Shelf Alibi

Hide a charging hub among the books

A hollow book for the bookshelf: put a USB charging hub or power bank inside, feed the mains lead out through the back and the charging cables up through the slot in the top. Phones and earbuds charge on the shelf with every cable hidden, and from the room it is just another spine.
