According to the post below, it kinda works but the performance isn't 'supported'. The controller and other devices will randomly turn on and off based on power consumption. I've tried my best to get this product to work as advertised, but it just doesn't seem possible for it to work consistently. 12/24/2019: UPDATED TOK, after leaving a very negative review, I decided to solve this problem. MonoPrice is a reputable company and it was hard for me to imagine that they would sell such an obviously bad product. So after a lot of fiddling and a lot of other testing I figured out how this works with these connectors: You have to use super high quality Cat6 and in my case USB 3 for all cables and connectors. As I mentioned below I had a lot of lines and therefore have several types of Cat5/e and Cat6 on hand. Multiple specifications and the like. Only one worked. The ONLY I have found is: Cat6 Riser (CMR) 1000ft Black 23AWG 4 Pairs Solid Bare Copper 550MHz ETL Listed Unshielded Twisted Pair (UTP) Bulk Ethernet Cable, trueCABLEhttps://www . amazon.com/gp/product/B07C848GTK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 If you don't have a fixed pair at 550MHz or higher, the power supply just won't work. I've tested it at over 50 feet and it works great. The 500MHz below will not work and will not power the controller or other USB powered peripherals. For example: I tried this cable: Monoprice Cat6 Ethernet Bulk Cable - Solid, 500MHz, UTP, CMR, Riser Rated, Pure Bare Copper Wire, 23AWG, 500ft, Blue https://www.amazon.com/gp/product/ B016YS99X0 /ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Almost identical stats, and it does NOT work in ANY range over 17ft. I don't think brand is necessarily an issue, but the first cable can certainly handle slightly higher frequencies than the second and somehow makes a difference. The point is, if you buy this product and want it to work, don't skimp on it. cable.2019-12-23: I bought this to go about 30 feet from my basement to my 1st floor office. I have over 40 1GB drives at home, I have all the equipment and I know how to connect the cables. I ran this, tightened the bushings and ran some tests. This device just won't work beyond the 16.5ft base USB distance limit for POWER. For data it works great at 30 feet, but for something that requires USB power it just doesn't transmit enough power for the device to function properly. I did several tests, the main one was the controller xBox One S. It works great with power up to 17', after that it won't even turn on. I also connected a USB powered external hard drive to see if the power reaches 30ft and nothing turns on at all. I then had a few other cables of shorter lengths and tested various distances and around 17 feet. The device turns on, nothing more. I then tested each wire 30 feet away with a multimeter and found that the voltage and current are very low, but not enough to power the controller, hard drive, or other peripherals. Comments and questions on how some people have managed to get this to work at 100ft and I'd be very curious as to how that happened as I can't get past 17" in my testing. If anyone has any other suggestions for getting this to work I'd be interested, but other than that I wouldn't recommend this product and it doesn't seem to do what it promises beyond standard USB limits.
