Anker PowerPort Cube | $21 | Amazon | Promo code ANKERA27

We’ve seen power cubes with more ports and outlets from other manufacturers, but Anker’s take on the category has a few nice touches. While it leaves one side of the cube empty, it does come with adhesive pads that let you mount it on a wall or underneath a desk, and its standard 5' power cable is detachable, meaning you could swap in a longer or shorter one if necessary (Update: Sorry, I was wrong about that).
