Buyer notes
I used the FASTⅡ to start my heavy-duty truck in the middle of a cold snap, and it turned over the 7L diesel engine instantly.
The Quick Charge 3.0 port is a lifesaver for my phone, and the lithium jump box is small enough to keep under my seat.
The LED flashlight is incredibly bright, which made it easy to see the 12V battery terminals during a late-night breakdown.
