8 Best Caffeine Vapes of 2024 (In-Depth Guide)

As caffeine vapes are relatively new to the market, you may have many questions about what to look for in a caffeine vape and how caffeine vapes work. We’re here to help!

In this article, we’ll review the top 8 caffeine vapes of 2024. We’ll tell you everything you need to know about how these work and answer some commonly asked questions.

1. HELO Air Caffeine Vapes

If you’re looking for a no-nonsense caffeine vaporizer without ingredients known to cause harm, there’s no better choice than HELO Air caffeine vapes from MELO Labs. We’ve carefully designed our diffusers to be much safer than the average vaporizer. We wouldn't have made it if we didn’t think this was the best caffeine vape on the market.

Wholesome Ingredients

We use only three ingredients: caffeine, organic vegetable glycerin, and natural flavors. All these ingredients are food-grade quality, and none are known to cause harm to the lungs when inhaled. You won’t find any diacetyl (associated with popcorn lung), vitamin E acetate (known to cause lung injury), propylene glycol (a petroleum derivative), or nicotine.

Hundreds of satisfied customers claim our vaporizers feel much smoother and less irritating than e-cigarettes or any other vapes they’ve used. These devices don’t produce a thick cloud of smoke that’ll have you coughing for days. The experience is very mild. If not for the burst of flavor, you’d barely know you vaped anything.

Tons of Awesome Flavors

Speaking of flavor, what makes our caffeine vapes stand out is the widest variety of flavors on the market. You’ll find everything from Pink Lemonade and Arctic Mint to Cherry Cola, but customers love the great taste of Gush the most (it tastes like STARBURST® candies.)

With so many options, you’re sure to find at least one or two you like. All our flavors are customer-approved, and we offer ten in total: eight in the original size and two more in the HELO Plus size, which offers twice as many puffs as the original.

Best Bang for Your Buck

Whether you choose the HELO Air or HELO Plus, you’ll get the best deal on this list. HELO Air devices cost just $15 per vape, while HELO Plus diffusers cost $25 each, so you’ll save even more money using the larger size. But even the smaller size offers better value than the other vapes on the list below.

Our original vapes deliver about 400 puffs per device, while the PLUS size offers up to 800. Each HELO Plus has — by far — the largest capacity of any device on our list. In addition to providing a larger capacity, our vapes also offer more caffeine per puff than other vaporizers.

You’ll get about 1.3 mg of caffeine every ten puffs. We know that doesn’t sound like a lot, but trust us — that’s all you’ll need when you inhale it. And it’s more than you’ll get from most other devices on this list.

Many coffee and energy drink aficionados can attest that they feel the effects of these vapes, and as a result, they save a ton of money on hot or cold beverages.

May Help You Quit Smoking

What’s more, our vapes may even help you quit your smoking or e-cig habit. As you’ll notice from reading the reviews, many customers have deployed these tools to help curb their use of nicotine, and many have been pleasantly surprised by how well our vapes work for this purpose.

Our vapes provide an excellent oral fixation smoking alternative for those who want to quit nicotine but enjoy the feeling of inhaling something. These vaporizers are small and thin, like cigarettes and e-cigarettes, but without any harmful nicotine.

2. Inhale Health Caffeine

Inhale Health Caffeine

The other pure caffeine vaporizer we’re including on this list comes from Inhale Health, a caffeine vape without extra ingredients. Like the HELO Air, Inhale Health devices contain only caffeine, organic vegetable glycerin, and natural flavors. These vapes don’t contain anything known to harm the lungs.

Unique Flavors

Flavor selection and price are the main differentiators between Inhale Health and HELO Air diffusers. Inhale Health offers only two flavors: Wildflower and Sunburst Orange. So, you won’t have nearly as many options if you go with Inhale Health.

But these flavors are unique — we don’t offer anything like Wildflower, so if that sounds appealing, you may want to try this company’s products.

Small Dose of Caffeine

The other big difference is the price. For $20, you get an Inhale Health device containing 300 puffs, so you’re paying a little more for about 25% fewer puffs than with a HELO Air. What’s more, a serving of 10 puffs on an Inhale Health device delivers 0.213 mg of caffeine, much less than the HELO Air.

Some people may be interested in a device with less caffeine. If you don’t have an elevated caffeine tolerance and aren’t sure how these devices will affect you, starting with a smaller amount may be wise.

You’ll also get a discount if you purchase a subscription. If you do, the price per device is still higher than what we charge for the HELO Air, but not by much. If you’re looking for a pure caffeine vape with very little caffeine and unique flavors like Wildflower, Inhale Health makes a vape that might be right for you.

3. Vitabar Energy

Caffeine vapes from Vitabar Energy contain a blend of caffeine, vitamin B12, l-theanine, and l-carvone (used for flavor). Their vape juice is also formulated with organic vegetable glycerin and propylene glycol.

