Full Description

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.

So Far So Good
I replaced a 2-year-old Eleaf iStick 30w model with this one; the 30w lasted about 700 cycles (charges) so no complaints there. This one is slightly larger and heavier (expected) but the charge life has double the longevity- much better for not having a USB handy. My only complaint is that the 30w had better ergonomics with its hand-hold position; it had the tank mount toward the front of the control face and this one is located toward the rear. Not a big deal, I've already adapted to that new muscle-memory habit after using for a week. Plus the fact that it was $4 less than the 30w price from 2 years ago and I'm very satisfied with the new iStick TC40 !

We liked the 30W, but we love these 40W units. We just use the EVOD type tanks and 2.5 ohm coils. Set at 3.5-4.0W, these batteries last for DAYS before recharging.

Warning to anyone who uses the low ohm coils: when getting a new battery, check the wattage. Mine was factory set at 20-something and I didn't check it prior to use. It instantly blew the coil....taste was pretty nasty, too!

I purchased two of these little monsters. One in black the other in silver. Very easy to use. With a touch of a button in changes to TC. Enough power to operate basically anything that has a 510. Fast shipping and excellent packing. Thanks Vapeshop!

I have been a fan of Eleaf's for several years now. I have purchased 4 Eleaf mods, 3 of the 40W. I am not happy with my most recent purchase. Consistent issues with the mod recognizing the tank. I finally gave up and purchased another brand

I love this thing
Choose your temp Watt or Volt with a Ohms reader on it.  Cheaper than many atomizers but does everything those expensive mods do.  I have no idea why someone would pay 100bucks or more for an ecig when you can pay 30 and rocj this thing.  I bought one, lasted 3 years and bought another after dropping it at least 599 times falling asleep in my chair it keeps on working.
