I have the Motorola Flip Stand. Its not really a charging dock, its more of a stand to hold your device. It can hold it portrait or landscape. You can use any charger to charge your device while its in this stand. In fact you can use this stand for any device. It holds my Moto X & my Nexus 10 securely in portrait or landscape. I've also tried an SGS4, iPhone 5s, Nexus 7, Droid 4 & an HTC One M7. Works perfect for all devices. But, its just a stand. That's all. I find it very useful to securely hold my devices though. I have 3 of the stands. One on my bedside table, one in the kitchen & one in the family room. Amazon had them on sale for $18 when I bought them.
