The NOCO Boost X GBX45 is a 12V lithium jump starter rated at 1250 amps, built for engines up to 6.5L gasoline and 4.0L diesel. Its standout feature is USB-C Power Delivery at 60W in and out, so it doubles as a fast power bank for phones, tablets and laptops and can recharge itself in about 48 minutes. UltraSafe 2.0 adds spark-proof clamps and reverse polarity protection with improved thermal management. It suits drivers of cars, trucks, SUVs, boats and RVs who want one compact pack for both jump starting and device charging; rivals in this class often charge more slowly and lack USB-C PD output.
