NOCO Boost GB70

The NOCO Boost GB70 is a heavy-duty portable jump starter designed for those who need reliable power for larger engines. In our hands-on testing, this 2000A lithium battery booster proved capable of reliably turning over 8.0L gas engines and 6.0L diesel engines, making it a versatile tool for truck owners and road trippers. Unlike smaller units, the GB70 feels robust and durable, featuring high-quality clamps that provide a secure connection to battery terminals. Its integrated 400-lumen LED flashlight is a practical addition for nighttime emergencies, providing enough illumination to see under the hood clearly. We found the unit to be quite intuitive, with safety features that prevent sparking or reverse polarity connections. It also doubles as a power bank for mobile devices, though its primary focus remains vehicle recovery. While it excels in performance, the unit is significantly bulkier than entry-level lithium jumpers, which may be a drawback for those looking to store it in a glove box. It is best suited for vehicle owners who prioritize raw cranking power and safety features over compact portability. For those with smaller vehicles, it may be overkill, but for heavy-duty applications, it is a proven workhorse.
