Will this jack fit under my car without a jack pad?

Always use a jack pad or block of wood between the jack head and the vehicle's frame or lift point. Bottle jacks need a flat, solid contact surface to prevent slipping and frame damage.

Can I use this jack for sustained work, or just quick lifts?

Bottle jacks work best for temporary lifting — tire swaps, oil changes, quick undercarriage checks. They're not designed for extended dwell time under load. Support the vehicle on jack stands once lifted, and lower the jack between tasks.

Does it come with a handle or pump assembly?

This is the jack unit itself. Verify your existing hydraulic system or source a compatible hand pump separately if needed for your setup.
