Same problem here, The pineapple and 4GB SanDisk Cruzer Fit works ok when running it on the house mains power supply but it don't work on the juice pack to be able to take it outside when its all set up in the box that all comes with the elite package, I would say its only on the edge of powering up the 4GB SanDisk Cruzer Fit and not which in time could maybe cause the Sandisk 4GB Cruzer Fit to fail. Thanks for the quick reply from the team it will be nice to see how we can resolve this issue kind regards jase
