Geek Bar Pulse X2 50K Review: Specs, Modes, and Flavors

Key Takeaways

• Rated Puffs: Up to 50,000 puffs in Regular mode and about 25,000 in Pulse mode, which doubles the Pulse X 25K's Regular-mode rating.
• Hardware: 18 mL of 5% (50 mg/mL) nicotine salt e-liquid, a 1,000mAh battery, and a 0.6Ω dual mesh coil managed by Geek Bar's vape processing unit (VPU) chip.
• Battery Life: Expect about three to four days per charge with mostly Regular-mode use, and two days or less if you stay in Pulse mode.
• Charging: USB-C gets you to roughly 80% in 20 minutes.
• Best Fit: Experienced vapers and adult smokers switching over who want a long-lasting disposable with a stronger setting on tap.
• Trade-Offs: It's big at 110 g, the light show isn't subtle, and your real puff count depends on how you vape.

The Geek Bar Pulse X 2 50K launched in May 2026 as the next step up from the Pulse X 25K, boasting a headline-grabbing 50,000-puff rating in Regular mode, which is double its predecessor without adding extra e-liquid. That bold claim got our attention and invites a closer look. This review breaks down what changed inside, how the dual modes perform, which flavors stand out, and whether the 50,000-puff mark is realistic. 

We stock the Pulse X 2 at PerfectVape, so we want it to sell, but we care more about matching you with the right device. Because of that, we give the trade-offs just as much spotlight as the advertised upgrades. 

What Is the Geek Bar Pulse X 2 50K?

Geek Bar styles the name "Pulse X 2," and it's a rechargeable, prefilled disposable with two power settings. Regular mode is the efficient everyday setting. Pulse mode, on the other hand, pushes more power through the coils for warmer, denser vapor. A 3D curved screen shows your battery and e-liquid levels at a glance.

Full Specs at a Glance

Here's the full spec sheet, pulled from Geek Bar's product page and our own listing, with size and weight from Versed Vaper's hands-on review.

Who It's Built For

Experienced vapers and adult smokers making the switch are the target here. Every Pulse X 2 ships at 5% (50 mg/mL), and there's no lower-strength version. Pulse mode makes that strength hit even harder, so if you're new to vaping or usually stick to 3% or less, start with something gentler.

Design and Display

Size and Feel in the Hand

At 110 g and close to 95 mm tall, the Pulse X 2 sits closer to a small pod mod than a slim stick. It fills your palm, and a tight jeans pocket won't love it.

The rounded edges and the grippy body help a lot during long sessions, though. Versed Vaper used one daily for two weeks and called the build quality refined and comfortable to hold.

Curved Screen and Halo Lights

Most of the visual upgrades on the Pulse X are right on its surface. Geek Bar added a clear top layer over the curved display, along with Binary Halo light strips that glow green in Regular mode and orange in Pulse mode, so you can tell which setting you're in from across the room.

The animated "Galaxy Cascade" interface looks slick. It's also a lot, and if you want something low-key for the office, the light show may bug you. What makes the screen worth having is the e-liquid gauge. Screenless disposables can die with juice still inside or run dry with charge left over, and the Pulse X 2 shows both levels so neither one surprises you.

Regular Mode vs. Pulse Mode

The mode setting defines this device's personality, and you can swap between the two anytime.

How Each Mode Feels

Regular mode runs at lower power. Draws feel smoother and a little cooler, while flavor stays balanced. Both the battery and the e-liquid stretch as far as they'll go. Geek Bar bases its 50,000-puff rating on this mode alone, according to its in-house GEEKLAB testing.

Flip to Pulse, and both mesh coils fire harder. You get thicker, warmer vapor and a bolder flavor. The throat hit gets noticeably stronger, too, with 5% nicotine behind it. In this mode, you give up longevity, since Pulse mode is rated for about 25,000 puffs, half the Regular figure.

One note on airflow: spec sheets list it as adjustable, but Versed Vaper's tester found the draw is mostly set by the mode itself, with a tight mouth-to-lung (MTL) pull in Regular mode and a slightly looser MTL pull in Pulse mode. So, if a wide-open draw is what you want, look elsewhere.

Which Mode Should You Use?

Choosing a mode depends on what you need for a given session. This cheat sheet covers the most common situations.

Our take is to live in Regular mode and treat Pulse as a once-or-twice-a-day boost. You'll get the stronger hit when you want it without burning through the device in a week.

Flavor Performance

PerfectVape carries 28 Pulse X 2 flavors, split between the standard lineup and the energy-drink-style Bull Edition. Both editions use identical hardware, so what's in the tank (and the shell design) is the only difference.

Bull Edition Flavors

The Bull Edition includes five flavors that pair a fruit with a tart, lightly fizzy energy-drink base, and none of them are iced.

Standard Edition Standouts

The standard lineup covers familiar ground. Watermelon Ice and Blue Razz Ice lead the iced options, with Miami Mint for straight mint fans.

Slush flavors like Wild Cherry Slush, Grape Slush, Peach Slush, and Banana Taffy Freeze bring a lighter chill to fruit, whereas White Peach Raspberry, Sour Straws, Blueberry Jam, and Pink & Blue skip the ice entirely. Hands-on testing turned up one surprise: Blueberry Jam tastes more like fresh raspberry than blueberry. Watermelon Ice came across as natural, with only a mild chill.

