I have one in my truck, my wife has one and the other is a spare.

After you have jumped off your diesel let me know. While battery design has progressed greatly lately up to the LiPo type the current needs to jump start a vehicle are just not there, yet. If it was advertised as an emergency power source, OK. Look at the size of the wires? Big enough to carry the 3-400 amps needed. Not at all. Ohms law is a law and not a suggestion.
While their demo was interesting it proved nothing. A load rating using current testing equipment would convince me. Run your Miracle battery by Wally World and have them load test it for you. Might be interesting.
