The tiny little thing has an internal reservoir to refill and has replaceable coils. It looks really cute. Definately a starter unit and it's about $15, usb charges in an hr.
That sounds kind of like the fairly new Kanger TOPEVOD starter kit. Early last week I ordered 2 for a couple friends who finally want to try vaping. Many websites sell them, but descriptions of the size are all different, and some are actually wrong. It's really a total of 5 1/16" tall with the tank on top, and is 14mm in diameter (reg. eGo & Evod diameter). It's a 650mAh Evod battery and the tank is a 1.7mL, top fill, TopTank Evod (it's sooo cute)! Uses replaceable coils - same ones the PT & PT 2 & the Minis of both take. Got those 2 kits at Ecig.com since I had a small credit there I wanted to use, and the kits were only $11 each there.
When those came in the mail, I decided I loved the looks even better, especially the little tank on top. Got with friends & showed them how to use them, to change the coil, to refill eliquid, charge them, etc. Tried 1 of them with 1 of my drip tips on it. It has 3 airholes on the tank, and is alittle airy for me, but is still a nice vape! Told them a hole or 2 could be covered with a tiny piece of clear tape to tighten the draw a bit if they wanted to, or not.
I decided to order - a couple for me (great stealth vape size) and a few more to put away for other new vapers in the future. Had another credit, at MFS, who has them on Sale for $10.97 each. So...they're expected in this coming week!
