IQOS 3 DUO Review

IQOS 3 Duo is a revolutionary tobacco heating system that offers an alternative to traditional smoking. Developed by Philip Morris International, IQOS 3 Duo is the latest addition to their line of IQOS devices. It is an upgraded version of the IQOS 3, with the main difference being that it allows two consecutive uses without needing to recharge the device.

How Does IQOS 3 Multi Works

The IQOS 3 Duo works by heating specially designed tobacco sticks called Heets, which contain real tobacco. The heating process is achieved through the use of an electronically controlled heating blade, which heats the tobacco to a temperature of up to 350°C. This process creates a tobacco vapor, which is then inhaled by the user.

Unlike traditional cigarettes, IQOS 3 Duo does not burn tobacco, meaning that it produces significantly fewer harmful chemicals and pollutants. This makes it a less harmful alternative to smoking for those who are looking to quit smoking or reduce their exposure to harmful chemicals.

A Closer Look at the Device

IQOS 3 Duo is a sleek and modern device that is designed to be easy to use and portable. The device is made up of two main components - the holder and the pocket charger.

The holder is where the Heets tobacco stick is inserted, and it is where the heating process takes place. It has a compact and ergonomic design that fits comfortably in the hand, with a single button on the side for turning the device on and off, and for checking the battery status.

The holder has an advanced heating blade that heats the tobacco to a temperature of up to 350°C, which is the optimal temperature for releasing the flavor and nicotine from the tobacco without burning it. This process creates a tobacco vapor that is inhaled by the user, providing a similar experience to smoking without the harmful chemicals associated with traditional cigarettes.

The pocket charger is where the holder is stored when not in use, and it is used to recharge the device. It has a sleek and compact design, making it easy to carry around with you wherever you go. The pocket charger can be charged using a USB cable, and it has an LED display that shows the battery status of both the holder and the charger.

One of the key features of the IQOS 3 Duo is its ability to be used twice in a row without needing to be recharged. This is achieved through the device's fast charging technology, which allows the holder to be charged in just a few minutes. This means that users can enjoy two consecutive uses without having to wait for the device to recharge.

The IQOS 3 Duo starter kit comes with everything you need to get started with the device. Here's what you can expect to find in the box:

  • USB Cable: This cable is used to charge the pocket charger, and it can be plugged into a computer or USB power adapter.

  • Turn on the Holder: Press and hold the button on the side of the holder for a few seconds until the LED light starts to blink. Once the light stops blinking and turns solid, the device is ready to use.
  • Enjoy: Inhale from the holder to enjoy the tobacco vapor. When you're done, remove the tobacco stick from the holder and dispose of it properly.
  • Recharge the Holder: Once you've used the holder, insert it back into the pocket charger to recharge it for your next use.

With these simple steps, you'll be able to enjoy the benefits of the IQOS 3 Duo and start your journey toward a smoke-free future.

Heating Technology and Understanding How IQOS Works

  • The IQOS uses a heating blade that is made of ceramic and gold, which is located in the holder of the device. When you insert a Heets tobacco stick into the holder and press the button to activate the heating element, the blade heats up and heats the tobacco.
  • The blade heats the tobacco to a temperature that is lower than the temperature at which it burns, which helps to reduce the number of harmful chemicals and toxins that are produced. The tobacco is heated to a temperature of around 350°C (662°F), which is significantly lower than the temperature at which tobacco burns, which is around 600°C (1112°F).
  • As the tobacco is heated, it produces a vapor that you inhale, which provides a similar experience to smoking. However, because there is no smoke, there is no ash or lingering odor on your clothes or in your surroundings.
  • One of the benefits of heat-not-burn technology is that it produces fewer harmful chemicals and toxins than smoking. Studies have shown that heat-not-burn products like the IQOS produce significantly fewer harmful chemicals than traditional cigarettes.

Flavor and Nicotine Strength - Reviewing the Available Heets

There are some popular flavors of Heets tobacco sticks available for use with IQOS devices, each offering a unique taste and aroma.

  • IQOS Heets Amber: This flavor is described as a classic tobacco blend with nutty notes and a warm, velvety taste. It is a popular choice for those who enjoy the taste of traditional cigarettes.
  • IQOS Heets Yellow: This flavor is a smooth and refined tobacco blend with a delicate aroma and light taste. It is a good option for those who prefer a milder taste.
  • IQOS Heets Turquoise: This flavor is a refreshing blend of menthol and tobacco, providing a cool and invigorating experience. It is a popular choice for those who enjoy menthol cigarettes.
  • IQOS Heets Sienna: This flavor is a full-bodied tobacco blend with woody and spicy notes, providing a rich and intense taste. It is a good option for those who enjoy stronger tobacco flavors.
  • IQOS Heets Bronze: This flavor is a blend of tobacco and cocoa, providing a rich and smooth taste with hints of chocolate. It is a good option for those who enjoy sweeter flavors.
  • IQOS Heets Green Zing: This flavor is a blend of menthol and lime, providing a refreshing and zesty taste. It is a good option for those who enjoy citrus flavors.
