I bought the above mentioned item and have never used it. It is a portable power source (charger) which is to be kept in a 'charged state' to be used in case of emergency. THE PROBLEM IS THAT THE UNIT DOES NOT HOLD A CHARGE, THEREBY RENDERING IT A$100.00 DOOR STOP. I have shopped at Sears for decades and always bought with the confidence that they would stand by their products. When I returned the item I was told that the 1year was up, and unceremoniously shown the door. It goes without saying that I am livid. Can you please help me find some just resolution to this problem? Thank you.
