1. A method for filling a cartridge used in a portable vaporizing device with a vaporizable product, wherein the cartridge comprises a vaporizable product receiving chamber configured to receive a vaporizable product therein and having upper and lower opposing ends, one or more internal heat-conducting surfaces within the vaporizable product receiving chamber and extending in between the upper and lower opposing ends thereof, and a porous valve element, the porous valve element being configured to at least partially vaporize the vaporizable product as it exits the vaporizable product receiving chamber by passing therethrough, the method comprising:
heating the one or more internal heat-conducting surfaces of the vaporizable product receiving chamber;
introducing the vaporizable product into the upper opposing end of the vaporizable product receiving chamber, such that the vaporizable product flows along the one or more heated internal heat-conducting surfaces of the vaporizable product receiving chamber towards the lower opposing end of the vaporizable product receiving chamber; and
optionally, pre-heating the vaporizable product prior to introducing into the vaporizable product receiving chamber.
