Answer:
When choosing a jump starter, terms like Peak Current (Amps), CA (Cranking Amps, Starting Current), and CCA (Cold Cranking Amps) may confuse you a lot. With the help of the following information, you can have a better understanding of the HULKMAN Alpha jump starter.
About peak current (amps)
Peak current (amps) is defined as the maximum current that a jump starter can discharge initially, normally for a very short period of time.
What does peak current mean to jump starter?
Most people think that the higher the peak current, the better the performance of the jump starter, which is WRONG. Actually, this is irrelevant to the factors concerning starting a car. As long as the required starting current is below the peak current, it can meet the needs of users.
How to measure and evaluate the performance of a jump starter?
We use the cranking current to measure the performance of a jump starter. The larger the engine rating, the higher the cranking current that the vehicle requires.
