Ender Chest

Ender chests are a type of chest that can store items, although the contents of an ender chest are bound to the player opening it, not the ender chest being opened, regardless of where it is (or what dimension it's in).

Obtaining
Ender chests can only be reclaimed by mining them using a pickaxe enchanted with silk touch, or it will drop 8 blocks of obsidian.

Natural Generation
Ender chests naturally generate in end cities.

Usage
Ender chests can be opened by pressing. If a solid block is placed over an ender chest, it will not be able to open.

Ender chests can be used like chests, except all ender chests in the world share the same inventory, including in separate dimensions. The ender chests' inventory is also separate for each player; consequently, items stored in an ender chest cannot be taken or seen by other players.

Ender chests contain 27 slots for storage, and can be placed next to other ender chests without joining.

Ender chests cannot be moved by pistons and will not interact with hoppers, droppers, or comparators.

Ender chests emit a light level of 7.

Block entity
An ender chest has a block entity associated with it that holds additional data about the block. The block's block entity ID is.

Trivia

 * An ender chest's particles exist only in the 1 block radius around the chest, so if the chest is placed next to a wall its particles will not be seen on the other side.
 * Unlike chests, changes to an ender chest's name are not reflected in its inventory GUI.
