Innokin Coolfire Z50 Zlide Review

With all the vape pods and pod mods coming out virtually every day, it’s hard to find a classic mouth-to-lung setup anymore. Luckily, though, we still have die-hard MTL fans looking for an authentic mouth-to-lung vaping experience, and companies willing to cater to them. The Innokin Coolfire Z50 Zlide is one of these rare mod-and-tank MTL kits that cater to old-school vapers, and it’s actually designed in collaboration with two of the most popular old-school vape reviewers on YouTube – Phil P. Busardo and VapinGreek. Let’s check it out:

Innokin Coolfire Z50 Zlide Packaging

The Coolfire Z50 Zlide kit comes in a fancy cardboard box with a side-sliding wrapper featuring a picture of the device inside on the front, a list of contents, the usual warnings and manufacturer contact information on the back, as well the signatures of P Busardo and VapinGreek on the sides, which I though was a nice touch.

Inside the box, we have the compact Z50 vape mod, the popular Innokin Zlide tank, a spare glass tube for the tank, spare coil-head (another comes pre-installed), spare drip tip, micro-SUB charging cable, user manual and a safety manual, which you don’t see very often.

Innokin Coolfire Z50 Mod

The Coolfire Z50 is made primarily of zinc alloy, measures 69mm x 34mm x 26mm, and comes in five different colors (black, gunmetal, stainless steel, blue and pink). The blue version, which I received for this review, has a very nice sandblasted finish, which not only looks and feels very good, but also eliminates fingerprint marks and smudges.

As you can tell by the above listed dimensions, the Z50 is a very compact vape mod, so you can easily carry it around either in your hand or in a small pocket. The ergonomic design makes it very comfortable to use and hold in the hand, so I have nothing to complain in this department.

Starting at the top, we have a classic 510 connection with a protective stainless steel plate, and a gold-plates, spring-loaded pin. The mod accommodates atomizers up to 24mm in diameters, but you can get away with 25mm as well for just the slightest bit of overhang.

Apart from the button and display panel, the sides of the mod are very clean, with a thin gold trim, some discrete branding and the mini-USB charging pot being the only noteworthy details. The button panel is pretty clean as well, with a round fire button with elegant gold trim near the top, a decently-sized rectangular OLED display and two opposite facing arrow-shaped power adjustment buttons.

I particularly like how the black cover of the display matches with the gold trim, it’s actually one of my favorite color combinations, although that’s definitely a subjective pro.

Finally, on the bottom of the mod we have the capacity of the build-in battery (2100mAh/7.7Wh) and a little on/off switch. You don’t usually see something like this on vape mods, as most have that ‘5 clicks on, 5 clicks off’ command, but Innokin decided to implement an extra layer of security.

When carrying a mod in a tight pocket or purse it’s possible (albeit unlikely) that the fire button get pressed five times in rapid succession, which would turn on the device. With this safety switch on the bottom, you don’t have to worry about something like that occurring.

That’s about all there is to the mod, and as a whole I really like it. The build quality is solid, as is the paint finish, and although I’m not a fan of gold in general, I think it goes very well with the dark blue and black of the display cover. For a compact, integrated battery vape mod, the Coolfire Z50 is very nice!

Innokin Zlide Tank

The tank has been around for a while now, and although this was my first time using it, I had already heard great things about it.

The Zlide is a top-fill 24mm diameter tank, with bottom airflow control designed specifically for mouth-to-lung vaping. It holds up to 4ml of e-liquid and comes in the same colors as the Z50 mod, only the finish may vary. For example, the blue one I got for this review has the same sandblasted finish as the mod, while the one that comes in the black kit is glossy.

The blue 510 drip tip that comes pre-installed on the tank is made of a resin-like plastic and looks decent, but I really like the gold one included as a spare. It matches the gold trim on the mod and on the fire button beautifully and is metallic, which I prefer on MTL tanks.

One functional difference between the two drip tips is the tiny knob at the bottom of the plastic one, which is missing on the gold one. This knob acts as a safety stopper for the sliding top cap, preventing it from accidentally sliding open when you’re transporting it. When you want to slide open the top cap all you have to do is pull on the drip tip a little to get the knob out of the chimney leading down into the tank.

The Zlide tank features a metallic frame that wraps around the glass tube, thus offering better protection. Unless you’re unlucky enough to drop the exposed glass on a pointy surface, the metal casing should protect it against most impacts.

The airflow system at the bottom of the Innokin Zlide tank consists of four tiny air slots on just one side of the tank, which is unusual. But then again, you don’t see many MTL tanks these days… Anyway, even with the four slots exposed you only get enough airflow for an airy mouth-to-lung vape, so don’t expect a loose draw, because you’re not going to get that with this tank.

