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).

    Ordered 40 w. Was sent 30w instead. Very poor quality based on prior purchases of same product from other companies. Emailed them numerous times plus phone messages and got no response. Will never order from them again.

    This mod is super cute small and compact but I should of went with 80w I have a fireluke tank works with the mod but vaping around 30w usually around 33-35 This compact mod battery power dies very very fast I should of went with the istick 80w with larger battery. I would definitely recommend this for a vaper that is a beginner you will know quickly if its enough power for you

    I've been using a 30W for over 5 years with KrangerTech EVO2. I like the 40W after getting used to watt vs. volts.
