It delivers big-time value, great flavor and satisfying performance. Utilizing draw-activation, and potent salt nicotine, it works right out the box and easily outperforms Big Tobacco's prefilled pod kits by any meaningful metric.

Adult vapers prefer their vapes to have sweet and icy rather than faux-tobacco notes, and Lost Mary has done an exceptional job of developing bold flavors.

The Fifty Bar is a new face on the scene, although powered by Beard Vape Co. the Fifty Bar Disposable Vape Collection offers several flavor profiles that predate the market launch of nic salt disposables.

Its size, shape and performance are all similar to the Lost Mary OS5000. Its big claim to fame is that it is filled with US-made e-liquids and assembled in the US.


Fifty Bar: Assembled in America

The Lost Mary OS5000 is one of the most popular vapes in America, their sharp flavors appeal to the American palate and they are one of the most popular disposable vapes in the US. But they are not an American assembled product. Fifty Bar feels this will give them an edge on the competition.


Fifty Bar Nic Salt Flavors: Manufactured in US by American Formulators

One of the new lines of attack formulated by vaping prohibitionists and Big Tobacco is that disposable vapes are manufactured in China (as are the prefilled pod kits of Big Tobacco). The Fifty Bar knocks down that argument. Assembled in the US, it is filled with American made nic salts that have been formulated by American masters. Several Beard Vape Co.'s classic flavors are available in the Fifty Bar Disposable. For a complete run-down of their flavor line-up, check out our Fifty Bar Disposable Vape Review.


Disposable Vape Flavor Comparisons

When comparing disposable vapes, it is important to note the similarities between the many devices on the market. They are all prefilled, draw-activated and feature potent nic salts to provide a satisfying experience. These shared traits are why they are so popular with adult vapers. 

Regarding flavors, there is generally a huge amount of overlap. To dust off an old pun, any disposable make worth its salt (nic) probably has a delicious blue razz, mint, mango, strawberry and watermelon vape in their quiver. Obviously, these flavors are not made from cold-pressed fruit, they are relying on a similar selection of artificial flavorings. This includes tobacco, which despite what flavor ban advocates suggest is just as much an added and artificial flavor as the most cloying spun sugar confection you could ever dream up.

Differences arise in the application of these great vape flavors and the performance of the disposable vape. While under similar constraints, there is also quite a bit of variance in the flavor quality, and vapor production of disposable vapes.

The straight talk is that wagering money in a blind taste test between ten blue razz disposables that are fully charged is probably a losing gambit. This is not necessarily a bad thing. If your favorite blue razz flavor is out of stock, you can always check out our Best Blue Razz Vapes page for some awesome tasting alternatives!

Disposable Vape Performance

Most disposable vapes, including the Lost Mary OS5000 and the Fifty Bar, are powered by rechargeable lithium-ion batteries. These batteries operate at a nominal voltage of 3.7 volts. It's essential to note that while this voltage is a standard across many disposable vapes, the actual power output can vary as they decrease in charge.

The output is not to be mistaken with milliamperes (mAh), which is a measure of the batteries capacity. This number can vary somewhat significantly between similarly sized disposable vapes. While approximately 600mAh is standard, they generally range from 450mAh to 750mAh.


Disposable Performance Differences

Several factors influence the power output, such as the level of charge, resistance of the atomizer coil and the efficiency of the device's internal circuitry. Therefore, while the battery voltage might be the same across different brands and models, the actual vaping experience can vary considerably.

Coil resistance plays an outsized role in the disposable vape experience, they must be durable as they have to last thousand of puffs and provide credible performance until the end. They also generate vapor, with lower resistance coils generating more vapor but burning through both battery and e-liquid faster.

Airflow is another key. Both in terms of how fast the draw-activation ramps up the coil and how much outside air is mixed into the vapor. A few disposable vapes, like the Lost Vape Orion Bars, offer adjustable airflow. Most give you no more control than an air hole to cover with your finger. As wattage cannot be adjusted, generally the "factory preset" is close to optimized, vapers seeking just a bit more performance will manipulate the airflow whenever possible for marginal gains in flavor and vapor density. 

Disposable vapes are close enough in performance where any comparison is subjective and will often boil down to flavor preferences, but there are empirical differences between the Lost Mary OS5000 and Fifty Bar to be hashed out first.

