It really is the amount of power you need to start your engine in any weather except winter. However, CCA is used to rate the starting performance of lead-acid battery products' in cold climates, and we normally will not use it to rate your device, which is a lithium-ion jump starter. Generally, we will use the peak current to measure the jump starter’s performance. Therefore, the peak current of Alpha 100 is 4000 Amps. **Q: How many cold cranking amps? I see you refused to answer this question in the past, so I assume this product is junk. If not, then give an answer.** A: 900 amp **Q: The hulkman website specs claims 32000mah(118wh) capacity. which value is actually correct given (mah)*(v)/1000 = (wh) using 12v?** A: Not sure what your after with all the math calculations. In real world started a heavy duty 2500hd diesel that was sitting for 5 plus months. If you know diesel trucks then you know this thing has plenty of cranking amps. Pie =3.14 lol **Q: How long are the jumper cables?** A: Thank you for your interest in HULKMAN! The cable length of 40cm/15.7in for each side, is sufficient to reach both battery terminals for almost all car models. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great unit *by S***D on April 26, 2026* One of the best units on the market and well worth the price.
