Innokin Coolfire Z60 Zlide Top Kit Review

Richard Winter Mods Leave a Comment


Welcome to our review on the latest addition of Coolfire kits being released from the renowned Innokin camp…the Coolfire Z60 Zlide Top Kit.

Oh blimey, where do I start!? The Coolfire series of kits have been around for many years and continue to go from strength to strength. For me personally, my vaping journey started back in 2015, my first ever vape device, the Coolfire 1 with the iclear 30s. I still have two of them and yes they both still work.

Innokin later released the Coolfire 3 (I don’t think the Coolfire 2 existed) which I never owned as it was quite a bold statement with the design resembling a hand grenade (the less said about that the better).

Fast forward a couple of years, I moved onto the Coolfire IV (4) with the I Sub Tank, another really good device and kit. I still have a few of these too, all of which also still work.

My next Coolfire purchase was the Coolfire Z80 kit with the Zenith II Tank, which I reviewed back in 2021 and really loved. Strangely enough, I missed out on the Coolfire Z50 with the Zlide Tank, which looking back was a big mistake as this was a really popular product and sold in the millions.

I couldn’t resist adding a photo showing the Coolfire range I own just for nostalga!

Innokin are continuing with the Coolfire name and have taken what was already a proven product and hit us with the all new Coolfire Z60 with a brand new Zlide Top Tank. The beauty of this kit is it appears to have taken some of the best bits from their Kroma 217 Mod (Coil+ and Refresh), which we reviewed back in 2021.

Not only that, the Zlide tank which was part of the Z50 and Adept mod kits, which has to be one of the best MTL tanks around, is now redesigned with Top airflow. It still accepts all the Z series of coils but now includes their DuoPrime technology in the brand new 0.6 ohm pre-installed coil.

Still maintaining that traditional styling of the Coolfire range of mods that we’ve come to know and love, the Coolfire Z60 with the Zlide Top tank surely can’t fail to be one of the best MTL kits around.

Overview

Innokin Coolfire Z60 Zlide Top Kit in Silver and Purple

The Innokin Coolfire Z60 kit is a Mouth-To-Lung (MTL) and Restricted-Direct-To-Lung (RDL) device, powered by an internal 2500mAh capacity battery firing up to 60W. It’s essentially a variable wattage/variable voltage mod but with the inclusion of Coil+ and Refresh technology.

Coil+ mode will automatically pulse your coil after each vape, effectively clearing residue and drawing e-liquid to the coil in readiness for your next draw. Refresh will revitalize your coil by heating it to 40% of your set vaping wattage to help saturate your wick.

It’s smaller than the Coolfire Z80 but still made out of high grade Zinc Alloy, achieving low weight and high durability with the robustness and quality we now come to expect from Innokin.

Incorporated into the mod is the Type-C USB charging port and a 0.96inch colored OLED display screen. A master switch is positioned on the base of the Coolfire Z60 mod to fully shut off the device instead of using the normal 3/5 clicks of the fire button.

Innokin Coolfire Z60 and Zlide TopTank with Z Coils

Coupled with the Coolfire Z60 is the newly updated Zlide Top Tank. It’s a slide to open top fill with adjustable single slot top airflow. It holds a maximum of 4.5ml (2ml EU version) with the option of purchasing a 3ml glass if preferred.

The Zlide Top Tank has a removable 510 drip tip and accepts the range of Innokin’s Z coils. Innokin’s DuoPrime coil technology has now been introduced in the Z coil range with the 0.6 ohm coil included in the Coolfire Z60 kit. DuoPrime is an inner and outer layer of mesh surrounding the wicking material that improves e-liquid saturation, flavor production and coil longevity.

Innokin Z60 Zlide Top Kit Colors

There are 7 different colors in the Innokin Coolfire Z60 Kit range; Purple, Blue, Gunmetal, Stainless Steel, Black, Pink and Red. The frame of the Coolfire Z60 comes in 2 colors; Black and Stainless Steel while the Zlide Top Tank comes in 4 colors that match the frame of the Coolfire Z60; Silver Grey, Gunmetal, Blue and Black.

