Joyetech Espion Solo Review – Hand Solo

From the looks of the Joyetech Espion Solo, it seems like Joyetech is going back to their roots. New single battery mods seem to be a rarity nowadays and it’s a good thing that Joyetech is mixing things up a bit with this new release. Compatible with both 18650 and 21700 battery cells, the Joyetech Espion Solo fires up to a maximum of 80 watts. The ProCore Air tank which comes bundled with the kit holds up to 4.5ml of e-liquid for even longer lasting vaping sessions and looks to be the successor of the esteemed ProCore Aries.
Let’s take a closer look at the Joyetech Espion Solo kit and see if it brings anything new to the table. Be sure to check the vape buyer’s guides for important information to take into consideration before making your purchase.

Manufacturing Quality

Anyone familiar with Joyetech mods will instantly recognize the Joyetech Espion Solo as a revamped version of their widely popular and critically acclaimed Evic Mini. While sporting a very similar form factor, the Joyetech Espion Solo makes a few changes over its inspiration, one of which is a much larger and rectangular firing button.

While I had no qualms over the original Evic Mini’s firing button, many vapers who have larger hands/fingers shared the same complaint that the firing button was too small and could be sometimes difficult to press due to its slightly recessed design.

The firing button on the Joyetech Espion Solo has been totally revamped as a welcome improvement. Now employing a large and rectangular firing button which is flush with the body of the mod, it’s highly tactile and clicky, offering a wonderful response whenever the mod is activated.

Aside from the changes on the design on the firing button, the Joyetech Espion Solo also uses an upgraded OLED screen with touch capabilities and a revamped user interface optimized for touch controls. The Joyetech Espion Solo tosses the old and tired up/down wattage buttons out the window and now opts for a single function button which is used to lock the device and also access the settings within the menu, creating a cleaner and sleeker design.

Speaking of the design, the Joyetech Espion Solo has that in spades. Forgoing the safe and plain design of the Evic Mini, the Joyetech Espion Solo is spicing things up with textured and ribbed panels located on either side of the mod, resulting in a better grip when holding the mod. Minimal and tasteful branding also accents the sides, while the chrome-like firing button features a 10th-anniversary limited edition engraving in celebration of Joyetech’s solid 10 years in the biz.

Just like the Evic Mini, the Joyetech Espion Solo uses magnets to hold the battery door in place. The magnets are strong enough for regular use, but one issue I had with the Evic Mini was the adhesive locking the magnets in place had a tendency to degrade over time. While it might not necessarily be the same for the Espion Solo, only time will tell if that’s the case.

Flavor Quality

One of the newer additions to Joyetech’s lineup of stock coil heads is the ProCA coil rated at 0.4 ohms uses a large single macro coil to effectively vaporize e-liquid evenly.

Optimized for use within the 55-65 watts range, it works perfectly in tandem with the Joyetech Espion Solo especially with the ProCore Air, achieving a great balance of flavor and vapor production while also doing a good job of preserving battery life.

The ProCore Air tank which is bundled with the kit uses a wide bore drip tip ideal for direct lung vaping, so if you’re looking for a mouth to lung vaping experience, it might be a good idea to take a look at custom drip tips as well as Joytech’s ProC1-S coil head which offers an exceptional mouth to lung vaping experience.

But when everything’s said and done, the ProCore Air tank is meant for direct lung vaping with its wide open airflow slots meant for maximum cloud production.

In addition to the standard variable wattage mode, the Joyetech Espion Solo also supports temperature control for all stainless steel, nickel, and titanium coil heads with a temperature range of 100-315 degrees Celsius. Temperature control feels like on the Joyetech Espion Solo feels like a big upgrade over the Evic Mini thanks to the fine-tuning that Joyetech has done to their firmware over the years. Variable wattage doesn’t skip a beat either and ramp up is quick with little to no delay.

The Joyetech Espion Solo also has a real time clock which can be accessed at all times, even while vaping. Bypass mode is also available for vapers who would like to practice their coil building skills but still have the safety measures of a regulated device in play.

Lastly, adjustable TCR is also an option for those who aren’t satisfied with the performance of stock temperature control and would like to take complete control over how their mod vapes.

Ease of Use

While the removal of the up/down wattage buttons does increase the learning curve of the Joyetech Espion Solo a bit, that doesn’t mean that the revamped navigation system is difficult to learn.

The button for locking and unlocking the device has finally shifted from the firing switch to a dedicated function button which is great for those who always accidentally fire their device when trying to switch it off.

The OLED display feels responsive enough that making any changes to the settings doesn’t feel like a chore. While it might not be the most ideal touchscreen setup due to the small display, it still does the job pretty well and manages to compress a new way of menu navigation within a much more compact mod.

One of the biggest advantages of using a device like the Joyetech Espion Solo is that not only do you get pros of having a small and compact device, but you get the full potential battery life possible.

Not only is the Joyetech Espion Solo compatible with 18650 batteries that go up to 3000+mAh in available power, the mod also supports 21700 batteries meaning you can get up to 3700mAh on a single charge.

In addition, batteries are fully swappable, so if you hate charging your mod on the go, getting a couple of spare batteries, charging them at home and taking them with you is always a viable option.

Having said all this, the Joyetech Espion Solo does great on a single charge for light to moderate vapers, but those who chain vape often might be looking for a bit more longevity which can be achieved by easily swapping out the battery.

Overall Experience

If you were a fan of the Evic Mini, then you’ll definitely find many things to like about the Joyetech Espion Solo. The new and improved display, as well as the support for larger 21700 batteries, are always a welcome addition to any feature set.

While the lack of up/down buttons and the shift to touchscreen navigation for some, the device is still relatively simple to operate and is a great choice for vaping veterans or newcomers alike.

If you want something extremely simple, check out the Kandypens Rubi and if you are looking for the best mod style kit to start with we recommend the SMOK Procolor.
