The charger fits perfectly with the score 3 (USB 3) - but please note: It's really just a desktop charger with audio output. Whether this is a worth the money, everyone must decide for themselves. Positives: The back support is slightly longer than in the USB 2 version - should once Tablets come with USB 3, it may not be as unstable as in the USB version 2, when loading a tablet (eg Note 10.1 2014 Edition)
