Customer Reviews for the JAC 510 Twist 650mAh Twin Battery Pack (Free Charger and Case)

  • Absolute quality! - by Lewis, 31 December 2015
    Wow what a piece of kit!
  • Great Product - by Dan, 9 August 2015
    Received this a week ago and immensely impressed with this product… was my partner so have to get another pretty quick! The design is well balanced, found this easy to assemble and re-fill, the battery life is impressive and the e-liquid flavours give a really good vaping experience.
  • very impressed, should have done it a long time ago - by Daniel, 7 August 2015
    I have been thinking about moving to ecigs for a while but kept putting it off as i found it a little confusing with all the different types and lingo. I sat down and found this site and it explained everything so well so i ordered this one. It came extremely quickly in the post along with a few flavours i ordered. Charged them up and began, havent looked back since. Battery life i find to be really quite good i only run it between 3.3v-3.8v and find this is fine for me. Ive since ordered more wicks and coils and another flavour. Great product, great price and excellent customer services from the team .
    Cannot recommend it enough.
  • Worth every penny - by Drew, 3 February 2015
    Recommend this kit to anyone trying to give up real tobacco. Had it two weeks and in that time haven't felt the need for a real cigarette (feeling healthier too). One battery lasting all day which is great, also the vapour/throat hit and flavour produced at 3.8 volts is perfect for me. Thanks Jacvapour.
  • Reliable - by Grant, 23 October 2014
    If you've been vaping for a while and used different products you'll realise that some of the equipment can be very unreliable, not so with these, they work properly all the time and that's a massive bonus in my mind. Do yourself a favour and spend the extra few quid with this company and you won't be let down like I have been many, many, many times.
  • Excellent Kit - by Janice, 23 October 2014
    I bought this kit about a month ago, and although it takes a little getting used to at first, learning how to fill it properly etc, it is superb.
    A really really well made piece of equipment and the battery charges very quickly and lasts ages. Loads of vapour from it and, as usual with JAC Vapour, altogether good quality.
  • Fantastic kit - by Philip, 30 September 2014
    Bought the kit with the mini protank option. Very pleased so far, also own vox and nova tanks and this is miles ahead, no leaks at all and very pleasant vaping experience. Highly recommended.
  • Excellent quality kit- perfect customer service to match - by Max, 8 August 2014
    At first when I bought this kit, I was very impressed by the product. I used to use the cartomiser type and found them to be very short lived and gradually became frustrating due to constant changing of blank cartridges.

    First of all, the design and the look of this particular model is great. Sleek looking, slender and sophisticated- have already got many comments and people enquiring. The tank has a small window making it easy to gauge how much liquid is remaining. I chose the stainless steel finish which is very clinical looking and matches nicely with the battery.

    The batteries I am very impressed with, they seem to last a while even when on a higher voltage setting and charge very quickly and efficiently- having 2 batteries makes taking it out with you reliable for times that you are away from means of charging. The 4.8v setting gives a really nice throat hit which is about the closest to a real cigarette I've ever tried with an e cig.

    The tank is fairly easy to maintain and fill, it can get slightly messing sometimes when changing the wick but overall no problems whatsoever. I had an issue with the first tank leaking and without hesitation Jacvapour staff have replaced the tank free of charge and have offered fast advice; they are friendly, helpful and impressively professional.

    Smaller features add icing to the cake, small round rubber mouthpieces are actually really good considering the price and the default round metal one is secure and contributes to the overall design. The carrying case is sleek and perfect for travel.

    Definitely worth paying the extra; this is a reliable piece of kit.
  • Back to basics - by Barnes, 4 August 2014
    I have been a vaper for around 2 years now, and originally started with JAC Vapour on the V1P small ecig, this reliable little device got me off the real cigs and since then I purchased a myriad of different kits. I have seen most other kits fall by the wayside, egos and vamos, yet my trusty V1P still plods on (now used by my daughter). I purchased this kit about 6 weeks ago and it has become pretty much my go to despite having considerably more expensive kits lying around. What JAC Vapour does, it does extremely well, without any fuss. You can spend a fortune trying to get an ecig to do what this little ecig does day in and day out reliably and efficiently, and even although the ecig may be simple to use, it also has just about everything you'd need if you wish to tweak a bit more. I recommend this company and their kits to first time users and experienced vapers a like, they are a cut above the rest of the crowd, and I know it sounds gushy (I promise I have no affiliation with the company) but they feel like an old friend... Thanks for keeping me off the real cigs.
  • Excellent piece of kit - by Mike, 3 August 2014
    I started of with the V31 e cigs which was a great starting point and I still use these when in the car or out and about. But I wanted something for when I'm at home that gives more vapour and needs less charging. I contacted jac vapour customer support and was told about the 510 twist variable voltage range. I opted for the 650 mah battery's. In my experience its awesome, giving excellent vapour and easy to operate with its manual button. The tank holds loads of liquid and its nice to be able to see how much is left by the see through windows on both sides. All in all, I give this 5 stars and would recommend this to anyone. Its great to use and the variable voltage gives great control as to how much vapour you would like.
    Thanks JacVapour !!! Still a very happy customer.