Really nice to see Innokin including all of the above spares in the kit, it certainly gives you the warm fuzzy feeling that you’re getting your monies worth.

I know I’ve mentioned this before in my other Innokin reviews, but I have to point out again that the packaging the Coolfire Z60 kit comes in is made out of 100% recyclable cardboard. This also includes the spares which are housed in thick paper sachets.

Innokin Coolfire Z60 Zlide Top Kit Inside of Box

The packaging box is a folded lift to open lid with a cardboard insert housing the Coolfire Z60 device and Zlide Top Tank with the spares and manuals below. The outer surfaces of the box is plain buff colored with the internal color being blue. This box measures 115mm x 117mm x 45mm.

Innokin Coolfire Z60 Zlide Top Kit Box Front
Innokin Coolfire Z60 Zlide Top Kit Box Reverse

On the front of the box is a ¾ length photo sticker in the color of the included Innokin Coolfire Z60 Zlide Top. This includes a small list of the main features which then wraps around the side with a further smaller picture of the device and the written name of the color.

The reverse side of the box includes the package contents, an authentication sticker, the manufacturer’s details and the relevant safety and nicotine warnings.

Innokin Coolfire Z60 Mod Design and Appearance


The Innokin Coolfire Z60 is a Variable Wattage (6W-80W) and a Variable Voltage (1V-7.5V) mod, there are no temperature control options. Two further modes have been included, these being the innovative Coil+ and Refresh which we’ve seen in our others reviews of the Coolfire Z80 and Kroma 217.

Coil+ will send a short pulse of current to the coil after every puff/draw to increase the lifespan of the coil, while Refresh is a selectable option that will apply a short burst of lower power (40%) either manually or automatically to help improve any muted flavor from the coil.

Overall dimensions of the Coolfire Z60 mod are 75mm high (excluding the tank), 36.6mm wide and 27.2mm deep with the weight of the mod being 129 grams. It’s powered by an internal 2500mAh capacity battery and is charged via the Type-C USB port on the bottom front face of the Coolfire Z60 body, specified as 5V/1.7A.

Main Charging Display on Coolfire Z60

Charging time will take approximately 2 hours to fully charge the device. It does include a pass-through function so you can vape while it’s being charged. When placed on charge, the display will indicate the scrolling battery icon to indicate that the Z60 is charging.

Unfortunately, this charging display screen will extinguish after the screen cut-off period is reached. To verify the current charging status of the battery, you have to press the fire button to make sure its still charging. Equally pressing the fire button and + buttons together will bring up the numerical voltage value.

We’ve included a more detailed description of the charging status in the How do I Charge the Z60? section later on in this review.

Scrolling Battery Icon On Coolfire Z60

The battery icon on the top right of the main display screen will indicate the remaining battery charge level during use in 3 different colors:

  • Red: <20%
  • Yellow: 20% – 60%
  • Green: >60%

Made out of high grade zinc alloy, the Coolfire Z60 has a semi-matt two-tone colored surface finish. Interestingly, the ¾ length main body color continues on the base which appears to be a 1 piece construction. Equally, the ¼ top length of the body, which comes in a different color, again a 1 piece construction forms the top of the Coolfire Z60.

Side View of Silver and Purple Z60's

These two different color sections join together forming the overall body. Quite hard to describe but hopefully you will see what I mean from the photos.

On the top of the Coolfire Z60 is the centrally located gold plated spring loaded threaded 510 connector plate, be it slightly set back from the front of the device. This 510 connector is very slightly raised from the main body to protect the attached tank from scratching the surface of the mod. There are also cross cut lines on the plate to aid airflow under the tank.

The diameter of the top surface on the Coolfire Z60 is just under 28mm so tanks over this diameter will overhang.

