Impressive battery jump pack

[hayden]

We have a Deere 650 dozer here for some work around the house, and its alternator died. A week later after replacing the alternator, the battery was dead. All it would give was a click click. I broke out a small lithium ion jump pack that I bought sometime in the past year, but never had a need to use. We were very skeptical because it's barely any larger than a full size multi meter. I hooked it up, we waited maybe 30 seconds, and the dozer fired right up. Very impressive.

Seldom do the tow truck guys use jumper cables anymore…

Quicker with a jump pack..,

There is enough energy in one of those to start a wicked fire!

I have at least 3 jump starters/air compressors, use them a lot. But wouldn't start my tractor the other day with a dead battery.
