Koi Delta 8 THC Vape Cartridges Review

If there’s one way in which hemp enthusiasts are choosing to experience delta 8, it’s through vape cartridges, which continue to reign supreme on the market.  Vape carts are easy to use, conveniently disposable, and capable of delivering delta 8 into the system in the fastest and most potent way.  Hence, we will be reviewing Koi Delta 8 THC Vape Cartridges today.

What Is Koi Delta 8?

Koi Delta 8 is a vape pen that’s been designed with a large-capacity oil cartridge system. Using Japanese engineering and the highest-grade materials, the makers of this vaporizer have managed to create a device that’s both durable and highly efficient. Let’s proceed to the Koi Delta 8 disposable review.

The Packaging

Koi always gets extra points for their packaging, for many reasons. One is that the package itself is extremely secure and childproof and offers all the information you need to know about what’s inside. Furthermore, the cartridge itself is extremely reliable, made with quality materials that ensure excellent performance as well as durability. Find out more about cartridge features later in the review. 

What’s in the Box?

When you purchase a Koi Delta 8 kit, you’ll receive the pen itself, an oil cartridge, a USB charging cable, a cleaning brush, and a user manual.

The oil cartridge is made using Japanese medical-grade glass and can hold up to 300 ml of your favorite vaping oil. The oil cartridge is what powers the Koi Delta 8 and allows you to vape until the cartridge runs out.

The Koi Delta 8 also comes with a one-year warranty. If you have any issues with the device, you can get in touch with the manufacturers for a replacement or a full refund. This little Koi Delta 8 vape review will help you better understand what to expect.

The Transparency

Koi is a company that highly values transparency, and many customers trust them because of how much information they provide when it comes to how their products are made. You’ll have no trouble finding information about how they extract their hemp, how they source the raw hemp material, and even the ingredients that they use, all of which give us a good idea of what to expect when we take the product.


Like many companies, Koi offers their delta 8 vape carts in many strains. The available strains are:

  • Super Sour Diesel;
  • Lemon Runtz;
  • GG #4;
  • Black Berry Kush;
  • Gelato.

This offers a nice selection of varying Indica and Sativa levels so you can customize your vaping experience according to the properties that you’re looking for. We will tell more about its features later in this Koi Delta 8 THC vape cartridges review.

Other Active Ingredients

The Koi Delta 8 THC Vape Cartridges do not contain active ingredients other than hemp. But they do contain full-spectrum hemp extract, which is why they all contain a huge variety of terpenes.

Refillable Cartridge System

A short Koi Delta 8 cartridge review will describe to you the main features of the disposables. The Koi Delta 8 is a pen-style vaporizer that utilizes a refillable cartridge system. Unlike other vaporizers that use a heating element, the makers of this device have opted for an oil diffusion method. This means that you’ll never have to purchase expensive cartridges again.

The oil Koi Delta 8 carts are made of high-quality materials made with Japanese technology, which means that the cartridge is durable, efficient, and easy to clean. The cartridge also has a one-year warranty.

To refill the oil cartridge, you’ll need to remove the mouthpiece and replace the cartridge. This can be accomplished easily with the provided instructions.

Overall Formula

Koi’s vape oil formula is one of the best on the market because of its exceptional purity. Each cartridge contains only 90% delta 8 THC extract and terpenes, with no fillers, additives, or cutting agents. This allows for a higher potency level per puff that many delta 8 vapers desire.

The Koi Delta 8 is a great device for beginner users and has high-quality components. It uses high-grade Japanese oil diffusion oil and medical-grade glass to ensure that the user’s health is protected while they use it. 


Lab-testing is a critical component of the hemp industry, as it allows companies to offer unbiased information about the quality of products to consumers. Koi engages thoroughly in this process by sending off each batch of hemp plants extract to a registered lab to have it rigorously tested.  The lab reports are available for customers who wish to learn more.

