Ender Chest

Ender Chests are blocks that can store items. Ender Chests function the same as normal Chests, except that their contents are shared across all other Ender Chests placed anywhere, even in different dimensions.

Ender Chests cannot be made into Double Chests and can be placed adjacent to each other normally. Ender Chests do not drop their contents when broken. Items placed inside will remain persistent even if all Ender Chests are destroyed, and can be accessed from new Ender Chests. Ender Chests have the same blast resistance as Obsidian, making them immune to explosions. They also emit light and a particle effect similar to that of an Enderman and Nether Portal. In SMP, Ender Chests have a separate inventory for each player, but they have an intended drawback: destroying one in SMP will only drop 8 obsidian, meaning another Eye of Ender would be required to craft it again

Trivia

 * Since items are persistent even when all Ender Chests are broken, the player can use them to recover items from anywhere safely, even if they destroy the chest.
 * Ender Chests can be very useful in Hardcore if the player is able to obtain the resources required to make one. At the cost of one inventory slot for the chest, the player gains another 27 extra slots, for a net gain of 26, adding up to a total inventory space of 62 different stacks you can carry.
 * Similar to obsidian and chests, Ender Chests cannot be moved by pistons.
 * A good tactic for moving large inventories using only one Ender Chest is to place it, place whatever you need inside it, break the chest, and then place it wherever you need to move the items to. The items will not be destroyed or dropped in the process.
 * Despite being made out of obsidian, the Ender Chest can be broken with any kind of pickaxe.
