Query: It needs power

As another reviewer said, it needs power. I wished I had noticed that before I bought (my bad). I was used to an Apple HDMI/USB adapter on my old iPad 2 that didn't need to be connected to a power outlet. Now with my new iPad A1822 that has the lightning connector I needed a new HDMI converter. The one time I used this adapter with FaceTime to my TV the sound was delayed and didn't match the person and later the picture froze of both myself and the other person even though the iPad showed live action. It's going back.
