Emergency tool kit must have

[EarlsflyinCobra]

A friend of mine that works at a car lot recently purchased one of these after the local tool truck showed it off; he went out onto the lot with a fully charged unit and found 12 cars with dead batteries; he started all twelve without problem and the battery charge indicator on the unit only went down one light; he has also used it to start a jet ski without a battery in it; you can also use it to charge your phone, laptop, etc.; I plan on adding one to my roadside tool kit as soon as possible.

Must be some pretty good technology going on there. Plenty compact and amazingly inexpensive. I have a 12,000mAH emergency power thingy for my phone and Kindle but I never thought that would be anywhere near enough to crank an engine, much less, a bunch of them. Hope someone with electronics knowledge chimes in with their thoughts.
