Like many things, most people are fine with “Stock Options”. Then there are those where “Stock” is not an option, and then everyone else in between. Some are naturals when it comes to building and modifying, while most others need time and practice. Most vapers reach a point at which they consider building coils for personal use. Some may already be considered “Advanced Vapers” with the knowledge and experience they have gained from vaping, while others will need to learn and practice some more.

Most people tend to become interested in building their own coils for a few reasons:

  1. High VG and sweetened e-liquids, ruin atomizer coils quickly, and pre-built coils are expensive. Building coils can dramatically reduce the cost of vaping.
  2. Building coils means one can build coils that are much larger than the pre-built coils for a sub-ohm tank. The greater a coil’s surface area is, the more vapour it can generate. Building coils means that the biggest vapour clouds and richest flavour that vaping can offer can be enjoyed.
  3. Building coils also means one can build smaller, higher resistance , flavor-driven coils that don’t require nearly as much juice or power as the larger coils. These coils also tend to be safer to use.
  4. Some people simply enjoy tinkering with gadgets. Coil building is a natural match for tinkerers.

What to keep in mind:

Ohm's Law.Always make sure coils are within a safe range of resistance. A coil that is 0.3ohms will push 14 amps at 60 watts. If two 0.3ohm coils are used together the overall resistance will be 0.15 ohms and will push 20 amps at 60 watts. This can be safe if the appropriate high-drain lithium ion batteries are used and the device used can handle the amp load. Most coils require 3.5V-4.2V to fire properly. Mesh can fire as low as 2.5V, while some exotic builds such as Claptons require as much as 5V. The wattage will vary based on the resistance of the coil to achieve the mentioned Voltages. Always use an Ohm’s Law Calculator if unsure.

A few Amp Limitation Examples:

    • 0.1 ohm @ 4.2 Volts = 42 Amps
    • 0.15 ohm @ 4.2 Volts = 28 Amps
    • 0.2 ohm @ 4.2 Volts = 21 Amps
    • 0.25 ohm @ 4.2 Volts = 16.8 Amps
    • 0.3 ohm @ 4.2 Volts = 14 Amps
    • 0.4 ohm @ 4.2 Volts = 10.5 Amps
    • 0.5 ohm @ 4.2 Volts = 8.4 Amps

A battery that can handle 20 amps of continuous discharge isusuallycapable of a 40 amp pulse(short-burst), but this isn’t always true. Always make sure the battery used can handle more than the continuous discharge rating if going beyond it. AHOT BATTERY is anUNSAFE BATTERY. When inserting batteries into a Device, always be sure they are orientated properly. Always use batteries that are protected and have no rips or tears in them.

 

ADVANCED DEVICES 

What Vaping Devices work with Rebuildable Atomizers?

When coils are built , they can be assembled within any safe resistance preferred. Since the power drawn from the battery can be adjusted by changing the wattage delivered to the coil, any device or mod that can support a screw-on tank or atomizer can theoretically work with a rebuildable atomizer. Most vaping product manufacturers today design their rebuildable atomizers with sub-ohm vaping in mind. A rebuildable atomizer designed for sub-ohm vaping will have a free, airy draw. A small coil in a large rebuildable atomizer with open airflow will probably lead to an unsatisfactory vaping experience. However, with a tighter airflow, a decent vaping experience can be achieved.

For a good experience with a rebuildable atomizers, a device or mod with the following is needed:

    • A removable tank(510 threaded connection)
    • Support for sub-ohm atomizer coils(10+ amp rating)
    • Adjustable wattage(not required, but ideal)
    • A batterycapable of supporting a high-amperage load(20+ amp continuous discharge)
    • Built-in safety features to protect from short circuits, unsafe currents and overheating

 

About Mechanical Mods...

A quick search on YouTube, will lead to no shortage of videos about vaping. Found in those videos are some people who post vaping content on YouTube using mechanical mods. As the name implies, a mechanical mod is a purely mechanical unregulated device; it’s nothing but a tube and a button. A mechanical mod has no electronic components, therefore has no safety features. Even if something about a vaping configuration is unsafe(shorted pin or coil etc...), a mechanical mod will always activate the battery to complete the circuit when the button is pressed. Even some of the most experienced vaping experts have injured themselves by using mechanical mods incorrectly.

Mechanical mods are often inexpensive, but otherwise they provide no real benefits over electronic mods with built-in safety features. If a mechanical mod is used, be responsible for your personal safety (as well as others) and take the time to read extensively about the safe usage of lithium-ion batteries, as well of what they are capable of when handled incorrectly.
