text: I have a similar device that has saved my bacon several times, but it came in a flimsy notebook-style case and everything is always sliding out. The JACO comes in nice clamshell case that nothing falls out of even when it's open, and everything fits back inside nicely. Very good design. The feature I most appreciate is the indicator lights that tell you a) the battery you're trying to jump is too dead or b) you have it hooked up wrong. This could save someone a lot of heartache. I strongly recommend this jump starter. One should be in every vehicle. Now I have one in both of mine.
