Watched this review yesterday and bought a couple of the Avapow 4000's as they were a smoking deal on Amazon black Friday sale. we will see how they do.
Walmart had these for $68 I bought one and so far impressed. Started a completely dead 220 horse tractor and the 83 mack dump truck. It struggled on the tractor but a few trys it worked.
Gooloo jump starters.
