  • Description

    The SERIES-C Mini V4 vape tank is designed to offer vapers who prefer the smaller form factor of our V3i batteries the opportunity to use a tank with their kit.

    These reusable vape tanks allow you to simply swap out the coil when it needs replaced. The pack contains 1 full tank, pre-fitted with a coil, plus 2x replacement coils.

    These discrete, transparent tanks measure just 35mm, equalling the length of our standard cartomizers, and are perfect for use with any of our V3i batteries.

    • Length - 35mm
    • Capacity - 0.7ml
    • Resistance - 2.0-2.2Ohm


    The use of bottom-fitting coils lessens the risk of dry-burning the wick, though tanks should still be left for around 20 mins after filling to allow proper saturation (longer if using a VG e-liquid).

    As the tank measures just 35mm in length, it is possible to store them in your V1P PCC while attached to a 55mm or 65mm V3i battery.

Customer Reviews for the SERIES-C Mini V4 Vape Tanks

  • HIgh hopes, but just not working. - by cholly, 11 August 2020
    So I ordered two packs of these as the old type were out of stock. So far I've got through the first pack in about two weeks - the first tank, the tube snapped off as I was fitting the wick - probably klutzty me.

    All the other wick units have started spitting liquid within a day of use so you end up with hot liquid spitting into your mouth as you're drawing on it - not nice. They look good and practical but don't work for me, but I've ordered a pack of the old style now and I'll be returning to them for now. .....................JAC: Sorry you are having issues. Please contact customer service and they will help, as there is a slight adjustment needed if you are not used to using tanks.
  • overall, pretty good - by Richard, 24 July 2020
    Far more consistent than the normal carts and seem to last a bit longer. Can be a bit messy getting the coil out to refill though, and I'm getting through a lot more liquid.

