Quick boost for a dead battery, compact enough to store, and the light helped us change a tire at night. Relief in one device.

Plugged in, set pressure, and walked away—came back to a perfect tire. Super straightforward for non-mechanics like me.

Useful but wish the charging cable options were more varied; still a solid emergency tool that earned its spot in my trunk.
