Review on Cable Converts Digital Signal Analog by Nikith Brewster

Tried to convert the HDMI input to an RCA input but didn't have a connector for a USB connection. Obviously it needs USB power because when I plugged it in it cut power from my HDMI signal splitter and all my HDMIs went dead. Why wasn't it included? I saw in the instructions in the box that there is no USB plug included. Why sell a product that requires USB power and doesn't include a wall plug? I recently bought another HDMI converter and it came with one. It will probably cost you 25 cents to turn it on. You need to sell products that have everything you need, or at least state in the description that you need to buy one. We as consumers can then decide whether to buy your product or buy another adapter that already has it.
