Welcome-
That is Mistics proprietary tank- I do not think an Evod will work! I don't think you can replace the coil either- you throw out the tank when the coil burns out! Yes you need to use high PG with that tank, I think 50pg/50vg would be ok- VG is too thick for that coil to wick properly! I actually used Mistic bridge kits
https://www.misticecigs.com/product/mistic-bridge-starter-kit/ and their Cool Ice eliquid and cool ice cartridges when I quit smoking. The American Tobacco eliquid wasn't too bad either. Their eliquids are made in the US.
Nic is 24mgs but I needed that to keep from smoking. I see that they have something similar to the Juul, maybe try that
