Editor's Pick: If your car sits in the parking lot too long and won't start, there's no need to hunt around for someone to jump it. Just clamp it onto the battery and you're good to go. With 4000A peak current, it can handle both gas and diesel vehicles. It also doubles as a large power bank, and with 100W bidirectional fast charging, it can even power your laptop. Charging itself from empty to full takes about an hour. It's compact and doesn't take up much space in the trunk.
