Hello everyone.
The device reviewed below belongs to the “electronic cigarettes” category.
Welcome.
The Eleaf iStick TC100W box mod is a continuation of the line of popular budget devices from the Chinese company Eleaf. The main difference from its older brother (and the decisive factor for me when purchasing) is that the hero of the review has a temperature limiting mode (thermal control) on nickel, titanium and, most importantly, on stainless steel.
I ordered the box on January 27th, I was prepared for the fact that they wouldn’t have time to send it before the start of the all-Chinese drinking binge, but by some miracle I was lucky) I picked it up at the post office on February 19th.
At the time of purchase the price was $32.39, the final price with points and e-package delivery was $24.68
The box mod is packaged in a box made of thick cardboard, familiar to Eleaf devices. Notice the Firmware Upgrade icon. 
On the back of the box all the main features of the device are listed and there is a sticker with an originality verification code. 
Inside the box: box mod, USB cable for charging and firmware, instructions in several languages (Russian available). 
The body of the box mod is made of metal. At the top of the device there is a 510 connector with steel threads and a spring-loaded brass pin and a fire button lock switch. 
In the area of the connector, two chips have already been discovered on the paint (ceramic coating?) 
At the bottom of the case there are 5 “ventilation type” holes and a microUSB connector for flashing the mod and charging batteries. 
On the front side there is a display, “+”, “-” buttons and a mode selection button 
On the reverse side there are 5 more holes for ventilation, Eleaf and iStick TC100W logos 
The batteries in the device are located in different compartments under metal covers that are attached to the body using magnets. The inner surface of the seats is marked +-. The contacts are brass, the lower contact is spring-loaded. 
The lids are the same, they fit very tightly, do not rattle, do not play, or fly off. If lost, a set of replacement covers can be found in Chinese stores for 5-6 dollars.
Under one of the covers at the top of the device there is a Fire button. The button travel is about 1 mm, with a distinct click.

Compared to "big brother" 
Boxmod can work in wattage, thermal control and mechanical modes.
Briefly about the variable watt mode: the coil resistance is supported from 0.1 Ohm - 3.5 Ohm, output power from 1 W to 100 W. In variwatt mode, the duration of the puff is displayed.
Mechanical mod mode (bypass) - the helix resistance is supported from 0.1 Ohm - 3.5 Ohm. Pressing the Fire button also displays the duration of the puff.
Thermal control mode (TC-Ni, TC-Ti, TC-SS) - the box mod works with coils made of nickel, titanium and 316 stainless steel. Supported resistance 0.05 Ohm - 1.5 Ohm, temperature adjustment 100-315°C.
It is also possible to manually adjust the temperature coefficient of the spiral material and save the obtained values in the form of three presets (M1, M2, M3). 
In thermal control mode, the device display shows: remaining battery charge, resistance of the installed coil, selected temperature in degrees Celsius or Fahrenheit, selected coil material or TCR preset (Ni, Ti, SS, M1, M2, M3), output power. When the resistance is locked, the Ω icon changes to the image of a lock. In short, the same as in 40 and 60 watt isticks. 
Boxmod can measure battery voltage (one battery). To do this, you need to install the battery in any of the seats, turn off the device by pressing the Fire button five times and hold down the Fire and “-” buttons. The instructions allow the use of batteries with a potential difference of no more than 0.3V. 
By the way, about the instructions. It is very detailed, written in clear language and has 13 pages.
Let's move on to testing in practice. I bought the box mod for the sole purpose of testing thermal control on stainless steel. I successfully used stainless steel in variwatt mode on my old 100V iStick, so after unpacking the new device I simply screwed an atom onto it with already installed spirals with a resistance of 0.26 Ohm. I chose the SS mode, set the power to 50W, the temperature to 200°C, pressed Fire... and grabbed a mouthful of excellent high-quality smoke. It's a shame. In short, it turned out that on firmware 1.00, with which the device came to me, thermal control on stainless steel does not work.
- downloaded firmware 1.10 from here, flashed it in two clicks - the TC started working, the maximum power of the device increased to 120W.
General impressions and conclusions:
Compared to the previous 100W iStick, the device under review has slightly decreased in size, but gained weight. The battery charge is enough for me to use for a day, just like on the old “100-watt” one. After changing the firmware, we get a 120-watt box mod with correctly working thermal control, pleasant appearance and other goodies, such as replaceable indestructible metal covers. At a price of 33-36 bucks, I see only Cuboid from Joyetech as the iStick's competitors.
