Joyetech ESPION SOLO Design Features & Usability
Espion Solo Box Mod
The name implies that it is a “refreshed” Espion with a “Solo” (single) battery.
Its ergonomic shape is tall and relatively narrow “rectangular” box with a half-cylindrical battery-cover door and other vertical edges just slightly rounded. This helps in comfortably holding it in your palm. The riffled-designed sides allow no-slipping fit in your hand.
Its battery-door’s shape design, with four magnets, doesn’t allow any door-play.
Besides the included 21700-battery (remove the insulating sticker from its bottom, at first use), a 18650-battery can be used with the included silicone adaptor. It carries a spring-loaded 510-pole connector and takes up to 25 mm-diameter atomizers.
On the front face side
- a 1.3inch touchscreen display
- a micro-USB port
- a large “Fire” button, with its edges curled-up at the sides of the mod
- a “Function” button for locking/unlocking the touchscreen
The touchscreen display
It’s a 1.3inch bright and clear B&W OLED touchscreen display, which is particularly responsive. Combined with an easy-to-use operating software-interface, it is convenient to make selections/adjustments with just your thumb. Either right-handed or left-handed.
Simply swipe the screen left or right to view the selections available and tap for adjustments. Mod turns on/off by 5 fire-button clicks. The touchscreen locks by clicking any button. For unlocking, press the function button.
The touchscreen display continued
On the main unlocked screen (either on power or temperature mode) you directly adjust wattage/temperature by tapping the up/down arrows. Then, swiping to the right reveals the left screen. Which is just information on the selected settings. Swiping to the left reveals the right screen of the operational menu. But, when you keep pressing the function button, it also scrolls through the modes.
Expanding the various selections on the screens, you go back by swiping to the right. By pressing fire or function buttons from any screen, you go back to the (locked) main screen. Click the function button twice to turn the screen on/off (stealth mode) for battery saving.
Note: Remove the screen’s protecting film with your fingernail, for experiencing maximum touchscreen’s responsiveness.
It is equipped with Power/Bypass/TC (Ni, Ti, SS316) and TCR (with 3 storable values) operation modes. In the modes-selection screen, an RTC “mode” is also included, with a Real Time Clock just inserted in the screen of Power mode. Either as an analog or as a digital clock display (selecting “point” or “number”, respectively, on RTC selection menu).
Swipe the screen to the right for checking your adjustments or to the left for entering the function-menu with MODE, SET, INFO, EXIT options. Tap icons to enter. Move down the SET screen to select PREHEAT for adjusting POWER and cut-off DURATION. In TC/TCR modes, tap SET for locking resistance and power.
When the mod is off, a fire-button click shows the clock:
Operation Modes Continued
Setting the clock is self-explained: first set the “hour”, then press the right arrow of the “hour”-frame to move to “minutes”/“year”/“month”/“day”.
Wattage change is performed at 0.1-watt increments below 20 watts only.
It also allows pass-through operation (vaping while charging), but it gets too hot when charging it with a 2A smartphone fast-charger. Very soon the “device too hot” message appears on the screen and the mod won’t fire-up (overheating protection).
Short-circuit, no-atomizer, weak-battery, low-power, low-resistance, over-charging, over-current, over-discharging, reverse polarity, puff cut-off, over-heating. Puff cut-off protection turns the mod off.
2A quick-charge. Use high-rate 21700/18650 cell (CDR>25A).
ProCore Air Clearomizer
Its name insinuates an airy clearomizer. It consists of five parts. It can easily be cleaned under running water.
It adopts the push-to-open top-filling design for easy replenishing the tank “on-the-go”.
The 4.5ml tank version is equipped with a chimney of noticeable height. This implies that it provides some “manipulation” of the produced vapour, targeting to flavour’s integration.
ProCA (0.4ohm) coil-head
It is a newly added coil-head in the ProC-series, made of Kanthal wire. It can be powered at a 40-80W range, offering a balance cloud/flavour experience at 55-65W.