Control is achieved by the 4th generation chipset and the User Interface (UI) is a 0.96inch OLED colored display. It’s located on the front of the Coolfire Z60 in-between the fire button and the +/ – buttons on a black matt transparent finger plate.

This screen is clear and crisp showing the vaping mode you’re in (Wattage/Voltage/Coil+), Screen Lock, Battery Icon, Coil Resistance, Puff Counter, Vape Duration and the Voltage being drawn while vaping.

Although the screen is not adjustable in terms of color or brightness, the numerical information is displayed in white and the display is bright enough to be viewed in most lights.

Firing the mod is carried out by pressing the circular slightly beveled button (9.8mm diameter) on the front of the Coolfire Z60 above the OLED display There are two smaller +/- bevelled buttons (5mm diameter) that increase/decrease the wattage/voltage and are used to select and scroll through the different menu options.

Innokin Coolfire Z60 Control Buttons and Branding

The response and feel of the buttons have a positive click and there is no button rattle. Ultra-fast firing speeds are achieved by the 4th generation chipset.

Innokin Coolfire Z60 Master On/Off Switch and Branding

Innokin’s branding is kept to a minimum with just the name of the device “COOLFIRE Z60” screen printed on the flat side in reasonable small font. The only other information printed on the body is on the base of the Coolfire Z60 which shows “Innokin” and “Capacity 2500mAh 9.25Wh 3.7V”.

Another great addition on the Coolfire Z60 is a recessed master on/off switch that sits below the flat surface of the base and fully shuts off the device.

Accessing the menu structure is achieved by using a combination of the fire button and the + / – buttons. More detail of the menus is described later on in the Functionality section.

With regards to safety features, the 4th generation chip provides the following prompts such as:

  • 3-18 seconds timeout (vape cut-off)
  • Low battery voltage (3.3V)
  • No coil/atomizer detected
  • Short circuit and low resistance cut-off.

All in all, the Innokin Coolfire Z60 feels solid, robust and very well built, something we now come to expect from Innokin. It’s pretty small, lightweight and feels very comfortable to hold and does have a stylish look to it.

Available in 7 different colors; Purple, Blue, Gunmetal, Stainless Steel, Black, Pink and Red, with the frame of the Coolfire Z60 coming in 2 colors; Black and Stainless Steel.

Innokin Zlide Top Tank Design and Appearance


The Zlide Top Tank is an updated version of the original Zlide tank that we saw on the earlier Adept and Z50 kits. While still boasting the great features and of course performance found on that tank, its airflow has now been changed and improved to a top variable airflow design.

Innokin Zlide Top Tank

Constructed out of stainless steel and Pyrex glass, the Zlide Top is 51mm tall including the drip tip. The 510 threaded pin that protrudes from the base of the tank is part of the coil and not the tank. The width of the tank is 24.5mm in diameter and the weight, including the coil is 69 grams.

Innokin Zlide Top Tank Sliding Top Fill Cap Reverse Side

The Zlide Top tank has an e-liquid capacity of 2ml (EU version) or a 4.5ml bubble glass (standard version) with the option of also purchasing a 3mm straight glass. It’s a top fill design incorporating a slide to open top cap. When opened, there is a silicone rubber seal enclosing the fill port opening, simply pass the tip of your e-liquid bottle through the seal to fill.

Indented into the sliding top cap is a small arrow that indicates the position and direction of travel to open the top cap for filling. The e-liquid fill port is a pretty decent size kidney bean shaped opening (8mm) so will accept the majority of e-liquid bottle tips.

A black colored 510 removable MTL drip tip securely fits into the top cap with 2 O-Rings ensuring it won’t fall out. Included in the kit is a spare 510 wider bore drip tip for RDL vaping.

