They probably mean “pack the essentials” — bring only the most important stuff you need. It’s a casual way of saying: take the basics, not a lot of extra items. The general meaning of “pack” is to put things into a bag or container, and “pack it in” can also mean stop or quit, depending on context.

How it’s used

  • “Pack the essentials for the trip” = bring the necessary items.
  • “I only packed the essentials” = I brought the basics.
  • In some contexts, “pack it in” means stop doing something, but that’s different from “pack the essentials”.

Example

“Don’t overthink it—just pack the essentials: phone, charger, ID, and a change of clothes.”

Note

If you saw it in a text or comment and it looked misspelled as “pack the ecessals,” they almost certainly meant “pack the essentials.”
