Aspire Atlantis EVO Extended version sub ohm tank also features 22mm diameter and 4ml liquid capacity. It comes with an adapter and a 4ml Pyrex tube for larger tank capacity. It comes with both 0.4ohm and 0.5ohm Kanthal Clapton coils and provide different flavor. The top-filling design makes refill more quicker and cleaner. Double wicking efficiency, due to enlarged cotton exposure holes, is teamed with lower positioned wick points. This creates ultra-efficient juice flow and will allow high VG juices an even faster route to the coil system.
