Innokin Coolfire Z60 Kit first look

Innokin have updated their Coolfire range with the new Coolfire Z60 kit which features an all new Zlide tank which now has top airflow to avoid the age old leaking problem. They have also released an innovative new dual mesh coil to complement their ‘Coil +’ and ‘Refresh’ modes built into the mod's chipset.

  • Dimensions: 35.73*27.02*119.45mm
  • Tank Capacity: 3.5ml / 2ml (TPD)
  • Coils: Compatible with All Z-Coils
  • Resistance range: 0.2Ω~3.5Ω
  • Battery mAh: 2500mA/3.7V 7.77Wh
  • Minimum / Maximum Wattage: 6.0W~60W
  • Minimum / Maximum Voltage: 1.0~7.5V
  • Thread: 510
  • Body Material: PC and ABS
  • Charging Current: 5V/2A


I’m glad to see that Innokin have stuck to their environmentally friendly packaging with an all recyclable paper based box and wraps, the Z60 kit is still well protected and survived courier abuse, mine arrived with signs of it being lobbed around but everything was perfectly intact and unscathed.

Innokin Coolfire Z60 Kit unboxing

Innokin have included a generous bundle including the Z60 Mod, Zlide tank, two different Z Coils, two different drip-tips, a spare glass piece, a high quality charging cable, spare seals, and the instruction manual/warranty card.

The Z60 kit looks and feels pretty old-school but features modern innovations with Innokin’s chipset and the new Zlide tank which is a traditional structure but now has top airflow along with a new ‘Duo-wire’ coil all bundled into a pretty compact kit.

The size is 35.73mm x 27.02mm x 119.45mm which is quite impressive considering it has a built in 2500mAh battery and a colour screen. Weight wise; it comes in at 198g which is quite weighty but that’s a feature I like with Coolfire kits as they always have a sturdy, quality feel to them.

The styling is quite minimal and classy with its two-tone zinc alloy body and the Zlide tank matching the top section colour. It has been well sculpted and feels ergonomic with its barrel grip and protruding screen and control face which is comfortable whichever way you hold it.

The 510 connection on the mod will take up to a 25mm tank but a 24mm suits it best, it is raised a hairs width to prevent atty-rash which is always welcome. The base has a physical on/off switch, this turns the mod completely off which is better than standby in my opinion and is perfect for travel or storage. The switch is a little fiddly but this makes it harder to accidentally knock the switch.

The branding is discreet and minimal with the official bumf on the base and ‘COOLFIRE Z60’ on one side, the Zlide tank is even more discreet with embossed branding.

Innokin Zlide Tank

The Zlide tank looks completely different to the old version, the stand out difference is that the cage design has gone so the glass is fully exposed but this allows for a bubble glass version and that alone makes it more handy, but the other subtle visual difference is that it now has top airflow which makes the new Zlide tank an instant winner as it is near leak-proof and more trustworthy.

The airflow adjustment ring is suited to RDL and MTL with an elongated tear-drop slot, it closes off to a very tight MTL and opens up to a fairly restricted DL draw. If you are after a loose DL draw, you won’t achieve it with this tank, but the RDL draw is spot on and the MTL range will suit pretty much all MTL users.

Innokin Zlide tank coil change

To fit or change the coil, you need to remove the tank and unscrew the base, once removed the coil simply pulls out. To fit a new one, you need to align the two flats into the matching slot and push it in then screw the base back on, overall this is quick and easy to do.

Innokin Coolfire Z60 Kit coils and drip tip

You have two different coil options and thankfully Innokin include two different 510 drip-tips for MTL and RDL, the two included coils are:

  • 0.6ohm DuoPrime Z-Coil 9-13watts (MTL)
  • 0.3ohm Z-Coil 30-40watts (RDL)

The 0.6ohm coil is preinstalled and is currently the only one that features the ‘DuoPrime’ feature but that for me is the important one to feature this as generally it is the MTL coils that need an improved lifespan as the lower ohm ones tend to last ages anyway.

The concept is quite interesting and makes sense to keep an even e-liquid delivery to the mesh and should in theory pull the e-liquid through during and after each vape. Testing will see if it works as promised, more on that in Performance.

That aside, the Zlide is fully compatible with the full range of Z-Coils:

Innokin Z coil selection

As the name suggests, the Zlide tank features a top slide open filling hatch, simply slide it open in the direction of the arrow to reveal the fill port. As with pretty much every top-fill tank, the drip-tip can get in the way for chubby bottles but 10ml bottles are a cinch to fill it up mess free.

The Z60’s chipset is quite limited and lacks a lot of features DIY tank users seek such as TC (Temperature Control) and preheats, and I would say it is aimed at stock coil users but is perfectly matched for the Zlide tank and Z-Coils, especially with the superb Coil+ and Refresh modes.

  • 3 x Fire – turns device On/Off
  • Press and hold Up and Down buttons – enters main menu (Up/Down to navigate and Fire to confirm)
    • Coil+ = automatically refreshes the coil after each vape
    • Wattage = manual variable wattage but turns Coil+ off
    • Refresh = manually refresh the coil by pulsing a low wattage (set time or user select time)
    • Cut off = set the time of fire timeout (3 to 18 seconds)
    • Screen = set the time of screen cut off
    • Back = exits to main screen
  • Press Fire and Down – locks adjustment buttons
  • Press Fire and Up – puff counter reset and device info (Ohms/Battery status/Voltage)

This mode is set by default and I really recommend that you leave it in this mode as it works an absolute charm and is one of Innokin’s best innovations. In basic terms, it simply pulses the coil at a very low wattage to clear the coil of gunk and draws e-liquid through for the next puff, it works well and has definitely increased the coil lifespan on previous Innokin devices that also has this feature (Sensis and Z80 etc.).

