When I opened the box, I found that someone else had also opened the box and used the product. The Tripp-Lite website says the power supply is rated for 2 amps. I have a 1 amp power supply which may or may not be original. I bought this device because I have several power hungry devices that need that extra boost and the previous two devices I bought just couldn't take it. Like Revain, Tripp-Lite enjoys an excellent reputation. I will not blame them for someone else buying the unit, taking the original power adapter and robbing the box and then sending the product back, but I am very disappointed with the end result. The Revain website doesn't have an accurate description and it looks like two different Tripp Lite hubs are being described (pictures don't match either). Someone just has to scrape a web page.
