Title: Great for charging a cell phone, but jump starting a car?
Review: This product has never worked even on my small sized Miata battery. Regular jump starting allowed my car to start right up, but this device, used as instructed, fails to build up enough of a charge to restart vehicle. So, great for cell phones, but I need something with a lot more punch. And without the 15 minute wait time while it charges, or doesn't charge, your battery.
