The NOCO Boost Plus GB40 is a 1000-amp lithium jump starter pack for 12-volt vehicle batteries. It is rated for gasoline engines up to 6 liters and diesel up to 3 liters, and NOCO claims up to 20 jump starts per charge. It also works as a USB power bank and a 100-lumen LED flashlight with seven modes. Its main edge over rival packs is the UltraSafe circuitry: spark-proof clamps and reverse polarity protection, so a wrong connection does not damage the unit or the vehicle. It is a strong pick for a glovebox or trunk pack for a car, SUV or small truck, though the 1000-amp rating is modest for large diesel engines.

Owners widely praise the GB40 for starting cars, SUVs and small trucks on the first try and for the confidence of the safety circuitry. Complaints center on short cables, slow recharging and units that arrive with a partial charge or fail after long storage.
