I didn't realize this was a third-party charging cable when I bought it for our Wii U gamepad. It charges the gamepad, but emits a worrisome high-pitched hum when it's plugged into the wall, regardless which outlet it's plugged into and if the gamepad is attached and charging or not. It makes me wonder if it's a bad quality and could possibly cause damage to our gamepad. We were leaving for vacation when this arrived, so we've used it for about a week, otherwise I would have returned it. I plan to purchase an official Nintendo replacement charger soon.
