These are great BUT the GB20 is probably a little weak "The 400A model is designed for motorcycles, ATVs, lawn mowers, and cars with engines up to 4.0L. " I use the GB40 and it starts my 5.7L Corvette no problem. The GB40 is $100 on or go for the GB50 on WOOT for $120
Before purchasing this brand, check out the Project Farm youtube video on jump starters. This brand came in near the bottom of the pack and was almost useless.
