it, and a long, deep draw spends liquid faster on either device. If you already know that a 25,000-puff device feels like it runs out early, the 50,000 rating is the one to look at.

Battery: 820mAh Against 1000mAh

The Pulse X 25K carries an 820mAh battery and the Pulse X 2 50K carries 1000mAh. The larger cell goes longer between charges, which matters on a device rated for 50,000 puffs, because you will be plugging it in many times across its life.

Both charge over USB-C, the same port on most phones, so one cable covers either device. Plan on topping up as you go with both; the battery figure tells you how often, and the screen tells you when.

Coil, Airflow, Screen and Charging Are the Same

Everything else on the spec sheet matches. Both devices run a dual mesh coil, both have adjustable airflow, both carry a screen, and both charge over USB-C, so none of those features will separate the two for you.

Flavor lines do differ between the two families, and each product page carries the current list for that device. If a particular flavor is the reason you are here, check it there before you decide on rating and battery.

Where They Sit Next to the Pulse 15K and Pulse 2 25K

Geek Bar's Pulse line runs from the Pulse 15K up to the Pulse X 2 50K, and we list all four under Geek Bar. Their catalog figures sit side by side here.

The Pulse 15K is the smallest of the four on every figure: 15,000 puffs, 16 mL and a 650mAh battery. The Pulse 2 25K matches the Pulse X 25K on puff rating, with 16 mL and 800mAh against the Pulse X's 18 mL and 820mAh.

So the Pulse X 25K is the 25,000-puff device with the larger e-liquid capacity, and the Pulse 2 25K is the one with the smaller e-liquid capacity at the same rating. The Pulse X 2 50K stands at the top of the four we list on both puff rating and battery, and it is the only one rated past 25,000.

Which One for You

Pick the Pulse X 25K if 25,000 puffs is the range you already know, you want the 18 mL of e-liquid, and an 820mAh battery is fine because you charge often anyway.

Pick the Pulse X 2 50K if you get through a 25,000-puff device faster than you would like, you want the 1000mAh battery, and the longer rated life is worth the larger device in your pocket.

Pick the Pulse 15K if you want the smallest Geek Bar device by rating, and the Pulse 2 25K if you want the 25,000 rating with 16 mL of e-liquid. All four sit in our disposables range at 5% nicotine, so strength is not part of the decision.
