Eton Boost Solar Review:


Everyday functionality + solar!

I've grown strongly attached to my Boost Solar. The solar functionality is amazing! There is even a light that blink while charging via solar, to further instill confidence that the product is charging.

I love being able to remove the battery from the solar panel. This makes using this 5000mAh battery even easier to carry with me anywhere I need to go without needing to carry the whole solar panel if it is not needed.

The feel, form, and function of this far exceeds that of other similar units that I have tried. The high water and impact resistance is only confidence inspiring!
