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

  • Great offer - by Bathsheba, 10 March 2018
    Although I already had a few of these batteries I couldn't resist stocking up with this offer and it is ideal for travelling. Still one of my favourite batteries despite trying others (which have tended to die long before the Jac batteries!). 10/10 for Jac quality.
  • Thank you to the team - by Yolande, 10 February 2017
    Further to my previous review, I took the advice of Customer Services and regulated the adaptors for use with the cartomisers and it worked. I still prefer the auto batteries but would like to thank you the team for their help and assistance in this matter.....................JAC Vapour Ltd: Thanks for the review and I'm glad you are sorted for now, we are currently working on a new auto model so we will have alternatives some point this year.
  • Disappointed for the first time. - by Yolande, 8 February 2017
    I bought the twin pack Jac 510 manual and decided to stick with the cartomisers which I have been using with the auto batteries. Also bought the adaptors. I found that after the first fill of the cartomisers, the batteries do not work ie do not produce any vap. I received replacement cartomisers and adaptors but the same thing happened. Not impressed........................JAC Vapour Ltd: I can't be 100% but this sounds like an issue with the adapter. The adapter is adjustable in that you can move the height of the connector to make a new connection, you do this by screwing the internal bit of the connector, it sounds like you have maybe not got a good connection. The other thing that can be the case when moving from the auto to the manual batteries is the 5 button lock, if the batteries are not lighting up at all when you press the button then this is the issue. When charging manual batteries they will set to locked in some cases, to unlock the battery you need to click it 5 times quickly in a row. I neither of these fix the issue then please contact customer service again and we'll sort this out.
  • Good for 2 months until it broke suddenly - by Vernon, 5 April 2016
    Was enjoying this starter kit, but the screwing/unscrewing system is massively flawed. For the price I expect a quality piece of kit, not one that is quickly made unusable when the battery suddenly locks in - I've tried everything to undo the screw, with no success (other than scratching the outside of the formerly nice finish). Very disappointed won't be buying from this site again.................JAC Vapour Ltd: Are you saying the tank has been over tightened and is now unable to be undone from the battery, if so this can be fixed easily. When using an ecig nothing should be more than finger tight, if it really can't be undone then you can return it. I may be misunderstanding the issue. If the base is stuck on the tank then a good trick with anything like that is to use a rubber band to get traction, or if the top of the battery has a fault then we'll replace it for free, either way you need to speak to customer service, so I'll get them contact you.
  • Great Starter Kit! - by Anna, 27 February 2016
    I got the Black kit with Evod2 tank. It's great looking and seem very sturdy!
    I was a total beginner when I bought this kit. I think I was quite lucky with the choice I made, I only wish I bought a bigger battery, perhaps the 900mAh instead, but I'm very pleased with this one anyway.
    I don't really notice much difference between the supplied coils, so I use either 1.5 or 1.8hm. I prefer the V2 coil as the V1's rubber part is in the way of the window so you can't see how much e-liquid is left.
    I didn't really take to e-cigarettes at first, so I didn't use it much in the first few weeks, but I persevered and now I have 1 roll-up every 2 or 3 days.
    I have had this kit since November 2015 and even though both batteries have now died (first one died a couple of weeks ago and second one died yesterday) I'm still giving this kit 5 stars.
  • Good - by Amy, 20 October 2015
    Great step up and has done me well.
    I'm ready for the next step up now but this has been well worth the money and done its purpose.
    No complaints.
  • Great step up for vaping at home - by Emily, 28 August 2015
    A friend gave me this, I use it at home in the evenings when I find I vape a lot more. I use it with 6mg menthol liquid and it's a lovely alternative to my v1p. I nickname it my 'crack pipe' as it's obviously a lot bigger than the v1p but it's actually very sleek looking.
    My only bug bear is that sometimes it leaks a bit onto the battery connector so I have to periodically take it apart and clean the connection. I think maybe I fill it up too high. It wasn't producing vapour properly today, I think I may have filled it a few too many times so I have ordered some new coils, which are also a bargain. All in all I am chuffed with my present, and next am planning to get the bigger 650 batteries. Thanks Jac, still off the stinkies and chuffed to bits x
  • Good upgrade from cig-a-likes - by Judith, 4 August 2015
    This ecigarette produces lots of vapour and the battery lasts a long time. Good size and good replacement for cigarettes.
  • Love it... - by michelle, 20 January 2015
    I originally popped on to the Jac website to order a new crystal tank but I just had to have a nosy around, then I came across the 510 range. They sounded great and I was liking the idea of bottom filling with no long wick getting all manked up. So I went ahead and purchased this kit, got the stainless because I wanted a decent tank, I don't like the crystal tanks at all, sick of them leaking.
    This kit ticks all the boxes for me hence the 5 stars, I've been using it for about a week and a half and I'm really happy with it, I can't see a lot of difference between the 1.5 and 1.8 coils though and I get on fine with both, I didn't have to change the coil for just over a week and I filled the tank more than 10 times so really pleased about that. However I am using more juice with this new kit but I guess I can live with that.
    So overall very happy at the moment with my new kit.
  • Nice but a bit small for me. - by jack, 22 December 2014
    I like the kit and was looking for something bigger than my V1p kit which this is but it is still a little small for my liking. Have since moved to the 900mah battery and they perform the same just the 900mah lasts me all day where the 400mah only lasted me half that.
