Eleaf Lexicon Kit Review

Eleaf has never really been known for making attractive vaping devices. Take the iStick Pico, for example, it’s a great little mod, does what it’s supposed to, but, in terms of design, it doesn’t really stand out. Which makes the new Eleaf Lexicon that much more intriguing. It’s like nothing the Chinese company has done before; it’s so flashy that it’s almost impossible to ignore. It’s also a technically-impressive mod, putting out a maximum of 235W and featuring all sorts of advanced features. Let’s check it out:

A Look at the Contents

The Eleaf Lexicon comes in the classic packaging – a cardboard box with the assembled Lexicon mod and Ello Duro tank on the front, and a list of kit contents and company information on the back of the box. Fairly common packaging, so there’s no point going into details about it.

Inside the box, we have the Lexicon mod placed inside a plastic holder, next to the Ello Duro tank, a spare glass tube for the tank, and an extra coil head (there is one pre-installed in the tank). Underneath the plastic holder we have a smaller cardboard box, where we’ll find the micro-USB charging cable, a small bag of spare o-rings and gaskets for the tank, as well as user manuals for both the mod and the tank, and several other informative cards.

All in all, it’a nice kit which provides everything you need to start vaping – minus the e-liquid – as well as a few nice extras, like the bonus tank glass.

Design and Build Quality

This is where the Eleaf Lexicon really shines. Don’t get me wrong, it’s also a very powerful dual-battery mod and is packed full of neat features, but there are plenty of those around these days. As soon as you pop in a couple of 18650 batteries, you can tell that it’s main draw is a visual one.

The Lexicon is primarily made of zinc alloy and measures 81mm x 31mm x 45 mm, which puts it in the mid-size category of dual-battery mods. It’s actually a bit shorter than most of my other mid-size mods, but a fair bit chunkier as well, so if you have really small hands, it may feel a bit too bulky. I received the purple version for this review, but the Lexicon comes in a variety of vibrant colors, and it also matches the color of the tank as well.

The paint job was the first thing that caught my attention, even before I got a chance to see the Lexicon’s impressive light show. It looks a lot like the paint job on a new car, so shiny that you can see your distorted reflection in it, but durable enough to last. My Eleaf Lexicon has yet to pass the test of time, but it definitely feels like a quality paint job

In terms of design, the Eleaf Lexicon can be described as a box mod with rounded edges and corners. Two of its upper corners are actually replaced with triangular infinity mirrors, which kind of mess up the whole rectangular box mod look. But its most striking feature is the abundance of LED strips which start to light up the moment you insert the batteries. They are everywhere, on the edges of the mod, on both its sides, even on the power button, so if you’re looking to draw some attention to yourself, the Lexicon is perfect.

We’ve seen LEDs used on mods before, from the old SMOK Xcube 2 to the newer Sigelei Kaos Spectrum, but never as many as on the new Lexicon. If you like flashy mods with extra bells and whistles, this one’s for you. But it’s not as kitschy as you might expect. If anything, the pulsating lights and those triangular infinity mirrors make the mod look more like a mysterious artefact of immense power than a simple vaping device. So if you’re into that kind of sci-fi stuff, you’re probably going to like it.

The Eleaf Lexicon 235W mod features a centered 510 connection, which is always a big plus in my book, as it minimizes the risk of atomizers overhanging. The gold-plated pin is spring-loaded and has quite a bit of travel, so you don’t have to worry about the tank not sitting perfectly flush.

What I don’t like so much about the Lexicon is that it only fits atomizers up to 26mm in diameter, without any overhang. For some reason, Eleaf decided to make the top side of the mod considerably narrower than the device itself, which means that any tank or RDA over 26mm will overhang. Now, 26mm is quite enough in most cases, but if you’re going to make a bulky, 31mm-wide mod anyway, why limit options like this?

The battery door is hinged and very easy to operate. Just slide it outwards and then lift it up, to pop in the batteries, and press down on the cap and slide it inwards to close. There is no rattling whatsoever, the door doesn’t wobble at all, and there’s virtually no risk of it popping open by accident. It also features some battery venting holes, for peace of mind.