A Blend of Ingredients for Energy and Focus

One dose of Vitabar Energy contains about 0.096 mg of caffeine. That’s even less than in the other caffeine vapes we’ve examined, but since you’re getting a mix of other energizing ingredients, you may not need as much caffeine.

Vitamin B12 is an essential nutrient crucial for energy metabolism, and there’s some evidence that you absorb it even better when you take it alongside caffeine (though studies haven’t been done on inhaling these substances). L-theanine is an amino acid that helps you focus while counteracting the jitters you might experience from caffeine consumption.

Long-lasting devices

The company claims you can get 450-500 inhalations per device, which is more than delivered with any other devices we’ve looked at (except for the HELO Plus). That said, you’re getting significantly less caffeine per dose, which might be up to 20 puffs.

Each Vitabar Energy vape is $20, comparable to Inhale Health devices but more expensive than the HELO Air. However, you’ll save a little money if you subscribe, bringing the cost down to $17 per vape. And you’ll save even more money if you buy in bulk. If you buy nine devices simultaneously, the price is comparable to HELO Air's.

One drawback is the need for more variety: These vapes only come in one flavor: citrus. It’s a nice flavor for the morning, and the company claims it has notes of mandarin orange, cassia, and lemon. But if you’re looking for more flavor options, you may want to look elsewhere.

If you want a caffeine vape with vitamin B12 and l-theanine, a small amount of caffeine, and a citrus flavor, Vitabar Energy vapes may be a good choice for you.

4. HealthVape Caffeine & B12 Vapes

Another type of vape that doubles as a vitamin supplement, HealthVape diffusers combine the stimulating effects of caffeine with the nutritional benefits of Vitamin B12 in a delicious citrus formulation. Designed to boost energy and mental clarity, these vapes use a proprietary formula free of harmful ingredients like vitamin E acetate and diacetyl.

Tested Ingredients

All HealthVapes undergo vigorous testing by Eurofins, a global independent leader in genomics and clinical studies. This screening ensures that all ingredients and devices comply with food-grade standards. They're also organic, vegan-friendly, and non-GMO.

Stock Up to Save

For those looking to buy multiple vapes, HealthVape offers an enticing discount when you buy in bulk, with up to 20% off when you purchase ten packs. Just remember that some users reported that the boost energy was less intense than that of other caffeine vapes.

5. Cloudy Caffeine Diffuser

This aromatherapy diffuser blends naturally occurring caffeine, mango, and vitamin B12. Cloudy Caffeine Diffusers are plant-powered devices that contain only natural extracts and scents. They're also vegan, cruelty-free, and rated for up to 600 uses per diffuser.

Supporting Mental Health

Cloudy is unique because a portion of its proceeds are donated to NAMI, the National Alliance on Mental Illness, an organization dedicated to creating support and awareness for those who need it most.

Over 1 Million Units Sold

Cloudy's numerous positive reviews make it stand out from the competition. Its caffeine diffuser has over 20,000 reviews, most of which are positive.

Interestingly, some reviewers state this diffuser helped them calm down and fall asleep. Whether this is due to customers mistakenly reviewing the wrong product isn't entirely clear, but it is something to be mindful of.

6. LUVV Inhealers Caffeine Inhaler

This 700-puff device contains caffeine, vitamin B12, l-theanine, and l-carvone. All ingredients are USP-grade, vegan-friendly, kosher, and non-GMO. Additionally, all LUVV devices are lab-tested for safety.

LED Indicator Light

There's nothing worse than reaching for an inhaler only to find it's empty. Thankfully, LUVV uses a convenient LED indicator light to let you know when to go for a new device. Just keep in mind these are disposable devices that cannot be recharged.

Puff Count May Vary

One thing worth noting is that some reviewers felt the devices didn't last as long as they expected. One reviewer mentioned that theirs only made it about five days before running out. Unlike many other brands, there is no discount incentive for buying more than one unit.

7. Solstice Caffeine Diffuser

Those looking for a healthy and eco-friendly option need look no further than Solstice Caffeine Diffusers. These diffusers use all-natural ingredients and just enough caffeine to keep you awake when you need it — while allowing you to easily sleep when you don't.

Fruity Ingredients

While many brands opt for a simple two or three-ingredient formula, Solstice is fearless in getting creative. These diffusers contain lemon oil extract, menthol, cranberry extract, guarana berry, and maltol (a naturally occurring flavor enhancer).

Healthier Than a Cup of Coffee

For those who think a cup of coffee has too much caffeine, the Solstice diffuser contains 40 mg spread across 400 puffs. It's also free of the added sugars found in most commercial coffees or energy drinks.

