Dangerous Voltage For 1.6ohm Coil?

If I take softer but longer puffs will I consume less ejuice than I would if I take harder but shorter puffs? Also, how much of a difference does the amount of volts affect the amount of ejuice used?
I use an ego battery and have 4 air flow options, I like using 4.2V (my coil is 1.8Ohms) and the max airflow but this is not only tearing a hole in my wallet its practically making it disappear.
I only need enough volts required to vaporize the nicotine that I want (I'm not sure but I believe I'm using 46MG/10Ml nicotine ejuice, if I upgrade to higher level nicotine ejuice containers will the power and/or airflow requirements go down?
Finally, if I start using the 1.6Ohm coil (the only other coil the Nautilus is compatible with as far as I know.) will that make a difference in power consumption required to get the same effect?  

I have my Aspire Nautilus on my iTaste MVP 2.0 at 11 watts, running a 1.6ohm coil. I have also used it on my Nemesis mech mod with either an LG HE2 or a Sony VTC5 (I already know that mech's aren't ideal for tanks, but it was working really great). Everything has been fine, but now I'm noticing a bit of gurgling. Am I just under-powering the coil?  

So I purchased the eGo One after hearing amazing reviews of the device. I use an Aspire Atlantis on an MVP 3 but needed something more portable for work/going out. I was more than impressed with the eGo One using the .5 ohm coil, and equally so with the 1 ohm coil. The battery life is great, the flavour is perfect and the vapor production is unexpected. However, within 2 hours of using the .5ohm coil, the vapor began to taste burnt, more than on any other wick I have burnt. So until I could get hold of another I used the 1 ohm coil. 24 hours that one lasted. Joyetech said they would send me replacements free of charge, but while waiting for this I went to my local shop and bought another .5 coil. 1 HOUR LATER, it's frazzled. Wether I'm just being unlucky or the device is faulty I don't know, but I am incredibly disappointed. It's not through a lack of priming or using the wrong liquid, I'm an experienced vaper and had fully primed the wicks for 20minutes minimum and was using a 50/50 juice. This device had great potential, but it will be going in the bin for now (except the battery, which even does a great job on my Atlantis)  

I have a battery that is capable of going up to 6.0 V but the chart that came with the battery did not have 1.6 Ohm listed on the chart, it skipped from 1.5 Ohm to 1.8 Ohm.
I just need to know what the max amount of volts that I can use with this coil without reducing it's life expectancy to much.

- Also is there any reason to prefer variable wattage mode over variable voltage? because I always use V/V mode never even tried V/W.  

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  

okay, so i had a problem yesterday where i would keep getting juice popping up on the draw, that problem is solved, however, now on only the second day of light use, on the 1.2 ohm coil that came with the tank i am getting a pretty harsh smokey taste. Its not overwhelming like it is when a coil is burnt out, just an unpleasant taste. I did 4 drops of liquid on the coil before using, everything is screwed in tight. Do i need maybe a couple more drops on the coil?

FYI: using an istick 30w burning at about 14.5-15w  

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.  

Hey guys,
I recently started playing around with 24g kanthal in a kayfun lite plus clone that I had bought last year and started to notice a serious issue which was that juice would at some point start to look orangish, when I recently opened it up to change the coil to put in a new flavor it was completely black. However when I had previously fired it and had noticed no burnt taste. Any ideas as to what's going on.

Hi I am a new user to vaping I want to know if the coil is burnt beacuse it seems black inside. Is it possible to know seeing outside if it is burnt? the coil is 0.5 ohm euc (veco tank) and the taste seems to be nothing ...  

Hello vapers! first! I'm a noob at this stuff because I just buy my tank and use it with the coils it comes with and second, my english isnt that good but I can understand it perfectly fine.

Anyway, Ive been searching everywhere but I couldnt find a solid answer to my question.
Im using an Aerotank Giant right now with a 1.8 ohm coil, if I put a 1.2 ohm I would have to use less voltage because I get a burnt taste and the coil burns pretty quick, Im about to order a Sub ohm tank soon and I'll use the stock coils, the one im getting is the Kangertech SubOhm tank.
Why do subohm coils use more voltage when normal coils use less?

I mean, Ive seen people do things like 0.2 ohm coil @ 100W + If I did anything over 3.5V on my 1.2 ohm coil itd burn instantly... SubOhm takes more voltage the lower you go and normal dual coils take less voltage the lower you go!

1.9 Ohm Dual coil = 3.7-3.8V for me
0.5 ohm OOC subtank sub ohm coil = 12-30W?!

Thanks in advance for taking the time to reply to this post and your patience!

Cheers!

Edit: by the way, Im planning to use my subtank with a 50/50 PG/VG 16mg nicotine, Is that ok?