The fire button is located on the side of the Lexicon mod, which means you can press it with either your thumb, or your index finger, like you would a trigger. It’s a fairly large, diamond-shaped button, with triangular cut-outs that light up with the rest of the LED strips. It’s made of plastic, but it actually feels quite solid to the touch and it doesn’t rattle at all.

The ‘+’ and ‘-‘ buttons are located on one of the sides of the mod, near the bottom, along with the micro-USB port for charging and upgrading. The buttons match the triangular theme of the device, but they are just a bit too close to each other. I personally don’t have a problem with that, but then again, I don’t have very large fingers. However, I can certainly imagine the frustration of someone with sausage fingers trying to press one of the buttons and accidentally pressing both.

Finally, the display is kind of a disappointment to me. It does its job, displays all the information you need, and it’s definitely bright enough, but it just doesn’t match the overall look of the mod at all. For one thing, it’s so small that it literally fits in one of the corners of the mod, it’s black and white, and it’s one of those old fashioned displays that companies have been around for at least 5 years now. If you’re going to make a flashy, “look at me” type mods, why not go all out and use a more attractive screen as well.

Menu System and Navigation

The Eleaf Lexicon may not have the most impressive screen, but in terms of features and customization, it can holds its own against the most advanced vaporizers on the market today.

To turn the mod on or off, all you have to to do is press the fire button five times in rapid succession. While the mod is on, you can access two different menus. By pressing the fire button three times rapidly, you are presented with a list of available functioning modes – wattage mode, temperature control for three supported materials (nickel, titanium and stainless steel) and three customizable memory modes.

Then, there is the secondary menu, which you can access by pressing the fire button and the plus button (right arrow) simultaneously for a couple of seconds. You’ll see a list of icons appear on screen, but because the display is so small, they didn’t even have space to specify wht each icon does.

Anyway, the first one lets you lock the resistance of your atomizer (only available in temp. control), the second one lets you choose what subparameters you want displayed on the home screen(amps, puffs, puff duration), the third one allows you to activate or deactivate Stealth Mode (turns off the display and the LEDs when vaping), while the fourth icon lets you set the duration and the intensity of the preheat (this is only available in wattage mode). The ‘LOGO’ icon allows you to display a custom logo on screen every time you turn on the mod, but you must first upload one via PC, using a special software. The clock icon allows you to set the cutoff time of the mod, from three different options – 5 seconds, 10 seconds or 15 seconds. There is also an ‘off; options, but this just sets the cutoff to 10 seconds.

Then we have two sub-menus to adjust the duration and flashing patterns of the impressive light show. The first one allows you to select the color that you would like flashing and the pattern you would like the LEDs to flash in. The second sub-menu, lets you choose how long you would like the light to light for – always, 10 minutes or off. If you select the last option, the LEDs will only light up when you press the fire button, whereas with ‘always’ they will stay on permanently.

The last two options in this secondary menu allow you to check the firmware and hardware versions currently installed on the mod, and to check the voltage of each of the two batteries currently inside the mod. Unfortunately, the batteries are not marked in any way, so there’s no way to tell which one has what voltage.

There are also some button combinations you can use, like keeping the ‘-‘ and ‘+’ buttons pressed simultaneously for two seconds to lock the buttons, or turning on the mod with 10 clicks instead of five in order to see the temperature of the circuit board. These are advanced settings that most people won’t ever use, but if you’re interested in learning more about them, you can consult the included user manual.

Battery Life and Overall Performance

Offering a fair estimate on the battery life of a variable voltage mod that uses external batteries is virtually impossible, due to the many variables that need to be considered. What type of batteries are you using, how much power is the mod putting out, how often are you using the mod? These a re all questions than need to be answered in order to accurately estimate battery life.

