A tank of a vaporizing device is described, wherein the tank may comprise an atomizer and a reservoir for containing a liquid adjacent to the atomizer. The atomizer may include a wick and a heating element, wherein the tank includes a barrier that separates the wick from liquid in the reservoir. The barrier may be at least partially permeable to allow for transfer of liquid from the reservoir to the wick for vaporization. The tank may include a connector coupled to the atomizer and configured to electrically connect the atomizer to a power supply.
