Question

Explanation:

When unhooking a Jump Pack, safety is crucial. Shutting the unit off first prevents electrical surges or accidental short - circuits. Removing cables (positive or negative) without shutting off the unit can lead to sparks or electrical issues. Saying it doesn't matter which cable is removed first is incorrect as the proper procedure (shutting off first) is safety - oriented.

Shut the unit off
