This question is very difficult to answer because there are many options and different people have different needs. At the base you will need a power source, a atomizer, liquid and a charger. I will go through some options here and weigh pros and cons. All of these links will be to http://www.fasttech.com/ just for uniformity. The Cig-a-Like: https://www.fasttech.com/products/0/10004396/1352101-510-t-usb-rechargeable-180mah-electronic Pros: Small, Friendly to new user. Cons: Not a satisfying hit, build quality, battery life span. Similar items: BLU Cigs, White Cloud Cigs, V2, Enjoy Thoughts: Almost every new vaper wants to start with one of these because it looks like a cigarette. The vape experience is pretty miserable though and many people move past or stop using these with in the first week of getting one (if not the first day.) The Ego: https://www.fasttech.com/products/0/10005271/1489402-evod-twist-450mah-variable-voltage-rechargeable Pros: Small, Friendly to new user, Extra battery life Cons: Build quality, battery life Similar items: Inoken V3, Vision Spinner, Winder, Aspire CF Thoughts: This is the most successful device for converting new vapers. The vape experience is decent much better than the Cig-A-Like and with many of the Ego's you can adjust the power to some extent. You will often need 2, one to vape and one sitting on a charger. These can be found in many gas stations and mega marts. The VV/VW Mod: https://www.fasttech.com/products/3...f-istick-20w-styled-2200mah-vv-vw-apv-box-mod Pros: Much more durable than the 2 prior, excellent vape experience, fully adjustable, able to grow with you into intermediate levels of vaping. Able to accept many atomizers. Cons: Unable to sub ohm on some units so make sure you get a tank that is compatible. Often needs external batteries and more expensive chargers how ever many are avalible with interal batteries. Similar items: iStick, Cool Fire IV, Sigelei 150 Thoughts: This is what I recommend for any new vaper. My go to recommendation is the Sigelei 150 as it can grow with you as they are able to vape as low as 7 watts and as high as 150 watts and can accept almost every type of atomizer. Even if you progress past them they make for an excellent back up device. They are everything most vapers need. The Mech: https://www.fasttech.com/products/0/10005773/1700803-nemesis-style-mechanical-mod Pros: Able to run High power rebuildable atomizers, Simple mechanical connections with no circuit boards to go bad. Cons: No level of protection, Advanced build knowledge needed, no level of adjustablity. Similar items: The SMPL, Hamond Boxes, The Cherry Bomber Thoughts: In the hands of the experienced vaper these can be some of the most satisfying devices, but for new vapers they are a bit much to take in all at once. It would be like handing a 16 year old the keys to a Ferrari. A Ferrari is a wonderful machine but at the same time it is not a great first car... Batteries: One suggestion is to get the best batteries your device is compatible with. Batteries will grow with you an extra dollar or 2 per battery can go a long way. Some popular batteries are MXJO (yellow), Samsung 25r (baby blue), LG HE4 (red), Imrens (Purple). Now that we have the power plant out of the way next to to put something on top of it to vape.
