Eleaf iSmoka iStick TC 40W Temp Control Box Mod

Although box MODs existed prior to the iStick release, there is no question that the Eleaf iStick line has popularized it to a higher extent that has not been seen before. The Eleaf iStick has proven to be the single most popular box MOD released to date. It is, therefore, a great pleasure to introduce the latest addition to the iStick family—the Eleaf™ iSmoka iStick TC 40W Temp Control Box Mod Kit. The “TC” stands for “Temperature Control,” which is the feature that sets this device apart from the other members of the iStick lineup.

Aesthetically, the iStick 40W Temperature Control Box MOD is virtually the same as the iStick 20W and iStick 30W devices. The size, shape, and overall appearance are nearly identical. The two primary differences are the round fire button and the ventilation slots located at the top of the device. The only other aesthetic difference between the iStick 40W TC and the iStick 20W/30W is that the magenta color is not offered and has been replaced with gunmetal grey instead. Eleaf paid careful attention to making the iStick 40W TC, as well as all of the others in the iStick line, incredibly ergonomic. This added functionality makes means that the iStick 40W fits very comfortably in your hand, making it easy to to have with you, and use throughout the day.

As with the other iSticks, the Eleaf™ iSmoka iStick TC 40W Temp Control Box Mod Kit is a variable voltage and variable wattage device. The wattage can be adjusted up to a satisfactory 40W, allowing it to be used with a wide array of clearomizers. With 40 watts of available power, the iStick 40W Temperature Control MOD can accommodate standard clearomizers and sub-ohm clearomizers alike. Eleaf also brilliantly designed the iStick 40W with a spring-loaded center connection pin, which will virtually ensure a solid and secure connection between the iStick and the clearomizer, glassomizer, cartomizer, or atomizer you are using.

However, what truly differentiates the Eleaf™ iSmoka iStick TC 40W and included Temp Control Box Mod Kit from the others in the iStick line is the fact that the iStick 40W has temperature control functions, and capabilities. Temperature control represents the cutting-edge in vaping technology and provides for a truly enhanced vaping experience. Box MODs and Advanced Personal Vaporizer with temperature control are capable of actually governing the temperature of the atomizer coil, which results in a truly superior quality of vapor. Not only is the hit smoother and cleaner, but also extremely flavorful. Moreover, temperature control devices coupled with Nickel coils, virtually eliminate dry and burnt hits sometimes experienced with Kanthal resistance coils.

Eleaf™ iSmoka iStick TC 40W Temp Control Box Mod Kitis not only a beautiful and feature-rich device but powerful and secure as well. This remarkable box MOD sports a hefty 2,600 mAh battery capacity, providing for long life and stability. It is also armed with several safety features, allowing you to vape with peace of mind. The iStick 40W Temperature Control MOD is equipped with Over-Discharge Protection, Low-Voltage Protection, Automatic Shutoff, and On/Off capability.

If you are a fan of the iStick series or are thinking about entering the market for the first time, the iStick 40W TC should definitely rank highly on your list. Coupled with Nickel (Ni-200) Atomizer Coils, this wonderful device will provide you with a truly superior vaping experience.

NOTE: This kit does NOT include tank or wall adapter

As usual I am very happy to do business with you. I have referred you to my friends and I know they will also be satisfied.

Excellent mod

I own several 30w units so I’ll be comparing this to those.
Good quality construction as always. I like the new fire button. The unit is a bit bigger than the 30w and it’s reversed where the button is in relation to the tank. Not a problem just different. It uses USB-C to charge so my old cords won’t work. The screw in part for the tank is better than the old ones.
The only negative is battery life. With the 30w I can vape about 3ml of juice in a charge. With the 40w only about 2ml. This is strange considering the specs say the 40w has a 2600 mAh while the 30w only has 2200.
Overall a good product. I would buy again.

Not like they used to be

I've used the eleaf box mods for many years and they've been great. I ordered a 20w with USB3.0 recently and found that it only lasted about half as long as the old micro-USB ones. Thinking it might have been a fluke, I ordered a 40w as well - same issue. So quite disappointed.