You notice the benefits more, especially towards the end of the coils lifespan where you begin to notice a burnt taste by going to the REFRESH option and manually refreshing the coil a couple of times, you clearly notice the next puff is improved and generally the burnt taste vanishes for a short time. This is at the extreme end but just trust that this is going on in the background every puff from a new coil and throughout its lifespan, hopefully that made sense.
(This mode works on all Z-Coils)

Innokin Coolfire Z60 Kit with juice


I started off with the preinstalled DuoPrime 0.6ohm Z-Coil (9-13watts) and it didn’t take long to impress me, the flavour is superb but you notice that the coil is perfectly primed for each draw and fully saturated when you chain vape. I preferred the draw with the top airflow as it seemed smoother overall, and the airflow control gave me the tightness I prefer for MTL. The 0.6ohm coil is generally much lower ohms than I am used to for MTL but it still uses low wattage (I ended up at the top end of 13 watts) which makes it ideal as you appear to get a more saturated vape from it but with a very long battery life.

So I was very happy with the vape quality, but it was the lifespan that pleased me the most. I properly abused this coil and hammered it with constant chain vaping and used it for over ten days and I couldn’t kill it! I even tried over sweetened nic salts and it handled those easily which made it the best Innokin MTL coil that I have tried. No matter how the RDL coil performs, the 0.6ohm DuoPrime will be my coil of choice for this kit.

Onto the 0.3ohm Z-Coil at 35watts, I have used this coil many times before in the Z80 kit so it was no surprise that this offers a superb DL vape, but it was the first time I used it for RDL due to the new Zlide tank’s limited airflow, but I was in my element and enjoyed more than in full DL for some reason, the flavour came through a lot more and the Coil+ kept the coil fully saturated every draw. I didn’t test the coil for as long as the 0.6ohm as I already knew it lasts weeks as long as you leave Coil+ on.

Battery life; with the 0.6 DuoPrime coil it lasted me days! Well I would say a good two days of normal use and you can always trust it for a full 24 hours away. I tended to charge it up every forty eight hours regardless, obviously the battery life was less impressive with the 0.3ohm Z-Coil at 35watts, but it would comfortably last a full working day and into the evening.

Charging time was pretty good as it charges at 5V 2Amp and took around two hours from flat. Considering it is 2500mAh, that’s pretty decent. The only downside was the lack of battery charging status such as percentage or time remaining.

Compared to Coolfire Z50 and Z80

I’m torn, if I’m honest, as I am in love with the Z80 but I prefer a bit of bling to my vape kits and I tend to go for external batteries so I can simply swap a battery over rather than wait for charging, but the Z60 wins on a couple of features. Firstly, and possibly the most important, is the new Zlide tank and its top airflow which was truly leak-proof, I never experience a single drop making its way through to the top and it is perfect for throwing into a bag with confidence you’re not going to find a puddle after a couple of days. The other thing (which is transferable to the Z80) is the new 0.6ohm DuoPrime Z-Coil which is the best MTL coil I have experienced from Innokin.

Innokin Coolfire collection

Style wise; personally, I don’t find the Z60 as attractive as either the Z50 or the Z80, but that might make it more appealing to those that prefer a more discreet looking kit. The Z50 is pretty much redundant now though due to the old coils and lack of Coil+/Refresh, and the Z80 is more suitable for full on DL vaping, so the Z60 finds its place as my go to Innokin MTL kit.

Innokin Coolfire Z60 and tank


The Coolfire Z60 and new Zlide tank kit has old-school mod and tank appeal, but with modern features and, most importantly, a modern vape quality with longer lifespan coils. The compact size, on/off switch, and huge 2500mAh internal battery make it a great travel or out and about kit for RDL and MTL alike, but for me the new DuoPrime 0.6ohm coil make this kit the best MTL option I have experienced from Innokin so far. The looks aren’t my cup of tea but I don’t dislike it either, it’s nice but no Cameron Diaz.


  • Impressive 2500mAh battery
  • Top Airflow Zlide tank
  • All-new 0.6ohm DuoPrime coil
  • Compact and ergonomic
  • Coil+ and Refresh are invaluable
  • 2Amp fast charging
  • Proper MTL to RDL airflow
  • Generous bundle
  • Top-fill


  • No DIY options

The lack of DIY features make it better for those that only use stock coils as it makes it less complicated to use, so that’s your call.

Final Thoughts and Score

The Z60 is a mixed bag for me personally, I don’t ‘love’ it nearly as much as the Sensis or Z80 as it looks a little bland to me, but that said, I do like it and the new features, huge battery, compact size and new coil of the Zlide tank won me over to make it the best Innokin MTL device so far.

Score: A strong 9/10 – Generation Z

My background is Engineering and Professional Photography. Mostly from POTV users knowledge I learned so much about pretty much all styles of vaping and equipment, Cloud Chasing, Squonking, Mouth To Lung, Direct To Lung, Pods, Mechs, Rebuild-able tanks and atomisers etc, and have experience with many many devices and atomisers, it's become a hobby and enjoy trying out the latest gear. I like to think my reviews are plain speaking and informative without getting too technical, if I have to resort to reading the manual then I don't consider it user friendly!
