Powerful but convenient...?

I am not familiar with any of the proper terms. I am currently using a Vision Spinner, ego twist and a Smoktech 1300. I am very frustrated with the issues I keep running into and I want something more powerful but like the innokin iTaste MVP 2 but convenient and compact like the Vision Spinner. I keep mine around my neck and have to frequently drop it down inside my shirt, while performing various tasks of my job. Is there a battery or mod that is powerful like the MVP 2 that is designed for attaching a lanyard onto and not too bulky for wearing around the neck and tucking under a shirt?

Have just got an eleaf istick and am very impressed with it. Not the best quality build but good enough for every day use. Very small and with a good capacity (2200mAh) battery built in. This thing is tiny, a full 30mm shorter than a 650mAh Evod VV.
It would be perfect for what you are looking for except... I don't know of any lanyards to fit it. :(

Just picked up an istick myself. 20 watts, small, compact, easy to read LED, very simple menu, 2200 mAh battery.

It is almost perfect. The main problem with it is it uses PWM and mean voltage calculations as opposed to RMS. This means it will vape hotter than what you're used to. For instance, if you set it to 10 watts, it will probably "feel" like 14-15 watts on another device. This caused Phil Busardo to give it a "thumbs down" even though he agreed there is a lot to like about it.

For me, it's not a deal breaker. I just turn up the wattage until I get a good mix of vapor and flavor and stop there. Hopefully in a future revision they will fix this RMS issue as well as add a spring loaded pin. If they do that, it will be the best device on the market for the price.

When I started using the iStick with my Kayfun I started winding an extra turn or two into my coils. I was at 1.4 to 1.7 ohms with the Provari and had to go back to 2 ohms with the iStick to be able to stay in the low range I vape at. With the lower resistance coils I was bottoming it out at 3v. I can comfortably vape at 3.5v and 3.7v with a 2 ohm coil. That's not really a problem.

This chart is interesting. It says the the iStick can't reduce below the voltage of the battery, so it will be hotter in the 3.7v range when the battery is fresh and will settle down as the battery goes below that. I guess it has a boost circuit, but no buck circuitry. The link to the chart below doesn't copy correctly but it's from ...................

Here's a post by Peraspera on the above chart he/she created.

I made a new chart showing what combinations of oHms/watts the iStick is capable of regulating. eLeaf/Joye U.S. confirmed with the manufacturer that the iStick does not have the capability to down regulate power.

The blue bars show what is fully regulated. The purple shows oHms/watts combos that are only regulated when the power level you have selected falls below the volts the battery is actually outputting. If the settings you have chosen are too low to be regulated the iStick screen shows values calculated from oHms law based on your chosen settings rather than showing the actual power coming from the battery that is going to the coil.

For example, if you are using a 1.8 oHm coil the iStick will fully regulated your vape between 10 and 16 watts. However, if you want to vape your 1.8 oHm coil at 7 watts you can not do so until the battery output falls below 3.6 volts. In practice, this would mean you would start vaping at 10 watts with a freshly charged battery with the temperature of the vape going lower until the battery was actually outputting below 3.6 volts. The iStick would then regulate your vape at 7 watts until the battery needed to be recharged. The screen will reflect 7 watts/3.5 volts irrespective what volts are actually being output to the coil.

Using the iStick in voltage mode doesn't change the fact that the iStick is not capable of reducing the power coming from the battery. If the battery is freshly charged, producing around 4.2 volts, and you have set the voltage to 3.8 the iStick will be delivering 4.2 volts, not 3.8 volts, to your coil.

The iStick will not allow you to select a power setting that requires more volts than is allowed in its regulated range. It will stop at the highest setting that the chip can regulate.

You can download the spreadsheet I used for the underlying data if you wish to look at it or modify it for another device. Choose File > Download as from inside the Google spreadsheet itself rather than your browser's menu. The colors on the spreadsheet are done with conditional formatting that matches spec limitations.

The data I used is from doing oHms law calculations. The device may produce something a bit different in actual use. So far, I haven't seen any reviews for the iStick using reliable electronic testing equipment to check its accuracy.

The short answer is that the voltage/wattage numbers for power displayed by the iStick are pretty much useless as far as determining how hot the vape will be compared to other devices. Adjust the iStick's power level to taste rather than using other device's power levels as a reference.

Adjusting to taste is pretty much what we all do anyway. I don't find the iStick ranging error due to the PWM implementation to be a problem at all. The Purist may scream that it's not Kosher, but it is what it is. We just expect RMS to be the standard because we are used to talking about voltage in RMS values.

The iStick probably should have had the menu choice to use AVG (MEAN) or RMS or a way to change it with a multiclick. I keep my Sigelei Zmax V3 on RMS because that makes it match my Provari's voltage scheme.

frak, to me vape is all about accessories and vape apparel. One can get tube and box holsters or lanyards for gear. Heck just bought a ScottEvest coat and light weight hoody. The coat easily holds 2 box mods in the outside hand pockets, and can put two mech mods in the lapel pockets, 18 or 26650 mechs :D plus hold my ipod, wallet, ebook, glasses, documents, batts, memory cards, camera.


frak me, we always found ways to bring a pack or two along. Lots of ways to securely vape on the goto.

Far as relatively compact power box mod, about the size of the hanaClone but thicker, really liking the Cloupor T6, single 26650 box. 14 amp max output, 9.3 volts, fits really nice in the hand, quick swap out of batt, and even usb chargeable. Doesn't have the balls of the T8, which I love too, but really liking it for single coil tanks.

But then, must say, me casual vape is 40-50 watts, sweet spot low 70's. So capable quality gear is a must. Heck, hands free, can comfortably carry 6 mods on me, all tanked and batts fresh, but generally only take 3 :D


Vape long and Prosper.!!!!

I use a couple of the Itaste vv V3's at work.. I call them my mini MVP's.
They are thin and fit in either my shirt pocket or the side pocket of my carhart pants.. They are easy to grab without snagging on the edge of the fabric..
I bring other mods there as well,but those are the ones that are on my person at all times if i have to leave my station at all..

I use the T3'D tanks on them and tug on them like hittin a stogy..
Nice and sleek like..:vapor:
