Key Specs

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 2600mAh 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.  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).

Questions & Answers

QI would like to see the old 80w vapes I have used that style vape for 12 plus years old style box stands alone and old colors

Anonymous · Jul 21, 2026

AI'm reading this as you're looking for older 80W-style standalone box mods in the classic colors you've used for years — this page is the iStick 40W, which isn't that device. The iStick 40W is a compact variable-wattage box mod that goes up to 40W (not 80W), with a built-in 2600mAh battery, and it comes in Full Black, Silver, Grey, Blue, Black, and Brushed Silver at $28.95. If there's a specific older 80W model you're trying to track down by name, email info@centralvapors.com with the model or a description of the one you remember, and the team can tell you what's currently in stock that matches that stand-alone box style. — cameron

  • ELeaf batteries

    Posted by Rebecca on Jul 21st 2020

    The 40W eleaf batteries are so much better than the 30W batteries. Eleaf needs to upgrade their technology if they want to keep customers. Thanks Central for carrying this product! :)

  • These are the best!!!!

    Posted by MIKE FLORIN CIPRIAN on Jan 14th 2020

    is not good ,,,doesn't work

  • Best I've ever had!

    Posted by Kevin Luneke on Dec 19th 2019

    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.

  • Great Device!

    Posted by Michael Steele on Dec 19th 2019

    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.

  • Work Horse

    Posted by Steve C. on Jul 23rd 2019

    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.

  • Love it!

    Posted by Bobbie on Jun 10th 2019

    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!

  • Great little istick... Eleaf iStick 40W
