Perfectly allows for extra components to synchronize with my laptop like my printer, second monitor, phone charger etc. great buy

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

Pros: Works as planned Set it up one time and never have to do it again Useful when plugging in extra USB when the PC or Mac has limited USB ports USB 3.0 - Faster data speeds Will power devices from computers USB port. Doesn't need power supply One device for all my USB needs. Cons: - Power Supply broke after almost 4 years of use. So when I removed the cable my computer all devices needing usb power (i.e. desklight, fan, charging of headset) stopped working. Need to purchase a new one. - Only one Power Port. For me, I want more USB power ports to use with my phone, tablet, fan, light, headset or other devices needing power. Overall a solid 4.5. I loved how simple it is and how it kept my desk cleared from USB electrical power plugs

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

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.
