What do watt, volt and puff counters mean in a vape?
Many modern vape devices display information on a screen. There you can see, among other things, watts, volts, puff count, battery level and sometimes also the coil's resistance. For those who are new to vaping, these terms may seem technical and difficult to understand.
The positive thing is that you do not need to be an electronics expert to use a vape. At the same time, it can be useful to know what the different values mean and how they affect the device's function. In this guide, we go through some of the most common terms displayed on modern vapes and e-cigarettes.
Why do some vapes display technical information?
Many vape devices are equipped with a chip that monitors and controls various functions. The screen is used to display information about the device's status and settings.
Simpler pod systems often only display the battery level, while more advanced vape devices can display watts, volts, puff count, coil resistance and other technical values.
The purpose is to give the user better control over the device and make it easier to monitor how it is used.
What do watts mean in a vape?
Watts are a measure of the power sent from the battery to the coil. The power affects how quickly the coil heats up and, consequently, how the e-liquid is vaporised.
On many modern vape devices, the user can adjust the wattage themselves. A higher wattage usually means that more energy is sent to the coil, while a lower wattage means that less energy is used.
Watts affect, among other things:
- How quickly the coil heats up
- How much vapour is produced
- How much battery is used
- How quickly the e-liquid is consumed
It is important to use a wattage range that suits the coil installed in the device. If you want to know more about recommended wattage levels for different coils, you can read our guide What wattage should I vape at?.
What do volts mean in a vape?
Volts are a measure of electrical voltage. In some vape devices, the voltage is displayed directly on the screen, while other devices manage this automatically in the background.
When the device is activated, the battery delivers a certain voltage to the coil. How much power actually reaches the coil is affected by, among other things, both the voltage and the coil's resistance.
For most users, voltage is not something that needs to be adjusted manually. On many modern vape devices, it is enough to choose the wattage, while the device adjusts the voltage itself as needed.
What is the difference between watts and volts?
Watts and volts describe different aspects of how a vape works electrically.
- Volts describe the electrical voltage.
- Watts describe the power used to heat the coil.
Many users focus primarily on watts because this is the setting that can most often be adjusted on modern vape devices.
Voltage, on the other hand, works more in the background and is used together with the coil's resistance to create the correct power.
What do ohms mean in a vape?
Ohms are a measure of the coil's electrical resistance. The resistance affects how much current passes through the coil and how it works together with the battery.
Coils are available with several different resistance levels depending on the type of use they are intended for. Some coils are used at lower power, while others are designed for higher power and greater vapour production.

What is a puff counter?
The puff counter is a function that records how many puffs have been taken on the device. Many modern vape devices have a built-in puff counter that automatically increases the number each time the device is used.
The purpose of the puff counter is primarily to give the user information about their usage over time. Some people use the function to get a better overview of how often the device is used.
The puff counter does not affect how the device works and has no impact on flavour, vapour production or battery life.
Why do some vapes have more settings than others?
There are significant differences between different types of vape devices. Simpler pod systems are often designed to work automatically without the user needing to adjust any settings.
More advanced devices, on the other hand, offer more functions and adjustment options. There, the user can, for example, adjust the wattage, lock buttons, view detailed battery information and monitor the puff counter.
Which functions are available depends on the model, manufacturer and type of vape.
Do you need to understand watts, volts and ohms to use a vape?
No, most users do not need to understand all the technical details to use their vape. Many modern devices are designed to work automatically and require very few settings.
At the same time, a basic understanding of watts, volts and ohms can make it easier to understand how the device works and why certain settings affect flavour, vapour and battery life.
For users who want more control over their vape, it can therefore be valuable to know the most common terms.
Frequently asked questions about vape settings
Is higher wattage always better?
No. The wattage that is most suitable depends on which coil is being used and what the manufacturer recommends.
Do volts affect the flavour?
Voltage affects how the device operates electrically, but most users adjust the wattage instead of the voltage.
Can you reset the puff counter?
On many vape devices, it is possible to reset the puff counter via the settings menu. The function varies between different models.
Do all vapes display watts and volts?
No. Many simpler pod systems do not have a screen at all and only display the battery level or charging status.
Things to remember
Watts, volts, ohms and puff counters are some of the most common terms displayed on modern vape devices. Watts describe the power used to heat the coil, volts describe the electrical voltage and ohms show the coil's resistance.
The puff counter is used to record how many puffs have been taken on the device and primarily serves as an information function.
Although you do not need to understand all the technical details to use a vape, a basic understanding of these terms can make it easier to understand how the device works and how different settings affect the user experience.
