I guess I wasn't that clear. I want to put the evercool in a device the size of a cr123, like in the following configuration. endcap - batt - batt - evercool - atty - endcap. That is the electrical flow I want. Namely the device is a GG that I built. Before anyone gets upset, it is not exactly a gg, just the same functions with an "AVS" tank on it. I do not intend on selling it or producing it in mass, only for personal use.

You sure? I believe the Infinity s using a linear regulator.

It probobly is, I was confusing it with this post saying they might have "new" technology in the future with up to 97% efficiency. I just figured it was in the infinity, and with that kinda efficiency it had to be a switching regulator... but it was never confirmed, soo.. my bad for assuming, haha.

I just got done building my first evercool mod. A dual 18650 stuffed into a 4x2x1 project boxed top with a 5ml syringe modded CE2. All I can say is WOW!!! This thing vapes like a steam engine. The first set of batteries weren't fresh off the charger, but I ended up getting a solid 36 hours out of them. Vapor poduction never let up one bit. When the batteries hit their low limit, it just quit vaping. Very impressed with the performance. I'm a tool maker, and am currently trying to come up with something a little more attractive to put this in.

What? That's not what Mr. Dawin says happens.
... No heat fluctuations or sag like in a variable voltage mod.

... Tons of vapor and TH. A variable voltage only regulates voltage, amps are left to fluctuate wildly causing good hits and bad ones and as the batteries weaken the vapor is reduced.

:p:evil:

Sounds like just another theory to me. Let me know when Mr Darwin comes up with something that is factual.

hi jon,

i wonder how did you vape out of that 36hrs ? is it almost constant vaping or on/off ?

i can only get 1 full day with pretty much continuously vaping the whole day out of my 2 x 18650 .. just curious whether is it my battery or something else i'm doing wrong (apart from continuously sucking that thing to dry :p) . i only have one set of battery, so i cannot compare until i get another pair... :(

thx

owh sorry... i use carto 2.9 ohm, batt is trustfire 2400 (actual not sure.. but from review many says around 2200mah , i don't have any right knowledge to test it... and my measuring device is pathetic u don't want to know ) ... i keep topping up the whole day as and when required... although around 7-8 mg... i get quite a headache from nic overdose (i think) for the sake of trying to drain that battery

edit ... i'm at around 4.3-4.5V ( cheap analog meter :p)

Im running on 4.5v unloaded on the evercool with a C2 syringe mod (think its 2.8/9ohm) as well..i can easily get thru 10ml a day. The juice it saps is mad at higher then intended voltages but i love the vape - thick and tasty.

Don't worry about it, sounds about right to me. Two 18650's in series still have the same mAh as one and there is some loss, unlike a tube or box box mod.

Sorry for not getting back on soon enough. I had a brief stay in the hospital. Here's a pic of my ugly little box mod. I accidently broke the coil off of the PCB, but it still works well. It was a PITA trying to shoehorn everything in there. Once it was all together, it didn't work. Had to take it all apart to find that I had a bad solder joint giving me intermittent mis-fires. Out of the 36 hours of use, 7 of that was over night while sleeping, but the rest was a solid 29 hours of use, and approx. 6 ml of juice through the syringe mod. I don't get where Mr. Darwin says that amps would wildly fluctuate causing inconsistent vapes. I'm no electrical engineer, but isn't that the purpose of the caps? Anyway, my info comes through real world use and not theory. I run my set-up at 4.2-4.3 volts with a 3.1 ohm atty. Nice warm vapor with alot of flavor. Any higher voltage and I get a burnt taste with my juice. 4-5 toots at HV will just about fog a room out, but I just don't like the burnt taste. Also my batteries are fairly new, with less than 10 charge cycles on them, if that makes a difference. All in all, I'm really pleased with the performance. This is my go to mod now,(until I get something prettier built) and I'd like to thank everyone in thats participated in this thread. Great info here as always. Can't wait to build a genesis, and marry the 2 together. I'm thinking that, that will be the ultimate in vaping.

No, it has nothing to do with the caps. Most of the regulated mods folks build don't use caps, they still provide a consistent vape for the entire charge.

Regulators of all types/styles are used everywhere, they are made to maintain the set voltage.

I don't get where Mr. Darwin says...
Neither would anyone who has actually used a VV device.

Well said.

Personally, I wouldn't knock watt control if you haven't tried it, but that's me. Ask others, and there are many working on this "theory" OTHER than "Darwin", how consistent it can be......

Watts equals heat (period). Yeah a water heater (or a PV for that matter) will put out the same watts and NOT the same "heat" (over time) but that is typically due to ancillary components (that build up over time) or inconsistencies in the heating element - which voltage NOR watts (watt “rating” being at a constant) can compensate for - other than cranking it up or replacing the element(s), which we have the ease and convenience of doing do in the modder’s world :facepalm: ; you still have to adjust something to get the same heat.

What works better? Hmmmm? Either way, VV (of which I have many) or watt control (which I have 1 and second in prototype in the works) BOTH will suffer the same result when these ancillary components come into play - except one factor - one automatically adjusts the other doesn't -- Hmmmm? what might that be? Could it Perhaps be heat – the key element of a satisfying vape?

Which offers the best vape? You, the (diverse) vapor of both controls, can only know. I'd say, yes, it’s an "fairly" even call - VW≈ = VV - it all provides the same in the end (with adjustment - of -course) but does it do it in real time?. Not.... VW wins every time as it automatically adjusts. – Go figure

From that aspect, VV DOES NOT allow you to change atties of different resistances WITHOUT substantial measurement and calculation to know where you need or would like it to be nor does it compensate for the variations in resistance commonly experienced during the average vape - however minute OR extreme. To me watt control seems to take at least a little bit of the calculation out of the equation and provide a MUCH better vape over all as it is constantly changing and adjusting (again, however minute it may be) in REAL time.

Aside from all that, and in conclusion; The idea of incorporating vapor temperature monitor is fantastic. Otherwise, until Temp control comes into the equation, I feel VW and VV are Almost equal in ANY competition – but, to me, VW edges out if not wins hands down everytime .... :2c:

Sorry for derailing the current direction of the tread if I have done so , which (eh emmm) is far from the original…. we’re not talking Watt control are we now?

It seems interesting enough. In the end what we are truly looking for is the exact same temperature at the atty/carto each and every time. It doesn't really matter which path we take to get there, as long as we get there with some form of efficiency.

I'd be interested in building a VW mod, just to try it side by side with VV mod. Share a parts list and schematic, I'd be happy to replicate it, and give it a real world whirl.

Active temperature control, IMHO, is the key to "efficiency" jonboyusmc.

I would share my thoughts and schematics, but for now, all my design are proprietary, sorry. Too much thought and work involved - yet tomorrow, a new technology may come to play and we all may be on a "precipise" with newer ideas and better minds working on this so it may not matter. In the end, I think it best to hold back so as to not lead others "astray" untill I find it is the "best solution" -- but I'll think on it. Obvoiusly, a consortium of minds working on the solution would be more "efficient", I have not seen that direction in these forums....

So untill then, I will retire from posting further on this subject and in this thread "off topic"

Best regards,

McGyver

Untill then...