Innokin Zlide Top Tank Airflow Ring Open

Innokin Zlide Top Tank Airflow Ring Closed

Improved airflow is achieved by the fully adjustable top located quarter turn airflow control ring. This ring is knurled to aid greater grip when turning as it does have a nice tight restrictive feel to it. The airflow opening is different to the usual Cyclops slot(s) in that it is a single slot. It’s very wide (20mm) and very thin with a graded scale measuring 1mm at one end to 2mm at the other.

The airflow can be adjusted anywhere from fully open for a RDL style to fully closed for a tight MTL vape style.

Innokin Zlide Top Tank Base Removed

Unscrewing and removing the bottom section of the tank anti-clockwise gains access to the Innokin push fit Z coils. The Coolfire Z60 accepts all of the Innokin Z coils and two coils are included in the Coolfire Z60 kit and are KA1 (Kanthal);

Innokin 0.3 and 0.6 Z Coils
  • Z 0.6 ohm coil: 9W-13W – DuoPrime Kanthal Mesh – MTL
  • Z 0.3 ohm coil: 30W-40W – Kanthal Mesh – RDL

These coils do NOT screw in but simply push in. Two flat indents on the coil locate into the two flat indents in the base of the tank section. Removal of the coil is again pulled and NOT screwed from the tank.

Innokin Zlide Top Tank Base Removed Showing 510 Thread On Z Coil

As with the entire range of Innokin Z coils, the threaded 510 connection to the mod is part of the coil and NOT the base of the tank. Every time you replace the coil you’re effectively using a new threaded 510 screw connector. Perfect in my eyes that if you cross thread the male screw, it’s only the coil that’s affected and not the tank itself.

Zlide Branding

Branding is minimal with the words “INNOKIN” and “ZLIDE TOP” etched into either side of the bottom section of the tank. Also the usual CE markings, along with “DESIGNED BY P.BUSARDO VAPINGGREEK” and “PLATFORM SERIES” are etched into the bottom of the Zlide Top base plate.

Innokin Zlide Top Tank Stripped Down in 6 sections

Stripping down the Zlide Top tank is straight-forward and disassembles into 6 parts including the coil and 510 drip tip for easy cleaning and maintenance. Lots of spare O-Rings are included in the kit if any on the tank get damaged or lost.

Overall I really am impressed with the machining of the threads and the quality feel of the Zlide Top tank. The top fill sliding mechanism works very well and the top airflow is now a great addition and very effective. Having the optional size Pyrex glasses in 2ml, 3ml and 4.5ml is very welcomed. Nice to see the DuoPrime tech is now included in the increasing range of push fit Z coils (0.6 ohm).

Innokin Coolfire Z60 Mod Functionality


The Innokin Cooflire Z60 mod uses a 0.96inch colored display to show all of the set parameters. Included on the 0.96inch colored display is all of the read-out information as follows:

Coolfire Z60 Screen Display
  • Battery level indicator: Color change bar
  • Wattage / Voltage / Coil+ selected
  • Wattage / Voltage levels
  • Lock / Unlock
  • A smaller Wattage/Voltage reading (opposite to what’s been selected)
  • Coil resistance reading
  • Puff counter
  • Vaping time reading

Changes to these parameters are carried out by sequential presses of the fire button and the + and – buttons.

Basic Operation

Master On/Off Switch on Base of Z60

Attention!: There is a master on/off switch on the bottom of the Coolfire Z60 that shuts down the mod. Ensure this switch is put in the ON position otherwise nothing will work.

  • Fire button pressed 3 times turns the device on or off (standby mode)
  • Fire button and + button shows battery charge, coil resistance and puff counter
  • Hold + button till display flashes, then press + button to increase the wattage or voltage
  • Hold – button till display flashes, then press – button to decrease the wattage or voltage
  • Fire button and – button will lock/unlock the device (fire button still fires)
  • + and – buttons together will enter the menu options

Menu Options

Coolfire Z60 Menu Screen Display
  • Coil+: Wattage or Voltage mode can be selected
  • Wattage: Standard power mode without coil+
  • Refresh mode: + or – button to select auto or manual refresh
  • Cut-Off: 3 seconds to 18 seconds
  • Screen: Timeout from 5 seconds to 180 seconds
  • Back: Takes you back to the main menu

While the Coolfire Z60 manual is pretty good in the description of the functions and menu’s, we’ve included a detailed description of all of the operations for greater clarity.

