Review on 📱 UGREEN Micro USB 3.0 Y Cable: Super Speed Data Sync & Charging Cord for Micro USB 3.0 Android Devices - 3ft" by Cody Clark

I bought a similar USB-Y version but it didn't fully fit my Wii U console. I don't have to worry about that like I did with the other one, which means some of the data will come out on the Wii U. It does not bother me. Enjoy your Wii U backups on an external hard drive without changing drives or running out of space (Wii U supports up to 2TB of external storage).
