Exposed wick clearomizers vs. not exposed

[PrettyLord]

Hi new forum people, I'm pretty new to vaping, got into it about a month ago. Currently working with a VOT Variable volt eGo passthrough battery, and an ismoka bcc mega tank with the 2.4 ohm coil in it (I already used and disposed of the 1.8 and 2.2).

Couple questions though, what's better an exposed wick clearomizer or unexposed. I've had two different tanks, both bottom coil unexposed wick clearomizers, and with both after a little bit I start to get a really burnt taste and it's just really harsh and unenjoyable. Is this because the wicks aren't absorbing the liquid properly or what?

I'm generally new to vaping in general so any help is greatly appreciated, also, what are these crazy as .... mods I see people talking about, and what's the difference between them and a normal battery?

usually if there is plenty of liquid in the tank to saturate the wicks but your getting a burnt taste its one of two things. either too much voltage being applied for the ohm causing it to run too hot, or your using a liquid that would be too high in vg content. vg is the thickest part of the liquid and can slow down the wicks ability to get the juice to the coil if the content is too high for that system.

hope this helps you

I usually keep it around 4.6, is that too much for a 2.4 ohm clearomizer? also the liquid is 50/50 pg/vg

Definitely. On a 2.4 ohm clearo, 3.7 volts is middle of the road and produces a good vape. Go as low as 3.2 for a softer vape, higher than 4.2 starts burning. You're half a volt above that. Besides the burnt taste, you're shortening the life of your coil.

Here's a basic primer and vaping power chart to help you select the correct voltage for the resistance of your coil to produce the best vape. Vaping Power Chart for Variable Voltage E-Cigarette Batteries

With Power chart, it seem that you go too high, you should go around 3.7 to 4.0V, beside with bottom coil, sometime you must draw some puffs without activate the power button, with this action you can let the fresh juice easily to be absorbed. If you do not do it, the vaccum inside the tube make juice hardly to be absorbed by the wick.

sorry because my bad English.

Turned down my voltage to 3.8, tasting a lot better, also doing the dry draw thing, don't know which is helping more tbh.

But what do you guys think about the exposed wick vs non exposed? is there a such thing as bottom coil w/ exposed wick?

 

[Nermal]

I've never seen a bottom coil with what you call an exposed. I suspect that a wick used on a top coil would cause some flooding, while the wicks used on bottom coils would cause lots of burning and dry hits if used on a top coil.

What you are calling exposed is a top coil. They have the long wicks that hang into the liquid. This is done so that liquid can wick upwards to the coil when the tank level goes down. The "unexposed" you are referring to is a bottom coil. It's not really unexposed, it just has a really short wick that sticks out a couple millimeters from the coil head. It doesn't need to be long because it's down in the liquid all the time.

Bottom coils (unexposed) use gravity to feed the coil and (exposed) "top coils" juice is drawn against gravity to the coil. Hope this helps.

And voltage around 4

 

[PrettyLord]

Oh yeah, that makes perfect sense.

Now that that's established do any of you guys have preferences towards bottom coils or top?

 

[dangkhoa02106]

I use bottom coil only for bold and charm flavors such as coffee, Cohiba, Cuban etc..., with fruit or candy flavors I use top coil.
bottom coil: cool vapor, hard to draw (you must do a deep and long draw), less throat hit, do not need to tilt your device but easily get burnt-taste. My Protank, T3 easily burnt and damage the wick after a few tanks and it also have dark soot inside the air tube (maybe I use dark and thick juice), very economic to rebuilt.
top coil: warm vapor, more throat hit, easily to draw, must tilt your device, but it easily flooding,

Both have pros and cons.

One of my favorites is the old reliable T2 top coil. It tends to be a warmer vape because the coil is closer to the mouthpiece. However you have to constantly do a little swirly dance to keep the wicks wet, especially when the juice level gets low. IMHO it is also easier to fill because it fills from the top, and can be topped off while still on the battery.

I also use the Evod which is a little cooler, but rather flawless. The tiny bottom wicks almost never dry out, and it can use heavier vg juice better. It's a little harder to fill from the bottom...also IMHO.

There are of course many variations and everyone has their sentimental favorites (and will defend them to the death). Other than the Evod, I find most bottom coil types to be rather airy.

I love my Davide (PT2-ish clone) for my bottom coil.
My favorite top-coil and my daily driver is a Vivi Nova. There's just something I like about the top coil tanks.
Happy Vaping.
