Things To Look For When Buying
If you have been vaping for a while, then there’s a good chance that you have tried a lot of the products on the market. The basic types of 
hardware are easy enough to use that there is no need to read a manual or technical specifications. However, staying within this range robs you of the opportunity to have a better vaping experience. Check out the more advanced models called mods. These are highly customizable devices that are packed with features to help you get the most out of every puff. When buying one, be sure to consider the following factors:
Design, Size, and Shape
These come in a wide range of shapes and sizes. While most low-level e-cigs adhere to the cylindrical shape of analog cigarettes, mods tend to be boxy because of the circuitry contained in them. They thus look more like a pack of cards or a thick smartphone but with a short pipe on top so that users can inhale the vapor. Find one that suits your preferences when it comes to design. Smaller ones are easier to carry around while big ones have larger tanks to longer use. Some feel better in the hands while others are slippery with awkward buttons.
Materials
Consider the materials used in building the device as well. The cheaper options may use plastic for the out shell to reduce manufacturing cost but this tends to crack and warp easily. Shells made out of metal are much better as they remain intact even if you accidentally drop them on the ground. You can place them anywhere while traveling without worrying whether they will get scratched or cracked. Some models even use wood for a unique design, good hand feel, and insulating properties. Of course, all materials have their pros and cons especially when it comes to this application.
Battery Capacity
Check what kind of battery is being used in the device. Most will have a standard Lithium-Ion, Li-Mr, or LiFePo4 piece inside them while other manufacturers will create their own to fit their product’s non-standard shape and size. Standard batteries are great as you can readily purchase replacements if you lose them or if you want to carry a spare on the go. Proprietary batteries are much more expensive because there is no competition. However, they may make up for it by providing higher capacity, faster charging, and other kinds of performance boost.
Screen Displays
A lot of mods feature screen displays that flash important information on the screen. This can be a simple small monochromatic window or a larger one with full color. The latter type almost looks like a thick smartphone with touchscreen and other advanced features. These can be used to see the current settings or modify them depending on what vaping experience is desired. It’s possible to set a wallpaper, change the icons, and so on. You can also see the time, temperature, battery status, and system settings. Larger screens are nice as you can see more information but they also drain the battery faster.
Safety Features
See if the device has any safety features that will allow you to vape with confidence. These devices have gotten bad publicity because of explosions that were featured in the news. These may have been caused by using cheap parts, having poor quality control procedures, rough handling, extreme settings, and more. In order to prevent this, newer devices are equipped with self-monitoring circuitry that constantly checks for red flags. For example, they may turn the device off if it exceeds a certain temperature or cap parameters with an allowed range. They can also be shut down if turned on accidentally and left idle for a time period.
Flow Control
It may be possible to adjust the air flow, as well as the juice flow. This can come in handy if you are low on liquid but want to conserve the remaining amount that you have. This could extend the life of your tank until you get home and grab some refills. You could instead increase the flow of juice if you want to produce a lot of vapor and do some exhibitions or simply enjoy the fuller flavor.
Output Voltage and Wattage
Lastly, check the adjustment capabilities of the mod. It would be nice if it could let you adjust the output voltage and the wattage of the device. Voltage range is usually between 3V to 6V with changes coming in 0.1V increments. A higher voltage means faster heating time for the coil. You should be able to produce more vapor as well. As for watts, the range is generally between 3W to 15W. Adjustment is possible in 0.5W increments or so.
