battery pack

Rechargeable energy source

A battery pack is a portable, self-contained power source combining multiple battery cells into a single unit.

Battery packs power devices from laptops to electric vehicles, and portable versions charge phones and tablets on the go: I always carry a battery pack when traveling.

The term emphasizes the unit's modularity—it can be swapped, recharged, or replaced independently.
