Customer Reviews for the JAC 510 Twist 400mAh Twin Battery Pack (Free Charger and Case)

  • 400 - by sandra, 6 June 2015
    I have no idea how to use this. The indtructions are sparse and seem aimed at people who are familiar with vaping. Im not. Id think for the price they would give proper instructions. Iv wasted most of a bottle of juice trying to fill it and iv got it all over me too. I still havent managed to get it working. Been on you tube looking for a tutorial but cant find one. Really dissapointed and now wanting a fag too and praying i havent damaged the unit as this was a lot of money for me to pay out. ..... JAC Vapour Ltd: I am sorry you have found this difficult to understand, there are full instructions on the inside of the slip the kit comes packaged in, you can also contact support on (they will walk you through starting up) or watch youtube channel for tutorials.
  • Nice looking... - by Jaqs, 26 May 2015
    I bought this but I am rather disappointed with myself as I didn't compare what I had.. I had a Cirro3 which was great but I wanted something where I didn't have to keep buying the clearomizers after a couple of weeks! so why am I disappointed? I feel like I am forever charging the batteries on this my Cirro3 lasted all day without a charge and these only last max 4 hours which is pretty annoying, so I should have checked I needed a 650mah battery!! live and learn if your happy to keep charging then this is great as it looks good and is handbag friendly!....................JAC vapour Ltd: you are indeed correct the Cirro 3 is a larger battery at 650 mah, if you are within 2 weeks of purchase we have a free return policy, you could check with customer service and see if they are able to get the smaller batteries exchanged for the larger batteries. the batteries you have are variable voltage which your cirro 3 wasn't, variable voltage adds size, also if you are using the higher voltage of 4.8v it'll run the battery out quicker. So if you want an exact match to what you had previously the 650 Ego is what you require, if you want variable voltage then the Ego twist 650 is what you require (this will be 10mm longer than your standard ego), or you could move to something like the SERIES-E which is thicker but the same length, the SERIES-E is 1000mah and has VV and matches the 650mah standard ego in length but it 18mm in diameter.
  • Too Short Vape Time - by Geoff, 14 January 2015
    I bought these as I didn't consider myself as a big user. However, I have to use two batteries to get an evening's use. I had them replaced with new ones, but the usage time is the same. I wish I had gone for the 650's now... ..... JAC Vapour Ltd: Hi Geof, If you are managing to go through 2 batteries (900mah) in an evening then you are a pretty heavy vaper, most users go through about 1000mah a day, a very heavy user (constant vaping all day will use 2000 mah) but that is very heavy use. If you contact support you do have a 14 day return period, however I would suggest going for something like the SERIES E which is 1000mah a bit wider than the 400mah twist, but the same length and also has VV. I think the 650 will also be too small.
  • Awesome +++++ - by simon, 29 November 2014
    Just had this delivered this morning and I've got to say I'm very impressed :) After using the Vgo2 and crystal tanks for around a year i decided to upgrade and I'm glad i did. The build quality is excellent and it works very well!! Loads of vapour and flavour i would highly recommend this to anyone! Top marks Jac
  • great kit but..... - by James, 31 October 2014
    Like the new mini pro tank with duel coil can't fault it but then I come to the twist batterys 400mah is ok.... Only one little problem on the twist battery is the lowest starting voltage = 3.16v and highest = 4.76, it's not far off the stated 3.3 to 4.8.... It's just the markings of volts at the bottom are out of sync. Yes I've only just tried them and fully charged them before hand so no fault on my behalf. Well recommend over the vox that I use to have
  • excellent - by stewart, 20 August 2014
    bought this last week and love it.
    ive used normal cartridge cigs since January but decided to try this mainly for the flavours available.
    apart from a little hick-up with the batteries (sorted very quickly and easily but customer service) its been very good, so good infact I have now bought 1 for my wife and she loves it too.
  • Class - by Brian, 27 June 2014
    I've recently upgraded from the P1 PCC Kit pro to this awesome Kit. Absolutely fantastic move its pure class. Not to bulky and gives a fantastic vape and just looks fantastic.
  • Amazing bit of kit - by CrybabyJ, 7 June 2014
    Just had this dropped off by Yodel and it's smart as hell. Am sitting annoying the ball and chain by blowing massive smoke rings at her. For a VV kit this is very small and it performs well, not had to recharge yet and I've been using it all afternoon pretty frequently.. maybe a bit too much.
