Battle of the Boost: Lost Mary MT15000 Turbo versus Geek Bar Pulse

There has been a technological convergence with disposable vape devices. Most offer similar flavors, and the use of USB-C rechargeable batteries in now universal.

To stand out from the crowd, elaborate features and impressive displays have been added. The Lost Mary MT15000 Turbo Collection is one of the most recent disposable vapes to throw their hat in the ring. It features the high-quality flavors that has made Lost Mary a smash hit with adult vapers.

Holding court as an early adopter, the Geek Bar Pulse and its ballyhooed Pulse Mode brings an impressive level of wattage and a Smart LED Display to the game.

As outlined in our previous feature on the best performance boosted disposable vapes, there are a number of hard-hitting disposable vapes that offer huge puff counts and multiple modes.

Some rely on airflow control, like the popular Raz TN9000 disposable vape, which is so good we reviewed it twice. Check out our Raz TN9000 review and Raz TN9000 Dream Edition Review for more information.


Dual Mode Duel

Dual cores and dual modes are the story with many of this powerhouse disposable device. The Crazy Aces B15000 is a great example of this approach but today we are focusing on a duel between the Geek Bar Pulse and the Lost Mary MT15000 Turbo.

Tale of the Tape

It does not take a very close examination to see that not much separates these two devices in terms of performance. Both hold 16ml of nicotine salts, strength five percent, and both use dual mesh coils to offer a pair of performance modes. The Lost Mary MT15000 Turbo operates at 11 and 22-watts, while the Geek Bar Pulse at 10 and 20-watts.

Exactly how evenly they are matched is really laid bare in table form. As a reductionist exercise, there is very little to distinguish the two devices. But airflow, coil design, and the e-liquid contained within do make a difference. This is why some disposables are a smash hit and others languish on store shelves, ignored by adult vapers despite being available in the same popular flavors. 


Tale of the Tape: Lost Mary MT15000 versus Geek Bar Pulse


Visually, the Lost Mary looks like a buffed up MO5000 with a screen not dissimilar from a RabBeats RC10000. The Geek Bar Pulse has a huge and bright screen. That one is going to boil down to personal preference. As will the flavors, which will probably end up being the biggest differentiator for most adult vapers. The table above shows just how much overlap there is, and we have the full-specifications below followed by a deep-dive into the features.

Geek Bar Pulse

As something of the defending champion, or at least the most veteran, of this wave of boosted mods, it is fitting that we examine the Geek Bar Pulse first.

What sticks out first on the Geek Bar Pulse is the screen. Personally, I do not see the need for a large screen with a rocket ship, but it certainly is striking. I also question the inclusion of a flavor called Cancer Berry Bliss, fortunately with a constellation graphic on the side to add context. But there is no doubt it cuts a much more striking figure than the Lost Mary MO15000 Turbo.

Geek Bar Pulse Screen

The ergonomics are quite sound. The plastic is of softer variety, and this encompasses a more durable chassis underneath. It is not so soft at the rival dual mode Pyne Pod Boost, where you can clinch the disposable vape in your teeth and free both hands.

Pulse Mode and Regular Mode

The heart of the device is the dual coil design. Perhaps sounding a bit curmudgeonly, the author prefers the regular mode and doesn’t have much need for blasting away with a 5 percent strength salt. But the power on tap is impressive.

Geek Bar Pulse Coil

The 10-watt regular mode is far from a throwaway. Not only does it burn less e-liquid and less battery, but it does a great job at generating densely flavored vapor even when both the battery and e-liquid are getting low. In the words of the manufacturer, regular mode was engineered for high-flavor consistency on a low battery. And 10-watts is pretty much the bog-standard disposable vape experience and does not feel underpowered.

Geek Bar Pulse Interface

Modes can be toggled between with a switch on the bottom, the trademark rocket ship only appearing in Pulse Mode. Pulse Mode delivers as advertised, utilizing pulsating firing patterns like a sophisticated box mod.

If flavor preferences or draw are subjective, then form factor is barely worth mentioning. But truth be told, a smaller display that has all the same information seems like a win-win to me. The Lost Mary’s Smart Screen is easy to read without seeming inordinately wasteful on a disposable device.

Inside, the Lost Mary MT15000 Turbo also packs a dual core and a dual coil. This allows it to consistently churn out exactly one more watt in Smooth Mode and two more watts in Turbo Mode than the corresponding power options in the Geek Bar.


This level of difference is of course miniscule, governed by coil designs and shouldn’t be a deal breaker either way. The chipsets should keep them operating in this envelope, but it is frankly a power difference that is within the margin of error during most use cases.


Turbo Mode and Smooth Mode

Smooth versus Turbo Mode Lost Mary MT15000 Turbo

What there is no denying is that Turbo Modes is a lot punchier than smooth mode and totally changes the character of the device. In smooth mode, you have a slightly tighter MO5000 with 3x the puff count. In Turbo Mode, you have a very punchy MTL disposable.


Geek Bar Pulse versus Lost Mary Flavors

Here is probably where your decision should be made, and with no glaring errors and lot of bog-standard flavors being best-sellers, it is very hard to tell someone which disposable vape to buy based on the mint or blue raspberry ice flavor option. There are certainly reviewers who will act like some taste like “real fruit”, but the truth is that no one would want to wager too much on a blind taste test.

We have provided full reviews of every flavor in previous features. Our original Geek Bar Pulse Review covers their standard flavors. The New Geek Bar Pulse Flavors article heralds the arrival of a wave of constellation themed flavors. And finally, Seven New Geek Bar Pulse Flavors covers the rest.


Geek Bar Pulse Flavors

As you can see, this is an expansive list of flavors. Many are unique and not necessarily found in every competing device. Geek Bar has leaned in heavily on confection infused “Pop” flavors, based on nostalgic suckers filled with chewing gum. The even chose to use names that are close to trademarked, something we will refrain from putting into print.

As alluded to above, many of the Geek Bar flavors use constellation names. The reasoning behind this is a bit opaque. Perhaps the rocket ship and geek theme? But flavors like Gemini Grape Lemon and Leo Orange Cream are unique and flavorful. Orange cream in this case is an ice cream confectionary with smooth vanilla notes and sweet orange flavor. Their original line of flavors features planets rather than stars.

A solid honeydew flavor merits the name Virgo Crazy Melon and is also an excellent choice. Scorpio Blue Mint is a classic flavor with an excellent and composed blueberry base.

It is hard to argue with the quality of these Lost Mary Flavors. For an in-depth review of each flavor, check out our feature: Lost Mary MT15000 Turbo Review.

While there is nothing earth-shattering, and not much effort in the dessert realm like we have seen from Beard Vape Co. and their Fifty Bar and the RAZ TN9000, these are all rock-solid options. They also happen to be exactly the style of flavor that adult vapers prefer.

There is not a stinker in the bunch, and the flavors reliably deliver exactly as advertised. 

Our Verdict

This is going to be a split decision, largely determined by intangibles like draw-tightness and their slightly different takes on the best-selling flavors. The author prefers the Lost Mary MT15000 Turbo, for it dual mode personality of hard-hitting disposable and efficient all-day vape. The flavors are absolutely pristine, and there is plenty of variety. 

But there are flavor options available for the Geek Bar Pulse that you won't find a 1-to-1 replacement for with the Lost Mary. And it is a flashier and possibly more fun design. But for the business-like job of delivering satisfaction to an adult vaper, it is hard to argue against the intense power and smooth reliability of the MT15000 Turbo.
