    It's the only hot item in the airplane. Direct wire from the battery through a five amp fuse to the lighter. Then one wire to ground in the belly of the airplane. I wonder if a better/different ground would help?

    Try the Incase High Speed Charger sold thru the Apple Store. Your problem sounds like what many of us were discussing a year ago on this forum.

    Solved with the Incase single port. I rotate between my Ipad mini and Stratus.

    Yes I am aware it is a direct line from the battery, as I built the thing, but that's the mystery, as it shouldn't back feed ??

    Sorry, missed you were an EX guy! Have you tried another charger/cable? I have heard that some cables are grounded much better than others. I would ry a few different combinations and see if it makes it better. When I used my phone charger I didn't notice any problems with my Bose.
