Assuming I could peel the casing off a micro USB cable so it could fit into the slot along with the HDMI cable beside it and splice a battery pack (3 volt?) to the other end of thwe USB cable.
Questions pertaining to this idea:
Could that be used to preserve the tether either while moving the ATV to the TV or when the power goes out?
Will the batteries try to charge while the ATV is powered through AC and eventually overcharge and fail?
Is 3 volts enough?
Iphones, Ipods, etc. have charging circuits on the battery, could that be used?
Any responses on why this wont work or on how to improve it would be welcome. This is only an idea and I wont feel bad if it’s a lame one.
