Not very experienced about these things but I used a 510 for over two months. On the advice of a forum member I got a chuck. Actually I got two, a regular and a little one. The regular one gives you the option of 6v or 3.7. The little chuck is 3.7 only.
I vape mine at 3.7...tried the 6V, like it but need to fine tune it and probably go the direct drip route, so that is for another day. Even if I never go to 6V, I am glad to have him. I still can't decide which I prefer better, big or little.
I had every intention of using my 510 attys. Best way to order is with a 510 fitting but get the adapters. I decided to try cartomizers and love the simplicity and consistancy of them but my 510 stuff will still be able to be used.
I've had it for one week today. Love the thing and I am five days with no analogs whatsoever because of it. I don't ever see myself going back to a basic battery pv. The fun added plus, no one has one like it. The customized graphics make it even more of a hoot.
It does take a while to get but worth every moment!
Edited to add on the
batteries....I am the worst battery student, I've been schooled over and over but only retained enough info to get my batteries ordered and use the ones I have but there is a whole thread dedicated to chucks and batteries in the Thagbuilt vendor section of this forum and there are a few members who can answer all of your battery and voltage questions and then some.