Thank you for taking the time to read the review. I probably missed a lot of things - I’m ready to answer in the comments.
All the best.

Thermal control on Kanthal evic vtc mini - this term will not raise any questions among experienced users of electronic cigarettes. But it can cause a multi-minute “load” for users who have only recently entered the vaping industry.
Let's figure out in order what evic vtc mini is, and how the words kanthal and thermal control apply to this concept. We will gradually understand all these strange words.
The electronic cigarette, from the industry flagship company Jotetech.Vtc, is the older brother of a device called evic-VT, which at one time made some noise in its circles. When developing vtc, the successes and flaws of the previous version were thoroughly analyzed, and a truly interesting device hit the market. It is worth noting that vtc can hardly be called a device for a beginner.
As in the previous model, our baby has a simply gorgeous huge display. This is good news, but more on that a little later.
When developing vtc, numerous requests and comments from users were taken into account, and this led to a clear improvement of the product:
- The older brother has become much more compact and lighter.
- The connector is now located on the button side.
- The chrome on the lids is finally gone.
- Now the mod runs on a standard 18650 battery, which can be replaced very quickly. You can also not remove the battery, but charge it via the built-in charger via a USB connection.
- The shuttle, which was not convenient for everyone, has been replaced with the more familiar plus and minus buttons.
- Power adjustment in thermal control mode varies from 1 to 60 watts.
- Working in the TC mode in general began to show its best side.
- The board in this model does not buzz or tick, as was the case with its predecessor.
- The new matte finish, although it has taken away some of the charm from the device, is now safe to use without a case.
- Very important point that the firmware can now be updated. Updates will expand the capabilities of the board and add new functions.
The improvements are numerous and significant, which indicates serious work carried out on the device. Now let's look at what our mod is basically equipped with. What's under the hood?
Mod equipment
Simply huge compared to competitors o-led display has a vertical location. All the information that you may need when using the device is very conveniently located on the screen and can be read without the need to turn the mod. Instead of the standard battery charge indicator, it is possible to install a puff counter, or a vaping time counter.
Incredibly convenient controls. Switching on, as well as switching off, is done by pressing the button five times.
Technical characteristics of the vape.
Enter the menu by pressing it three times. eVic-VTС Mini can operate in 4 modes:
- Thermal control on nickel.
- TK on titanium.
- Mechmod.
- Variwatt.
There is a lock against changes at the selected power. To do this, press “+” and “-” simultaneously and hold for 2 seconds. The device will continue to operate, but changes to power settings will not be available. Unlocking the Key Lock function occurs in a similar way.
The stealth mode is implemented very competently in this device. This mode is entered by simultaneously pressing the Fire button and the minus button. In this mode, the screen will not work while vaping. If you need to change the vaping parameters, the screen will light up while the value is being changed and go off again. If you just need to look at the information on the screen, then you need to quickly press the Fire button once and the necessary information will appear on the display for a short time.
During the puff, the information on the display changes dynamically, showing the real characteristics of the device at a given second. In the mechanical mode, the voltage and resistance values will change, and in the thermal control mode, the real temperature and power will be shown. The inconvenience of this function is that only in the mirror can you see this data, since after releasing the button the screen will return to normal and go dark after 30 seconds.
The mod contains all possible protection options:
- the mod constantly monitors changes in resistance and adjusts the voltage in real time;
- short circuit protection is constantly working;
- winding resistance in TC mode on nickel and titanium is fixed separately for each selected mode;
The board, in principle, is very responsive and instantly responds to turning it on or off, without long loading times, which occur in most other BBs.
Operating modes
I would like to pay a little attention to the operating modes of this device and explain the main points of each of them.
The device has several main operating modes: VW (variable watt), Temp Ti, Temp SS, TCR, Bypass, Start. To switch between modes, press the main button 3 times.
Variwatt
This mode allows the user to control the device's power output from 1 to 75 watts.
In this mode, the following characteristics are displayed on the screen:
- Power, power.
- Volt, voltage.
- Menu showing additional information
- Amp – current strength;
- Puff – number of puffs;
- battery charge.
To select the desired parameter, press the main button three times and select the desired parameter. To reset the number of puffs or vaping time, you need to select the desired characteristic and hold down the main button for a few seconds.
