This capability allows drivers to regain mobility without relying on another vehicle or roadside service provider.
UltraSafe Technology
One of the most notable aspects of the GB40 is NOCO's UltraSafe technology. Traditional jumper cables can be intimidating for inexperienced users due to concerns about sparks or incorrect connections.
The UltraSafe design incorporates multiple protective features intended to simplify the jump-starting process and reduce user concerns.

The GB40 is more than a jump starter. It also functions as a portable power bank capable of charging smartphones, tablets, and other USB-powered devices.
This versatility increases its usefulness during road trips, power outages, and travel situations where access to charging outlets may be limited.
