The Crown 4 tank features a host of improvements from the previous tanks in the Crown series, including a sturdier construction and a simplified top-fill e-liquid system. The Crown 4 tank also boasts innovative, fully patented self-cleaning technology in which the coils are able to absorb excess e-liquid into a separate condensation chamber which can then be vaped later on. You can now make the tank even better by adding on this Adaptor to make the tank even bigger with this bulb glass and extender.
