Description

The GB250 Boost Max is one of the most powerful lithium jump starters ever designed, delivering an incredible 5,250 amps of peak starting power to jump start gasoline and diesel engines up to 16 liters. Engineered specifically for commercial and industrial use, it starts the largest Class 8 trucks, buses, motorhomes, agricultural equipment, construction machinery, mining vehicles, and vocational fleets—covering 6, 8, 12, and even 16-cylinder engines with ease. At the core of its safety system is NOCO’s patented UltraSafe Technology, featuring spark-proof connections and reverse polarity protection to ensure safe, mistake-free operation on any 12-volt battery—trusted by professionals around the world. Despite its immense power, the GB250 weighs just 15 pounds, replacing bulky, outdated alternatives with a compact, portable design that fits in its custom EVA protective case. It also functions as a portable power bank with integrated USB output to charge smartphones, tablets, and other essential devices, and recharges fully in just 4 hours using the included 56W power adapter. For added utility, it features a precision-engineered 600-lumen LED flashlight with seven light modes—including SOS and emergency strobe—making it ideal for roadside repairs, emergency response, and low-light work environments. Included in the box are the GB250 12V UltraSafe Lithium Jump Starter, 56W XGC power adapter, four interchangeable AC cords (Australia, Europe, North America, United Kingdom), XGC extension cables, and a Max Protection EVA Case. Backed by a 1-year limited warranty and engineered in the USA, the GB250 is the ultimate professional-grade solution when failure is not an option.
