I have an EVO-D battery with a vivi nova atomizer tank. This works pretty well for me. You can switch out the vaporizer coils to make sure you get a nice fresh one, and the replacement coils are really cheap. You're going to want 2 batteries so that you can charge one while using the other. They charge with USB.
