Eleaf iSmoka iStick TC100W Box Mod Kit

There is no uncertainty that box MODs have been the most popular vaping devices that have hit the market over the past year. Although they were initially available in limited amounts, virtually all leading manufacturers now offer several models. One of the very first to popularize and commercialize box MODs is Eleaf with their immensely prevalent iStick line. Since the release of their iStick 20W, which broke sales records across the globe, they have unleashed an array of iSticks, all of which have been incredibly popular and well-liked. Eleaf has now released their latest in the long line of iSticks—the iStick TC 100W Box MOD.

The Eleaf iStick TC 100W represents the culmination of a colossal amount of research, development, experience, and expertise in the manufacturing of regulated box MODs. Combining the latest technology with an array of wonderful features and the finest materials, this gem is truly a masterpiece. The Eleaf iStick TC 100W is extremely powerful, technologically advanced, feature-rich, and as with all iSticks, surprisingly affordable. These superb characteristics make this new device one of the most exciting yet to hit the market.

The body and frame of the Eleaf iStick TC 100W Box MOD is constructed with aerospace-grade aluminum alloy. Technically referred to as 7075-Grade Aluminum, this state-of-the-art material is widely used for performance bicycles, aircraft, and high-powered rifles. Due to its unique combination of zinc, copper, magnesium, silicon, manganese, chromium, titanium, iron, and other metals, aerospace-grade aluminum has the strength comparable to many steels, while remaining lightweight and extremely resistant to corrosion. Although relatively costly, these marvelous qualities make this particular alloy perfect for box MODs.

Aesthetically, the Eleaf iStick TC 100W Box MOD is a truly beautiful device. It’s curvatures and understated overall design gives it a delightfully sleek and elegant look. Eleaf carefully engineered the iStick 100W TC so that it is exceptionally ergonomic, making it astonishingly easy to hold and use throughout the day. Unlike previous iStick models, the TC 100W is furnished with a side-positioned fire bar, rather than a standard fire button. This substantially adds to the ease of use, making it very comfortable to operate, regardless of whether you are right or left-handed. Eleaf brilliantly included a lock/unlock switch that enables you to prevent the fire bar from operating while not in use. This helps eliminate the possibility of accidental firing while your iStick TC 100W is being carried in your pocket, purse, or bag.

The front of the Eleaf iStick TC 100W Box MOD is equipped with a large OLED screen, which not only considerably adds to the aesthetic appeal of the design, but also brings a host of important information to your fingertips. By activating the iStick 100W TC’s OLED screen, you will be able to view and monitor the output wattage, temperature setting (when in TC mode), the remaining battery life, the resistance of the atomizer coil, the duration of your puff, and any errors that may potentially arise while in use. This amount of available information allows you to efficiently and effectively use and tweak your iStick TC 100W effortlessly according to your preferences.

The top of the Eleaf iStick 100W TC Box MOD is equipped with a flush 510-thread connector, allowing you to use it with the majority of popular tanks on the market. The middle of the connector features a spring-loaded, self-adjusting center pin, which virtually ensures a secure and solid connection between the iStick 100W TC and the clearomizer, atomizer, or tank you are using with it. This is a particularly beneficial quality for those who alternate between various tanks, as many are equipped with connectors of different lengths.

Internally, the Eleaf iStick 100W TC Box MOD is equipped with a cutting-edge microprocessor, allowing it to offer an array of features and options. The chip is not only progressive and very up-to-date, but permits you to keep it current as new technologies are made available. By plugging the iStick TC 100W to your computer via the included USB cable, you will be able to update the firmware as the latest versions are released. This eliminates the need to replace the device as a whole when the existing firmware is rendered obsolete.

One of the many splendid attributes of this device is its variable wattage and voltage capability. Using the well-proportioned tactile operation buttons on the face of the body, you can accurately adjust the output wattage from between 1W to a notable and satisfactory 100W, in 0.1W increments. This wide spectrum of available power output enables you to use the iStick TC 100W with virtually any resistance atomizer coil you wish, making it tremendously versatile. In fact, this masterpiece can accommodate atomizer coils with resistances as low as 0.05 ohms, and as high as 3.5 ohms, depending on the mode the device is set to.

Adding to the versatility of the iStick TC 100W is its temperature control and sensing capability. When used with titanium, nickel, or stainless steel atomizer coils, this incredible box MOD allows you to monitor, set, and adjust the temperature of the atomizer coil itself. This allows you to customize the temperature of the vapor that is produced, and therefore your overall vaping experience. You can increase the temperature if you fancy warmer hits, or reduce it if you enjoy cooler ones. Moreover, the ability to fine-tune the coil’s temperature helps eliminate burnt hits often experienced with standard atomizer coils. The overall result is sensational flavor production, coupled with wonderfully large vapor clouds.

