Joyetech Espion Infinite with ProCore Conquer

Joyetech has jumped on the LED bandwagon and released a dual 21700 device complete with infinity mirror style LEDs. The Espion Infinite can utilize 21700/20700 and 18650 batteries with an adapter and is capable of firing up to 230W.

It comes paired with Joyetech’s latest sub-ohm tank the ProCore Conquer which has a 5.5ml capacity and uses the ProCore series coils.

The Good

Good build quality, outstanding battery life, centered 510, good power performance and excellent coils.

The Bad

Terrible small screen, poorly located adjustment buttons, lacking TC performance.

The Bottom Line

The Espion Infinite is probably Joyetech’s ugliest and least practical device to date. Unless you’re a fan of the infinity mirror style LED lights, which seems to be the main reason for this device’s existence. The only saving grace is it is a dual 21700 mod with excellent battery life, and the included tank uses the ProCore coils.

Joyetech Espion Infinite

The Espion Infinite is a dual 21700 device which steps aside from the Joyetech’s traditional Espion styling and follows the trend of RGB LEDs.

However, we can’t go into too much detail about the LEDs until we talk about the screen.

The Espion Infinite has an extremely large plexiglass front, and at first appearance, you think wow this is going to have an awesome large screen.

Nope, once you fire the device up you soon realize all of that real estate is just to house to sets of inset LEDs, which cover the circumference of the glass to create a 3D infinity mirror effect. Then you notice they only left space for a measly 0.9inch display in the center.

If the proportion of the screen to the device was not bad enough, they’ve also tried to cram too much detail in with the smallest fonts and imbalanced colors – making it possibly the worst screen I’ve seen on a device this year.

The most irritating aspect of this, is on previous Espion devices, including the touchscreen Espion Solo the display was not only larger and brighter but far easier to use.

I understand that they wanted to use two sets of LEDs (which I will go into detail about later), but sacrificing practicality is not usually Joyetech’s method, and that’s what is most disconcerting.

Joyetech has also moved the +/- buttons to the topside of the device. This makes it a little cumbersome to adjust, especially with one hand as it’s a large device. I also have my reservations about how close they sit to the centered 510 connection.

The Infinite is capable of housing tanks up to 30mm, but if you end up with a leak from the tank, the juice is heading straight for those adjustment buttons. Joyetech has most probably sealed the unit beneath the buttons, but I still think it may not hold up over time, and is another poor design choice just to cater for those 3D LED lights.

Style

The one thing I’ve always liked about Joyetech’s devices, especially the Espion line is the reserved, almost elegant styling.

So I’m not sure what happened here with the Infinite, but it seems they have been too keen to follow other manufacturers into the realms of flashing LEDs, that they forgot the roots of their Espion designs.

There are still the usual characteristics of nice brushed metal accents and a large branded fire button, but the color options available don’t seem to compliment the brushed metal, and I think i’ve said enough about the screen!

Joyetech Espion Infinite

Build Quality

The Espion Infinite is an incredibly sturdy and solid device. I know we say that about most dual battery mods nowadays, but it’s even more noticeable with this one.

All aspects of the device from the 510 connection, fire button and battery door are thoroughly constructed.

The fire button is the same as on the previous Espion, large, tactile and incredibly easy to fire.

The battery door features clear orientation markings, it sits flush and there’s no sign of rattle. The only downside with the battery compartment is when using 20700 instead of 21700 you can feel and hear the batteries shift around – but this seems to be the case with most multiple battery devices at present.

Portability

The Espion Infinite is a bulky device measuring in at 140.5mm x 49.5mm x 33.0mm.

It also weighs 172g without batteries, so not the lightest of devices, but I guess that is to be expected with a dual 21700 mod.

Innovation

While this might be a particularly unique device for Joyetech and is possibly the first to feature LED lights of this style. It certainly does not have any innovation to it.

Features7.5
Joyetech Espion Infinite

The Espion Infinite is capable of firing up to 230W and comes with Joyetech’s usual array of features.

That includes a full temp control suite supporting Ni, Ti, SS316, and TCR with 3 memory modes.

There also a preheat option, which allows you to enter the power and duration of the preheat.

Joyetech also incorporates their RTC mode, which is basically just power mode with a clock face on the display.

The Infinite supports 2amp charging and as previously mentioned supports 21700/20700 and 18650 batteries with the included adapters.

The usual safety features of reverse polarity protection, over-charging, over-current and over-discharging are all present.

This is a new proprietary chipset that Joyetech are using, so we’ll see if that brings any improvements in performance. It is also firmware upgradeable.

Operating

Joyetech has abandoned the mode button that we saw on previous Espion models, which makes the slightly Infinite less user-friendly.

However, it is a relatively straightforward menu system to get to grips with.

3 clicks of the fire button will bring up the menu system with 4 options, which a pretty self-explanatory. There are:

  • Mode
  • Set (settings)
  • LED
  • Exit

You can change the actual screen text and display on the ‘Set’ menu, with golden brown, blue, green, and red as color options.

LED LIghts

The main feature and I guess selling point of the Espion Infinite is the LED lights.

