A Deep Dive into Modern E-Cigarettes

As the vaping industry evolves, so does the technology behind e-cigarettes. VODO BAR has been at the forefront of this innovation, particularly with the introduction of variable wattage e-cigarettes. These devices allow users to adjust the power output, tailoring their vaping experience to their preferences. Let’s explore the mechanics and benefits of VODO BAR’s variable wattage technology and how it enhances the user experience.

Understanding Variable Wattage E-Cigarettes

Variable wattage (VW) e-cigarettes enable users to adjust the power output within a specified range, typically between 6W and 40W. Traditionally, such devices were known as “big vapes” due to their large size and the significant vapor production at higher wattages. However, advancements in technology have allowed these powerful devices to become more compact and user-friendly.

How Variable Wattage E-Cigarettes Work

The ability to adjust wattage in e-cigarettes is primarily governed by the PCBA (Printed Circuit Board Assembly) inside the device. Here’s a step-by-step look at how this technology functions:

  1. User Input: The user sets the desired wattage through the device’s control interface. This can be done using buttons or a touchscreen, depending on the model.
  2. MCU Processing: The Microcontroller Unit (MCU) receives the user’s input and processes it according to pre-programmed algorithms. This is the brain of the device, ensuring precise control over power output.
  3. Power Adjustment: Based on the input, the MCU adjusts the power management chip, which regulates the voltage and current supplied to the atomizer. Since wattage (W) is the product of voltage (V) and current (A), adjusting these parameters controls the power output.

Technical Overview:

  • Voltage Control: The voltage is varied to achieve the desired wattage. Higher voltage means

more power and larger vapor production, while lower voltage results in less vapor and a cooler vape.

  • Current Regulation: Current adjustments ensure that the atomizer receives the right amount of power without overheating. This is crucial to prevent issues like burnt hits or “spitback.”
