Nice product which solved a problem of needing USB power clamped to a very thick work table. Most power strips with a clamp do not accommodate thick tables between 1.75" and 2" so I was happy to find this one. Successfully provides power to all my USB devices even a laptop (although charging is a bit slower compared to the OEM power adapter).
