Question on coils!

[Cristian Vazquez]

Here I am again with another question! Looking into getting an RDA, been eyeing the Igo W as it's pretty cheap, 3 posts for dual coils, and the little holes to insert the legs! I'm already kinda familiar with the process of how to build them, but in my research, I've realized that there's 3 categories of coils. Normal wraps, Micro coils, and now even Nano Coils. My question is, what's the difference between the 3? Seems that Microcoils are better than normal wraps from what I've seen, but they're generally for sub-ohming, which I can't do cus my Vamo V5 has a 1.5 ohm limit. Would someone explain the differences, their pros and cons, and if they're viable to use with my Vamo V5? Thanks everyone!

Regular coils are spaced out. Micro coils are wrapped like a compressed spring, where they all touch. As far as I can tell nano coils are just a micro coil with a smaller inner diameter. I never use the term nano coils, as you can just say you're wrapping a micro around a paperclip or a needle. As far as I'm concerned nano coil is a redundant term. I personally wrap micro coils for everything. I think they just work better, regardless of what resistance you are shooting for, but they require good, fast wicking to be effective, IMO.

If you are using a PV, like the Vamo, you have the means of pushing watts by the flick of a button. Unlike with mech mods where you need to go sub ohm resistance to reach higher Watts as you can't regulate the battery voltage.
So as long as you use the Vamo don't worry about sub ohms.

Now the different type of coils more relate to the way you coil the resistance wire as explained already

You could use a thinner wire (higher resistance) to still make a tighter, small coil. You can also make a larger coil and just push the watts up on your vamo.

On my PV I often have a 4+ ohm coil, pushing 12-15 watt easily. If gives nice thick and rich vape as long as you can get it to wick sufficiently.

So you can play with your coils to any extend. Its not needed to go sub ohm on a PV though.

Thanks for your answers you two. You wouldn't have access to a sort of tutorial would you? Somethinf extremely noob friendly that explains the "why"s too. For example, everyone on the videos I've seen says "make sure your coil isn't touching the posts or anything around it" but don't explain the reason why, which is that it'll make the thing short. Just thought I'd ask

If your coil is touching any part of the base it will create a short. Overlapping coils will do the same.

There are many tutorials on YouTube regarding building different types of coils. The inner diameter of the coil determines the type of coil it is.

Nano coil - <1.4 mm in diameter
Micro coil - 1.4-1.65 mm in diameter
standard coil - >1.65 mm in diameter

If you don't have an ohm reader consider getting one. It's important to know the ohms of your build (and whether or not you have a short) before firing it on your mod. Plus, it makes a handy base to build on.

If your looking for a tutorial on each coil type go to you tube. They have wondetful step by step how to videos
. You would look up for a example, how to make a micro coil, or how to make a nano coil. Your will find several well put together, step by step how to videos. Hope this helps.

If you are wrapping coils and attaching them to an RBA, the coil needs to be centered over the air hole for more flavor and vapor. Side holes generally force you to have longer legs and a right angle bend at the top to center the coil over the air hole. There's a greater chance that a short will occur when you have to do that.

Nano coil - <1.4 mm in diameter
Micro coil - 1.4-1.65 mm in diameter
standard coil - >1.65 mm in diameter

For more information on coil types, go here (ECF thread). Post #7 has the above list in that thread.

Some of the best videos I have watched on you tube were done by rip trippers. Just search "rip trippers" on you tube and you should get a lot of information.

I honestly think any reference to micro coil having anything to do with inner diameter is just caused by misunderstanding, and the pointless nano term grew out of it. Since they were invented, micro coil has been a reference to the space between the coils, not the diameter. Oh well, as per the post linked above, somebody has done gone and made a chart based on their opinion, and now it will never go away.

The suggestion to watch RipTrippers vids is spot on, and he is very entertaining to watch.

Some great info in this short thread which I will put to good use when I build my first coils.

You can wind just about any size coil you want if cotton is your wicking medium. You make the cotton in the diameter needed. With silica rope, you have to wind the coil to match the diameter of the rope. When I use silica, it's 2mm, which results in a standard sized coil.

Smaller coils let you wind more turns for the same resistance and that can give you a longer contact point with the wick. Smaller Kanthal wire like 32ga lets you reach a given resistance point with fewer turns and the smaller wire heats more quickly. Larger 28ga wire lets you use longer lengths and longer coils since larger wire is less resistive, letting you wind more turns for the same resistance.

The down side of larger wire is the second or two it takes to reach atomization temperature. With 26ga I find myself pressing the fire button and waiting a second or two before vaping to give the coil time to start sizzling. If you hold the drip tip to your ear and note the lag time, you can hear the coil start to sizzle at different points with larger and smaller wire in the coils. 32ga is quick. 26ga takes a second or more to start sizzling. Of course, you can control that with voltage changes.
