The NOCO GB40 is a 1000A 12V lithium jump starter that also works as a USB power bank and a 100-lumen flashlight. It is rated to start gas engines up to 6 liters and diesel engines up to 3 liters, with spark-proof connections and reverse polarity protection so the clamps can be attached without worrying about order. The kit adds a 40-inch USB cable, a 12V car charger, heavy-duty clamps and a microfiber storage bag. It suits drivers who want a compact booster they can leave in the trunk, and it competes with larger, higher-amp boosters that cost more and weigh more but start bigger engines.
