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.  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).

    I have been using the Eleaf I stick for years and the quality of this performance including battery charged time is not positive.

  2. Best Eleaf iStick Yet! 5 Star Review

    I love the eleaf 40w, it's so easy to use and charges much faster with the new USB-type c connection. I personally haven't noticed any downside to the new Type C charging port. So far, it's actually my favorite of any eleaf isticks I've owned.

    Batteries fo not last very long. We have used these for years happily. May need to change type. Kind of a waste of money.

  4. Change in charging port 1 Star Review

    Posted by on May 21st 2022

    I have used these mods for 4 plus years. I recently bought 2 new ones because I always like to have one charged. The manufacturer has changed the charger from the old charging to the newer one which I think is called type C. They dont hold a charge like the older type did. I am LUCKY to get 2 maybe 3 hours MAX of vaping before its flashing from low battery. I exchanged my last 2 that were all black on black (which I have never seen as an option before) to the older colors hoping that would solve the issue. Central Vapors did as I asked but the new ones came with the same charging port and the issue remain the same. Unfortunately I will not ever buy this mod again. It is unfortunate because I have loved these for so long. They are light and easy to put in you jeans pocket etc. Used to be a great mod for the price! NOT ANYMORE!!!