Powering up the Coolfire Z60

The Master On/Off switch on the bottom of the Coolfire Z60 disables the battery. In the Off position, the unit will NOT function. Switch the On/Off switch to the ON position before any operation can take place.

When you first move the switch to the ON position, the display screen will display “Click 3 X Power On”. Press the fire button 3 times and the Coolfire Z60 will power up and display the main screen settings.

Switching Off and On using the master switch or 3 clicks of the fire button will power up the Coolfire Z60 in the mode it was in prior to being switched off.

Increasing/Decreasing the Wattage/Voltage Level

Pressing the + or – button will have no effect in decreasing or increasing the wattage/voltage levels until you first hold down either the + or – button until the numerical power level flashes.

When the display starts to flash, release the button and then press the button again. This will now increment or decrease, depending on which button you’re pressing, the wattage in 0.5W increments or the voltage in 0.1V increments.

The + / – buttons do a round robin so when you reach the maximum, the next press will take you to the minimum value and vice versa.

Coil+ Mode

Coolfire Z60 Coil+ Wattage/Voltage Screen Display
Coolfire Z60 Coil+ Wattage Screen Display

Press the + and – buttons simultaneously to enter the menu mode. Scroll down to “Coil+” and press the fire button. This will enter the sub menu of WATTAGE or VOLTAGE. Select the mode you want and press the fire button again.

The display will indicate the mode that’s been selected with either “W +” or “V +” displayed underneath the large numerical display.

If you’ve selected “Wattage”, the large numerical display will indicate “Watts” with “W+” underneath and the smaller bottom right value (underneath the coil resistance) will display the voltage that’s being applied to the coil.

If you’ve selected “Voltage”, the large numerical display will indicate “Volts” with “V+” underneath and the smaller bottom right value (underneath the coil resistance) will display the wattage that’s being applied to the coil.

Wattage Mode

If you don’t want to use the Coil+ mode, select “Wattage” from the menu options and this will take you to the standard wattage mode.

Refresh Mode

Coolfire Z60 Refresh Mode Screen Display

Another of Innokin’s advanced technologies, selecting this mode will enable you to automatically or manually select this operation. This mode will in effect apply a lower value pulse, (40%) to what you’ve selected to vape at, to the coil to help refresh the coil by pulling e-liquid through the coil.

Screen Timeout

Coolfire Z60 Screen Timeout Display

When selecting this menu, you can specify the length of time the screen will be displayed after pressing any of the buttons.

The default setting is 10 seconds, but you can select a value from between 5 seconds – 180 seconds.

This value will determine how long the screen will remain illuminated before it goes blank if no button is pressed.

Cut-Off

Coolfire Z60 Vape Cut-Off Screen Display

The default setting for this is 10 seconds. You can select any value from 3 seconds to 18 seconds.

When you press and hold the fire button to vape, the current that’s applied to the coil will remain for the duration that’s been specified in the CUT-OFF menu or sooner if you stop pressing the fire button.

This is a safety feature to stop accidental prolonged firing of the device. When the time is reached in the CUTOFF menu, the display will indicated “CUTOFF” and will stop firing.

Lock/Unlock

If you wish to lock the + / – buttons so they are ineffective, press the fire button and – button simultaneously and the small icon in the top left hand corner of the display will show the status of the lock/unlock function:

Coolfire Z60 Red Lock Screen Display
Coolfire Z60 Green Unlock Screen Display
  • Green: Highlights the control buttons are unlocked
  • Red: Highlights the control buttons are locked

Note: When the control buttons are locked, the fire button will still operate.

