  6. Will the Zenith coils be compatible with the Zenith D22?

  7. I’m looking for a MVP4 mod and can not find one on your website. Can you direct me to a website where i can purchase one ? I found a couple but dont know if they are authentic.
    Thanks !!!

  8. What are the dimensions of the Zenith D22 2/3ml? is it taller than the original Zenith? thanks

  9. Can we use this device (CoolFire Mini Innokin Zenith D22) while it’s charging? What I mean is can we vape while charging?


  10. I have purchased the innokin mini and even though it’s fully charged when I take it off charge the red indicator light remains on. When I turn it off the red indicator light still remains on. Is this something I can fix or is it faulty and should take it back for a replacement?

    • Hi Craig,

      Try power cycling the device. Press the fire button 3 times to turn it off, wait a minute, then repeat the process to turn it back on. If that doesn’t help, contact your vendor for a warranty replacement. Apologies for the inconvenience.

  11. Hi there,

    Can you use MTL vape juice with this device?

  12. i have just purchased one,
    i have put the vape liquid in and waited 5 mins before vaping and it tastes very burnt and not very nice,
    will the taste go the more i use it?

  13. Hi guys, do you know at what temperature celcius does it burns the e-liquids ?

    • Hi Valerio,

      It depends a lot on the coil structure, but it typically requires at least 100C of heat for eliquid to vaporize, and the typical heat range of vaping is between 100-300C. Thanks!

  14. Hi there,

    I use a 3MG e-liquid (70/30) in a sub ohm device. I want to switch to a MTL device, and I am interested in CoolFire MIni. Would using a 3MG e-liquid in this device give me the nicotine satisfaction I am use to, or would I need to use a higher MG e-liquid?

    I ask because I’ve been told that MTL devices deliver less vapour on the inhale and exhale compared to sub ohm devices, which means that a 3MG e-liquid in a MTL device would deliver less nicotine when vaped.

    • Hey there Julian,

      You would likely need a slightly higher nicotine concentration to get the same satisfaction. Probably around the 6mg or 9mg range depending on your taste. Their is a more dense, concentrated feeling of vapor from MTL tanks as the airflow is smaller, but the total amount of vapor is still much lower than a sub-ohm hit. So you’ll need to up your nicotine concentration accordingly. Hope this helps!

  15. Hi
    How often should you need to replace coils..I’m getting a week out of one. Does that seem right???

    • Hey Dianne,

      A week with typical use seems about right. Then can last up to two weeks if you are a lighter use. Very heavy use can sometimes require a replacement every few days. Thanks for contacting us and hope this helped!

  16. Hi, I have purchased a d22 tank having previously used the original zenith which unfortunately broke. I have noticed that the coil does not sit firmly in the slot as it did with the original and slides in and out far too easily.

    Looking in the spare o ring pack, there is a black o ring included. Does this go into the coil slot and if so could a defective original o ring be causing the coil to feel loose?

    • Hi Sam,

      The Zenith D22 is a smaller tank in diameter compared to the regular Zenith. Coils should be press fit and slide snugly into the slot. If they are loose for any reason, it sounds like a tolerance issue with either the coils or the coil slot opening.

      Replacing the o-rings could potentially alleviate the issue. Try swapping in some fresh o-rings to see if your problem is solved.

      You can also purchase spare parts and o-ring kits from Hope this helps!

  17. Hi there,

    My Zenith D22 is gurgling and creating spitback. I’m using the 0.5ohm coil with a 70/30 e-liquid at between 15 – 18 watts. What would be causing this and how can I stop this from happening?

  18. Hello I recently purchased this vape and love it, I am very new to this and when I brought it the shop told me not to charge it with more than a 1 amp charger but I can’t find any wall charger so low, what power output are these best charged with?? Thanks heaps

    • Hey Julian,

      It sounds like your coil is flooded. I’d recommend replacing the coil, and being careful not to over-prime your new coil. One drop per cotton juice port is enough.

  20. Can the Zenith Tank be used on a T22 battery? I have an extra tank it would like to use it, but wasn’t sure. Thank you.

    • Hey Katie,

      The Zenith can be used on a T22 battery only using the 1.6ohm Zenith coil, as the T22 is designed for 14W to a 1.8ohm coil. The vape may be slightly underpowered, but should still be pleasant. Thanks!

  21. salve. ho uno zenith d22 (kit mini cool fire + zenit d22. le coil sono tutte uguali per gli zenith? grazie

  22. Hi.
    I wonder how I can see the difference between the 2ml and 3ml tank.

  23. Salve, con la coolfire mini si può utilizzare l’atomizzatore ares mta?

    • Ehilà,

      Puoi certamente usare Ares RTA con un CoolFire mini, a patto che tu costruisca una bobina che funzioni all’interno delle specifiche del CF mini. Costruisci una bobina per lo svapo MTL che vapori bene tra 10-25 watt.

  24. Where would I purchase coils for replacement for this vape?

  25. Hello,
    can I have some information regarding the battery life? For example how many puffs at 4,5 volt ? Do you have any table with the informations regarding the discharge or any other info?
    Thank you!

    • Hi Lollo,

      A table as you describe would be hard to create as wattage settings and puff length greatly change the battery life. Ultimately, it’s extremely varied depending on vaping style.

  26. Why won’t my innokin cool fire mini not turn on now ?

    • Hi Graeme,

      Make sure the mod is fully charged. Try a different charging cable to see if the issue is within the charging cable or adapter. If a new cable doesn’t help, try a different adapter. If it still won’t charge, the mod may be damaged and need replacement. We offer a 90 day limited warranty policy that covers defects like these. If you’ve purchased it within 90 days, please contact our support email as soon as you can with attached proof of purchase and a brief description of the issue. Sorry for the inconvenience and hope you can get the issue resolved quickly.

  27. Other then using a mains charger adapter. Is there any way I can charge the unit on the move. Like issuing a usb power pack or in car charger?

    • Hi Dave,

      You can use a power pack as long as it’s 1A charge rate or less. Do NOT use a car charger to charge any Innokin product, as you run a very real risk of damaging the battery and voiding your warranty. Hope this helps.

  28. I’m in the USA. Last week I bought a Coolfire Zenith Kit and I liked it so I figured I’d buy a second D22 Zenith tank to use with the Coolfire Mini kit battery as a second tank. Well I got the second tank today a D22 and it is 1/4″ taller than the tank that came with in the Coolfire Mini kit. So this new D22 tank is a 1/4″ taller on the Coolfire Mini battery which looks a bit odd and doesnt fit in pocket as well. I dont see a listing for the shorter Zenith tank thats comes with the Coolfire mini kit. Is the shorter tank available or is the only way to get the shorter Zenith tank with the Coolfire Mini kit?

    • Hi Jim,

      It sounds like what you purchased was a standard Zenith tank. The standalone Zenith is a bit taller than the D22 that is bundled with the Coolfire mini. Check with the vendor you purchased it from that your order was not wrongly fulfilled.

  29. Hi.

    Please inform the dimension of the Innokin Coolfire mini c/w the Zenith tank.
