1. Outdoors There is a dangerous design flaw in the DieHard Portable Power 1150. I have called six different numbers at Sears, including Customer Service, without finding anyone who could discuss the danger or tell me who I should call to discuss it. When the user energizes the USB charging port, they also energize the battery clamps. If I am charging a cell phone and someone touches the clamps, they could be severely injured. The USB port and the clamps should be controlled by separate switches. I should also have been able to discuss my concern with a knowledgeable person long before this.