Innokin Zlide Top Tank Performance


Two coils from the Innokin range of Z coils are supplied with the kit (0.3ohm and 0.6ohm) and are both Kanthal A1 Mesh material. The Coolfire Z60 only operates in wattage or voltage mode, there is no Temperature Control (TC) feature option.

Innokin 0.3 Z Coil and 0.6 Z DuoPrime Coil
Innokin 0.3 Z  and 0.6 Z DuoPrime Mesh Coils

The Zlide Top tank comes pre-fitted with the new 0.6 ohm coil which is their new DuoPrime tech Mesh coil that’s been incorporated into the Z series of coils. This is stated to improve e-liquid saturation, flavor production and coil longevity by utilizing an inner and outer layer of mesh surrounding the wicking material.

Z 0.3 Ohm Coil

Innokin 0.3ohm Z Coil

Innokin specify the wattage range is between 30W-40W. Best at 35W. Suitable for DTL.

After priming and slowly bedding in the coil at a low wattage, I found the flavor and vapor started to kick in for me at around 10W. Slowly increasing the wattage in increments up to 18W improved the flavor and vapor produced at each setting.

Innokin 0.3ohm Z Coil View 1

My sweet spot for this coil was around 25W in terms of very good flavor and vapor production. With the airflow fully open I was getting a pretty decent DTL vape although slightly closing off the airflow did give me a really nice RDL vape style.

Taking the wattage on this coil up to 40W did increase the flavor and vapor but i felt if I continued to vape at this wattage it may have struggled. Keeping below 35W or even 30W was ideal for me with this coil.

Longevity of the coil is very good as I’ve been using these coils in my Z80 kit with the Zenith II tank for quite a while now. On average I’m getting around 4-5 weeks usage from each coil at 25W.

Z 0.6 Ohm Coil

Innokin 0.6ohm Z Coil

Innokin specify the wattage range is between 9W-13W. Suitable for MTL.

Once primed and bedded in, the flavor and vapor at the minimum wattage setting of 6W was already pretty good. Increasing the wattage to 8W really started to bring out the flavor of my e-liquid and was producing pretty decent vapor. Tweaking the wattage to 10W started to provide quite dense vapor.

Innokin 0.6ohm Z Coil View 1

Increasing the wattage to 12W seemed to give me the best results for this coil. Flavor was really good, giving a slightly warm vape and a nice tight MTL draw with the airflow set to just off the closed position. Opening the airflow fully I would describe as a RDL draw.

I’ve been vaping this coil for a good week now nonstop and am really enjoying it. There is no sign of flavor drop off at all. My only observation is with the airflow half open the draw intake does produce a bit of noise.

Coil+ Results

Quantifying coil life is not easy when trying to make a direct comparison between the two modes. Coil life is impressive on the 0.3 ohm coil anyway so if Coil+ does improve this even more then that can only be a good thing.

Refresh Results

I used Refresh in manual mode after I had increased the wattage on the 0.3 ohm coil to 45W and found the flavor was becoming muted. Once Refresh was carried out, the flavor from the coil did improve.

It’s quite difficult to gauge over a relatively short time if Refresh improves the coil life as there are so many different factors involved. The principle behind the technology makes sense so I can only assume it will do.

Airflow

The resistance of the top airflow ring felt very positive and had no fear of it moving on its own. Top airflow for me is always a good thing and a real benefit in stopping e-liquid seepage when it’s fitted on the bottom of the tank.

Even though the airflow slot is quite thin, it is wide so does allow a lot of airflow entering the coil. The range of airflow adjustment is impressive although I wouldn’t recommend shutting it off completely.

Coil Performance Summary

Both the 0.6 ohm and 0.3 ohm Z coils are very impressive. Flavor and vapor from both are really good. Considering the min/max wattage levels on the 0.6 ohm coil are low (9W-13W), the results are impressive and make for a perfect lower power MTL draw.

