Great Low Cost Save-The-Day Charger

I'm one of those "be prepared" scout type of person and I love the great low cost save-the-day charger.

Imagine being out on the water prepared for a wonderful day - and you lose your power source? Not my idea of a good time.

And wow the expense, this is not like calling AAA with your membership card in hand! I would not go out without this, ever!
