The Noco GB40 is a lithium-ion jump starter pack rated at 1,000 peak amps. It starts gas engines up to 6 liters and diesel engines up to 3 liters, and holds enough charge for up to 20 jump starts. Its spark-proof clamps and reverse polarity protection make it safe for people who have never jumped a car before. It also works as a USB power bank and has a built-in LED flashlight. Against bigger boosters like the GB70, it trades starting power for a smaller, lighter pack that fits in a glovebox.