There are several lighting options, which can be configured in the ‘LED’ setting.

The lighting selections are as follows:

  • Moon: solid color (choice of several colors or set your own)
  • Fire: downward and upward movements changing color as it moves
  • Wheels: travels around the screen changing color
  • SPE3: multiple colors spin around the screen
  • SPE7: multiple colors jump around the screen while keeping a solid base color
  • Glow: fades in and out with varied intensities and colors
  • Morph: varied colors changes while the brightness stays constant

Choosing ‘Switch’ in the LED setting will allow you to either disable the LEDs are set there use to stay on, only on when the screen is in use or only during vaping use.

You can also adjust the brightness of the lighting in the LED setting.

Tank7.0
Joyetech Espion Infinite

The ProCore Conquer appears to be upgraded ProCore Air with a larger 5.5ml capacity, and slightly larger airflow.

It’s 55mm tall (including screw thread and cap) with a 25mm diameter, although this does protrude a little more due to the bubble glass which is included.

It comes in the same color as the Infinite mod and features a slide top fill design.

The tank is quite a knurly affair in its appearance, and one aspect which I really don’t like with this knurling is the spikey accents on the base.

When you remove the base from the glass, these parts protrude up from the base and are remarkably sharp, to the point where I actually think they are a little dangerous. I’m perplexed as to why Joyetech didn’t round off the edges, and again it feels like form over functionality.

Joyetech Espion Infinite

Refilling

The slide to fill mechanism on the top of the ProCore Conquer tank works well, just like with other ProCore tanks.

The fill port is nice and large, and I didn’t notice any leaking coming from the top of the tank during my use.

Joyetech Espion Infinite

Coils

The ProCore Conquer comes with two coils in the kit.

The first is the ProCA (0.4ohm) coil which is one of their original coil heads and has a recommended wattage of 55-65W.

The second is their new ProCD (0.15ohm) coil which is a reticular mesh coil (Kanthal) and has a recommended wattage of 55-65W.

The ProCore Conquer is compatible with any of Joyetech’s ProCore coil family, which I find to be a decent and reliable range.

Joyetech Espion Infinite

Airflow

The ProCore Conquer has two huge bottom airflow slots, which helps to make it an incredibly airy tank.

Unfortunately, with all that airflow comes a lot of noise. This is a seriously loud sub-ohm tank.

The AFC ring has some knurling to making it easy to grip, although that’s not really an issue as it moves far too freely in my opinion. It does also have stopping points at either end of the turn.

Performance7.5
Joyetech Espion Infinite

The Performance of the Infinite mod was pretty much what you’d expect from a Joyetech device.

The updated chipset only brought one noticeable changes over previous Espions.

The Infinite has almost instant firing in power mode. Joyetech claim it’s 25 milliseconds, all I can say is it felt ultrafast and par with other fast firing mods I’ve tried recently.

Wattage Mode

In wattage mode, the Espion Infinite is a solid performer. It hits instantly and feels very accurate on the power.

The pre-heat settings enable you to set the wattage and duration of the initial power and work properly.

As I’ve probably mentioned before, it’s a shame that Joyetech still doesn’t offer any power curve settings.

Joyetech Espion Infinite

Temperature Control Mode

I was hoping that with the updated chipset we might see some improvement in TC from Joyetech.

Unfortunately, its the same lacking experience as with Eleaf and Wismec devices.

The temperature setting is still a little too conservative, and it really does not play nicely with exotic coils. It’s often jumping out of TC mode for no reason.

The vape is a little smoother than their older devices, but no improvement over that of the Espion Solo.

Joyetech Espion Infinite

Battery Life

Battery life was excellent using the Infinite.

Joyetech actually sells the kit with two included Avatar Controls 21700 batteries which have 4000mAh mAh capacity each.

This setup easily saw me through a whole day of vaping, and nearly through a second at around 70-80W, that’s impressive.

Likes

  • Good build quality
  • Nice fire button
  • Good power performance
  • Centered 510
  • Fits 30 mm atomizers
  • Excellent battery life
  • Solid battery door
  • Fits 21700/20700 and 18650 batteries
  • Excellent range of coils

Dislikes

  • Tiny screen
  • Over the top LEDs
  • Position of +/- buttons
  • Sharp edges on base of tank
  • Lacking TC performance

Verdict

The best part about the Espion Infinite, in my opinion, is the coils.

Yep, that’s right I think the ProCore coils, especially the new ProCD mesh coil are perfect and produce excellent flavor with a decent lifespan.

The ProCore Conquer tank isn’t the greatest looking tank, and that spikey knurling on the base is a particular design flaw, along with the noisy airflow. That being said it is still a good performing tank particularly as part of an inclusive kit.

The Infinite mod itself doesn’t have any flaws when it comes to build quality, and it performs really well in wattage mode. I just really dislike what Joyetech have done with the design.

The tiny color screen is poor, and the LEDs takes up far too much real estate, it’s a sad departure from Joyetech’s usual classy styling.

However, if flashy lights and power performance is your thing, then the battery of life of dual 21700’s will undoubtedly be a huge positive.
