Question: Would this run a high powered (alfa 2000mW)  wifi adapter?
Document: Did not work with high power draw Wifi adapters such as Alfa. I will try it in conjunction with a powered Hub,  see if that works and update. Update 5/20/13; would not stay connected more than 3 seconds with "Belkin Powered Hub". Two Stars.
The item works as advertised; I suppose my biggest beef is how complicated getting Bluetooth to work within Microsoft Windows 7 is. After I got it to work (Win 7 issues), it has worked exactly as I wanted it to. I have this run from my office to my TV room to run a Bluetooth Keyboard; this coupled with my long HDMI cable had really made my computer a full multi-media station.
plugged it in and away we went, no loss of performance. Would recommend this item, will see how it works in the summer when it gets hot.
This item does exactly what it needs to. It will successfully add 50' to whatever USB cord you have. I would suggest buying one if you need to do that.
I bought this thinking it would match up to the Xbox kinect as an extension cable. It does not work with the xbox. not sure if it was advertised as such. as a consolation, it shipped quick.
This item was purchased to be used as an extension cable on a USB Webcam....I was more than pleased with the result...Other regular cables which i tried failed to meet my requirements...I would recommend this unhesitatingly
My computer would not even reconise the product. I bought this to get my wi-fi internet signal closer to the area where it comes from and it doesnt even work. My netgear cannot work through this cord.
waste of money and time. thought it was going to work for a e-net antenna. read about it before I bought this to make sure it wasn't going to be a problem. yeah that didn't work out! lol  but it did work for a web cam I had laying around so I got to watch to grass grow....smh
length was what I needed and this fit the bill, cost was good and cable is made well. I will buy more when needed.
Works great no issues, for the price its a great buy. I use it regularly and in many conditions, it very reliable.
Answer: I don't think so I tried running a couple of devices directly off the cable  and it actually would fail, it works great connected to a powered usb hub
