How do you know when the power bank is completely charged?

Thank you for your inquiry This jump starter pack has 4 indicator lights. When the jump starter is charging, the indicator light will flash. When the light is solid on, it means that the battery is fully charged, When all 4 lights are on, it means that it is 100% charged

What are the starting amps (not peak amps)?

Back of this device says Start Current: 450 Amps; Peak Current: 3000 Amps.

Will this car starter work in -15 degree weather?

The description of the manual under below Operating Temperature -20℃～+60℃ I asked the factory engineer, the answer is -20 ℃ is also .Whether it is freezing winter or scorching summer, this battery booster can work for your protection.

Do i need to follow the starting amps(450) or peak amps(3000) to crack my suv?

You connect it and either it's going to start your vehicle or it won't.