Flavor Consistency Over the Device's Life

Big disposables often taste muted by the last third of the tank, and Geek Bar's dual mesh coils and VPU chip are meant to fix that. The company says the VPU improves e-liquid reflow and retention, and it pairs that with finer wicking fibers for more even saturation. Testers report flavor and draw holding steady until the battery runs out.

However, there is a catch to this otherwise great advancement: if a device tastes the same at 5% battery as it did at 100%, it gives you no warning before it quits. This makes tracking your battery gauge more important than ever.

Battery Life and Charging

The Geek Bar's upgraded 1,000mAh battery delivers reliable multi-day performance and quick USB-C charging tailored to your vaping style.

1,000mAh Battery in Daily Use

Geek Bar bumped the battery to 1,000mAh, up about 22% from the 820mAh cell in the Pulse X. Here's how long one charge lasted over two weeks of Versed Vaper testing.

Your numbers will shift with how long and how often you pull. The general pattern holds, though, with Pulse mode roughly halving your time between charges.

USB-C Charging Speed

Charging is quick. A USB-C cable gets you to about 80% in 20 minutes, and a full charge takes around 40 minutes. That last stretch slows down by design to protect the battery, so stopping at 80% makes sense on a busy day.

The U.S. Food and Drug Administration (FDA) publishes battery safety tips worth following for any rechargeable vape. Charge with a quality cable and don't leave the device charging overnight or unattended. Heat matters too, so keep it out of hot cars.

Is 50,000 Puffs Realistic?

How Puff Counts Are Rated

Geek Bar says the 50,000 figure comes from GEEKLAB internal testing in Regular mode only. No shared industry standard measures puffs, so every brand's number is a best-case lab result. People take longer, deeper drags than a test rig does, and that's where the gap opens up.

The E-Liquid Math

You can sanity-check any puff rating with simple math. The Pulse X 2 holds 18 mL of e-liquid. Propylene glycol weighs about 1.04 g/mL and vegetable glycerin about 1.26 g/mL, so a typical blend puts 18 mL at about 20 g, or 20,000 mg.

Spread that over 50,000 puffs, and each one uses about 0.4 mg of liquid. For comparison, a 2013 study of experienced vapers on early devices measured roughly 62 mg of liquid used over 13 puffs, close to 5 mg per puff. While today's low-power MTL disposables use far less per puff than those old tank setups did, the gap shows how light a puff has to be to reach 50K.

The Pulse X 2 is still a solid buy despite the optimistic rating. It holds the same 18 mL as other high-capacity disposables like the Lost Mary MT35000 Turbo and gets more mileage than the Pulse X. Just plan on your real count landing under 50,000 if you take long drags or lean on Pulse mode.

Geek Bar Pulse X vs. Pulse X 2

The Pulse X 25K is still on shelves, so it's fair to ask what the extra money and size get you.

What Changed Inside

The tank size didn't move. The gains come from the bigger battery and the upgraded VPU, which Geek Bar says handles power and e-liquid flow more efficiently. In practice, you get more mileage from the same 18 mL and stronger hardware behind Pulse mode.

Is the Upgrade Worth It?

If your Pulse X 25K works fine and you rarely touch Pulse mode, the jump isn't urgent. Heavy vapers and anyone who likes the stronger setting will notice the bigger battery and better efficiency right away, mostly in the form of fewer device swaps each month.

How the Pulse X 2 Compares to Other High-Puff Disposables

Lost Mary chases the same buyer with its own dual-mode devices. Here's how the Pulse X2 lines up against two of them on paper.

Specs Side by Side

Which One Fits You

The VIZ 55K posts the biggest number, while the MT35000 Turbo keeps its rating more modest. The Pulse X 2 lands between them and ties the MT35000 Turbo for the group's largest battery. If screen quality and battery size matter more than the top-line puff figure, we'd grab the Pulse X 2.

Pros and Cons

Here's the short version before you decide.

Tips to Get the Most Out of Your Pulse X 2

A few habits will stretch every device further:

1. Default to Regular mode and switch to Pulse only when you want a stronger hit.
2. Take shorter, gentler draws, since long pulls use more liquid per puff.
3. Charge to 80% when you're short on time, because that's the fast part of the charging curve.
4. Watch the e-liquid gauge as closely as the battery, since the flavor won't fade to warn you.
5. Keep it out of hot cars and away from freezing temperatures. Heat can break down e-liquid, and cold thickens it until the device warms up.
6. Buy from an authorized seller. Counterfeit Geek Bars circulate widely, and you can't trust a fake for hardware or e-liquid quality.

Our Verdict on the Geek Bar Pulse X 2 50K

The Pulse X2 is the most complete Geek Bar Pulse model yet. It runs more efficiently than the Pulse X, and its screen gives you useful information. The Bull Edition also offers flavors that stand apart from the usual fruit-and-ice lineup. Yes, the 50K rating is optimistic for real-world vaping, but the same goes for most big-number disposables.

Who Should Buy It

• Heavy Vapers: You'll appreciate fewer device swaps and the bigger battery.
• Adult Smokers Switching Over: Pulse mode's stronger throat hit feels closer to what you're used to.
• Flavor Explorers: The Bull Edition is worth a try if fruit-and-ice flavors feel stale.

Who Should Skip It

• Beginners: 5% (50 mg/mL) is a lot if you're new to nicotine.
• Pocket-First Vapers: At 110 g and nearly 95 mm tall, it's a bulky carry.
• Low-Key Vapers: The light show won't win you any points for subtlety.
