Unfortunately, I don't have any "action shots" but I have used it for cooks from start to finish and it worked like a dream.
This is why I was asking for pics of the 12V charging cord on the other unit. If the end will fit in the Guru, then you can power your Guru directly from the 12V plug on your jump starter.
