So my old faithful jumper cables broke down and need replacement. My issue is a good set of jumper cables cost close to as much as a battery pack with jumper cables on it. Does anyone have experience with these setups? It would be easier to use and take up much less space. The jump start battery pack also has other benefits of charging/ powering USB devices when needed. I use a couple of USB fans in my RTT so this would be a benefit I could use. But do they really work for jump starting vehicles?
