This is the last item I think we may need for support on the trip - actually any trip. Now I have a compressor, a screwdriver and duct tape, what else could you need. Twice my truck has failed to start and both times I was able to use jumpers to get started. Off in some National Forest miles from help and surrounded by hungry bears I don’t want Cindy to have to walk for help so I bought this little charger. I have not used it but it was highly rated on two different web sites. It is well packed, small and light weight. It has power to jump a battery 10 times if fully charged and it will do cell phones, laptops, etc. So when it went on one of Amazon’s special day sales I bought it. I would be glad if I never have to use it but even happier if I do and it works! Seems like a great thing to carry not just while camping but on most trips.