Koi Delta 8 THC Vape Cartridges

The Koi Delta 8 comes with three different size cartridges. These cartridges contain a varying amount of THC, which allows the user to choose the amount of psychoactive effects they want when they use it. The amount of THC in each cartridge is 2%, 5%, and 6% respectively. Each cartridge has an average weight of 0.5 g, and these take up around 30 cubic centimeters or 1 ounce of space in a regular-sized vaporizer or 3 ounces in a large vaporizer like the Vapir NO2. Ask for a doctor’s advice if you are not sure whether this product is right for you.

The Koi Delta 8 comes with a replaceable atomizer cartridge that is made from medical-grade stainless steel. This allows the user to be able to clean their device without having to purchase any additional parts. Furthermore, the device has a wickless design, which means that there are no wicks that can get clogged or dirty over time. The Koi Delta 8 also features a glass mouthpiece and a micro USB port for charging and connecting the device to your computer or smartphone via Bluetooth.

Flavor Profile

Koi’s THC vape cartridges are known for being particularly flavorful, which speaks of the quality of the extraction technique that they use, which preserves the delicate nature of each terpene present. Each cartridge has its own distinctive flavor profile which comes solely from the terpenes inherent to each strain, and each strain is delicious in its own way, with a fresh, rich, and clean taste.

The Koi Delta 8 has a flavor profile that is unique and excellent. This is because it uses Japanese oil diffusion technology, which allows the oil from the cartridges to be heated at very low temperatures. The device has 3 different temperature settings, which are suited for both novice and experienced users of vaporizers. The device also allows the user to vape when they are outdoors without having to worry about inhaling any harmful chemicals.

Type of Experience to Expect

The delta 8 carts from Koi offer a satisfying delta 8 experience that’s fast-acting thanks to the nature of vaping the compound. You’ll likely start feeling the effects within minutes of your vape session, and the effects are fairly potent because of this delivery method. The effects wear off after about an hour. During the time in which they’re active, you may find yourself feeling calm and uplifted, and mildly intoxicated without the paranoia associated with marijuana.

The Koi Delta 8 is a great device for both beginners and experienced users of vaporizers. The device has high-quality components and uses Japanese oil diffusion technology to ensure that the user’s health is not endangered when they are using it. 

The Vapor Quality of Koi Delta 8

Koi Delta 8 comes with 3 different vaporizer temperatures. The first one is called the mellow, which provides the user with a moderate amount of vapor. The second one is called the hot which provides the user with a lot of vapor, and the last one is called the Volcano which provides the user with an intense amount of vapor.

The oil cartridge of the device can be heated from 90 °C to 230 °C and has a 30-day warranty. It uses a Japanese oil diffusion method and ensures an intense flavor and smooth vapor. It is quite popular among CBD product lovers.

What Makes the Koi Delta 8 THC Vape Stand Out?

The Koi Delta 8 vape has a high-quality battery that allows the user to vape for a long time without having to recharge and lasts for at least 30 minutes. This vape cartridge features a ceramic coil, compatible with standart 510 threaded batteries. The device is also very easy to clean, which is one of its main advantages.


  1. High-quality components;
  2. Easy to clean and maintain;
  3. Great customer service with fast delivery;
  4. Excellent flavor;
  5. A durable battery that lasts for at least 30 minutes. 


  1. Difficult to load oil cartridge on first use; 
  2. Can’t adjust temperature settings;
  3. Can’t lock the device in place. 

Our Final Opinion

Koi Delta 8 THC Vape Cartridges are truly an exceptional product on the hemp market, offering the qualities of delta 8 that users crave in a clean, pure and flavorful way. With so many strains to choose from, you’ll have no trouble finding a cart that suits your needs.

It offers users the ability to choose between three different size cartridges, which can be used to adjust the amount of THC they want when they use their device. The device has a replaceable atomizer cartridge, and it also comes with a glass mouthpiece and a micro USB port for charging and connecting to your computer or smartphone.

The Koi Delta 8 vaporizer is definitely not the best vaporizer that you can buy on the market right now, but it is still great. If you’re looking for something that gives you more control over how much THC you get when you vape, then the Koi Delta 8 may be the perfect option for you. We hope that this Koi Delta 8 THC vape cartridges review will help you to make the right choice.
