rudukai13, I would recommend you go to Vapor4Life and look at their starter kits. (all they sell are Kr808D-1's) Buy one of the kits. If you are going to parties and concerts, the PCC (personal charging case) is ideal (they have the Vapor King Mini PCC kit, which comes with one battery only, but you might want two so you have a back up battery). If you go this route, you should eventually get an extra battery and wall charger.
You only take one battery, 2 cartomizers (which fit in the case) and go. Screw the cartomizer on the battery and vape away...when you're done, remove the cartomizer and screw the battery into the little charging unit and it will keep your battery charged and ready for your next vaping session. It's convenient, slim and it fits in your pocket.
Don't get the Diamond series batteries if you want a manual battery, as those are all automatics. But I've never had any problems with noise affecting any my auto V4L batteries. And since it's in the case charging, instead of in your pocket, it should not be a problem at all.
V4L also has a wide selection of nice flavored Cartomizers that you can get with zero nicotine. If you want to be able to vape discreetly, like in areas smoking isn't allowed, then you can get a stealth battery with no led. Go to the website, and see for yourself (
www.vapor4life.com). Their customer service is outstanding, and you'll have one vendor to deal with, and one stop shopping for all that you need.
