Tutorial: Ohms Law and Vape Safety Calculator
Overview of Ohms Law and Vape Safety
Mechanical mods, high wattage regulated mods, rebuild-able dripping atomizers and rebuild-able tank atomizers are becoming extremely popular. Most experienced vapers quickly realize the cost savings of rebuilding and make simple RDA's / RBA's and RTA's part of their daily life. It's no surprise - for the cost of a pack of coils you could buy a year supply of kanthal wire and organic cotton - the building blocks of most vape coils built today. Additionally, self build coils in RDA's tend to produce a lot more vapor and superb flavor over traditional coils, but this post is not about that.
This post is about vaping safely and what that means. Let's face it, a metal tube with a high voltage battery or a high wattage (think 150W) box mod with two is nothing to smirk at. You are putting that thing right next to your eyes, mouth and face and firing (activating) it. You WANT to be safe! Before building your first coil, it is highly recommended to buy an ohms meter. This is a device that will tell you the resistance of the coils on your atomizer. Armed with resistance (Ω) you will be able to easily figure out if your setup is safe. But first, what exactly is "safety" when it comes to mods and e-cigs? Easy, the batteries used today for most mechanical and box mods are either 18650 or 26650 series batteries. These batteries vary in Amps - amps are batteries' ability to discharge stored energy (current). When a battery is pushed above its limits, the battery can vent, which means hot chemicals exit the battery under very high pressure or the battery could blow up. Yep. It's as scary as it sounds. That's why you should never push a battery beyond its capability. You should always check the resistance of your coil and calculate the amps the coil will pull from the battery, using either the volts for mechanical mods (4.2 for most 18650 and 26650 batteries) or watts you will set your box mod to. Sub-Ohming is easy and can be done safely, as long as you follow the simple guidelines above. For those of us not in favor of doing the math on our own, we built a handy Ohms Law Calculator in our signature easy to understand style. Notice, each variable is color coded to represent a piece on the mod below.

To use the Ohms Law Calculator to ensure vape safety, enter any two variables in their respective boxes and hit calculate. If the AMPS value comes out higher than what your battery is rated for, adjust either Ohms on your coil build or wattage output on your box mod.
Enter any two variables
For the mathematically and scientifically gifted out there, Ohm's Law defines the relationship between power, voltage, current, and resistance. The various possible formulas for Ohm's law are as follows.
