The ELeaf Pico is a mod- if you get the Kit it will be the Melo tank- that does not take Kanger coils, but many others like the Melo,Aspire Atlantis and Triton, Tobeco Coils!
If you get just the Pico(mod) you would be able to put any tank( like your Kanger) as long as it is 23mm and smaller because of the battery cap!
You would also need at least 2 - 18650 batteries and an external charger- so you can easily swap out the beat battery with a fresh! I carry my spare battery in a small plastic battery case!
