Which one do you choose?

If you have two car jump starters: One is large, the peak current is 1700A; The other volume is small, easy to carry, the peak current is 400A. For you, which one you prefer to choose a large current or a portable jump starter (https://goo.gl/SVqXE8)?

400CCA is enough to start a small car, the 1700cca will be enough to start a truck.

The advantage of the 1700cca is you'll be able to let it get a little drained before it becomes useless.

Thank you Matt.
