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

    Great devices so far, tiny and great battery life. Eleaf can be hit or miss quality-wise.

  • Average battery life

    Posted by Ronald L. on Sep 13th 2024

    just ok

  • Easy to use... Nice upgrade

    Posted by Dustin Carter on Aug 2nd 2024

    I had an original tc40w eleaf when they came out... And It still works (around 10 years old) Unfortunately, the display stopped working when I tore it apart recently (I tore the cable off). Like I said, it still works, just have to guess the wattage when adjusting it. Anyway, these things are pretty sturdy and made well. The battery lasts a while before charging, depending on your coil resistance. I was hoping to get the type-c version, and I did. Hopefully this one lasts as long as the original. ???

  • Love the ELeaf
