Hello and welcome to the forum ry2d2
You can't go wrong with a passthrough.
You have a good set-up there with a pcc to vape one and charge one outside the house, and a passthrough at home. I use a passthrough all the time I'm at my computer and frequently take it out too because I'm certain that it's fully charged when I unplug it.
As the others have said, all your 510 atties cartos and clearos will fit; I'm not sure what your "puff tank" is, but if it's a 510 connection then it will also be compatible
I would recommend that you take the plunge and try some e-liquid flavours which are not tobacco, like raspberry or coffee, or one of the more exotic dessert-type vapes... you will probably be very surprised at what tastes great in a vape... take a look on the flavour discussion boards for some ideas about what you might enjoy.
Congratulations on your new hobby, have fun with it !
