Lost Vape OB5500 Disposable | Review

An exceptional disposable with bold flavor.

The Lost Vape OB5500 is the latest disposable vape offering from Lost Vape, joining the popular Orion Bar line of pre-filled disposables.

This sleek device packs a 14mL juice capacity and an estimated 5500 puff lifespan. It uses nicotine salts at a strength of 50mg (5%) for ample vapor and throat hit. 

An automatic draw activation and adjustable airflow slider provide ease of use. The OB5500 recharges via USB-C when its 500mAh battery runs low.

The Lost Vape OB5500 is available in 10 fruity flavors (see list below).We absolutely loved the Orion Bar 7500 when we reviewed it. So, let’s see if the OB5500 has the same pedigree.

The Bottom Line

Lost Vape has done it again. The OB5500 delivers an exceptional vape experience for a disposable. The flavor it delivers is bold, intense, accurate, and probably the best we’ve had from a disposable. The adjustable airflow is well executed and delivers from a tight MTL to a restricted DTL. We only wished the OB5500 had a more subtle design and a 20mg version – highly recommended.

Design & Build Quality

The OB5500 sports a slick but funky aesthetic, which is not too dissimilar to the OB7500. 

The main shell is plastic and smooth in the hand, but its compact shape still provides a secure grip. The device feels lightweight yet solidly constructed.

The OB5500 is slightly taller and broader than an Elf Bar BC5000 (EB Designs). It measures 82mm x 44.5mm x 22mm, which remains nicely compact for a disposable with a 14ml capacity. 

The size difference is pretty negligible; I only really noticed it when holding them side by side. It will easily slip into a pocket or bag for portable, discreet vaping.

Lost Vape OB5500 Disposable Mouthpiece

One thing I really love about the design of the OB5500 is the mouthpiece. It’s a tapered duckbill shape that’s extremely comfortable in the mouth and ideal for MTL vaping.

I’m less enamored with the overall out-there styling of the device.

The bottom third of the device is a solid color matching the flavor profile. The Lost Vape logo pops on the front of the section in a crisp white print.

This part of the design I really like.

However, the top section reveals some peculiar and colorful artwork behind the transparent shell.

There’s a character in what looks like a hazmat suit holding two pipes dripping with liquid. The flavor is then written in the bottom part of this section.

It’s the same on every device, just different color schemes to match the flavor profile within.

Some may find the design fun and unique, but it’s just a little too much for me.

I remember having similar feelings about the OB7500 design. I guess I just like my devices to be a little less in your face.

I’m glad to report that one of the best features of the OB7500 has also made its way to the OB5500, which is the airflow adjustment slider.

Lost Vape OB5500 Disposable USB Port & Airflow

It is located on the base of the device, along with the USB-C charging port.

I appreciate that the slider stays in place when adjusted, and having the ability to tweak the airflow to my preferred draw style is excellent.

Adjusting from the loosest setting to fully closed provides a nice range from restricted DTL to tighter MTL inhales. 

The single LED battery life indicator is also subtly integrated into the base. It briefly flashes when fired or charging, but like many disposables, it can be hard to see while vaping. 

Overall, the OB5500 checks the boxes for build quality, ergonomics, and features. The aesthetics are undoubtedly unique but might be a little dividing.

Lost Vape OB5500 Disposable Flavors


The OB5500 comes in a wide selection of fruity flavors. I got to test all 10 of Lost Vape’s offerings:

Lost Vape OB5500 Disposable Kiwi Berry

Kiwi Berry

Kiwi Berry is a symphony of sweet flavors balanced by the tropical tartness of kiwi and juicy mixed berries. The sweetness surpasses even Blue Razz, but it finds harmony with a cool, crisp embrace on the exhale. It delivers a gratifying blend of vibrant fruits and refreshing smoothness.

Lost Vape OB5500 Disposable Strawberry Dragon Fruit

Strawberry Dragon Fruit

This flavor fuses ripe strawberries and exotic dragon fruit. The initial strawberry burst gives way to the captivating sweetness of dragon fruit. It journeys between familiar and exotic fruits for a dynamic, palate-intriguing profile. It is an exciting interplay between two distinct flavors.

Lost Vape OB5500 Disposable Pineapple Coconut

Pineapple Coconut

Pineapple Coconut evokes a luscious creamy Pina Colada or coconut cream pie. The coconut leads, delivering a creamy essence reminiscent of coconut desserts. Unlike intense pineapple sweetness, it offers a coconut dominance with a pineapple accent. Subtle icy notes provide a clean finish.