Also, check for other ProC-series compatible coil-heads.
For replacing coil-head, unscrew atomizer’s base, taking advantage of airflow ring’s stopper for a steady grip. Turning the tank upside-down, you can replace coil-head with liquid inside the tank, if liquid doesn’t exceed the chimney’s height.
Joyetech ESPION SOLO Performance
As a single 21700-battery mod with a half-cylindrical battery-cover, it sits comfortably even in a small palm. It is not light-weight with the battery inside, but its weight gives a feel of holding a quality device. Its paint finish is excellent.
The battery cover is smartly designed. When removed, fully exposes the battery for easily removing it. Its 4 magnets are far back to its sides to not allow any door play. For easily removing the battery cover, just pull it out from its upper side only.
A 20700-battery can also be used.
Espion Solo Continued
The fire button is big, stretching out across the front-side of the mod and slightly around the sides, where it is also active. It doesn’t lock, so you have to turn the mod off to put it in your pocket. Ramp-up time is very short.
The screen is bright for being readable in daylight (not under direct sunlight, though). Touchscreen’s dimensions are the smallest possible for easy touchscreen operation. With its clever screen layout, it provides maximum usability with just your thumb. It is very responsive if you remove its protective film.
Note: Selecting to operate the mod in TC-SS mode with the included ProCA Kanthal-wire coil-head (a situation usual in case you don’t know the wire material of a coil-head). The “PROTECTION” message appeared on the screen substantially delayed the first time, followed by automatically switching to power mode.
It’s an airy sub-ohm clearomizer with a very wide wattage range of its included ProCA coil-head, optimized for covering the demands of cloud and flavour chasers.
The large size of the two opposite-positioned airflow slots of the bottom airflow ring, in combination with the large air-channel of the wide-bore BVC coil (6mm-diameter) of the ProCA coil-head, targets more to substantial vapour production with DTL vaping. But, it can also be adapted for loose MTL vaping.
ProCore Air Continued
The ProCA coil-head presents an extended lifespan. It’s a very fast liquid-saturated coil-head. It’s more suitable for 70/30 VG/PG liquids at 55-65W, for delivering flavorful clouds without over-flooding leakage from the airflow ring (better fire it for at least 2-3sec under intense DTL draws).
The spare black Delrin 810-drip tip is more suitable for cooler vapour with long airy DTL puffs.
With MTL vaping, irrespective of the wattage or the included drip tip used, accumulation of vapour’s condensation soon appears underneath the drip tip. To somewhat reduce the effect, just elongate your draw after releasing the fire button.

The Joyetech Espion Solo is a rock-solid, ergonomically hand-feel regulated box mod. With a very good build quality and very easy operation due to its particularly responsive touchscreen and its self-explained interface software (easy to use menu).
It also stands out due to its small size for a 21700-battery mod, its fast ramp-up time, it’s responsive -on its sides- large fire button, its tight-fit battery cover design (no battery-door play). It also takes up to 25mm-diameter atomizers.
The ProCore Air clearomizer is best suited for DTL vaping, providing flavorful clouds.
I am not in the vaping business. I found vaping as the escape door from my 25 years of smoker’s imprisonment. It just took me four days of attempting to totally get out of it, thanks to the appropriate –for me- “equipment” (includes e-liquids). Now, vaping “equipment” has become another one of my fields of interest, for helping others to discover, on their own, their personally appropriate “equipment”.
I am a hands-on enthusiast… by genes. I am triggered by everything that evokes any data already stored in my knowledge base, been a Physicist and an Electronics Engineer (for more than 35 years). I am intrigued by everything new that my knowledge-filter considers interesting enough to be analyzed for entering into my memory compartment. That’s why you will find me open-minded and out-of-the-box thinking. I have an urge for unfolding hidden “pictures” of design thinking on everything man-made.
