For an eGo or 510 (3-piece systems) - 2 batteries, 2 atomizers, 5 cartridges, a charger, and some refill liquid is the absolute minimum. You'll need more refill liquid than you think. If using a 2-piece system like a KR808 - 2 batteries, 5 regular ('cool') cartos, 5 LR (the 'hotter' type) cartos, a charger, and some refill liquid if you fancy DIY refilling. The eGo or 510 can also be used in 2-piece mode. At some stage (probably the sooner the better) you will want to refill your own carts or cartos instead of having to buy new pre-filled ones. You may need filler foam for the cartridges (cartos don't need this, though), but in a pinch you can use other materials. Blue aquarium foam is reckoned to be the best filler. It has to be emphasized that this is a rock-bottom try-out quantity - experienced users generally have at least five times these quantities so that they never run out at work, in the car, or at home.
