Eleaf iStick 40W

The Eleaf iStick 40W is an innovation of the iStick series devices, adopting the element of temperature control. Temperature control introduces a unique vaping experience without any dry hits by adjusting the temperature setting. Despite being small in size, this Eleaf iStick can reach 40W and has a 2600mAh battery capacity. Stainless steel threads and an elastic spring connector ensure this device with high wear resistance.

The iStick 40W is a variable voltage and variable wattage vaping device. It can produce massive vapor within an output range between 2 and 10 volts, or 1-40 watts. It can be used with nearly all types of atomizers from as low as 0.2Ω all the way up to 5Ω. Although the size is slightly larger compared to other iSticks, the iStick 40W is still a very compact mod that is easy to grip and carry around. You'll be able to enjoy continuous vaping for hours on end, thanks to the incredible 4400mAh lithium cell.


The USB charging port of the iStick is located on under the base to make passthrough vaping easier. Charge this eleaf iStick in an upright position through, a computer, or a wall outlet port for 5 hours to replenish full power. The iStick features a sharp, easy-to-read digital OLED screen which displays the current voltage or wattage, remaining battery life, ohms resistance of the atomizer, and a vape timer.


Threading for vape tanks on the iSticks has always been a strong suit, and the 40W iStick mod has retained the original 510 design of its predecessors. The durable spring-loaded connector pin guarantees a solid connection between battery and tank, and the wear-resistant stainless steel thread ensures a secure fit with any 510 atomizer, clearomizer, or cartomizer. The Eleaf iStick 50W is shipped with an eGo adapter so you can also use eGo threaded tanks. Along with upgrades to its capacity, aesthetics, and features, the company Eleaf has also beefed up its iStick safety. Standard safety protocols such as short circuit protection, low voltage protection, automatic shutoff, and locking capability are in place, as well as additional overheating protection that shuts down the device when the internal temperature rises to 158 degrees Fahrenheit (70 degrees Celsius).

    This is my 2nd Eleaf Istick 40, works like a champ and lasts me 2 whole days before needing a charge. The first one I bought last April and has been used daily without issue.

  3. Great Device! 5 Star Review

    I'm fairly new to vaping and have been using the e-go pen vapes mostly, but upgraded to this. The battery is very powerful and holds a charge for a long time even when puffing on it all day and night. I like the features like temperature control which works great with the sub ohm tank I recently got. Also included the 510 connection adapter so I could still use the tanks I had with my old pen vapes. Overall I'm pretty impressed with it. Will probably be getting another as a backup.

    These are like an old friend. You know they will be there for you when you need them. I have used these for several years now and you can't get a better device for the money. Easy to use, very dependable, built like a tank, I love them.

    Look, I don't know much about mods, so I can't tell you specks, I can tell you that this was my fav, and I now have 2. They travel well, (dropped a lot) and they charge while vaping, and they are easy to adjust to get the right amount of cloud and taste. I love mine and got a 2nd for when I have to run out the door, one is always charged up and ready to go!