    Also frustrating that I can't order coils without getting a new tank as well
  • The manual batteries were greta and then they stopped selling them! - by Richard, 13 July 2020
    Great product but hopeless now they have stopped selling the manual batteries. The manual batteries were £1.99 each, the auto batteries £9.00 each. The only difference is the button and they don't last that long. I would have been happy paying more the for the manual batteries, but no, Jac Vapour has stopped selling them completely. Bonkers and they have lost me a as a customer. Really annoying...........JAC Vapour: Unfortunately the manual batteries do not sell well at all, that is why we were selling them under the cost of production, to clear the stock. Also I think we were the only company to still do such a product. Nearly every user of the smaller batteries uses the auto ones. If it is the manual battery you like then the only real option is to move to a larger device, something like the VIM and is still very compact, or the S17. As a bit of insight, To keep production lines open and manufacturing a product we need to order large qtys, the manual batteries only sold 80 units in the whole of last month. The auto batteries sold 5000. I am sorry the decision to stop stocking them has affected you and it will be be a shame to lose you as a customer, but I hope the extra information helps explains the logic.
  • These are very good - by Richard, 29 November 2019
    I've been vaping for over ten years and been through three or four different brands as the companies concentrated on the bigger tanks etc and dropped the cigarette sized tansk from their range and the price went up and up. These are really good after you have the knack of using them. When filling they are upside down so the wet bit (battery & coil) look as if it can drip. Surprisingly it doesn't and I just stick in between the cushions of the sofa to keep it upside down. Don't fill past the bottom of the tube! They don't hold that much liquid but it's not a problem for me. I was using a much larger unit previously and guzzled far too much liquid and clouds of vapour annoyed people. This is small enough to use in the pub and it doesn’t annoy anybody. It's good that some of my old batteries KR808 batteries fit too. Only four stars as I was promised the rubber/plastic mouthpiece to go with it that wasn't in the package when it was delivered. Bearing in mind, I specifically asked for one when I spoke to one of the sales staff before ordering. I think there is a glitch in the ordering system on the website. The only option for the mouthpiece is no thanks!.........................JAC: Thanks for the review and the tips. I apologise for the mouth tip cover not being in, it is set to no thanks, as we can't fins another manufacturer of them at present, so we have no stock, but we are looking for a new manufacturer, If we find one we will put them back up and options will show.
  • Very good, but... - by Dominik, 28 May 2019
    After using cartomizers, while serviceable, the biggest gripe I had with them is that I couldn't see how much liquid I had left in them until it started tasting horrible. After finally getting these tanks however I was floored by how well they worked compared to the carts, both in taste and vape production, the tank is nice and clear so I can never worry about going out and wondering how much liquid I have left. However the build quality is something less to be desired. While the tanks themselves are sturdy and well made, the coils are hit and miss. When I got my pack the first coil that was already attached to the tank didn't work whatsoever. Support told me to carefully lift up the center post on the battery as some coils don't get contact but even with that done, the coil didn't work. They also said that the average lifespan of the coils is 5-7 days, which is absolutely absurd and short (personally my first coil died after 2 weeks and even then I was shocked it was dead that fast). Now one would think, with this low price it's not a big deal but if you're not living in the UK, buying a pack of coils can set you back with shipping alone. Topping off the liquid in the tanks is also a bit finicky and messy, so be prepared to blow out excess liquids from your mouthpiece as well as the occasional drop going to your tongue, but from what I heard, this is a common problem with almost all sorts of e cig tanks. Regardless I would strongly recommend these tanks versus the cartomizers, just be aware of the dubious quality coils...........JAC: Thanks for the feedback, and it does sound like you had a faulty coil, but it shouldn't be common. Any faulty ones you do get we can replace, if outside the UK, then we can pop in replacements when you next order, I would also advise priming the coil, which means dripping a few drops of eliquid onto each wick prior to fitting, it gets things going faster. The advice of 5-7 days is based on variation in eliquid, Some liquids can kill coils in a few days, for instance overly sweet stuff, and also high VG will reduce lifespan, but most will get a good bit longer, if you avoid allowing the wick to run dry. Once you fill a quick flick of the ecig (hold at bottom and flick like a fishing rod) will avoid any excess that may have flowed into the airflow, and prevent the liquid in the mouth that you mentioned. I hope this helps.
  • Used to be good but...... - by Robin, 5 March 2019
    I've been a JAC customer for several years and been absolutely delighted with the products and service. However, and it truly pains me to say this, these tanks and coils have become a complete mess. I've been using them for a few years but over the last 18 months or so the quality has massively deteriorated. Every time I open a new pack I wonder how many, if any, will work perfectly. I've just started a new pack tonight. The first coil delivered yet another horrid burnt taste, so I'm on my second coil within 12 hours and it's the same story. Is this yet another dud pack and a waste of money? Sure, JAC have been wonderfully helpful, sending me replacement coils etc. but it's come to a point where I'm really reluctant to order these products again. The quality of these products was once great but is now atrocious. I really don't know what to do. It's so disappointing......................JAC Vapour: Thanks for the feedback and sorry you are experiencing issues. Can I ask if your entire setup is the same, so eliquid hasn't changed, i.e. from a PG base to a VG base, also can I also ask you to try priming if you are not, to make sure that's not the issue. To prime the coil put 3 drops on each wick hole, so the wick can pre-saturate, do this prior to fitting in the tank. I will also test mylsef, as I have currently not heard of other similar issues.
  • Bigger holes make a better vape. - by Colin, 19 January 2019
    I purchase one of these mini tanks because i like the small form factor and that it also is much more like a normal cigarette. The first one i had seemed to work ok but i had to keep taking it off the battery and priming it. My initial thought was maybe i had a bit of a dude one so because i actually really liked the small form factor i purchased several more. I tried the new ones i purchased with the Jack Vapour battery and a 50/50 eliquid. I had a couple of DOAs and the others i have used constantly were giving dry hits and the only way to overcome this was to keep removing from battery and priming them. I have now come up with a solution. I have now realised that the small holes on the atomizers are just that too small and are not letting the liquid through to soak on the wick. I grabbed a hammer and a hole punch and with a light tap i have made the holes slightly bigger so the liquid has plenty of room to soak through to the wick and now they work really well with no dry hits. If the atomizer was redesigned with a larger holes this would be an amazing little device.
  • Hit and Miss - by izabella, 5 July 2018
    I have been buying these since they came on the market, Great little tanks, except for duds. So far I have bought quite a few and had quite a few duds. Customer services have always been brilliant and sent out replacements for them but it is still happening, as another reviewer said they had a pack that went straight in the bin. the last pack I bought was one dud after the other, all three went in the bin. when I last got a reply for the team at Jac they mentioned it might be something to do with the liquid or my device? but I am pretty sure it was they were duds.

    The feel I got from the email which offered to send out replacements was that they were probably not going to do so again? I have not contacted them re the last pack of duds as it was intimated that they were not going to continue to honour sending me out replacements.

    I have just ordered another pack, hopefully they will not go in the bin...……………...JAC Vapour Ltd: Thank you for the feedback. Since you started using these has anything changed in your setup, for instance are you using the same eliquid, these tanks will cope with 50/50 juice fine, but not anything like above a 50% VG liquid, so the premium VG options would be too thick, but the standard range and PG originals or the premium PG will be fine, also if you get duds maybe we could look at some of them, as when I test here they appear to be fine, but I don't use these a lot, so it's no comparison to a user that uses consistently.
  • A great buy - by Vapourteach, 1 June 2018
    These are much better than the cartomisers and the coils actually last longer than stated in the description.
  • Superb Tanks - Quality Control Issues Recently? - by SK, 13 March 2018
    Superb tank/coil. Flavour and vap production on par with much bigger devices.

    Used since launch with no problems whatsoever, no leaks. Can last weeks of daily use.

    Now available as coils only packs ending my growing collection of unused tank tubes!

    HOWEVER: Last pack has serious Quality Control issues. 2 coils burnt within the first hour, and the third had some kind of contact problem where it would not fire consistently, then at all. All 3 went straight in the bin :( Never seen problems like this before.

    JAC please keep an eye on QC, these tanks are the BEST!.....................jAC Vapour Ltd: It sounds like you have had a bad pack, I've checked with CS and they say no other issues have been reported, but if you contact them, then they'll get them all replaced for you. Thanks for the review.
