    Grab a bargain, 2x JAC 510 900mAh Twist batteries for just £15.99! Plus, a FREE 4.2v charger and faux leather carry case (RRP £12.98) with every purchase.

    Offering the greatest capacity of any of our variable voltage models, JAC 510 Twist 900mAh batteries clock in at 112mm. While lifespan does vary depending on usage, we'd expect each of these batteries to last for around 8 hours of average use per charge (less if used at full power). So, with the two supplied in this twin pack, even the heaviest of vapers won't have a problem getting through the day on a single charge.

    When paired with the Kanger Evod 2 total length will measure around 174mm.

    To use a Twist battery, the user must push and hold a button while inhaling. It may seem a little strange to start with, but the motion quickly becomes very natural. These models also offer variable voltage, allowing the user to adjust the power level on the fly. Simply twist the disc on the bottom of the battery to set the voltage from between 3.3-4.8v. Higher volts will produce more heat and vapour, but may affect flavour. Battery and e-liquid consumption will also increase at higher power levels.

    JAC 510 Twist batteries require a dedicated 4.2v charger, which you'll receive when purchasing this twin pack!

    Please note, this battery twin pack does not include a tank or e-liquid, so if you don't already have some, don't forget to pick them up to complete your kit. The Evod 2 or Mini Protank 3 are both great choices to use with these batteries.

  • Not bad - by caroline, 12 September 2016

    Got these when I couldn't get the 810 anymore. I can't get on with them. So I have now ordered the b series. These are always leaking and the battery's don't last long.my old ones lasted much longer.

    I have used the V31 Batteries in the past, but I wanted something that I would be able to use with other items. With the 510 connection, these e-cigs are easy to personalise. I couldn't reccomend them highly enough. Long battery life and reliable.
  • Premium Quality Kit - by Darren, 22 November 2014

    I have used other cheaper 510/ego products before and whist this product is similar everything feels a lot more premium.

    I brought the stainless steel with the optional mini protank 3 (in which i highly recommend doing for the extra £4)

    The batteries like i said are of solid construction and feels really nice in the hand. The 900mah capacity is great and lasts me the whole day (if not longer) so with the 2 batteries in the kit you are never going to be caught without power! The VV option is great if you feel you are not getting the vapor production you like, you can crank the power up a bit and taylor it to your needs. 1 little criticism is the power button is a little small and i would have liked it a bit bigger but it does do the job and its the standard button on most of these type of batteries.

    The Mini Protank 3 is just an awesome tank. The dual coil helps out a lot with the vapor production and the e-jucie tastes great. The tank itself is well constructed as you would expect from KangerTech and you will not have to buy another! just replace the atomizer from time to time.

    If you are just starting out with vaping and are thinking of giving it a serious shot i would recommenced this kit as you will be set up for a long time. In the past i have wasted a lot of money testing out different products, if only i knew what i know now! all you need it a good tank and a good VV battery... This kit delivers just that
  • S solid starter kit, but just starter kit. - by Ronnie, 7 October 2014

    What is bringing my grade down a bit is two things, the tank in general and the black surface in particular.

    Let me just say first though, this vapour system brings the real deal to the table, it performs with highest remarks and it is really reliable, so I think this kit has good value.

    The problem with the tank is that screwing and unscrewing is tedious. It is very easy to tighten it too much and you really don't know when you do. At the same time, you're doing it so liquid won't leak. It would be better to open up the tank for refill on the other side, far from where the battery connect to the tank, but this is almost on the same place without anything helping you to grab on to anything. You just have a glossy metal surface to work with.

    Second think is actually the blank surface in black colour, it doesn't take long until it starts showing scratches.

    This could really need some rework. I might be asking for much here with the color thing, but the screwing/unscrewing really could need a fix, something for your fingers to get a better grip.

    I recommend this starter kit for great value if you can live with the cons. What I did was that I bought extra batteries with a metal surface as well as new tanks, such as the Pro and Pro Air which I have reviewed on their pages.

    JAC Vapour really stands out amongst the competition for this price range.
  • What a difference the "Twist" makes. - by John , 4 October 2014

    This only arrived yesterday and hasn't left my hands since (ok i slept and it did then) I vape UK menthol 18mg and i've been a devout Vgo2 crystal lover since i got one but this 900mAH twist is without question the best vape i've ever had. the 900mah battery isn't as heavy as i thought it would be for it's size but feels solid, the evod2 tank it comes with holds a great amount of juice the drip tip is well fitting and feels good when in the lips, over all the ape from this poduct is excellent not too airy not too gunky(if you know what i mean) and so far there's no sign of liquid on the battery connection and i've been vaping HEAVY!! Can't wait to try it with some new flavours.. Thanks JAC

    Ordered this wed eve arrived fri morn private courier so excellent service.I bought this as a present for my wife who has used cheap rubbish products for years so when this arrived she was immediately amazed at the quality of the whole product.The battery power the speed of charge and its duration was also impressive.I can honestly say like many e-cig users she has a obsession with the strength of the throat hit and was not convinced when i said some people find a 1:5 ohm coil and a 900mh battery turnned on full too much but when she tried it the moment she coughed i knew she'd love it and because it's a variable voltage model it meant she could fine tune it.If you want the best without paying over a £100 this is the one!
  • Amazing - by Nick Parfitt, 6 August 2014

    My twist 510 900mah just arrived after about 24h free delivery. And it's amazing. I ordered the banana milkshake flavor to vape with it and it comes out so smooth and with a lovely warm mass of vapor. If this is what the best has to offer then I'm really impressed. Thanks Jac Vapour! (If I get any problems I will be sure to update and comment on customer service!) :) :)
  • A++++ - by Duncan, 2 August 2014

    Without a doubt one of the best e-cigs on the market today. As of late I bought this along with the Totally Wicked Odyssey VV (a much more expensive product) and I have to say, the Jac 510 is the better e-cig.

    I have been vaping for almost two years now and have tried a good number of different products, and this is what I would recommend to anybody who is thinking of taking up the hobby and cutting the cigs, or a current hobbyist looking for a solid model.

    This pen summates why I love Jac products - it is simple, and damn good at doing what it is designed for. No go faster stripes or wacky light up tanks, this will give you a good solid vape every time you hit that button.

    As with all litium-ion batteries they will decline over time, however these are giving a good 2 days of heavy heavy use right now. I used to have a VGO2 and the batteries there lasted over a year with heavy use, so I have no doubt these ones will too.

    Note to users - sometimes the "turn off" feature can be a little bit picky, but just keep clicking the button until it doesn't light up any more.

    Highly recommended
