I have a similar jump pack. Air compressor for the toys (and the boat trailer tire!) A built in light and the best feature is a switch that you activate AFTER making the connection to the battery you are jumping. This practically eliminates the spark possibility. 500 amps of jumping power. I've never needed it to jump my own boat, but it has helped countless others.