Intelligently, Eleaf designed the iStick 100W TC MOD to accommodate two external 18650 batteries (sold separately). This was a careful and deliberate decision by Eleaf, as external batteries offer a couple valuable benefits that cannot be enjoyed with devices furnished with internal, non-removable batteries. Regardless of the size, type, or chemical composition of a rechargeable battery, all will slowly hold a lesser amount of charge until it fails to hold a charge whatsoever. When the time inevitably comes with internal battery devices, you are forced to dispose of it entirely, as the battery cannot be replaced. However, with external battery MODs, you can simply replace the failed battery, allowing you to continue using the device itself—a substantially less expensive option. Additionally, since the iStick TC 100W is powered by external batteries, it affords you the ability to carry fully-charged spares with you at all times, in the event that the batteries in use die while you’re out and about. This helps ensure that you will never be stuck without an operational vaporizer to use.

Eleaf conveniently designed the Eleaf iStick 100W TC Box MOD so that battery removal and replacement is extremely easy. They accomplished this by making the battery dual door covers magnetic, allowing you to effortlessly take the cover off and snap it back in place without the need to unscrew any parts. Another incredible and unique feature is the iStick TC 100W’s parallel circuit configuration, which allows you to operate the device with a single 18650 battery or two of them. When a single battery is in place, the maximum output wattage is 75W, while the MOD can offer 100W when both batteries are in use.

However, in the event that your batteries do die and you don’t have backup batteries available, you can use the Eleaf iStick 100W TC Box MOD’s sensational passthrough feature. This capability permits you to use the device while it is being charged. The ability to simultaneously vape and charge means you will always have a functioning vaporizer as long as you are near an outlet, computer, or other device with a USB port that is capable of charging other devices, such as an external portable battery pack. Moreover, if you purchase a USB car adapter, you will be able to charge and vape while in the car—an extremely convenient capability, particularly while on long drives.

However, with as much meticulous attention to craftsmanship, ergonomics, technology, and features that Eleaf placed in engineering the iStick 100W TC MOD, they did not overlook safety. This spectacular device is armed with a wide range of safety features that offers you comfort in knowing that you are protected while using it. The iStick TC 100W is equipped with Low Voltage Protection, Atomizer Short Protection, Temperature Protection, Short Circuit Protection, Reverse Polarity Protection, Temperature Alarm, and Lock/Unlock capability.

From its gorgeous aesthetic design, to its high-powered and feature-rich internal mechanics, it is easy to see why the vaping community is so enthusiastic about the Eleaf iStick 100W TC Box MOD. Available in three beautiful colors, this gem is an affordable way to obtain sensational performance.

Still works after many years!

Similar to another comment here, I bought the eleaf istick 100w TC from a local shop when it first came out some unknown amount of years ago. I have minor wear and tear, but tbh my lower magnets just need to be glued back in again and its still great condition even after dropping this thing over many years lol. I have never had firing issues, and the buttons/mechanics are built like a tank on these OG units. The main reason i bought this is for the squeeze door firing button, and also that it fits well if you have larger hands. If you can find one, grab it, throw some quality 18650s in there, and enjoy.

Still going strong!

Cane on the site for something else and saw the page was still up so I had to add a review. I have had one of these since they came out. I still use it everyday. It has taken quite a beating. It has never failed. Its scratched, magnets came loose, display is dim but it fires every time with zero issues. I wish everything was made how these were. I miss old school mods like this one. I have others, but this one comes with me everyday

Genuine Eleaf™ iSmoka iStick TC100W Box Mod Kit

Good mod and easy to use. Great service from vapor authority also in getting me all setup. Recommend this to anyone looking for a great mod that's not to pricey.

Genuine Eleaf™ iSmoka iStick TC100W Box Mod Kit

I'm a HUGE fan of Eleaf in general, but this 100w mod is the best! I get great use from this and the price is unbeatable!

Genuine Eleaf™ iSmoka iStick TC100W Box Mod Kit

I am really disappointed in this mod. First I have to say that VA was helpful in working with me on issues with the lock button. The first one I got the lock button was just about impossible to move. I sent it back and they agreed that it was unusually difficult and sent me another one. The lock button is much better but the rest of the performance of the mod is poor. The paint didn't last a week and rubbed off to metal on both sides without any rough use. Any tank that doesn't screw all of the way in to where the base is resting on the mod will cause the tank to wobble. The screen is very small and not very bright. It does the job of firing the coils I use of about 1 ohm and it seems to be OK as far as battery life goes, so I'll use it until I find something else but from my experience with this one I don't think I'll be buying any more Eleaf products in the future.