However, what I can say is that the LED strips do affect battery life. My first experiment with the Eleaf Lexicon was leaving the LEDs always on and seeing if they drained the batteries faster. They did, which wasn’t really a surprise, because there are so many LEDs on this thing that it literally gets hot if you leave them on all the time. I can’t really say if they use up half the battery life, or a quarter of it, but they do have a noticeable impact on it, IF you go for the “always on” option.

With the LEDs off, I got about a full day of use out of two Sony VTC5A batteries, vaping at around 60W, which is comparable to what I got out of them with other mods, like the Augvape V200 or the Smok Procolor, for example. I recon that leaving the LEDs on for 10 minutes, will cut a couple of hours, but it’s a fair compromise, if you want to show off your flashy mod.

In terms of performance, the Eleaf Lexicon has been performing well, for the most part. One thing I’ve noticed with my particular sample is that the fire button does misfire every once in a while. I don’t know if this is a general issue or just something about the unit I received, but sometimes, I would press the fire button, feel the power ramp up and then the power would cut off for some unknown reason. If I pressed it again, everything would work fine again. It doesn’t happen all the time, but I do notice it at least a couple of times a day.

Then there is the power ramp up itself. Good thing that Eleaf included a preheat option, because by default, the Lexicon doesn’t have the fastest power ramp up time. Compared to the VooPoo Drag or the Augvape V200, it feels sluggish, but you can easily fit that by setting the preheat to a higher wattage.

Other than that, the Lexicon works quite well. Once the power ramps up to the desired level, the output feels pretty accurate, which is what you’re most interested in when vaping in wattage mode. It also reads the resistance accurately, and I’ve encountered no weird errors of any kind.

I didn’t really mess around with temperature control a whole lot, especially since I couldn’t tell if the coils for the Ello Duro tank were of a supported material, but also because I’m not a big fan of temperature control vaping.

The Tank

The Lexicon mod was paired up with the Eleaf Ello Duro tank, one of the several tanks that the Chinese company launched in recent months, and the same one that comes with the new Eleaf iJust 3 (which I hope to review next week).

The Eleaf Ello Duro is a 6.5ml capacity tank (with the pre-installed bubble tank) that features a convenient top-filling system and adjustable bottom airflow.

The first thing I noticed about the new Ello Duro was that the drip tip and the glass section matched the color of the tank as well as that of the Lexicon mod, for a “matchy-matchy” look. I was a bit disappointed to see that the bubble glass was actually plastic, but the good news is that you have a classic glass section included in the kit, if you want to replace it.

Unlike the original Ello tank, or the Ello TS that cam e with the Eleaf Tessera, the Ello Duro comes with two different styles of coil-heads which feature metallic mesh, instead of the conventional wire coils. The pre-instaled one was rated at 0.15Ω and the spare one in the box at 0.20Ω. The texture of the mesh was also visually different, but I can’t say that I noticed a considerable difference in performance. They both vape the same way.

I’ve been using the 0.15Ω for a week and a half now, and it’s still going strong. Granted I’m currently vaping a fruit mix that’s very light on sweeteners, but still, I’m very happy with the coil-head so far. The flavor is above average, and the vapor production is amazing, especially at higher wattages.

All in all, the Eleaf Ello Duro is a nice tank to have in your arsenal. Is it my favorite atomizer of all time? No, but I’m not really a big fan of tanks, and for a bundle atomizer, it’s actually better than I expected. Plus, it offers vapers a chance to try mesh coils, which I for one had not had the chance to do before reviewing the Duro.


As a kit, the Eleax Lexicon is great value for money. You get an advanced mod packed full of useful features as well as a great sub-ohm tank, for around $70, which is not bad at all.

Taken separately, the Lexicon mod looks impressive, with its flawless paint job and pulsating LED lights, but it does have some issues (at least my unit does). The fire button sometimes doesn’t work properly, and the power ramp-up takes longer than I expected. Still, it’s a solid device, one that I’m glad to add to my collection.

As I said, the Ello tank is an above average tank which not only works great and is convenient to use, but also introduces mesh coils.
