All vision ego clearomizers have a 510 connection to the battery and the cone/skirt that surrounds it just covers the ego threads. Heck I can even use my tiny 88mah Blu Cig battery with my vision ego clearomizers.
P.S. I have and tried the 3 different versions of the vision ego clearomizers and IMO the replaceable head version is the best is flavor, vapor production and ease of use.
