I own two GB40 units. They are sturdy and reliable and are kept in my vehicles as a backup power source. I relied on one to limp home on a family road trip after a car battery failed unexpectedly early, and I needed to get to the dealership for a replacement. It provides plenty of power, easy to use, and dependable.
