Ecigarette tanks are the core to every ecigarette. Typically these tanks are able to be filled (either by unscrewing the bottom or the top) many times over, making them vastly superior to the single fill tanks we’ve seen commonly in gas stations and the like. Tanks have come a long way in the past few years, most commonly allowing the coil to be screwed into the bottom of the device and then filled around. Tanks such as the one displayed above, the Kangertech subtank, are some of the most common and best on the market today, allowing to be easily filled and offer a wide variety of coils able to be used in them.