Bypass mode
This mode will give the user of an electronic cigarette the opportunity to supply voltage from the battery directly to the atomizer, that is, work in mechanical mode mode, but with short circuit protection. The resistance of atomizers that supports the device in this mode is from 0.1 to 3.5 Ohms.
In bypass mode, the display will show the following characteristics:
- Power, power.
- Volt, voltage.
- Coil, atomizer resistance.
- A menu that displays additional information.
The following options will be displayed in this menu:
- Amp – current strength;
- Puff – number of puffs;
- Time – total puff time, measured in seconds;
- battery charge.
Thermal control mode
In thermal control mode, the user can control not only the output power, but also the maximum temperature of the coil, which is set in the atomizer. Controlling the overheating of the coil is very important to prevent the coil from overheating and thereby increase its service life. But this is not the only main function of thermal control.
In mods with thermal control, the most the best material, as practice shows, is titanium. This will provide better temperature control and ultimately reduce battery power consumption. In addition, titanium has a fairly high resistance, which will make it easier to customize the device for this metal. If we consider the physicochemical characteristics, titanium will be the safest material for a spiral, unlike nickel.
It is around this metal that the most controversy flares up on forums and in user circles. If we consider nickel as a material for the spiral in a device without a TC, then there is some risk. In case of overheating, nickel releases some toxic substances that tend to accumulate in the human body. Over time, this effect will cause negative consequences.
It is generally accepted that devices with thermal control completely relieve the user of this problem. Scientists say that the danger is not going away. The only difference is that the amount of toxins released is several times less.
The main risk group for nickel vaping is people with individual intolerance or allergic reactions to nickel evaporation products. Laryngeal edema is the easiest thing a person can expect. Or there may be consequences that are invisible, but with a much less favorable outcome.
Regarding nickel, people are divided into 2 camps. If the first sound the guard about nickel soaring, then their antagonists provide specific numbers and arguments. There are 2 cases of complications from nickel vaping per 1000 people. But statistically this is an indicator of danger. And if we consider the physical overheating of nickel, then the wire must be used for a long time at a temperature of about 600 degrees, which is impossible with modern devices.
In its standard configuration and software Our device cannot run on Kanthal.
TCR mode
TCR mode – temperature coefficient of resistance. This mode will allow the user to adjust the TCR for the metal that is used in the evaporator. This means that if the TCR value of the metal used in the evaporator is known, then the user will be able to use the evaporator in temperature control mode.
For some materials, TCR values are important:
- nickel – 600-700;
- NiFe – 300-400;
- titanium – 300-400;
- stainless steel – 80-200.
Kanthal is not included in this table because basic settings devices do not allow vaping on this material. But this problem was eliminated with the release of firmware v3/0 for Joyetech eVic VTC mini.
This firmware brought the following points to users of this device:
- new interface;
- faster scrolling by watts;
- in VT mode the spread is now from 0.05 to 1.5 Ohms;
- The mod should now automatically recognize 304 and 316 stainless steel;
- new TCR mode – mode manual installation temperature coefficient.
Exactly last point and I would like to pay attention because it is this innovation that will allow us to establish the temperature coefficient of the wire, which was not previously officially supported.
You can find the firmware itself on the manufacturer’s website and related forums, and there you can also find tables of characteristics of different metals and calculators that will allow you to make correct winding calculations.
Steam, don't oversteam
Now even the most inexperienced user has a more or less clear picture of what the difficulty of vaping kanthal on the eVic VTC mini was.
With the exit latest firmware this problem has exhausted itself, and the user will again begin to discover new horizons for vaping such a cool and modern device. We will wait for new firmware and new features for our mod.

When adjusting the temperature, when the upper or lower limit is reached, the device automatically switches from Celsius to Fahrenheit and vice versa.
Power adjustment:
Power adjustment: While the power menu is blinking, use the adjustment buttons to change the power. Press the main button to confirm your selection.
Message “New Coil, Same Coil”:(6)
If you are installing an evaporator with a higher resistance than the previously installed evaporator, you may need to "upgrade" the base evaporator resistance at room temperature.
After disconnecting the atomizer from the device, press the main button to “reset”, and then when you attach a new atomizer, you will see the message “New Coil, Same Coil” on the display. In case you have indeed replaced the evaporator with a new one, press the “Right” button.
