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. Some kits may not include charging cables; please check the "what's included" section prior to purchase.

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).

Can I replace the coils on this clearomizer?

Yes, this product has a replaceable coil, so once the coil needs replacing, you do not need to buy a whole new clearomizer. Click here to see our replacement coil pack department.

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.

Innokin CoolFire Z50 Reviews

Great device, very good quality and well built, best thing about it is I've had it a few weeks now and still no sign of leaking

2nd June 2022 - Craig Tickle

Leaks like a baby. Battery life poor. Stopped working altogether after a few weeks.

24th May 2022 - Anonymous

I like it and works brilliant just not happy you can't change battery, and to be honest I would of chosen different ecig if I had read about it properly, let me just see how long battery lasts

1st May 2022 - Yvonne Oldroyd

Excellent vape. The way you fill the tank using the slide opening is a massive improvement. No more unscrewing tanks and spillages, so simple yet so effective. Build quality as ever is very good. Feels solid in your hands and comfortable. It's a well designed and engineered vape. With all that, for the price, it's an excellent buy and value for money. Previous to this I had the EZ.WATT and this is so much better. Better tank, better filling method and better battery. Been vaping for many years and I Highly recommend this.

29th April 2022 - Phillip Kimpton

Excellent vape for the price small and Discreet also … 2nd one I’ve bought

1st March 2022 - Catherina Marcroft

Seems well made time will tell

17th February 2022 - Kevin Wall

Yes it’s good but you didn’t send silver you sent me a black one.

17th February 2022 - Pauline Moore

Brilliant kit so easy to use. I didn't think the coolfire could get any better and it has

31st December 2021 - SHEILA GLEN

Great product , very good value for money. I have purchased the innokin coolfire before and won’t hesitate to buy again. Easy ordering and quick delivery

4th December 2021 - Dawn Roddis

Love this vape, had many different vapes and this is by far the best one ever, no leaks, no burning taste when the coil needs changing, just a constant nice taste and a good vapour. So good I bought two more as spares for my other handbags

25th November 2021 - Jayne Pimblett

I actually have the black one not the silver, very impressed made the step up from a Vuse ePod, find it a nice transition, settings aren’t to confusing and the product is a nice size, not overly bulky like a lot of box mods, the two coils sent with the product were totally different though and the one that came pre-installed burnt out very very quickly, so might be worth buying an additional spare

22nd November 2021 - Dominic Barker

very good value works a treat

17th November 2021 - Anthony Sharpes

My first mod some years ago was the Innokin CoolFire Mini - and I still use it regularly. I wanted a new one because I preferred the taste but they are no longer made the same so I bought this model, the CoolFire Z50 in the Blue colour. I have to say I am very impressed. The finish is a deep blue with a shiny gold band around it, matt finish, slightly larger than the Mini version and with the updated top but, thankfully, still the same coil. There is a larger chamber to hold more e-liquid which is very helpful. The battery is also larger and better quality - it took just over 2 hours to reach full charge using a desktop pc, and I only have to charge it every 2 days instead of daily. My other mods are now not being used, this CoolFire Z50 covers everything I need and I can highly recommend it.

I have used a previous model for a number of years before finding this one and so delighted with it. So easy to set up and use. Especially the the filling system. It also feels good in the hand.

5th October 2021 - Ray Evans

very good thank you very much

28th September 2021 - Lou Spinelli

Very happy so far. Easy to use and good features

Best ecig I have had no leaks. Quick delivery definitely recommend

14th July 2021 - Paula Priestman

It’s a very good vape , however when I received this vape , the coil had already burnt or had just broken upon arrival. Luckily it came with a spare coil but I didn’t enjoy the burnt taste.

I replaced my EZ Watt with the Coolfire and I am glad I did. It is comfortable to hold and fits nicely in your pocket. Settings for wattage etc are easy to adjust, as is the airflow, allowing you to get your perfect vape. The sliding top for filling is a big bonus rather than fiddling around trying to unscrew the top off the tank. I have been using the Coolfire for just over a week with no leaks or gurgling at all. For me the battery lasts a couple of days. I am very happy with the Coolfire and honestly can not think of one con to mention.

29th April 2021 - Andy Connion

Trying to come off cigeretres and liked the look of this one and reviews seemed really positive. Ordered on the Friday and arrived by the Monday. Very easy to set up, and was ready to use straight out the box. I'm not very tech savvy with vapes, but managed to work out how to change the voltage and watt to suit my preferences and it was very straight forward to fill and change coils. Had an issue with "check automizer" but just changed the coil it came in, and put the new one in and seems to work perfect after that. Got it in the Pink colour and looks very pretty. Had a previous Innokin that leaked a lot, but this one is a lot more secure and sturdy, so hoping I can keep at it and say goodbye to cigarettes for good!!

19th April 2021 - Hannah Johnston

Fantastic choice, for the vapour not wanting to disappear in a cloud of vape!
Small enough for a pocket, clean fill and easily charge battery, great product.

19th April 2021 - Paula Cooper

Amazing - couldn’t recommend enough as someone who’s not familiar with vaping this has changed my life. Fits perfectly in your hand and pocket, but it’s powerful and I’ve been loving it! (Actually got the pink one cos it’s hella cute too)
