The NOCO Boost Plus GB40 is a compact yet powerful battery jump starter designed for both gasoline and diesel engines. With a peak output of 1000 amps, it can jump start most vehicles quickly and efficiently, allowing for up to 20 jump starts on a single charge. This feature is particularly beneficial for drivers who require a reliable backup during emergencies.

One of the standout aspects of the GB40 is its safety features. It incorporates a mistake-proof design, including spark-proof technology and reverse polarity protection, which makes it easy to use, even for those who might be unfamiliar with jump starting a vehicle. This focus on safety is a significant advantage in the battery jump starter category.

In addition to being a jumper, it doubles as a portable power bank, allowing users to charge smartphones and other USB devices. The built-in 100-lumen LED flashlight with multiple modes, including SOS, adds extra functionality, making it a versatile tool for roadside emergencies. Portability is another strong point; the unit is lightweight at just 2.5 pounds and features a rugged, water-resistant design, rated IP65, ensuring durability in various weather conditions. However, while it is compact for a jump starter, some may find it a bit bulkier than simpler models. On the downside, the GB40's battery capacity may not be enough for larger or more demanding vehicles, particularly those with bigger engines outside its stated limits. It's also important to note that while it has a robust build, the price might be on the higher side compared to less feature-rich alternatives.