The 0.3 ohm coil is more of a flavor and vapor chaser and it certainly does that!

The wicking ports on both coils kept up with High VG juice and equally well with my 50/50 e-liquid.

Any Leaks?

Throughout my time using both the Zlide Top tanks there was no evidence of any leaks when using either of the supplied coils. Because its a top airflow design, this really does help prevent e-liquid seepage. Obviously as the coils get older leaking can start to occur.

Innokin Coolfire Z60 Battery Performance


The Coolfire Z60 mod is powered by an internal 2500mAh capacity battery which is pretty decent considering the size of the mod.

Battery performance is always subjective and depends on the power you vape at, the type of coil you’re using and your vaping style.

On average I was achieving around 10 hours of normal vaping time while using the 0.6 ohm coil at 9W. This time reduced to around 8 hours when using the 0.3 ohm coil due to vaping that at a higher wattage of 25W.

The Coolfire Z60 indicates the status of the battery on the battery icon in the top right of its display so you can keep an eye on the remaining charge of your battery. The battery icon will change color and reduce in size as the charge diminishes.

  • Green = 100% – 60% of charge
  • Yellow = 60% – 20% of charge
  • Red = 20% – 0% of charge
Coolfire Z60 Numerical Battery Screen

Alternatively you can press the Fire button and + button together which will show the larger central battery icon in the color relating to its charge color with a numerical voltage value below it.

Once the battery is depleted of its charge, the Coolfire Z60 will flash up a “Low Voltage” prompt on the display.

I did observe when the battery indicates red and approached its low battery cut-off, the Z60 throttles back. With the watts set at 35W it was struggling to provide that power to the coil. Once the battery charge increased above 3.5V the power was back and fired the coil as it should.

Strangely enough, when I was using the 0.6 ohm coil around 9W there was no loss of power right up to the point the battery indicated low battery.

How do I Fill the Innokin Zlide Top Tank?


The Zlide Top tank is a top filling slide to open mechanism, it really is very easy to fill.

You don’t remove the top cap, just simply slide the top cap in the direction of the indented arrow symbol that’s on the top cap in-between the two hex screws.

How Do I Fill The Coolfire Zlide Top Tank

Once the top cap slides open, the fill port with its white silicone rubber membrane seal will become visible. Pass the tip of your e-liquid bottle through the opening of the silicone rubber seal and fill the Zlide Top tank with your e-liquid.

Once filled, remove the e-liquid bottle from the filling port and slide the top cap back into position ensuring the white silicone seal is no longer visible.

Depending on which of the supplied drip tips you’re using, large e-liquid bottles may not fit too well with the drip tip attached. Simply remove the drip tip if necessary and replace once you’ve filled the tank.

Quick Tip: If you are filling the tank for the first time, drip a few drops of e liquid onto the wick of the coil first. Push the coil into the base of the tank then fill and leave to stand for approx. 10-15 minutes before you start to vape. This will help saturate the wick fully in e-liquid and help prolong the life of your coil.

How do I Change the Coil in the Innokin Zlide Top Tank?


Unscrew the Zlide Top tank from the Coolfire Z60 mod first. Ensure your tank is empty of e-liquid before you try to disassemble the tank otherwise you will have e-liquid spilling out.

Base Cap removed from Zlide Top tank

Grasp the main body and glass section of the tank and slowly unscrew the bottom section of the tank anti-clockwise until the bottom section of the tank unscrews and comes away from the glass and top section.

The Zlide Top Z coils are a push fit type therefore simply pull the coil away out of the tank and replace with a new one. Removing the coil is easiest by grasping the threaded 510 connector at the bottom of the coil.

Flat Sides of the Innokin Z Coils

When replacing the coil, ensure the two flat indents on the coil line up with the two indents of the tank so it fully locates into the tank opening. Once the coil is located it shouldn’t turn. If it does then it’s not located therefore carry on turning the coil until it latches in the indents.