You can see the same message if you installed the same evaporator, but it has a high temperature (it did not have time to cool down) and, accordingly, a higher resistance than it had at room temperature. The device's electronics need confirmation that it is still the same evaporator with the same "base" resistance - so when the message appears, press the left button, thus confirming that the evaporator has not changed.
Do not forget to correctly perform the steps described above for the correct operation of the thermal control modes.
Attention!
1. In temperature control modes, resistance up to 1.5 ohms is maintained. If an evaporator with high resistance is installed, the device will automatically switch to variable watt mode.
2. If you accidentally try to use the Kanthal vaporizer in one of the temperature control modes, the device will automatically switch to vari-watt mode after two seconds of vaping.
Error and protection messages:

Creates steam thanks to the heating element. And everyone knows that heating elements need to be serviced and evaporators need to be replaced.
If everything is clear with evaporators and coil windings made of Kanthal, it works in vari-watt mode, and the power is set depending on the resistance. With evaporators and coils based on nickel (Ni) and titanium (Ti), everything is somewhat different: they can no longer be used in vari-watt mode. Let's figure out what gives temperature control mode(TC).
The filling of electronic cigarette mods limits the heating of the atomizer coils to a user-defined temperature. The temperature range set on the power supplies of your electronic hookah can range from approximately 100 to 300 degrees Celsius.
- All this functionality is intended for wires made of nickel (Ni), titanium (Ti), steel (SS), nichrome (NiCr) and other unusual materials.
- Coils made from the materials listed above constantly increase their resistance when heated.
- It is for such materials that the thermal control (TC) mode is intended.
When using any of the above materials as a coil in an evaporator, or in a serviced atomizer, the electronics of the mod in thermal control mode will constantly (up to several times per second) measure the resistance of the coil and supply different power. Thus, the TC mode on mods (power sources of electronic cigarettes) will prevent the possibility of rapid burnout of the coil.
If you use, for example, nickel (Ni) as a coil in the normal wattage mode, the resistance of a nickel (Ni) coil will go up when heated, but the wattage supplied to it will remain the same, which means the power will be too high for the coil and the coil will burst.
Coyles and replaceable evaporators made of nickel (Ni), titanium (Ti), stainless steel (SS) and nichrome (NiCr) should only be used on battery mods with a thermal control (TC) mode.
In addition to measuring resistance, thermal control limits heating to a certain temperature set in the vape device menu.
The temperature limit is set for safer vaping. At extremely high temperatures, over 350 - 320 degrees Celsius, some components of e-liquids become not entirely safe. That is why in temperature control mode(TC) heating temperature will be limited.
Electronic cigarettes without temperature control(TC) are almost unable to heat their evaporative systems over 300 degrees Celsius, but thermal control gives much more confidence.
Replacement evaporators designed for temperature control mode are more durable than conventional ones, with coils made of simple kanthal. While a conventional evaporator with a kanthal coil will overheat and quickly accumulate carbon deposits from boiled liquid and burnt-out cotton wool, thereby quickly failing, evaporators based on nickel or titanium will not overheat too much, and, accordingly, will not collect There's a lot of scale on you.
The service life of replaceable evaporators based on nickel (Ni) or titanium (Ti) is many times greater than their counterparts with kanthal coils.
Summarizing all that has been said, we can highlight several advantages:
- Different materials - nickel, titanium, stainless steel, nichrome - can reveal the taste of vapor from e-liquids in different ways.
- Increased safety of inhaled steam.
- Longer service life of replaceable heating elements.
There are many vape devices that have a thermal control (TC) function:
- Ergonomic battery mod with parallel installation of Eleaf iStick 100 W TC batteries
- The famous hit from the industry's flagships, the single-battery Joyetech eVic VTC Mini
- Very similar to the previous Kanger Toptank Mini
- The most beautiful and stylish Smok R80 Starter Kit, which continues the idea of a “boxed” design.
There are also many clearomizers and atomizers for which evaporators are made on nickel and titanium. Advanced vapers will enjoy using thermal control (TC) by winding coils made of titanium, nickel, nichrome and steel onto the drip. Buy electronic cigarette (electronic hookah) with temperature control mode and replacement evaporators are available on our website, we have a wide selection of mods with thermal control (TC) and replaceable evaporators on nickel (Ni) and titanium (Ti).
