You're not doing anything wrong if it's a loud crackling. That's the juice being vaporized. I used to think it was something I was doing wrong, but now I look for that sound as meaning my coil is clean and hot and doing its job. 
If it's an intermittent loud POP! then it might be an oversaturated coil. Nothing you're doing wrong, though.

Yep, probably nothing wrong. All vapes crackle and sizzle a bit as they cook up your juice, some more than others. Airflow sometimes makes a slight difference.
If it's a louder pop, loud enough that it's startling, that might mean a flooded wick. But yes, as said above, it's very normal.

vg/pg ratio can affect the sound; ambient conditions like humidity also seems to matter.
My top coil Kraken's do that using thinner juice. Thick juice won't wick up fast enough. Bottom coils don't have that problem and can use thicker juice and no popping.
My vapes pop from time to time if I turn down my power a bit it pops less --I think if the coil heats up a little slower
or does not heat up so high---a little less hot then the popping seems to subside.
You get all this heat all at once and the liquid and wick is at room temp ----just the "extreme hot" meeting the cold.
450 degrees in a half second meeting 70 degrees and it has to pop as the pressure has to dissipate slowly in order
to be silent.....but it can't exscape slowly---lower voltage/power--slower heat up time-- gives the pressure
created by "hot" meets "cold" a chance to exscape as it is being slowly created as compared to a "Big High Voltage Charge"
coming to the wick in a second.........just my observation from experience-------although this theory is not always
true--every time----it can be proved wrong as many theories can under certain circumstances.......

Not much you can do. In a RBA it might be too little wick in the coil. But with premade coils, that's the way they are. Turning down the power may help.
Thank you all for you advice. Its just I my wife is in the front room, and I pop into my "Vape" room, she can hear the loud pop! when I fire my cool fire up; after the initial loud pop, its ok and it only crackles. A great piece of kit. regards movictor1
OK, that loud pop initially is too much juice in the wick. I have a couple of tanks that do that, and I was mystified for a long time, but someone finally 'splained it to me, so now I expect it and it doesn't make me jump three feet when it happens anymore. Totally normal. It's just from sitting for a while, not being used.

If it's in the Innokin iSub family, that would explain it.
Nothing I have, I mean nothing, pops like the first fire of the day on my iSub tanks.
Even the heads I've rewicked.
No joke here... I hold the mod at arms length for that firing just so I don't give myself a heart attack.
Everyone remember those toy gun paper "snap caps"?
Yeah... like that.

ah, that sound is pretty normal when you vape, just think about when you cooking water to boil.. ecig is just the juice cooker on your hand, so if it's not a big terrific blow sound, just vape on.
OMG, ROFLMAO! That's EXACTLY what I did with mine, too! Hold it WAAAAAAY out there and hit the fire button until after it said, 'BANG!'
I have noticed, however, that since I started rewicking them with rayon, they don't pop like that. In fact, the iSub Gs don't seem to pop at all anymore on first use like they used to. I get a couple of "middling" type pops on my other sub-ohm tanks when I use them first thing in the morning, but those pops aren't bad, they're kind of "muffled" sounding. I wick those with rayon as well. Do you use cotton? I wonder if the wicking material has something to do with it? Hmmm... interesting thought...
~Lannie
I do use cotton, and while I did toss a small Rayon sampler in a cart not long ago, I don't think I'll be switching to it fulltime. But I may just redo an iSub head to see if I can reproduce your results. Science FTW!
I plan to at least try the RBA, but haven't brought the issue up in that thread here.
There's already a growing consensus that the wicking may be problematic, perhaps an update is in the works.
Either way... no one's mentioned the RBA popping... yet.

There's an RBA for the iSub? 
I hadn't heard! I need some o' those! Or were you talking about something else?
Victor, I'm so sorry! If you don't know, an "RBA" is "rebuildable atomizer." It means you can make your own coil and replace it when needed, instead of having to use the pre-made atomizers and coils. I don't mean to swerve your thread completely into the ditch, but that was news to me, and something I'm very interested in. Anyway, I just wanted to apologize for the small thead hijack and explain what we were talking about in case you were confused.

And a Clapton head, and Ni and Ti too. Even though when I asked, not that many weeks ago, Ash told me they weren't comfortable with either nickel or titanium wire.
Here's the RBA thread...
Innokin iSub RBA Kit!!!!
Oh, THANK YOU! Got it bookmarked and will order some ASAP. I'm not into temp control yet, but I have a couple mods that will do it, so maybe this will be my opportunity.
