To be honest, we did not reinvent the AC adapter or USB cable; it is what it is. We simply chose a high quality UL certified full 2A AC adapter to make sure you can have the safest, fastest charging speed. The included USB cable is protected by a ferrite bead, also known as an electromagnetic wave-bouncer. The USB cable is 1.8m, or six feet, in length. Due to the uneven quality of AC adapters on the market, we strongly recommend you stick to the official Cloudious9 charging kit to prevent damaging your device and voiding your warranty.
