The Omny Box S allows you to use two phone cords in series to extend the social distance for you to charge your phone from a power outlet or USB charging station.
The "S" (Sierra) type Omny Box has a standard USB port and a USB type C port plug in. My LG phone used the type C cord.
In addition to the additional distance, the Omny Box line protects you and your data stored on your phone from "DIRTY" USB charging ports in public locations. The FCC is reporting that malware is being installed on public charging ports in an effort to steal data from your phone. Because the phone is plugged into the USB port there is no security preventing the transfer of data.