Lost Vape OB5500 Disposable Blue Razz Lemonade

Blue Razz Lemonade

Here zesty blue raspberry meets sweet homemade lemonade. It weaves sweet and tart elements for a taste bud-tickling flavor. The raspberry and lemon dance across the palate, promising a refreshing and exciting experience.

Lost Vape OB5500 Disposable Creamy Candy

Creamy Candy

Creamy Candy indulges the sweet tooth craving classic creamy candies. It mirrors those luxurious, milky candies with irresistible smoothness. Each puff evokes nostalgic bliss for creamy confections.

Lost Vape OB5500 Disposable Kiwi Passion Fruit Guava

Kiwi Passionfruit Guava

This exotic blend combines guava, passionfruit, and kiwi tartness. It captures juicy fruit indulgence, delivering a vibrant sensory experience. The fruits intermingle for an exhilarating flavor symphony.

Lost Vape OB5500 Disposable Triple Berry

Triple Berry

Triple Berry explodes with three succulent berries, sending taste buds into new dimensions. The medley conjures a full-bodied, juicy berry symphony for the senses. It is an extraordinary flavor encounter.

Lost Vape OB5500 Disposable Strawberry Watermelon

Strawberry Watermelon

This timeless fusion blends watermelon and strawberry sweetness. Each puff encapsulates juicy watermelon with delightful strawberries, evoking nostalgic summer vibes. A flavor ode to the essence of the summer season.

Lost Vape OB5500 Disposable Pink Lemonade Mint

Pink Lemonade Mint

Pink Lemonade Mint spins the classic drink with tangy lemonade and refreshing mint. It makes for an invigorating and unique vape, encapsulating a cooling, zesty beverage. It’s a delightful twist on a timeless thirst quencher.

Lost Vape OB5500 Disposable Fresh Mint

Fresh Mint

Finally, Fresh Mint satisfies the craving for a clean, rejuvenating experience. Lose yourself in exhilarating crisp mint with an awakening cool rush. It is a pure, refreshing option for mint leaf enthusiasts.

Let’s get straight into it – the OB5500 is easily one of the best disposables I have tried this year!

I remember being blown away by the performance and flavor delivered by the OB7500, and I think the OB5500 takes it up a notch.

I don’t know what it is about Lost Vape’s flavors, but everyone is a banger.

I would try one flavor and think, ‘Wow, this is my favorite,’ until I opened the next disposable and thought exactly the same!

The ‘Fresh Mint’ was the only one that didn’t excite me, and that’s because I’m not really a mint guy.

As for the rest, they are all exceptional! I was constantly chain-vaping the Pineapple Coconut and Strawberry Dragon Fruit; they were just too delicious.

I feel like the flavor intensity on the OB5500 is bolder than many competitors I’ve tried recently. Even subtle notes come through clearly. 

Notably, the flavors also remain consistent from the first puff to the last, thanks to the mesh coil and 14mL capacity.

I hope Lost Vape starts making these in a 20mg nicotine salt mix because 50mg can be a little too much – especially when you can’t put the things down.

The thing that makes the performance so good is the adjustable airflow.

Sometimes, disposables can be a little too loose for me with the MTL draw. You can get the OB5500 to a really tight MTL by closing the slider down.

When fully open, the airflow can deliver a restricted DTL, which is great for a disposable. But I’m not crazy enough to be direct-lunging 50mg all day!

The automatic draw activation reliably fires up the device every time I inhale, with zero delays. It worked flawlessly, even under heavy usage.

As for battery life and puff count, both met my expectations.

The OB5500 efficiently delivered a full day’s worth of moderate vaping before needing a recharge. And charging speed via USB-C was nice and quick.

By providing bold flavor, adjustable airflow, and consistent performance, the OB5500 is easily among my top-rated disposable options right now.

The Lost Vape OB5500 has just gone to the top of my list of best disposables this year.

Yes, I wish the design was a little more subdued. But when the flavor and performance are this good from a disposable – I can look past that.

When it comes to flavor quality and intensity, the OB5500 is easily ahead of many competitors I’ve tried.

Having the ability to tweak the airflow to your preferred draw style is a significant plus and elevates the whole experience.

Battery life is decent, and the automatic draw activation works flawlessly. 

Lost Vape has managed to stand out in a crowded market, not just with the design of the OB5500 but, more importantly, the vape quality it delivers. 

The OB5500 is easy to recommend to any vaper, not just disposable lovers.
