Garmin GDL 52 Portable SiriusXM/ADS-B Receiver

Can i run the gdl 52 off a usb power pack for more than 5 hour battery life, or does it have to be plugged into a 12v power socket to run?

Unit only comes with a cigarette lighter charger, and a charging cable with a standard usb to micro usb plugs, so what wall charger is recommended?

Where does the XM show up?

How aboout in pressurized aircraft will it work
