I'd been made aware of these by the local AutoOne guys, so I checked out the video. Obviously has the grunt required to crank over that beast.
Two things in that video did get my attention:
1. He attached the negative lead to the battery terminal. Best practice is to attach it to
the block somewhere convenient, and not too far from the starter motor - to bypass the negative terminal, lead and connection at
the block, all of which may have suspect connections that would make starting harder (or impossible).
2. More importantly, once started he removed the jumper positive lead from the vehicle's positive lead terminal while the vehicle battery was still not connected. The battery plays an important part in the regulation/filtering process, so vehicle electrics could easily be exposed to transients, especially the "dump" from the starter motor when it is released.
But the device itself looks the goods.
