This little charger has been such a godsend to me. I'm in a new city and constantly on my phone to check directions and I've gotten nervous about my phone dying a couple of times. But having this back up in my purse has totally saved me, both from being totally lost in a new place and by giving me peace of my mind when I go out. I even dropped it, it split open, and I was able to squeeze it back together and it still works! I'm sure their might be fancier versions of this out in the world right now, but this is so cute and does exactly what I need it to. My friends are always curious where I got it. Love this thing!
