1st Use In 5 Years
Bought my GB40 ~5yrs ago. After waiting in a 2-hour long COVID testing queue this morning with radio on, constant stop/start, the battery finally gave out. With ~500 cars behind me, pulled this thing out of the glovebox, not having been charged in 2yrs, it still had 50% charge. Hooked it up in 30secs, engine cranked first time, problem solved in under 2mins. Best $100 i've ever spent.
Yes, I recommend this product.
