Welcome to the new VapeShop.com site

The Eleaf iStick 40W TC is the latest iStick from Eleaf - it is replacing the older iStick 30W. The Eleaf iStick 40W TC is not only an improvement over the iStick 30W in terms of build quality and, of course, adding an extra 10W of power, but it also provides the ability to use Temperature Control coils as an option. 

The Eleaf iStick 40W TC has two modes of operation:

  • Regular variable wattage mode to use with regular kanthal coils (same as previous iStick but capable of delivering up to 40W)
  • Temperature Control mode to use with special Ni Temperature Control coils

The Eleaf iStick 40W TC is the first Temperature Control (Variable Temperature - VT) mod from Eleaf. The Eleaf iStick 40W TC is the latest iStick version from Eleaf - the latest version of the hugely popular iStick series. The Eleaf iStick 40W TC is both a VW (Variable Wattage) and a VT (Variable Temperature) device. The Eleaf iStick 40W TC - as its name implies - can power a coil up to 40W. In Temperature Control (TC) mode - the Eleaf iStick 40W TC is compatible with Nickel coil, and in Variable Wattage (VW) mode the Eleaf iStick 40W TC can use any standard Kanthal coil. The Eleaf iStick 40W TC also comes with a battery capacity of 2600mAh. The Eleaf iStick 40W TC design is similar to the previous iStick 30W version with some improvements, such as, better quality power button - a repositioned 510 connector to perfectly fit any 22mm tank, etc...

The Eleaf iStick 40W TC comes in 4 colors:

  • Black
  • Blue
  • Silver
  • Grey

Temperature Control is the latest trend in the vaping community, it provides the ability to vape at different temperature to achieve the best possible vape. Temperature Control devices are also very helpful to prevent coil burning which is important with nowadays cotton coils.

VS Comments:

At VS we select only the best devices in each category. Our temperature control devices must not only provide the ability to vape at different temperatures, but they must also be easy to use, the first generation of temp. control devices either did not work well and/or were difficult to use. We tested many of them, and had to reject them all, we hoped the technology would improve. We simply could not recommend to our members any of the first generation temp. control devices. Well... our patience paid off, the new Eleaf iStick 40W TC is easy to set up and enjoy. The Eleaf iStick 40W TC is for sure the most economical way to enter the temperature control world of vaping.

Not as good as my old one
I had an eleaf 30 watt mod, which lasted well over a year. I bought this as a replacement because I like the style and size. Although it is decent, it does not hold a charge nearly as long my previous istick. I am a moderate user, and only go up to about 12-13 watts. I try not to suck on it all day, but find that the battery needs to be charged at least twice a day (sometimes more). My old one would go almost all day! Maybe it's just as well because I want to ultimately leave this vaping behind and be done with all vices for good.

Fantastic Starter Kit
I purchased this along with the aspire mini nautilus top piece. It is the perfect way to start it comes with a charger, however is fully charged when you receive it. The battery last a really long time! It's easy to use and has helped me with quitting smoking a ton!! I LOVE IT!! I highly recommend this to anyone!!

Great backup
I use this iStick as a backup...it usually is in my briefcase...but it does the job as expected. It was my first when I changed from the pens and I recommend it to anyone just starting out with the vape experience.

Wanted to Love It
It's a great mod, but my only real gripe is the battery. I could never, even when new, get anywhere close to a full day from this thing. I LOVE the size, the look, the power, the TC option, the finish and all the above, but it just doesn't last long enough. And for reference I normally only have a 1.8ohm Nautilus Mini on this thing for vape on the go. I occasionally throw on a Veritas RDA with a single 1.5ohm build and vape it around 14-16watt, so I rarely push this thing anywhere near its power handling capacity, which makes it that much more disappointing. I've used it for a year because I just throw it on the charger in the car, but it's never been my favorite - which is too bad because it could have been. Not bad.

works great
Just bought one of these to go with my Nautilus Mini tank since I am trying again to get off cigarettes. I set it at 7.5 watts and it vapes Perfect!
Lots of smoke, very smooth, and no burnt juice!
battery life seems to be really good for the price.....
Takes a little getting use to since it is pretty small and the button feels fire button feels loose.
I am very happy with my purchase and will probably have to purchase a second one for a back-up.
Can't wait to try this setup with the new Clapton coils!

This is my first temp control mod. I didn't want to jump into a $100+ device before I got a chance to experience the nickel coils and temp control first. I had low expectations because of the price, but was really surprised at the performance. It does a superb job, and I am definitely happy with my purchase. Why Spend more $$$$ this will definitely do the job!
