What would the point of 4000A peak current be? It's well beyond what might be useful to jump start an automobile?

"The peak amp figure printed on a jump starter's box is often the least useful number for deciding whether it can actually start your car. It measures a maximum current burst lasting a fraction of a second, not the sustained current a battery needs to crank an engine. What actually determines whether a jump starter is sized correctly is closer to Cold Cranking Amps and the engine's displacement, not the biggest number on the packaging."

This one has a 800amp (3 secs), then 500 amp (5 secs).

Thanks for your post. When shopping for a good jump starter, where are those numbers found and how are they calculated? How can a shopper compare one from another from product listings or other sources to see which is the best choice? Thanks.

By watching review videos rather than relying on potentially BS figures posted by manufacturers.
Project Farm does a good video on these jump starters

Should I return the one they had the other day for $70 which is this model minus the extra features? All I care about is a jump starter

What is the difference between this model (with the "Plus" designation) and the regular GP4000?
