both are KR808D-1..puresmoker one has a 5 sec cutoff on the
batteries.. vapor king is a 15 sec cut off..
puresmoker one is just the
batteries and charger..
Vapor king depending on kit is 2
batteries, wall charger, usb charger, pt, case and a 5 pack of cartos..
so yeah puresmoker is cheaper if you want just bare bones..
but yeah they're the same model so interchangeable...and hell with the right adapter you can even use a 510 atty on them
