Full Description

This is the Eleaf iStick 40W Battery, VS also offers the Eleaf iStick 40W TC kit. 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 both 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 like a 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

Eleaf iStick 40W TC Battery Package Contents:

  • 1 x iStick 40W TC
  • 1 x User Manual

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

  • Dimension: 36.2mm x 22.3mm x 77.3mm or 3-1/16"L x 1-3/8"W x 7/8"D
  • Passthrough: The battery can be recharged while vaping
  • Ultra Large Battery Capacity: 2600 mAh
  • Operating Wattage: From 1W to 40W
  • Output Voltage: 0.5V-8.0V
  • Connector Thread: 510 stainless steel thread and spring loaded connector for best connection

Exactly what I need
This battery is actually the 2nd time I've purchased. It is small, compact, and works with every cartridge. I usually use it at under 10W settings so the battery life last forever, I'm talking about 2 weeks+ of use before having to recharge.

If I lose this, I am definitely purchasing another one.

ONE THING MISSING!
The previous I-stick models allowed you to lock the voltage (or wattage) setting so that it wouldn't get changed while in your pocket. This new one says you can lock it in Temp mode by holding the up & fire buttons.. and you can, until you take a hit and then it returns to variable wattage mode and the lock is off. maybe because I don't have nickel coils??

Can anyone tell me how to lock the voltage setting so I don't burn up coils when it gets bumped to full power in my pocket???

Eleaf 40W TC Battery
This is my second iStick battery.  The first one I had lasted 5+ years, so I knew it was a good one.  This new one is upgraded from my first one, and the only (minor) problem I'm concerned with is the W and V setting for my 1.6 ohm atomizer.  It is not compatible with the TC feature, so I set it on 5.0W. The ohm says 1.71. I can't find the right setting for the 1.6 ohm. I don't want to damage the unit or take a risk of it overheating.  I love it otherwise!

Eleaf Istick TC 40W
This is my second istick and I couldn't be happier with this battery. It charges rapidly and stays charge for a day or two.

Add a charging cable!
The battery has a nice feel and while I haven’t had very long, it seems to have a good battery life.  It has a good deal of versatility though a little overly complicated to make changes to settings.  However, my chief complaint is that it didn’t come with a charging cable. Come on, I would be ok without including an AC adapter but at that price, at least throw in a cheap usb cable.

**VapeShop.com response**

We have two different Eleaf 40W batteries. The express kit includes the USB cable and an eGo adaptor whereas the other is only the battery. This gives our customers options and a way to save money if you have 18 USB cables lying around the house.
