Real-World Performance
In real-world testing, the NOCO Boost Plus GB40 proved its worth across multiple vehicle types and weather conditions. We tested it on a completely drained car battery on a cold morning, and it delivered a successful jump start on the very first attempt — no hesitation, no sparks, no complications. The UltraSafe technology truly lives up to its name, making it accessible even for users who have never used a jump starter before.
The built-in power bank came in handy during a long camping trip, successfully charging a smartphone twice on a single charge. The LED flashlight with SOS mode added an extra layer of security during a nighttime roadside check. For everyday drivers and outdoor enthusiasts, the NOCO Boost Plus GB40 genuinely delivers on every promise made on the box.

Who Should Buy the NOCO Boost Plus GB40?
This jump starter is the perfect choice for everyday drivers, road trippers, boat owners, and anyone who wants a reliable emergency tool in their vehicle at all times. It’s especially well-suited for those who also want a portable charger and flashlight rolled into one compact device. If you own a standard car, SUV, motorcycle, or ATV, the NOCO Boost Plus GB40 is without question one of the smartest investments you can make for roadside safety and peace of mind.
However, if you drive a heavy-duty diesel truck or require a jump starter with larger amp output, you may want to consider a more powerful model from the NOCO lineup. For the vast majority of everyday drivers though, this unit hits the perfect sweet spot between power, portability, and price.
