Comparison Report of KT&G's Vaporizers: Complex Technical Analysis and Test of Tobacco Vaporizers of Brand "LiL"

This report provides detailed technical information about the heat-not-burn type of vaporizer devices offered by KT&G Corporation. Information provided includes a technical properties comparison of HnB devices and device performance ratings that was calculated according to the author's in-house methodology.

The list of devices which are pass the research in this report are follows:

• LiL Solid Plus+
• LiL Solid Mini
• LiL Hybrid
• LiL Hybrid 2.0
• LiL Solid 2.0

There is no common technological pattern in the use of certain device heating elements in the production of units from the leading tobacco companies. Heated tobacco devices offered by KT&G include regular and hybrid heating systems. KT&G Corporation has several innovations identified in tobacco heating vaporizers of the brand "lil hybrid". All aspects of performance, construction, and technical components are compared.

Technical reviews are performed in order to identify innovations, advantages and disadvantages of devices. For an objective and comprehensive research, a set of tests are used that provide information about the operating characteristics of the device in different work modes.

Such tests and review carried out include:

• Internal components view. This part of the report shows the inner construction of devices.
• Heater review. The information provided in the report gives an idea of which types of heaters are most often found in devices from leading manufacturers, and what characteristics these heaters have.
• Airflow review. The detailed review of airflow design helps to understand the efficiency of their structure, ways of air heating and allows you to compare HnB devices airflows designs.
• PCB review. This part of the report provides analysis of electronics components which are used in HnB devices.
• Feeding signal type and temperature control system analysis. Researching of electrical signals on heater contact gives information about availability or non-availability of temperature control, feeding signal type and specific heating algorithms.
• Temperature deviation of heater shows how temperature of devices changes during the session. Information about the temperature of the heater provides the opportunity to make conclusions about the efficiency of the temperature control system and stability of devices parameters.
• Current consumption of device. This test shows how much power devices consume and shows their reaction on temperature control system activity. As a result, information of average and maximum consumption of current becomes available.
• Battery analysis. This test gives information about the quality and properties of batteries which are used in devices.
• Battery and device energy efficiency. This test shows how long devices can be active on one full battery load and how long it takes to get a full charge. It shows the efficiency and economy parameters of devices.
