The Belkin 3-Outlet Power Cube with USB-A is the latest in a long line of competitors looking to bring AC and USB power closer to where your devices are, instead of adding plugs and jacks under one writing desk. The compact cube features three AC outlets and three USB-A charging ports connected to a 1.5-meter power cord. The cube can sit perfectly on top of a desk. Placing the three outlets and a set of USB ports on different faces of the cube means you can use each outlet without interfering with the others. Cube measures approximately 2.5 inches on each side.

The simple design comes with a low list price of $24.99. But Belkin, forgive me, has cut corners in the interest of price and small size.

To reset it, you need to remove the power load and then insert a paper clip into a tiny reset hole under the cube to reset it.

The three USB-A jacks have better limits: they can output up to 18W between them, enough load for single devices (which often can’t exceed a 12W draw) or even three connected at the same time that draw 6W each. That said, it feels strange to offer a modern power device that doesn’t offer USB-C support with at least 15 or 20W.

Buyers should also be aware that this is not a surge protector. Belkin notes that the unit protects against “short-circuit, overload, over-voltage, over-current, and over-temperature situations,” but other than the over-current situation, which trips the internal breaker to reset, Belkin doesn’t provide details on how those protections work. they express.