To change or inspect the coil, all you have to do is unscrew the base of the Zlide tank, and pull out the coil. It’s best to do this after emptying the tank of juice, otherwise it will spill through the thin chimney. When inserting a new coil-head, make sure you insert it all they way in, by lining it up correctly with the edges of the tank port.

All in all, the Zlide is a simple-to use, and solid-feeling MTL tank, the kind you don’t see very often these days.

Innokin Coolfire Z50 Menu and Features

The Coolfire Z50 isn’t the most advanced vape mod in the world. It doesn’t comes with built-in bells-and-whistles or advanced vape modes like custom power curves. You only get wattage mode and voltage mode, but they’re more than enough for the average vaper, especially since this is a device designed primarily for MTL vaping.

Before you can fiddle with the Z50’s menu and features, you first have to turn it on. Out of the box, that switch on the bottom of the mod is turned off, so make sure you flip it on. Then, you still have to press the fire button three times rapidly to unlock the device. Now you’re ready to go through all the features.

The Z50 turn on in wattage mode, but you can always switch into voltage mode simply by keeping the fire button and the ‘down’ button pressed simultaneously for a couple of seconds. To switch back into wattage mode, do the same operation, only with the ‘up’ arrow.

To adjust the wattage/voltage, all you vae to do is hold down either the ‘up’ or ‘down’ buttons until the screen starts flashing, and then you can use the same to keys to adjust the power output in 0.5 increments. The mod has a wattage range of 6W – 50W and a voltage range of 3V – 7.5V.

By holding the ‘up’ and ‘down’ buttons pressed, you can change the orientation of the screen, a feature I personally haven’t seen on mods in a while.

Innokin Coolfire Z50 Battery Life

The Z50 has a battery capacity of 2,100mAh, which doesn’t sound very impressive. We’ve seen pod mods with 1,800mAh batteries, but those weren’t designed exclusively for MTL, like this mod. As the ”50″ in its name suggests, the Coolfire Z50 has a max power output of just 50W, which, again, isn’t that impressive, but if you’re going to use with the Zlide coil-heads, it’s more power than you’ll ever need.

The 1.2Ω coil-head has a recommended wattage range of 10W – 14W, and the spare 0.8Ω coil-head works best between 15W – 18W. Those are really low power outputs, so that 2,100 mAh  battery will mostly likely last you for a whole day, depending on how much you vape. So don’t let the relatively low mAh rating fool you, the Z50 has plenty of battery life if used as intended.

The one gripe I have with this mod in terms of battery is the outdated micro-USB charging interface. It’s nothing major, but with most manufacturers already using Type-C USB, it’d be nice to see Innokin get with the times as well.

Innokin Coolfire Z50 Zlide Performance

Things like build quality, design and battery life are all very nice, but what vape kits ultimately boil down to is performance, and that’s where the Coolfire Z50 Zlide really shines.

In recent years, with so many pod systems and pod mods to review, I found myself getting back into MTL vaping, and I’ve found that really good mouth-to-lung vaping devices are hard to find. I’m talking about those tight-draw, cigarette-like setups that got me into vaping all those years ago, minus the laughable battery life and rudimentary coil-heads, of course. The Z50 with the Zlide is exactly that kind of device!

Whether you’re using the 1.2Ω coil-head or the 0.8Ω one, you’ll be rewarded with a super-tight draw, clean flavor and just enough vapor to make the vape pleasurable. The higher resistance coil-head will give you a slightly cooler vape, but also a tighter draw, but you can get the same restrictiveness with the 0.8 ohm coil-head by adjusting the airflow on the tank. I’ve been enjoying both coils, but I would give the 0.8Ω a slight edge because of the warmer vape.

I’m really struggling to come up with anything negative to say about this kit, to be honest, because I’m loving it so much. I definitely can’t fault it in terms of performance, and I’ve personally had no spitback or leaking issues with it either. It’s become my daily setup and I see myself using it a long time going forward, especially with so many other Z coil-heads left to try.

Conclusion

If you’re into MTL vaping and don’t care too much about the plethora of pod systems and pod mods available on the market right now, the Innokin Coolfire Z50 is an excellent alternative. It’s a classic mod and tank combination, so you’re not tied to a closed system like you are with the above mentioned devices, plus the performance is really outstanding at this price range. I honestly don’t have anything to complain about with this kit, and I wholeheartedly recommend you try it!

The Innokin Coolfire Z50 Zlide kit was sent to me by Sourcemore for the purpose of this review. They currently have it in stock for only $34.68.
