Thanks but I bet its just another cable. Like the Powerline II
Currently the Dura is Lightning only.
One thought though I had, which i don't think is the Oct 4th / April 10th announcement, was based on a family member's reaction to a power outage we had last night. I had kitted out the family with a Powercore Fusion each, 3 of us are Android and one of is iphone. The iphone user's view was to state they'd simply go to bed with the Fusion plugged into power and a lightning cable to iphone and so at least they wake in the morning with a charged iphone, buf if the power came on during the night then they'd also wake with a charged Fusion. Or, "a Fusion with the cable is all I need". That then made me think if you merge in a charger with a portable charger it is only lacking a cable, so why not include the cable?
Then from my metered testing of cables there is a puzzle that 2.4A output becomes 2.2A and 3A becomes 2.8A and so it must contain some losses in the USB side of the connection, so if you soldered the cable in you'd get less losses, so if you literally just had a charger with some battery with a ligntning cable combined you'd have "all you need". Now the usual problem with combined cables+chargers is the cable fails more commonly, so if you merge in the cable you'd have probably more total overall failures of a higher cost item than just a cable, but if you combined in the Dura II manufacturing process of more reliable cables, then possibly you could manufacture a combined charger+battery+cable where the components all age and fail about the same time.
i.e. if you merge this idea
with this idea
If you made the cable neatly tidy away, say with this idea
You'd then have one product you go with which is all you need, if away from the wall you plug in to the cable and when near a wall socket you'd plug in there also.
