On a family vacation in our RV, we arrived at the Hershey Park Campground in bad weather and rushed to set up. I accidentally left my plug-in cooler running in my truck over night. In the morning, we got up early to go to the Park and the battery was dead.
With the sinking feeling that we were going to lose the better part of the morning, a campground maintenance vehicle came by to offer assistance. He pulled out a JNC660 they keep handy for various uses and in less than a minute our truck was running! I was impressed that that little thing can start a large engine easily. Two days later, we arrived home and I bought my own JNC660. Now, I leave my jumper cables in the garage and the JNC660 goes with us on trips.
Thanks for a great, reliable and affordable product.
