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).

  1. ?? 4 Star Review

    Posted by on Oct 24th 2023

    Good battery; The last one owned lasted 3 years. Recommend.

  2. Product and customer service questionable 3 Star Review

    Posted by on Jul 22nd 2023

    Purchased a defective unit. Returned it, expecting to receive another. They gave me store credit instead, despite my request otherwise. A few weeks, multiple messages sent and I had to pay ten dollars shipping to get the replacement. That's 20 dollars in shipping to get a 30 dollar item. I stated that this would be my last purchase with them, no response. I will not be returning.
    Oh and the newer usb-C units last half the time of the older ones.

  3. Battery not great 1 Star Review

    Posted by on May 26th 2023

    Received this battery and it dies so quick. Received a replacement and the same thing happened. I’ve owned 3 of these batteries in the past and they would last me the whole day - these new ones only last 1/4 day.

  4. good size 4 Star Review

    Posted by on Feb 13th 2023

    I enjoy the small size, fits in pocket well. I am somewhat rough on hardware,unintentionally, so lifespan is often short. I order more frequently so I always have a working ecig. I do wish that they had a longer battery life though.

  5. battery life is much less 2 Star Review

    Posted by on Jan 10th 2023

    The batteries on these recently purchased iSticks go dead much faster than prior purchases of the same item.
