They actually did a VERY good job with the design and quality of the iStick.

They just missed the boat with the "Leaf Volts"...

;)

(Thanks Kodiak, I LOVE that term)


The boat!???? Heck, they didn't even get to the dock because of this Vavg design. lol
+1 on liking the "Leaf Volts" term

I just got my Istick last night and love the form factor and design layout but this "Leaf Volts" thing is crazy off the mark. At least with the unit I got the volt difference seems to be running much higher than just 1 volt. I knew about this issue so I made sure to set it as low as possible (3v) before I connected my D14 Genesis which I have coiled up @ 1.7 ohms and have used this same set-up for over a year on my Provari set at 4.4v. This little Istick toasted my coil to the wick instantly. After messing with my coil for about 30 minutes to no avail, I switched over to my KFL which has a 1.5 ohm coil which I have used for 9+ months with this set-up and have always run it on my Provari at about 4.2v. It's usable for right now but I have to take short hits to prevent the cotton from frying. I'll be making new higher ohm coils tonight for both the D14 Genny as well as my KFL so I can at least use and hopefully enjoy this little Istick. But damn... What were they thinking? Everything else about this device is nearly perfect and they really nailed it with this thing but they have got to correct this major screw-up. And yes, this is a major screw-up IMHO.

I'm hoping that my mini naughty with 1.8 BVC's shows up in the mail soon. It sounds like folks have had good luck with this combination. Small, leak proof and long bat life is what my ultimate goal is. I hope this set-up fills this need.
Come on USPS. :D

Help !!!!

I think I have at some point cross threaded one of my tanks on my istick now nothing will screw in to it, I guess I have stripped the threading on the 510 connector.

What do you guys think? can the 510 be replaced if you have some knowledge of soldering ????

Thankfully I have two but I would rather have them both working correctly

Cheers

Had a bit of a result with this, as I have only had my iStick a couple of weeks so I contacted the supplier I got it from and they have agreed that 2 weeks and the heads are stripped is a bit suspect so I have sent it to them to check and hopefully replace when they get it back in stock !!

So a note for those at Eleaf if they are watching this thread for the version 2 Please Please Please make sure that you are using a good quality 510 connector so we have less chance of the threading getting stripped

But otherwise very happy with the iStick, I know people have issues with the whole rms/mean volts thing but being quite a newbie vapour and this being my first real "mod" shall we say I am happy to build my kanger coils to a ohms that suit and start low with the wattage until I get to the sweet spot that I like.
 
I just ordered an Istick and nautilus mini to replace my ego twist paid $55.00 total shipping and all. says i will get it Tuesday I am so excited!!! I also saw Vapor Joes has the Orchid version 4 for $12.53 I was thinking of getting it for my first rebuildable any thoughts?? I love Vapor Joes Blog saves me from looking around for better prices!!!

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.

Does anyone know if this issue has been resolved? I've got a couple coming tomorrow. If I can't get below 4.2 Volts on a full charge, these will be useless for both my wife and myself.

I believe that the thought that an iStick's Lowest Voltage Out-Put is what the current state of the Battery is was Dis-Proven about 300 Pages Ago.

I just received my order from Vapor Tek. Not happy at all. It said Eleaf Istick Box. All I received was the mod, no adaptor or cord.
I contacted them and they said "that's the way we sell it".

Where can I get the adaptor and cord for it?

VAporTek clearly stated it was box only.

Any micro usb cord will work.

As for the adapter, I haven't seen the specific istick adapters anywhere, but any 510 to ego adapter will work.

Agreed. Box only meaning iStick only. No adapter, cable or wall wort. I went for one because I have plenty of adapters, cables and wall worts but I can see how it might be misunderstood as other places are selling with adapters or a full kit with everything.

Excellent! I just happened to see that posted in another thread and missed it here. Had me worried. Thanks!

Yes, the speculation that the Istick will not output lower than the native battery voltage has been dis-proven; however it has since been proven that it regulates the output in 'Aavg' rather than 'Vrms' which means if you set it to the lower range of voltage, the output to your coil may seem closer to 4 - 4.2 volts or native voltage. Most users have been able to simply adjust it lower than we would on other mods to get the same result, so odds are it will work fine for you.

Not to my knowledge. Sorry.

Did you see PBusardo's Youtube review of iStick? He shows you exactly what's going on.

Now this Isn't to Say that an iStick Can Not feel like it is running Hotter than another APV that you may have. Because 3.0v using VAVG is going to Taste Different than 3.0v using VRMS.

How Much Different? That depends on the Ohms of your Atomizer Coil.

Low Ohm Coil => Bigger Difference.

High Ohm Coil => Less Difference.

I Wouldn't Worry. Just wait for it to be Delivered and then Try it. Chances are you are going to Love it.

:)
