1. Who knows what kind of liquid is in that clearo, or how old it is. It could have so much nicotine it makes you sick, and it could be "old socks" flavor for all we know...
2. You'd still need to go out and buy a charger for the battery, if nothing else.
3. You can get equipment similar to that in style, but better in quality, for $15 or so these days.
If you're really curious, I'd just go out and buy an Evod-style kit and some 0 nic liquid. Throw that topper away, and if you like vaping you've got some fresh, suitable liquid and a proper topper, plus you've scored a free spare battery...as long as you like lime green.
