I waited to see what anyone else said it could be since you posted it.
I have never seen one of those, but I will take my best guess.
I see three different options for that device.
1. You could potentially use it for e-ciggs. The old style that I started with in a sense worked in the same manner. I would often drip liquid into the cotton so it would drain onto the heating coil.
2. So you can add flavors to your oils? Or maybe just for stealth reasons and you add flavor, like vanilla and when you go to use it you remove it.
3. Some other type of thinner oil mixture to be used like a drip type e-cigg with diluted concentrate or infused concentrate. Infused with something like PG USP which is used in e-cigarettes.
That kind of looks like a cheapie, by first impression. You may prefer an Up Tech KISS cart. They are meant for the Persei, You may need a 510 to 601 adapter, which you can purchase at High Desert Vapes.
