Review on 🔌 YOUSHARES Interchangable Power Charging Adapter: Ultimate AC Power Supply Cord & Adapter for Nintendo WiiU Gamepad by Steve Harris

When I bought it for our Wii U controller I didn't realize it was a third party charging cable However, the controller makes a high-pitched alarm hum when plugged into the wall, regardless of what outlet it's plugged into and whether or not a gamepad is plugged in and charging. So I'm wondering if this quality is bad and could damage our gamepad. We were on holiday when this arrived so we used it for about a week otherwise I would have returned it. I plan to buy an official Nintendo replacement charger soon.