Fifty Bar Disposable Vape Review

The Fifty Bar is a robust yet compact disposable vape which is assembled in the US. Including the mouthpiece it is but 3.11 inches tall. While the specs are not provided, the coil resistance appears to be around 1.2 to 1.4, equivalent to a typical prefilled pod or disposable.

Fifty Bar Specs

The Fifty Bar is actually a smidge smaller than the EBCreate B5000 and Lost Mary OS5000, with a greater e-liquid capacity. This was made possible because the battery is not quite as long-legged, although still sufficient for plenty of puffs.

The use of an anti-burn coil is huge in a disposable of this size. Nothing is more demoralizing than a great disposable vape suffering flavor fade or a burnt coil long before it is empty. Expect these types of designs to be incorporated everywhere going forward. 

If you are looking for massive vapor clouds, a 50mg nicotine strength disposable device is not the right call. They are meant to be flavorful, discrete, and satisfying. Yet wispy puffs won't stand either and the Fifty Bar has a nice draw and is capable of churning out moderate cloud of vapor. It is still a mouth-to-lung vape, meaning that the tightness of the draw is roughly akin to a disposable, and quite different than the open airflow vape mods, which may be operating at four and five-fold higher wattage, and correspondingly require lower nicotine vape juice.


Review: Fifty Bar Flavors

Of course the Fifty Bar's primary selling point is not the hardware, which while assembled in America is technologically indistinguishable to a large extent. What matters are their flavors, formulated by American masters for American palates. If you think the word "American" is used too much, check out their promotional material!

Fifty Bar has a nearly perfect mix of the heavy hitters of the disposable vaping world and legacy Beard Vape Co. flavors. These are the style of flavorful dessert vapes that many disposable vape companies just don't execute that well. There is no covering up a botched donut flavor with a massive gust of ice in the same way you can swamp a basic mango with coolness.


Beard Vape Co. Legacy Flavors

While many disposable vape users aren't going to know Beard Vape Co. from Adam's Ox, the quality of Strawberry Cereal Donut Milk, Blueberry Cereal Donut Milk, Vanilla Custard, and Cinnamon Funnel Cake absolutely pop. These aren't half-baked flavors the brilliant nic salt descendants of some of the best freebase juices on the market eight years ago. They translate almost perfectly to the MTL style and lower vapor production of a disposable vape.

For those who do remember Beard Vape Co. from mod using days, Tobaccocino Fifty Bar is Beard Vape No. 00, and Cinnamon Funnel Cake is Beard Vape No. 32 inspired. The confusingly named "The One" collection by Beard has three entrants on the list, Vanilla Custard and the two donut milk vapes.


Fifty Bar's Classic Disposable Vape Flavors

There are five legacy Beard Vape Co. adjacent flavors for the Fifty Bar and four slamdunk disposable vape classics that they would have been fools not to offer. The Mint Fifty Bar is sweet and cool, bringing a hard-shelled mint flavor to the table which is refreshing and never tires the taste buds. The Juicy Mango Fifty Bar is bursting with powerful fruit and confection flavors, the best mango disposables offer such a great depth of flavor without being too sweet. It is in that category.

The nostalgic and sweet notes one expects in a blue razz are present in the Blue Razzle Fifty Bar, with the significant flavor burst one demands from a disposable vape. The Aloe Grape Watermelon Fifty Bar has soothing aloe and cool notes that cut through and enhance a purple grape delight mixed with sweet watermelon flavor.

Lost Mary OS5000 Review

With consistent performance, a durable mesh coil, and a great selection of flavors, the Lost Mary OS5000 is one of the standard-bearers in the disposable vape industry. It has an amazingly convenient design, is long-lasting, and can fit easily in the palm of your hand. The OS5000 is a light and unobtrusive disposable device that kicks out consistently delicious flavors.

Lost Mary OS5000 Specs

The ample vapor production of this design has also been a consistent selling point. The game totally changed when rechargeable disposable vapes took off in popularity. Not only could they fit far more e-liquid but you can keep them charged and firing at full power. Compared to a basic nic salt filled disposable vape bar or vape pen that cannot be recharged, the OS5000 immediately stood out as superior. There is more competition now but the Lost Mary OS5000 is still among the best when it comes to blending dense flavor with respectable vapor production.


