They work great.So do these types of things now take the place of jumper cables?
Not sure this would work in the AZ summer, as it's only rated to 104* F.
Our summers often get above 110* for days and days on end, meaning the temp inside the truck will be well beyond that.

The operating temperature of GP4000 is under -4°F~104°F(-20°C~40°C).
I have one in each of our vehicles.
