Powerful Jump-Starting Performance
At the heart of the NOCO Boost GB40 is its ability to instantly start dead batteries. With 1000 amps of peak lithium power, it is capable of jump-starting gasoline engines up to 6.0 liters and diesel engines up to 3.0 liters. This makes it suitable for most cars, SUVs, motorcycles, boats, and light trucks.
The internal lithium battery is designed to deliver strong bursts of power exactly when needed. A single charge can support multiple jump starts, which is especially useful in cold weather or during extended road trips where battery strain is more common.
Consistent Power When It Matters
Unlike traditional jumper cables that depend on another vehicle, the GB40 operates independently. This independence allows drivers to handle battery issues without waiting for roadside assistance or help from other vehicles.
UltraSafe Technology for Secure Connections
Safety is a defining feature of the NOCO Boost GB40. It is engineered with patented UltraSafe technology, including spark-proof connections and reverse polarity protection. These features help prevent sparks and reduce the risk of damage caused by incorrect clamp connections.
This design approach makes the jump-starting process more approachable, even for users with limited automotive experience. Clear indicators and built-in protection systems contribute to a stress-free experience during emergencies.
Compact, Lightweight, and Travel-Friendly
Despite its strong output, the NOCO Boost GB40 maintains a compact and lightweight form factor. Weighing approximately 2.5 pounds, it can be easily stored in a glove compartment, backpack, or emergency bag without taking up much space.
Its small size makes it ideal for drivers who want preparedness without carrying bulky equipment. Whether kept in a car, RV, or boat, the GB40 remains easy to transport and store.
Advanced Lithium Battery Technology
The GB40 uses high-discharge lithium battery technology, allowing it to deliver high power output while maintaining efficiency. Lithium batteries are known for their ability to hold a charge for extended periods, making them suitable for emergency devices that may not be used frequently.
This technology supports reliable performance and long-term readiness, ensuring the device remains useful even after months of storage.
Built-In Portable Power Bank
In addition to jump-starting vehicles, the NOCO Boost GB40 doubles as a portable power bank. It can recharge USB-powered devices such as smartphones, tablets, GPS units, wireless headphones, and other small electronics.
This feature adds everyday value, especially during travel, outdoor activities, or power outages, where access to charging outlets may be limited.
Fast and Convenient Recharging
The device can be recharged in approximately three hours using the included USB-C charging cable. This fast recharge time makes it easy to keep the GB40 ready for use with minimal effort.

Rugged and Durable Construction
Durability is essential for emergency equipment, and the GB40 is built with a rugged IP65-rated housing. This construction helps protect the device from water, dust, and minor impacts.
The rubberized exterior improves grip and adds an extra layer of protection, making the jump starter suitable for outdoor and automotive environments.
High-Conductivity Clamps for Efficient Energy Transfer