The only thing worth noting is that some customers have yet to receive their diffusers after placing their orders, so potential buyers may want to ensure their delivery details are in order before purchasing.

8. Inhale Vitamins Energy

Lastly, these alternative energy vapes from Inhale Health also offer a mix of caffeine and other energizing ingredients. They contain a blend of caffeine, guarana, and vitamin B12, as well as vegetable glycerin and natural flavors—unlike the Vitabar Energy formulation, there’s no propylene glycol.

Highest Dose of Caffeine

With 1.5 mg of caffeine per 10 puffs, these vapes offer the most caffeine on this list — slightly more than what you get from HELO Air. That said, these devices won’t last as long as any of the others, with only 200 puffs provided. But this is the way to go if you want your caffeine as concentrated as possible.

A Blend of Caffeine and Guarana for Maximum Stimulation

Vitamin B12 can enhance your energizing experience (as we’ve already seen). But the unique selling point here is guarana: This plant native to the Amazon is often touted for its stimulating effects. It is also said to promote weight loss and mental focus. Alongside caffeine, it’s sure to energize you.

Three Unique Flavors

Inhale Vitamins energy vapes come in more flavors than Vitabar Energy or Inhale Health devices (but not as many as HELO Air products.)

You get to choose between Banana, Blue Raspberry, and Peppermint. You won’t find those flavor options from any other company, so if any of those sound appealing, you may want to try these vapes.

How Caffeine Vapes Work

We’ve just seen what’s in some of the top caffeine vapes on the market, but you might still have questions about how exactly these devices work. This section will answer some commonly asked questions about caffeine vaporizers.

Small but Efficient Dose of Caffeine

One of the first questions people tend to have about caffeine vapes is precisely how much caffeine they contain.

As we saw above, a regular dose will contain anywhere from 0.2 mg to 1.5 mg. Compared to a cup of coffee (around 90 mg), this might seem like nothing — but your body will absorb this vapor much more efficiently than the caffeine you ingest in food or drink.

With this in mind, figuring out the correct dose with a caffeine vape might take some experimentation. Most of these devices claim one dose is ten puffs, but customers often feel the effects after just two or three puffs. There’s little concern about consuming too much caffeine with these devices, but it’s still a good idea to take it slow at first.

200 to 400 Hits Per Device

As we saw above, the total number of hits or puffs per device varies, but it’s usually between 200 and 400 (though the HELO Plus offers 800).

Considering that a dose is usually ten puffs, most devices will last between 20 and 40 uses — around a month if you use them once daily. This load makes them much more cost-effective than buying a cup of coffee (or several) daily.

What Happens When You Vape Caffeine

While scientific research has yet to catch up, based on anecdotal evidence, caffeine vapes are much faster-acting than any other caffeine supplement on the market. You can feel the effects within just 10 or 15 minutes.

Vaporizers bypass your digestive system. Whereas caffeinated beverages, caffeine gummies, and caffeine pills all have to pass through the many organs of your digestive tract and be broken down by your stomach before making it into your bloodstream, caffeine vapes get to your bloodstream directly from your lungs.

Anecdotal evidence suggests there are few side effects of inhaling caffeine. Very few people find caffeine vaporizers irritating, partly because these vapes tend not to contain harmful ingredients in other vaporizers like e-cigarettes. As a bonus, all these vapes are vegan-friendly.

Where Can You Buy Caffeine Vapes?

Caffeine vapes can be purchased from various retailers online and in some physical stores. Many brands, including HELO Air, Inhale Health, and HealthVape, sell directly from their websites. Other online platforms and specialty shops or "superstores" also sell vapes from many brands.

If you want a comprehensive list of all the places you can purchase, please read this article. Wherever you decide to shop, always make sure you are buying from a reputable source to ensure authenticity and safety.

Are Caffeine Vapes Safe?

The safety of caffeine vapes can vary depending on the ingredients and the manufacturer. Many caffeine vapes are designed to be safer alternatives to smoking traditional tobacco products. For the safest vaping experience possible, try to avoid harmful chemicals like nicotine and opt for a vape that uses food-grade ingredients.

Keep in mind that because vapes are a relatively new product, their long-term health effects are still being studied. Buyers should look for products that list their ingredients and are transparent about their practices. Check out this article for a comprehensive look at caffeine vapes' safety, side effects, and risks.

How It Feels to Vape Caffeine

The short answer is that you have to try it for yourself! But if you want to know how others describe the feeling, it’s a much smoother, mellower experience than consuming a highly caffeinated beverage. You’ll definitely feel energized, but you won’t get jitters or crash later. And your lungs aren’t likely to get irritated like they might from other vapes.

So, caffeine vapes are a great way to help you stay awake and perform your daily tasks. You’ll feel energized without the unpleasant side effects that come with ingesting much more significant amounts of caffeine from other caffeine supplements.
