The only extra things you'll need are an atomizer or cartomizers, cartridges too but only if you get atomizers, and juice of some sort. That will get you going. I'd buy spares too. I'd also recommend you buy at least 40ml of juice in different strengths and flavors. That will allow you to figure out what nicotine level you need, and what flavors you like or don't like. It will also keep you vaping for a while before you have to order again.
