John: How much electricity is the cable providing John? There's still some debate about this, but we had one listener, Hughes 84 offer this. It looks to be about 10,000 to 15,000 milliamp hour battery, which are 3.7 volt cells. So it's 37 to 55 watt hours with a 2.5 hour runtime that's 15 to 22 watt average power draw quite low for hardware and processing.
