Unicorn 50W Mod Review
Pegacorn? Unisus? I’m not sure what the heck is going on with the logo. What I do know is this box mod is rocking dual 18650 cells and kicks out a purported 50W and features a touch sensor. Are these features grounded in reality or mythology? Let’s find out.
The Unicorn 50W box mod reviewed was provided by Electhinker.
A Mythical Creature
Unicorns are cool. Pegasuses?… Pegusii?… what the heck is the plural of Pegasus? Anyway, this box is rocking a winged, horned horse. That’s pretty cool, right? Right. The subject of this review is a dual 18650, variable wattage, 50W box mod featuring a touch sensor (more on that later). Graphics and mythology aside, let’s take a closer look at the Unicorn.
The Packaging and Included Stuff
The Unicorn mod arrives in a plastic clam shell box with some snazzy branding. The stuff includes a user manual, a USB charging cable, a dual-headed screwdriver, and the vaunted certificate of quality assurance. Boom!

The Unicorn box mod is inexpensive… and it feels inexpensive. Although this box mod checks in at >$50, it does have some redeeming build qualities. The Unicorn is rocking a magnetic battery door, an OLED screen, a lightweight aluminum body, and an adjustable 510 connector. To quote a vaping luminary: “not too shabby”.
However, not everything is magical about the Unicorn’s overall construction. While the buttons are responsive and have a nice tactile “click”, they exhibit a lot of rattle. The battery door slides down rather lifting off of the device, as indicated by the helpful down arrow graphic. Be advised, setting the Unicorn down on a metal surface will likely result in the battery door being left behind when you subsequently pick the device back up. In all other situations, the battery door is quite secure and slides on and off very smoothly.
The 510 connector on the top of the device is adjustable using a small flat head screwdriver – raise the 510 pin by turning it counter-clockwise, lower it by turning it clockwise. The top of the connector housing sits nearly flush with the top of the mod. The front of the device features a firing button above the OLED screen; the wattage up and down buttons below. On the bottom of the mod you will find the USB connector and 18 vent holes. The batteries in the Unicorn may be charged by connecting the supplied USB cable to the device and an appropriate power source. The back of the device, below the touch sensor, has some sort of soft plastic material inlaid into the chassis.
In hand, the Unicorn is a bit ungainly due to its dual battery form factor. Additionally, the edges of the Unicorn’s shell are rather sharp, rendering the device not terribly comfortable to handle for extended vaping sessions. The touch sensor, however, is very conveniently located. It feels very natural to fire the device via the touch sensor using my index finger (again, more on the touch sensor later).
The inside of the Unicorn is a tidy looking affair. The battery tray features labels indicating the proper battery orientation (positive side towards the 510 connector for both cells). Note the strategically placed holographic stickers – these stickers conveniently cover improperly stamped battery polarity markings. Either the plastic surround was intended for another device which uses batteries in series rather than parallel or it was just a manufacturing snafu. If not for the stickers, the potential confusion regarding battery orientation could have led to the premature demise of the mod. It should be noted the inside of the battery door also depicts the correct battery orientation. The battery contacts are fixed on the negative side and have some play on the positive side, allowing the fitment of various 18650 cells (I did not try button top batteries but all of the flat tops I tried fit with no issues). Also found inside the device is a “handy” battery removal ribbon. Handy is in quotes because A) it’s too short and B) it separated from the device the second time I attempted to remove the batteries. Not awesome.

I hadn’t intended to find out what lurks beneath the plastic surround piece inside the device. But, hey, for you folks? Let’s see what’s going on under the Unicorn’s hood.

I was expecting a mess of hot glue – so, the lack thereof was a pleasant surprise. However, the wiring is composed of some pretty small gauge stuff and some of the solder connections are, well, messy. All in all though, the guts of the Unicorn are fairly clean and well done. How well they survive over time remains to be seen.
Riding the Unicorn
Now that we’ve given the Unicorn a thorough physical examination, let’s take a look at the function and performance aspects.
Function first – after inserting a matched pair of high drain 18650 batteries, the Unicorn is brought to life with five properly timed successive clicks of the fire button. Upon successful completion of the button presses, you are greeted by the OLED screen displaying “Unicorn”… lest you confuse this winged beast with another mod, I guess. Clicking the fire button five more times in succession will power off the device.
The Unicorn, like many devices which use a DNA-style display format, shows the current power setting, battery life indicator, atomizer resistance to the resolution of 0.1Î©, and output voltage while firing. Please excuse the dubious quality of the following pictures – capturing the display with my iPhone was, um, challenging.
Adjusting to the desired wattage is accomplished, surprisingly enough, by pressing either the up or down buttons. Each single click will adjust the wattage in 0.1W increments. Holding down either button will continuously adjust the power level in whichever direction you have chosen. The Unicorn will accelerate the adjustment rate after passing 0.7W in either direction. Wattage does not “round robin” after reaching the minimum or maximum setting.
Pressing and holding the fire button and + (up) button will turn the touch sensor on. Subsequently, pressing and holding the fire button and – (down) button will turn the touch sensor off. Pressing and holding the + and – buttons will lock or unlock the Unicorn.
Okay, so how does the Unicorn perform? Actually, quite well. For the purposes of this review I used an Eleaf Lemo built to 0.6Î© – according to my pretty darn accurate ohm meter. The Unicorn reads the atomizer resistance at 0.5Î©. So, pretty accurate.
The Unicorn outputs voltage very accurately. It steps down the voltage and maintains a variance of around 0.2V according to my inline voltmeter. I was really (pleasantly) surprised at the accuracy of the board used in the Unicorn. From lower power all the way up to 50W, the Unicorn was playing no tricks – it really is putting out the power it says it is putting out. A lot of variable power mods on the market today can’t say the same.
I’ve been using the Unicorn for a couple of weeks now and have absolutely no complaints about the consistency and performance. I’ve experienced no odd behaviors, no glitches, no bugs… nothing but rock solid, predictable performance. Battery life is exceptional with two 18650 cells. On a related note, the Unicorn drains both cells at nearly identical rates. Pulling the batteries out and measuring their voltage periodically resulted in almost identical drain every time. At most, there existed a 0.1V difference between the batteries. Pretty dang good.
Remember the touch sensor? Yeah, maybe you should forget it. The only real issue I experienced using the Unicorn was the propensity for the device to auto-fire when the touch sensor was enabled. I ran into this problem not long after starting the test of the Unicorn. I quickly disabled the touch sensor and never re-enabled the feature. To be fair, I experienced a similar issue with my old Pioneer 4 You IPV2’s touch sensor. It really is a shame because the Unicorn’s touch sensor is perfectly positioned on the device. I’d suggest to the manufacturer to ditch the touch sensor and move the fire button to the sensor’s current location.
All things considered, the Unicorn is a very good performer.
The Unicorn, while fairly cheaply constructed, is a surprisingly good performer. I can overlook the build quality and ergonomic deficiencies in light of how consistently and accurately it powers an atomizer. Will it endure a long, chain vaping life? Hard to say… but, judging by the overall build quality, I’d opine this device is destined to be a throwaway mod at some point in the not too distant future. But, given the price point and how quickly new devices are coming to market, I think the Unicorn is a lot of bang for the buck – I’ve used worse devices which cost more money. I have no problem recommending the Unicorn to a vaper looking for a moderately powered, accurate device which delivers all day battery power.
