/viewtopic.php?f=34&t=89255I bought the Gooloo 15,000 mAH/600 amp peak for $43 delivered.
Haven't used it on a car or truck but it was great for jump starting two of my Harleys before I installed the new batteries.
Would be a must have on a trip.
Plus can charge a phone or laptop, has a pretty bright built in LED flashlight that can blink out S-O-S
