The NOCO GB70 is a 2,000-amp lithium-ion jump starter pack for cars, trucks, boats and RVs with gas engines up to 8 liters and diesel engines up to 6 liters. It claims up to 40 jump starts per charge, spark-proof connections and reverse polarity protection, so it can be hooked up without worrying about the clamps. It doubles as a power bank for USB devices and a 12V source for tire inflators and inverters, and it has a 400-lumen LED light with seven modes. Against smaller packs like the GB40 it is built for larger engines; against cheaper no-name boosters its safety circuitry and brand support are the main draw.
