About the Innokin CoolFire Z50

The next generation of the Innokin CoolFire range; this is the Z50. The Innokin CoolFire Z50 combines utility, power and style into one handheld device.

The CoolFire Z50 adopts a 'mini-mod' aesthetic; it's larger than a vape pen but is still compact enough to keep in your pocket comfortably. This premium device is built around a powerful 2100mAh battery, which is easily capable of lasting all day, even with persistent use. Naturally, the CoolFire Z50 is manufactured to an exemplary standard - as with all Innokin hardware!

Customisation is the name of the game with the Innokin CoolFire Z50. Both wattage and voltage are customisable using the intuitive adjustment buttons, and airflow can be fine-tuned using the simple adjustment ring on the base of the Zlide tank. Capable of outputs up to 50W, the Z50 harnesses serious power. To further refine the way you vape, experiment with the various Zenith coils available; a 0.48ohm coil is great for high-VG e-liquids and will produce larger clouds, while the 1.6ohm coils offer a tighter mouth-to-lung draw for high-nic e-liquids.

Ideal for beginners or those who want to upgrade from their current pen or pod vape, the Innokin CoolFire Z50 is a capable and stylish mod that gives you complete freedom over the way you vape.

What is Electric Tobacconist Returns Policy?

The Electric Tobacconist Ltd abides by the Distance Selling Act (2000). If, once you have purchased items from us, you decide you no longer want them, then you have 28 calendar days in which to return them and we will refund them in full within 28 days of the cancellation date (including any postage and packing paid) as long as the packaging remains unopened. This excludes e-liquids, clearomizers and disposables.


What's the difference between a vape kit, a vape pen, an all-in-one and a pod mod?

Names are often manufacturer-led, but in general, there's not really any difference between a vape pen and a vape kit, except a vape pen tends to look more like a pen! 

A pod mod tends to be the more modern version of the above, whereas vape kits and vape pens have clearomizer tanks that need refilling, pod mods have pods (capsules) that are pre-filled (either by the user, or as they come) and are taken off and replaced as and when needed.

All-In-One (AIO) kits are similar to vape pens but rather than using removable tanks, the battery and tank is one combined unit.

Do I need to buy anything else to get me going?

Check if a battery is included (in the "What's Included" tab), and if it is then the answer is no - you're set to go. The kit contains everything you need to start vaping right away (including a USB charger). You may want to add a UK mains plug though.

Don't forget to add your free e-liquid (on kits that do not come with e-liquid included in the box, a pop-up window will invite you to add a free e-liquid after adding this product to basket).

Does this kit come with e-liquid?

Yes, but we leave it to you to choose your free e-liquid bottle. Upon adding this product to your basket you will be presented with a button asking you to select your e-liquid. From here, you can choose to add as many as you want, but only the first one is free. (note: if you choose liquids from other tabs these will not necessarily be part of the free liquid offer).

How do I fill a 'top fill' clearomizer?

To fill a 'top fill' clearomizer with e-liquid, simply unscrew the mouthpiece at the top, now tilt the unit to a 45% angle and pour the e-liquid into the barrel against the inside wall of the clearomizer. The aim is the coat the inside wall with e-liquid. Avoid getting it down the central metal barrel (aka the breathing or central pipe) as this may cause it to leak.  Do NOT over fill your clearomizer.


What is Sub Ohm vaping?

Sub-ohm simply means the resistance of the atomiser coil is below 1.0 ohm. Sub-ohm coils are generally larger and therefore can utilise more power and cover a greater area of wick - a combination which results in massive vapour production. A high-powered device paired with a sub-ohm tank is required for sub ohm vaping.

"Direct-to-lung" is the suggested vaping style for most sub-ohm devices (as opposed to "mouth-to-lung" -  i.e. how a traditional cigarette would be smoked).

High-VG (over 60% VG), low nicotine (6mg or lower) e-liquid is recommended when using sub-ohm devices.


What is the warranty on this product?

This product comes with a 90 day warranty from the date of order. However, this does not cover misuse, damage or standard wear and tear.

Another great little kit. Zlide tank is superb. Coils are great too. Slightly on the heavy side, but overall great value for money.

My husband loves it ideal for work he in a trade so the protective casing around the tank is perfect.Fits nicely in his pocket.Easy fill.Easy set up.Great little item.

Bought to replace my Innokin Zenith which has started to be intermittent. It's much lighter and very easy to use. Also better having the lock for the liquid, which means I no longer forget to close it!

9th December 2020 - Trish Pollok

Love the Coolfire Z50, gives nice smooth flavour with my 50/50 liquids using the 0.8 coil and looks stylish.

3rd December 2020 - Jill Davis

Very well made; easiest tank to fill I've ever had; excellent battery; very compact and pocket friendly. Silver finish looks the mutts nuts.
A step up in every way from the EZ Watt, which itself is very good (rubberised paint flaking off though!)

Great vape with a quality feel, long lasting battery and easy tank to use.
Nice and light for pockets and good size to hold. Love it for a stealthy vape at work!!

Really like this from Innokin. It is small & neat but does the job. Love the Zlide feature as well I don’t think I would use anything else it is so easy. Also with changing coils just pop it in. Great product.

22nd October 2020 - Joy Warricker

Really like it, it is small which is what I like about it. I have been use to using the Kroma-R Zlide which is great but a bit heavy. I really like the Zlide versions and I think this Coolfire one is better than the Kroma but it is an individual taste so yes, 5 stars for the coolfire.

16th September 2020 - Joy Warricker

Had some bad experience previously with my vapes. But this one ticks all the boxes. Perfect for mouth to lung vaping. Not harsh, very smooth.
