Comprehensive design, materials, and everyday usability
The NOCO Boost Plus GB20 is the undisputed benchmark for automotive emergency self-reliance, eliminating the dread of discovering a dead car battery in dark parking lots, sub-zero winter mornings, or remote road trip locations. Rated at 500 peak amps, this compact handheld jump box delivers up to 20 jump starts on a single charge, providing the instantaneous electrical surge needed to crank gasoline engines up to 4.0 liters—including passenger sedans, hatchbacks, compact SUVs, motorcycles, ATVs, and lawnmowers.
Safety is the cornerstone of NOCO's engineering. The GB20 integrates patented UltraSafe spark-proof technology and reverse polarity protection, making incorrect hookups completely fail-safe. If you accidentally connect the clamps to the wrong battery terminals, the unit automatically locks out current flow and illuminates a warning indicator without generating sparks, smoking, or damaging sensitive vehicle computer modules. Heavy-duty needle-nose battery clamps feature high-tension springs that bite securely through corrosion on battery posts.
Beyond reviving dead batteries, the GB20 serves as a comprehensive travel lifeline. An internal USB port outputs 2.1A to recharge smartphones, tablets, and wearable devices multiple times. An ultra-bright 100-lumen tactical LED flashlight features seven operational modes, including SOS and emergency emergency strobe. Ruggedized with an IP65 water-resistant casing, rubberized overmold, and rugged port covers, it withstands drops, dirt, rain, and extremes from -4°F to 122°F.
