Top Comments
Car engines typically need:
* 200–400A for small/medium engines
* 400–700A for large engines or diesel
The Peak power delivered can be estimated briefly:
P = V × I = 12V × 1500A = 18,000W (for millisecs!)
Engine start typically takes 1–3 seconds of cranking.
* Even at 400A for 3 seconds:
12V × 400A × (3s / 3600s) ≈ 4Wh
That's a small fraction of the 37Wh available.
If this jump starter really has 37wH in store when fully charged, it should be good to start the car.
CCA is battery health. You can have a fully charged battery and still not be able to start your car or even crank if the battery health (CCA) is too low. In that case, you need a new battery, full stop.
Also, this unit also states its normal range is 300-500A. Not sure when exactly the 1500A comes in, but it can't be that fake when others out there claim A LOT higher, like 5000A in similar sized units. And yes, parasitic drain IS a typical or at least common type of drain many people use these for even if its purpose is for "emergencies." Your experience is just one, the exception, not the rule and the reviews reflect that as does my own personal experience with it.

The only thing is that over the time battery may become weaker if this product and you have only one shot to use this and would recommend a bigger battery version.