Re-connect the base section to the main tank body and carefully screw the two sections together. Make sure you don’t over-tighten but making a firm seal.

Do ensure that your new coil is primed and when filled, left to stand for 15 minutes so the e-liquid fully saturates the wick. See our guide on Prolonging the Life of your Coil.

How do I Charge the Innokin Coolfire Z60 Mod?


Because the Coolfire Z60 has an internal battery, charging can only be carried out using the supplied USB to Type-C charging cable. Simply connect the cable into the Type-C port on the front of the Z60 body and the other end into a suitable USB power source. The specified charging circuit of the Coolfire Z60 is 5V/1.7A.

When the Coolfire Z60 is first placed on charge, the main screen will be displayed with the small battery icon cycling in light blue with a charge icon to the right of the scrolling battery bar.

After less than 5 seconds, the main display will switch to a larger central battery screen display which shows a graphical power lead, the USB symbol and the battery icon with a cycling blue scale.

This larger battery icon screen will only remain visible for the time that’s set in the Screen Timeout (5 seconds – 180 seconds). After the screen timeout period, the display will go blank at which point there is no visible indication that the Coolfire Z60 is being charged.

Pressing the fire button while it’s on charge will bring up the main screen showing the cycling battery icon and then switch to the larger battery icon but again will go blank after the screen timeout period.

Interestingly, both the smaller icon on the main screen and the larger central battery icon only cycle light blue in color irrespective of the level of battery charge.

Remaining Battery Charge  Screen on Coolfire Z60

Pressing the fire button and + button simultaneously will bring up the other menu showing the battery status, coil resistance and puff counter. In this screen, the battery icon will display the corresponding color (red / yellow / green) and the numerical value of the battery voltage.

I know this charging status is governed by the 4th gen software as we found the same condition of the Coolfire Z80, but I do feel it would be beneficial to show the battery icon cycling until the charge cycle is complete. Having to press a button to refresh the screen to check if the battery is still charging is not ideal.

A Pass-Through function is included which allows you to vape while the battery is being charged.

Charging time from full discharge to fully charged will take approximately 2 hours when using a 5V/1.7A or greater source. This is a little subjective as after approximately 1.75 hours the scrolling battery icon turns static green but the numerical voltage only reads 4.15V. The Z60 body was now cold so I could only assume it had stopped charging.

I left the Z60 on charge for another 3 hours but it never reached the expected 4.2V reading.

One point worth mentioning, when the Coolfire Z60 is being charged, the bottom and casing of the mod does get pretty warm to the touch. Also there are no visible battery venting holes/slots in the Coolfire Z60 body. I strongly recommend to ONLY charge the mod on a non-flammable surface.

As with any vape device, NEVER leave your mod unattended whilst charging.

Innokin Coolfire Z60 Zlide Top Kit Summary


Purple Innokin Coolfire Z60 Zlide Top Kit

The Innokin Coolfire Z60 is a really good quality minimalist mod. Coil+ and Refresh functions has been added to the software to help with coil longevity and performance while together with the DuoPrime mesh technology now added to the Z range of coils make this a very good vaping experience.

Delivering a maximum power of 60W is plenty enough for the range of Z coils available and the 2500mAh internal battery capacity is very good in providing a day’s worth of vaping between charges. The menu structure is easy to follow and the display is bright and clear showing everything you need to know.

The Innokin Zlide Top tank really is a very good MTL/RDL tank and has taken the original Zlide tank to another level. Performance from both the supplied coils that come in the kit are really good in terms of flavor and longevity.

Combining the Coolfire Z60 mod with the Zlide Top tank is a really good match and definitely complements one another. Available in the 7 different colors, there’s plenty of choice to cater for everyone.

For me, all of the Coolfire range (maybe not the Coolfire 3) are very good in terms of build quality, styling, performance and robustness and the Coolfire Z60 Zlide Top is no exception. Innokin’s track record and customer service really are insurance that you’re buying a quality product.
