Jump Starters
Portable battery packs that start a dead car without another vehicle
A portable jump starter is a battery pack with clamps that can start a car with a dead battery, no second vehicle needed. Many double as power banks with USB ports and built-in lights, making them handy for emergencies. The right size depends on your engine type, since larger engines need more starting power.
When choosing, match the peak amps and capacity to your engine, and check the safety features that prevent sparks and reverse polarity. We curate top-rated jump starters on Amazon so you can compare units sized for cars, trucks, or larger engines. A unit that holds charge over months is worth keeping in the trunk.
