What is an advantage of using a portable pump in firefighting?

Using a portable pump in firefighting provides significant advantages in terms of transportation. The ability to easily move a portable pump to remote or difficult-to-access areas is crucial in scenarios where fixed water supply systems are unavailable or inadequate. Firefighters often encounter situations in wildland firefighting or in rural settings where access to a water source is limited. A portable pump's lightweight and compact design make it easy for responders to carry or transport on vehicles, allowing for rapid deployment exactly where it’s needed most.

The other options don't particularly align with the primary benefits of portable pumps. While higher pressure output can be a feature of some portable pumps, it is not universally true for all, and portability remains the primary focus. Additionally, portable pumps do not inherently increase water storage, since they rely on nearby sources rather than storing water themselves. Automatic operation might be a feature of some pumps, but it is not the hallmark advantage that portability represents in firefighting contexts.
