Regular coils v mesh coils – which would best suit you?
You now have a wonderful array of electronic cigarettes to choose from. While vaping equipment varies in performance, all e-cigs basically work the same way. Each features a battery, a reservoir of e liquid and an atomiser head. That atomiser head incorporates a heating coil. When you fire the battery, the coil heats up and vaporizes the eliquid. The vapour travels up the chimney and you can inhale it. Simples!
Your coils will dictate the nature of your vaping experience. They can be fashioned from a variety of materials and boast different resistances.
Some coils aren’t even coils at all because they are mesh!
What is a vape coil?
A regular vape coil is a length of wire wrapped in a spiral shape around wicking material. It fits into the atomiser head and connects the positive terminal of the battery to the negative. Some atomiser heads feature a single coil, others multiple coils. You will see dual, triple and quadruple coil configurations.
Multiple coils deliver more intense flavour and bigger clouds but will drain both your battery and e liquid quicker than a single coil. The resistance of your coils will also dictate the rate at which your battery charge and e liquid are consumed.
What is coil resistance?
Coil resistance is expressed in ohms. The lower the resistance of a coil, the more current can flow through the circuit. The means that the lower the resistance of your coils, the hotter they will get, and the more e-liquid will be vaporized. Coils with resistances of less than one ohm are referred to as sub-ohm.
Sub-ohm coils deliver voluminous vapour and warmer vapour. They may also offer a greater intensity of flavour. But these coils will drain your battery quickly and could shorten its life. Sub-ohm coils don’t last as long as coils with higher resistances. You will also be more likely to experience dry hits when vaping with sub-ohm coils.
What are coil wires made of?
Single or multiple coils may be fashioned from one of five different materials. Those with higher resistances which are designed for mouth to lung vaping are generally made from kanthal or NiChrome. The latter heats faster and both can be used only for vaping in wattage modes.
Titanium coils are suitable for temperature control (TC) and wattage modes. The titanium heats and cools very quickly for enhanced flavour. Stainless steel also heats and cools quickly, it lasts longer than titanium and can be used in both TC and wattage modes. Ni200 (Nickel) has almost zero resistance to electrical current, ensuring that it heats faster than any other material. It can only be used for TC mode because it might otherwise overheat and some vapers will have an allergic reaction to the nickel.
What are mesh coils?
Many believe that surface area is the Holy Grail of coils. This is one reason why some atomisers feature multiple coils. Manufacturers have been striving to achieve greater heating areas, and the result of their efforts has been the creation of mesh coils. Rather than featuring a wire wrapped around the wicking material, these coils boast small mesh sheets. In other words, metal with holes punched in it encircles the wicking material.
The advantages of mesh coils
Faster ramp up time (the time which it takes your coil to heat up)
More intense flavour
Even heat distribution for consistent vapes
Longer lifespans (the even heating prevents heat accumulation in one place and therefore reduces the incidence of burnt coils)
Purer flavour (flavour quality is subjective but some vapers insist that mesh coils provide purer flavour)
Reduced power (you need less power to deliver optimum performance)
The disadvantages of mesh coils
Increased e liquid consumption
Work better with some flavours than with others
Are mesh coils for you?
As mesh coils last longer, give you impressive vapour and may improve flavour, they are well worth trying. Mesh coils are now available for many devices, giving you the chance to test them out with your existing equipment. The cost of the additional e-liquid consumption will be offset by the fact that you shouldn’t need to replace your coils so frequently.
Mesh coils aren’t for everyone and there’s only one way to find out if they suit you!
