Riddle me this

[Durpiedurp]

Because I honestly don't know. I've been vaping happily for a couple of years now on my original Erlkonigin. Started out on a Nemesis mech mod, ended up on a Evic VTC Mini. I use a 1.5 ohms coil (Kanthal A1) in this singlecoil badboy on round and about 8 watts. And it works like a charm.

I have been doing some sidesteps to dual coil RTA's but they weren't my thing it turned out. And as spares have been getting harder to obtain I have been looking for a good replacement. Requirements;

- Top fill
- Reasonable ml capacity (4+ml is huge these days, I unfortunately found out)
- Easily buildable

Whilst there are some pretty neat devices out there (and my eye is set on the EHPro Bachelor), I noticed that they all seem to be running 0.3 ohm coils on 30 or so watts.... Which strikes me as insane compared to the 1.5 ohms / 8 watts I'm used to. If I were to use 30 watts on my Erl, even with a 1.5 ohm coil, I would instafry the coil.

How is it that new single coil devices all require what appears to be insane amounts of power against insanely low resistances? And would a device like the Bachelor even perform on a 1.5 ohm coil with 8 watts of power or am I just talking crazy talk now?

I honestly want to know why older RTA's can't handle the power newer devices can't seem to work without. Anyone out there who could clarify this for me?

The lower the resistance, the more wattage that is required to achieve the same voltage - it's just a basic principle (law) of electricity. 30 watts at ~.3 ohms is somewhere in the neighborhood of about 3 volts - actually pretty tame by a lot of standards. Your 8 watts against 1.5 ohms actually draws more voltage - ~3.4.

It sounds to me like you're more of a single coil, higher resistance (possibly mouth-to-lung) type of vaper. Have you considered a Kayfun?

Most of the low resistance/high wattage stuff has a lot of air flow, just something to consider if you prefer mtl.

Sounds to me like Kayfun5 might be what you're looking for. I prefer the KF4, but that's only because I use them in long-Mode (which holds ~6.5ml's of liquid).
If you decide you want one, and can't find one, let me know. I have a brand new one I've never opened. Of course, I'll post here in the classies and do it the right way.

"high power" tanks have larger airflow and more efficient wicking. Some will do okay with less power, but many would leak. You can't run an older MTL tank at high power because the wicking and air won't be able to keep up.

 

[Zakillah]

Yeah, all that plus building space. Those higher power tanks fit larger coils that just need more power to get going.

I suggest getting a Kayfun. The V4 has allot of parts and takes a minute to figure out how it all works but its works well and has great flavor. The V3 mini is easier to use, still has the great Kayfun flavor but is very small and only holds 2ml, but it has top fill so no biggie to filler back up. The Kayfun 5 which has become my all day vape is super easy to use, has a easy to use build deck and topfill.

The V5 is probably the best bet right now.

The erlkonigin is a great tank, I have 5 and love them. Unless your looking to start vaping over 30 watts, there still is nothing much better then what you have now. But vaping the same tank gets old , so I understand something new. As mentioned already, the kayfun mini v3 is awesome! Great tank but is only 2mls. I personally love small tanks, all my erlkonigin's are mini tanks, so the km3 is comparable. One thing though, not that it matters, is that the erlkonigin can handle about 30 watts. I vape all of mine between 23 to 27 watts with no problems at all. Again mentioned above is the k5, also a great tank. Good luck

That is not entirely true. It all comes down to the size of the wire. A thicker lower guage wire simply needs more power. Thicker wires DO have lower resistances than the same length of thinner wire. But resistance isn't the factor, resistance is completely relative just like the voltage. It has to do with the size of the wire. For example, 30 gauge ni200 has extremely low resistance, but does not need significant wattage to heat up quickly.

Think of wire as a highway. To fill an 8 lane highway, it takes more cars compared to filling a 4 lane highway.

Exactly! Resistance in itself means nothing, coil mass people, coil mass.

Remember also that the vape game has changed since the Erl and Rose 2 were all the rage. Regulated mods these days are capable of firing pretty much any kind of coil you like, whereas 'back in the day' such power was only available using mech mod and an atty with an open build deck (RDA) that could fit large coils and thick wire. Nowadays the same vape can be had with long, thin-wire coils that can fit into tanks and be fired with enough power to mimic a dripper. This is also partly thanks to the fact that modders are continually improving the basic design of RTAs - maximizing their potential and performance in a system that demands a high level of precision.

My obsession right now is for single coil RTAs with a draw suitable for RLH. I'm looking for flavor above all else but I'd rather rip than sip. I tend to think of this market segment as the evolution of the same market that attracted users to the Erl and other similarly targeted atties (Rose, Calix, Squape, etc ...). Originally these RTAs were built for silica and modest power which suited the materials and mods standard at the time. Today their counterparts have followed the vape trend and are designed primarily for cotton and are capable of vaping at much higher power. To further illustrate my point we now see some RTAs doing away with the standard adjustable center pin and moving back to a fixed center pin that is more suitable for TC builds.

There are still a lot of options out there that fit your current vape style (and hey, if it ain't broke ...). There is also a lot of gear designed for RLH that also works very well with MTL. You might like to check out this monster of a thread that's all about tootie puffin'.

The only tank I own that ticks your three boxes of top fill, easy to build, and 4ml+ capacity is the Rose v3. The Mark Bugs Gem comes close but the for the fiddly build (having to dig out a proprietary build tool [read: dry fire ring] is a PITA). But top-fill is not my thing so I have a very limited sample pool.

Good luck with your search!
