Review on MutecPower 50 Feet Active USB Extension Cable 2.0 Male to Female - Signal Booster, Long-Distance Active Extension/Repeater Cord 15 Meters / 50 Feet by Brandon Grzankowski

I bought this to use with my Oculus Rift and the info SAYS it should come with a power adapter for longer cables, well , I bought a 50-leg cable but NO AC adapter with it. I know that anything beyond a certain distance takes extra power to move data back and forth as it loses power over time. So I'm hoping the original seller sees this and asks me to send me a 5V 2A power adapter to plug in to finish setting up my VR setup for my kids.
