Minecraft wiki entry for Transportation_methods, associated text: An ender chest is a variant of chest obtained with 8 obsidian and an ender eye, with the unique ability to share its inventory with all ender chests across the world (specific to each player). It can be used as a "bank vault" of sorts where all of your most important items are kept, as its contents are completely safe from being stolen. Alternatively, it can be used to deposit items from one location and have those items be immediately accessible from any distance in another ender chest. Furthermore, if a silk touch pick is kept on hand, the ender chest can be picked up freely (otherwise, 8 obsidian minus the ender eye is dropped), allowing for a makeshift extra inventory to carry around.
