Bests & Worsts Reviews from Amazon

I dont write reviews much but, this needed to be said about this product. I have had it about a year now and goes everywhere with me. 2 weeks ago im charging my phone and bluetooth speaker while walking in the woods with my dog on our property, as i lift many 16ozer's During the day and night I dont realized that i misplaced it, until morning after a Long day of cold rain. Couldn't find it in camper so I assume i dropped in the woods. well 2 weeks later after many days of rain ice and snow, with temps between 29f and 40 f I was walking though woods again when my dog happened upon it, frozen but still able to produce 1 led light. brought in camper, warmed it up for a while and charged it up. i Can honestly say that it is charging my phone right now while righting this review. great product.
