You should start by knowing what you want in the vape. Meaning that you should determine the purpose of the pen with what you will be vaping. Like you should know whether you will be vaping e-juice, dry herbs or wax vape. By doing this you will be in a better position to purchase the right pencil being that each pen has its specific product. A good example is a person who will vape all the three products as there is a pen that is three in one and it can be used with all the products.
Also, you should consider the size and capacity of the battery. You should know that battery life is very essential and it does not matter the type of pen you want to buy. It is essential to note that larger batteries are the best since they produce more power and go for an extended period. It is also essential to note that the portability of the battery is also essential as this will determine the places that you will be able to carry your vape pen with you. For that matter, it is always recommended that you choose smaller batteries over large ones for the purpose of portability and usability, but you can still choose the large ones depending on your preferences.
In addition, it is also required that you consider variable voltage over variable temperature. One good thing with this is that it will allow you to choose settings that uniforms your preferences even though most of them do operate at fixed temperature and voltage. In this case, it is recommended that you look for a vape pen that will provide you with as many options as possible.
In addition, you should also consider the size of the tank. It is essential to note that with a big tank you will not need to fill the pen all the time making you enjoy vaping for long. I understand that most of the vape pens are not that large, but at least you should go for the one with maximum capacity. In case, you cannot see where the capacity is indicated, and it can be better if you inquire with the dealer to prevent you from buying the wrong vape pen.
In addition, you should also ask around from some of your friends on the best vape pens. One good thing with this method is that you will be in a position to get the best vape pen being that you can see how best they are enjoying it.
Lastly, you should check their rates. The best thing that you can do is to buy a quality vape pen that is offered at reasonable prices.
