PWM (pulse width modulation) is a simple type of Regulated Mod that allows you to adjust how much power goes to your coil. Pulse Width Modulation works by quickly turning power off & on (in pulses) at a desired rate in order to create a lower average voltage output. This simple power design allows users to easily adjust the power and can extend the life of your battery charge since PWM mods to not run the vape coil constantly.

How many watts does a box mod use?
To create dense clouds of vapor with cannabis concentrates, a box mod should at least put out about 150 watts. A higher wattage will drain your battery more quickly, but the overall battery life is related to the milliamp-hour (mAh) rating of your battery.
What does wattage mean in a battery?
Wattage: Wattage refers to the electrical power your battery is capable of outputting to the heating element in your device. In general, the higher the wattage, the higher the vapor production, though the true result depends on several other factors as well.
How does a PWM vape work?
Basic PWM Theory#N#First a little bit of the basics ... PWM works by repeatedly turning power off & on at the desired rate so that the average power can be a specific % of the available power. For PWM vapes that means if you have 8V batteries running with 50%, how have an average of 4V, 75% would be an average of 6V. By adjusting the on/off ratio up or down you can get almost any effective power. You just have to remember that the batteries and switch (usually a MOSFET for vapes) needs to be able to handle the maximum current of 100%#N#How fast you do the pulses makes a difference once you get practical. High speed pulses make the average smoother, but ,most high current MOSFET's can have limits to how fast they can switch. On top of that, the more often the MOSFET switches the hotter it will get because while it is turning off or on is when most of the heat is generated in PWM circuits. Another factor that comes up is that PWM vapes can make noise, from a low buzz to a high pitch whine that can irritate people. That means that personal preferences are also factors in PWM frequency.#N#Finally there are additional technical issues in specific designs caused by specifications and voltages involved that become additional factors, for example the lower the voltages you are working with the slower you should switch the MOSFET off & on to reduce heating because the parts take longer to turn off & on at lower voltages.#N#Most simple PWM systems used with vapes will have a simple adjustable resistor you change to set what the on/off percentage in. It can be a pot on or through the case or a more precises multi turn trimpot. There are advantages and disadvantages to both types of pots. Since the PWM's power is based on % of the voltage, as your batteries drop, you may find yourself adjusting the PWM, and you definitely will want to adjust it each time you change the vape coil (s).#N#Final note: many more complex regulated mods at their core still use PWM to control the power going to the coils. Their difference really is in how the PWM is controlled more automatically by taking into account the battery levels or the actual temperature of the coil. Often those are using computers to intelligently adjust the PWM signal to give you the desired power.#N#more to follow ...
Why use a low side MOSFET driver chip?
Instead of just using a PFET buffer, a low side MOSFET driver chip is use to provide faster switching of the power MOSFET in both directions. The MOSFET pull-down then becomes a safety feature, not a required part for proper PWM operation and is usually a much higher value to improve the switch times.
Does a syslog have low voltage detection?
No, it doesn't have any type of low voltage detection so it can be used in a wider range of builds without people having to mess with re-configuring for different voltages.

How so? The board puts out the current voltage level of the batteries, there is no buck or boost.
Vape Mod Pens and Advanced Personal Vaporizers – Are They the Same Thing?
One question that we get asked often is: “are vape pen mods and Advanced Personal Vaporizers (APV’s) the same thing?”
Vape Mods 101: The Basics
Like we mentioned, vape mods are essentially just “beefed up” versions of cheap e-cigarettes. But what exactly do we mean by “beefed up?”
Vape Mods and Temperature Control
You might think that the e-coil on a vape mod can heat to much higher temperatures than a disposable vape pen can, but, in reality, the opposite is true.
Vape Mod Components
The unit containing both the heating element and the wick is called the atomizer.
Hundreds of Different Types of Vape Pen Mods to Choose from
There are hundreds, maybe thousands, of different vape mods out there (brands, models, etc.). Also, you can use many individual components to build up your own customized vape pen mod.
Origins: How (and Why) Did the Vape Pen Mod Come to Fruition?
The origins of the vape mod came about because of the limitations of disposable e-cigs and vape pens. Consumers wanted something more powerful, which could deliver a more potent hit than any vape pen was able to provide.
Rookie Vapers: Should You Start With a Vape Pen Mod?
Like we mentioned earlier, it is totally up to you what vaping device you choose. You could begin with a more expensive vape mod. Alternatively, you could do what most people do and purchase a cheap, disposable vape pen. This will give you a good idea of what vaping is all about.
Tube vs. Box
The first differentiation in mod style is the form factor. Tube mods are cylindrical in shape, about an inch in diameter, and four or five inches tall. They're shaped like a vape pen, but much bigger. Some have built-in rechargeable batteries, others are simply a tube to hold a replaceable 18650 high-discharge lithium ion battery.
Stick Mod
A newer, in-between form of mod that's gained popularity in recent years is the stick mod, a tube mod that doesn't have the adjustability of a more advanced regulated device but retains some of the safety protections. These frequently come with a vape tank as part of an all-in-one (AIO) starter kit and fixed rechargeable battery.
Squonk Mod
Finally, there are bottom feeder, or "squonk" mods. These look like box mods, but with one notable difference. Instead of using a clearomizer tank or traditional rebuildable dripping atomizer (RDA), these models have a bottle of e-liquid housed in the same body that holds the battery and (if applicable) chipset.