Lost Mary OS5000 Flavor Review

As mentioned above, our guide to the Best Lost Mary flavors is your go-to for information on the options available. It merits a feature article unto itself because there are that many great options. The list above was taken from that feature, where rankings were determined by popularity and expert reviews.

There are no real limitations to the quality of the variety of Lost Mary flavors. While Fifty Bar has Lost Mary beat in the narrow range of dessert vapes, The One inspired donut vapes being awesome, the Lost Mary OS5000 has multiple options to compete with every opposing flavor. This includes plenty of flavors not yet on the radar of Fifty Bar. These these include Black Mint and frigid options like the Cherry Banana Duo Ice and Pineapple Duo Ice Lost Mary OS5000 Disposable Vape.


Conclusions: Lost Mary OS5000 versus Fifty Bar Disposable Vape

It is hard to argue with a product assembled in Thousand Oaks, CA that is providing US jobs. The use of Beard Vape Co inspired flavors is a bonus. With a slightly smaller size and classic iced fruit fusion options to cover other popular flavor options, the Fifty Bar is a formidable entry in the disposable vape arena. 

It gives up a bit of battery capacity to obtain a smaller size, but effort was put into perfecting both the draw and the flavors being puffed on. 

But Lost Mary has a much more comprehensive selection of flavor options and the benefit of familiarity, which is not to be underestimated when subjectively comparing flavors. One on one, The One inspired dessert donut flavors stand tall against any comparable flavor but the depth and breadth of Lost Mary line-up is tough to beat. The Lost Mary coils in my experience are stout enough so that the lack of anti-burn tech is not a deal breaker. 


Disposing of Disposable Vapes

These are a pair of tasteful and pared down disposable vape designs, so need not be admonished for leaning in a little too heavily on strange images or fonts. But this does not make them any more attractive when tossed in the street in the form of litter. 

We all know that vapers and the vaping industry have a PR problem, which has resulted in adults being denied access to the flavors they prefer. The result has been a calamity. An FDA sponsored study has found that vape sales decrease in areas with flavor bans and cigarette sales increase

Showing appropriate care and respect for disposable vapes is the very least we should be doing. They must be kept out of reach of children and pets. 

Disposable vapes are powered by lithium-ion batteries and should be treated like any electronic device. Curious if your Orion Bar 7500 is as tough as the Go-Pro case it resembles? Don't spike it on the ground to find out. Don't leave it by the curb when it is dead. Don't wrench it apart with a screw driver. 

The safe operation and disposal of disposables is crucial. Improper disposal not only contributes to environmental pollution but reflects poorly on an already embattled industry.

All manner of untrue myths swirl around disposable vapes and the adults that use them. A brightly colored disposable vape and its packaging stick out like a sore thumb when littered. So just don't do it. 

Here are some steps to ensure you're disposing of your disposable vape responsibly:

  1. Deplete the Battery: Drain the battery as much as possible, balancing the e-liquid and battery levels is easier on a device like RabBeats RC10000 which monitors both. 
  2. Locate a Recycling Facility: Many electronic waste recycling facilities accept disposable vapes. Look up local recycling programs in your area and drop off your used device there.
  3. Dispose of in Regular Waste, if Necessary: If you can't find a suitable recycling facility, dispose of the vape in your regular household waste. However, avoid littering at all costs.
  4. Spread Awareness: Encourage fellow vapers to dispose of their disposable vapes responsibly. As a community, we can contribute to a cleaner and healthier planet.


Lost Mary OS5000 and Fifty Bar Alternatives

Flonq Max Disposable

On the disposable vape front, the Flonq Max is an obvious alternative to both of these great devices. With flavors that equal or exceed any rival, it generates an honest 6500 puffs and has a carefully crafted design that is not garish or kitschy. Perfect for initiate vapers. More importantly, it just performs perfectly and has robust vapor production. 


Refillable Vape Pod Kits

Shop Pod Kits

If you are looking to save money and generate less waste, consider switching to a refillable vape pod kit. Modern refillable pod kits can handle both lower nicotine freebase e-liquids and the exact same style of nic salts found in disposable vapes. They are also easier to use than ever, with the old air bubble filling issues largely an issue of the past. In any event, the amount that you can save for the extra 30 seconds it takes to fill a pod is substantial. They are durable and when the coil is worn out, you can either punch in a new coil or swap in a new pod depending on the model.
