Vaping Hardware: A Beginner’s Guide (Part Two)

Welcome back to the Hardware Beginner’s Vaping Guide! This three-part guide is designed to help vapers of all walks of life. Last week we went over the anatomy of an e-cig, various atomizers, and the difference between regulated and unregulated mods. This week we will examine ohms and resistance, sub-ohm vaping, and proper battery safety guidelines. Let us help you stay safe and get the most out of your vape experience!

There are many factors that play into your vaping experience. The wattage, voltage, and coil construction of your device determine the overall feel of your vapor.

Wattage is the power of the electrical current in your device. In vaping, higher watts means higher temperatures and a hotter vape. Voltage is the force of the electricity in your device, delivery from the battery. Ohms are a measure of electrical resistance. The flow of electricity is restricted by ohms of the coil, and limits the flow of electricity (converted to heat in your vape. The higher the ohms, the lower the heat.


Ohm’s law states that the current through a conductor between two points is directly proportional to the voltage across two points.

Knowing the best voltage for your atomizer’s ohm level is very important for vape safety. If your amps are too low for your voltage, you risk a dangerous battery short. Know the ohm level on your coil, and use safe batteries designed for vaping.

In vaping equipment, different resistances are designed for different wattages. Each coil has an ideal wattage/temperature for the best vaping experience and can usually be found directly on the coil itself.

*Extreme caution, pristine equipment, and a working knowledge of Ohm’s law should be exercised when vaping at low ohms. Use safe batteries designed for vaping, and known their limitations. Regulated vape hardware recommended for low ohms.



Vaping has seen some incredible innovations since it hit the global market. Small, low-power equipment has been replaced with big, powerful mods. As high-wattage has skyrocketed in popularity, higher ohm atomizers have fallen out of style. Sub-ohm vaping means using vape atomizers at an ohm level lower than 1 ohm. Sub-ohm vapers generally experience massive cloud production, more intense flavor, and a hotter inhale.

To accommodate the heightened power of mods with lower ohms, sub-ohm vapers tend to prefer low-nicotine e-liquid. Sub-ohm vaping produces more vapor, so smoother, high-VG e-liquids ensure a more pleasurable vape experience. With great power comes great responsibility; higher wattage means a bigger importance for battery safety.

Vape hardware is powered by electricity, and batteries are the source of that power. Some mods and electronic cigarettes have internal batteries, which are typically charged via USB cables. Other products rely on removable external batteries, which can be recharged outside of the mod.

Like any tool, an electronic cigarette should be used with extreme caution. Since vaping involved electricity, a vaper needs to have a healthy respect for battery safety. Neglecting battery safety can result in a dangerous situation.

→ Never carry your batteries in your pocket without a protective case.
→ Never let the discharge rate of your build be greater than the max discharge rating of your battery.
→ Use batteries designed for vaping and make sure they are compatible with your hardware.
→ Never use damaged, frayed, or questionable batteries while vaping.
→ Don’t let your vape hardware get too hot; if your equipment is uncomfortably hot to the touch, refrain from vaping.
→ Store your batteries in a moderate temperature, and away from excessive moisture. Never leave your batteries in a hot car.


Like any new hobby, you will need to experiment with different hardware before you find your ideal vape hardware setup. Do not be afraid to experiment, but always err on the side of caution. Stay safe, research as much as you can, and be sure to have fun. Your vaping journey has only begun!

Join us next week for Part 3 where we will explain the difference between mouth-to-lung vaping and straight-to-lung vaping. We will also break down the composition of e-liquid and how different components affect taste and “throat hits”.

  • J Holland says:

    Some one needs to post this! Thanx Mt baker!

  • zach says:

    Helpful article. Would like to hear more about battery safety. Seems hard to get reliable specs on many of the 18650 bats out there.

  • Robert says:

    Very helpful.info

  • Ken C says:

    This guide would have been very useful to me when I first started vaping.

  • evan says:

    voltage seems off

  • Paul says:

    Great info. People need to know the device they are using and how it works

  • Robert says:

    I keep reading this all over and over and its still confusing.lol

  • John says:

    This type of info is why I use your site for all my vape needs. Makes way more sense after reading this!

  • Bryan Miller says:

    great guide too few vapers I know look at me like I have three heads when I bring up ohms law… like do you want to blow your face off when you think you’re advanced enough for an unregulated mech mod.

  • Pat Havrilla says:

    Good understandable info!

  • Catherine B. says:

    Very helpful information! Mt. Baker rocks!

  • Vicki says:

    You all rock so helping to us that don’t know ohms and such. You are so knowledgeable. I will always get hardware from you. Thanks so much
