muy util compre una laptop y solo tiene 2 puertos usb con este articulo puedo conectar cualquier accesorio hasta disco duro

I had so many peripherals connected to my PC Tower/Server that it would freeze on boot-up. I also had a USB line connected to a large safe for the data storage drives located inside the safe. After some research, I ordered two of these highly rated, Atolla, powered hubs. I removed all of the USB connections from the PC Tower/Server and connected everything directly to this self powered USB hub. I then connected the input of this self powered USB hub, to the USB connection on the PC Tower/Server. I placed the second of these Atolla, powered hubs inside our safe. There, it presently powers three data storage drives and allows for future expansion. This solved all of my USB problems with virtually no power drain on the system’s internal USB ports. This hub will work without plugging in the included wall-wart, power supply. However the added power boost of the AC connection makes everything work better. The individual power switches on each USB port is a great feature. One can turn off the unused ports. I can only see 2 negatives in the design. I wish that it had an in-line power supply with a regular electric cord. The included wall-wart, power supply is large and difficult to plug in to a power strip with other items. I also wish that the hub would automatically shut off when the computer is turned off and/or when there is no USB signal feeding the hub. In self powered mode, it stays on 24/7, which translates in to your USB peripherals being continually powered. Over all, this a great product. It is a major upgrade to any computer. Update: After using these self-powered hubs for a while, I would offer a tip. They do a great job but when using more than one hub connected directly to the same computer, I had a little glitch on boot-up. The problem was eliminated by feeding the second, self powered hub, from one of the USB ports on the first self powered hub. (daisy-chained) This worked much better than having both hubs connected directly to the same computer.

Working very well.

I bought this for my work laptop so I could simplify all the cables and connections on my desk and run several accessories through one hub. Right now I have my monitor adapter, external hard drive, Jabra speaker, printer, and LAN connection all running through this device, and it works perfectly. Setup was easy, including downloading the required driver. That took maybe 5 minutes, and another 10 minutes to plug everything in and clean up the cable management. My desk is much cleaner now, everything works correctly, and the individual on/off switches are a nice bonus. Very happy with this purchase.

I have two ,all are working good . No problem.
