It also functions as a multi-purpose tool, doubling as a power bank for USB devices and featuring a 100-lumen LED flashlight with multiple modes, including emergency strobe and SOS.

The GB40’s lithium battery can provide up to 20 jump starts on a single charge and recharges quickly via USB-C in about three hours. Some users might find the lack of an included wall charger inconvenient, and the relatively short 24-inch booster cables might pose a challenge in some scenarios.
