I purchased one, charged it for several days, etc.... When I needed to start my old van, with a dead battery, it didn't work. Perhaps mine is faulty ???, OR not sufficiently charged, etc...perhaps I didn't leave it hooked up long enough before trying.... Lights did come on, etc..but starter clicked, but wouldn't operate. The instructions say that it is useful for a slightly discharged battery....ie: I left on the lights, now my car won't start.....but not effective for a dead battery. Mine is about 12 inches long; 2" x 2 " , and includes a power socket....so I do have a reservoir for light electrical devices.... I'll give it another try when I find a sightly discharged battery*... * I suspect the definition is a battery that will slowly turn over the engine but so fast as required to start; as power is also being drawn for ignition, warning lights, etc. In an aircraft this may work better, as the ignition system is operated by magnetos, and if you get any turn over, so the magnetos spin, the aircraft engine should start. AND, it is easy to Prop start our small engines,...BUT it is dangerous for in-experienced folks, so Be careful. Don't do it by yourself....always have a qualified person in the cockpit operating the controls when prop starting.
