Why Do Sub Ohm Take So Much Voltage?

I haven't seen this discussed yet, so I figured I'd announce my discovery:

I use a Kanger EVOD single coil tank, and a non variable voltage eGo style Kanger battery.

When I vape PG, it tastes like a grandma ultra light if I don't use a 1.8ohm coil.

But these 1.8ohm coils burn out instantaneously if I put VG in.

To vape the thicker VG, the 2.5ohm coils work wonderfully.  

Im new to external battery mods but have been vaping for 3 years and I know how to prime a coil with e-juice. I go the extra mile after I prime the coil and let it sit for a minute. Then I fill up the tank put it back together and do not touch it for at least an hour or two just to make sure. I just got my now verified as legit sigelei sobra with the moonshot 120 both of the coils from that taste like those knock off BS eBay fake coils. I started off at a very low wattage and I don't know what's wrong both coils are disgusting. It's not exactly a burnt taste or a dry taste it's like a sour off taste and I can't use them. It also makes me feel like I have something in the back of my throat. What in the heck is going on? Do these coils take awhile to become usable? They're the coils that came with the mod and I verified the mod so I assume the coils are also okay. I even went so far as to try the second coil on a different mod but with the same tank just in case the mod was frying things the very first hit. Can anyone give me an idea of what's going on so I know what I need to do and also if anyone could tell me whether or not the Cascade baby coils will fit in the moonshot 120  

I've always wondered whats better for efficiency. In a regulated mod I can't imagine it really makes a difference in vape performance, I'm currently keeping my builds at a lower resistance by winding parallel coils. My goto build comes to about 0.4ohms and I run it in the range of 28-38w, usually set at 32w, if I wound it in series it would be around 1.6ohm which would need about 7v to get to 30w and at my Aegis solos max voltage of 8v would provide 40w. The only issue with this is that it limits the wattage range you can run at, since I sometimes do crank this build upto 42w, although it does start to burn above 45w.

The one advantage of running at a high voltage and a lower current is that theoretically there should be less energy loss in the transmission of power to the coils (like in the pin, the posts and the wiring connecting the 510), although depending on the construction of the mod/tank it may not be significant enough to provide any benifit. I can imagine that it's not that simple either as the mod is having to boost the voltage more which may cause the voltage conversion efficiency to suffer. Although in my dual cell mod it may be benificial since the input voltage is around 6.4-8.4v, although I tend to use this for my higher wattage builds.

This may just be me because I'm obsessed about how much voltage is dropped across cables, I always use the high quality wiring and keep it as short as possible because it is actually quite surprising how much energy you can loose through a cheap cable. Even good quality wire at higher amps can drop a significant amount of power.  

Hello just received new spinner 2 battery. I think I am burning my coil now it taste burnt. I have used spinner 2 for years no problems. This new version has more power has anyone experienced same issue. Do we just lower the voltage ? Or are better tanks needed or different
ohm coils? Thank you in advance for any help or opinions  

I'm having trouble with my Jem Pen E cig - hopefully someone can help me.

I take the coil out clean the tank and battery area, put it back in with liquid + prime the coil. for about 5 minutes it tastes fine and is vaping as normal. then a really horrible burnt taste comes in which is unbearable to smoke and making my throat hurt.

I take the coil out and clean again, put more liquid. the same thing happens! it tastes absolutely fine again and then gets burnt.
any idea why this is happening ? the device gets quite hot too...
i don't think the coil is the issue because why does it taste fine for a few mins?
I've ordered new coils so going to try that but worried its the device. i've only had it for 2 weeks and changed the coil about 5 days ago.  

I've got one that has me puzzled. I went through two fills of my Aerotank V2 with Cosmic Fog's Milk and Honey when it started to taste burnt. I figured no big deal, let me change the coil and clean the tank and all will be well. Well, new coil and cleaned tank and about 4 drags in it tastes burnt again. Thinking maybe I have a bum coil I try another one. Same deal.
I'm at a loss. It's the same bottle of liquid, same tank (cleaned each time), same battery (iStick 50w), same wattage (8.9), same resistance (1.2 ohm). Anyone have any clue what's could be causing this? It's getting expensive in coils and liquid!

Thanks  

My first .5 OCC coil only lasted 3 days . I put my device up to 25 watts and it totally fried it. A terrible burnt hit. I backed it back down to 20 watts and it was fine for a little while, but then another bad burnt hit. Down to 15 watts and I literally sucked hot particles in my mouth when taking a hit. ...? The cotton and/or coils are literally breaking apart? That's totally gross and I can only imagine, not that safe.

My second .5 OCC, I never put my device above 17 watts, keeping it at 15 watts for the most part. Within 4 days, same thing ... total burnt hit one day, sucking up hot particles the next?

What's going on? I thought I was supposed to be able to hit a .5 coil up to 30 watts ... Is sucking up hot particles from the coil normal? Should I just keep it at 12 to 15 watts and that's it, taking 1 to 2 second drags and that's it? Is it just a string of bad coils?

Thanks

EDIT: Thought I should mention that the juice I used for both coils was 50/50 watermelon. I hear it's better to use higher VG liquids with sub ohm tanks. But can that be part of the reason why the coils are being fried so quickly?  

I just bought new 1,2 ohm replacement coils to replace the original 1.5 ohm coils in my protank 3 / i-stick 50w. I also changed to new e-juice (cherry 50/50 18mg from smoktech). Now it pops really bad when set at 3,7 volts, where it was set previously using mt baker strawberry / bannana 50/50 18mg. It even pops some at lower voltage settings down to ~ 2.8 volts, but I don't get a very strong vape at that setting. Is this because of the different juice or because of the lower ohm coil? Is this the sound of my wick getting fried or what? If so, what is the solution to stop the popping while also get a strong vape?  

Hello,
Does anyone know why with the original Subtank mini the coils that came with it were
a .05 ohm coil and a 1.2 ohm coil i have noticed with the new subtank it comes with a .05 ohm coil and instead of the 1.2 ohm coil it comes with a 1.5 ohm coil
does anyone know the reason for this
thank you  

Hello guys,
I recently purchased a single coil RTA, my first rebuildable experience. I love it!! .
I saw at the shop a double coil RTA and a Double coil RDA, was planning on buying one of them until I thought I only have a 100W mod. Do you guys think it is enough? Are there some specific ohms coils that could make it work etc? Or is a 100W enough? I am new to this so calculating ohms law and all the other stuff I will learn, I just need a answer from the double coilers if you guys use higher wattage mods or not.
Thank you in advance!
