I bought a very big DeWalt “power station”
It will jump-start just about anything, and will crank for a long time compared to many others.
It also has a tire pump, and 120v power outerlets, and USB power outlets
2800 “peak” amps
1000W Inverter, 120 PSI Air Compressor
It is heavy.
Overkill, maybe, but it has come in handy for me and my neighbors.
