I'm about to order my first Provari.....yay!! I'm going for a mini and want the extension, as well as some other accessories. I see that the kit has a 2 unit battery charger and a Pro tank. I'm more interested in having the Pro tank 2 and some other branded tanks from different vendors. Am I better off just buying each item individually and getting a 4 unit battery charger, or is the savings by going the kit route really worth it? I travel long distances several times a year by car so the battery charger and car adaptor are crucial. Also, I'm thinking white with green display screen.....or purple??....decisions decisions!! I love color in my tanks and drip tips. What color do some of the women vapers out there have? It must be so easy to be a guy and just go black or silver!! Thx!
