Power sources are always a topic of discussion if you are traveling with kids or on a hunt. Over the years I have done everything from purchasing products from my local Walmart to ordering cheaper versions on Amazon. Recently, I purchased the Flip 36 by Goal Zero and it has done a great job. It is light, compact, and offers multiple charges of my iPhone and/or my Garmin watch. This is just what I was looking for to round out my backcountry hunting gear for this year's hunt and I would highly recommend it.
