About this item- HIGH-PERFORMANCE JUMP STARTING - The car jumper starter portable pack has a 45C high-rate lithium battery that can start 6.0 L gas/3.0 L diesel engines and other 12 V vehicles like motorcycles, cars, SUVs, pickups, or lawnmowers.This jump starter's powerful 1500 A peak suit current quickly starts low-voltage and fully-drained batteries, stocking stuffers for men and women.
- ULTRA POWERFUL BOOST - The smart boost mode automatically detects the battery's voltage. When the voltage is less than 9 V, the indicator flashes green; this unlocks the "BOOST" button, which can be pressed to start fully-drained batteries.
- QUALITY METAL CALMPS FOR IMPROVED PROTECTION - The safety metal clamps and smart jumper cable better protect the S8 Car Battery Jump Starter from excessive heat damage, loose ports, battery bulging, battery expansion, and more.
- COMPREHENSIVE SAFETY - This portable battery jumper starter has 8 integrated protections including reverse polarity, reverse connection, overcurrent, overvoltage, overload, overcharge, over discharge, and short circuit protection. Ensure your trip is safe and smooth.
- PORTABLE & COMPACT - With an overall size of 7.9*4.5*3.7" and a item weight of 0.95 lbs, it is very easy to store in a car or a travel bag. Compared with bulky lead-acid jump starters, this compact jump starter brings more convenience and peace of mind to your trip.
- 5-IN-1 MULTIFUNCTION - This device functions as a jump starter, portable power bank, and an LED flashlight with 3 modes (flashlight, strobe, SOS). The AstroAI Lithium Battery Jump Starter is your reliable, all-around trip companion here to gear you up for every adventure.

Listed on the box which they dont show a picture of. Don't buy if you have anything bigger than a 4 cylinder car.
I bought the S8 Ultra that is listed as 4000A (reality 800 CCA) and that was able to jump our V-6 with no battery attached at all no issues. Go for a step up from this unless you have a compact car or hybrid.
It's 300CCA and performs just like that. Unable to crank a 3.5L V-6 with mostly dead battery. For a non-dead battery just left the lights on...maybe this will work

Perhaps what I'm missing here and in other threads for jump boxes is how to compute CCA's out of xxxxA and xxwh's?
It seems as if there is no way to accurately compare one against another?

It's not a simple Ohms law calculation using voltage and amperage since they are measuring some form of "instantaneous" peak amperage which is how they come up with a peak 1500a rating that no one is required to call them out on.

Peak Amps (Theoretical Maximum)
Peak amps is the instantaneous burst of current the unit can deliver under ideal, momentary conditions — essentially measured across a dead short for a fraction of a second. It's:
- Tested at room temperature with no load resistance
- Measured in milliseconds — not a sustained output
- Largely a marketing metric with no standardized test method
- Can be inflated by manufacturers since there's no governing standard
Cold Cranking Amps (CCA)CCA is a standardized, real-world metric defined by the Battery Council International (BCI):
